TECHNICAL FIELD
This disclosure relates to serotonin receptor modulators, including conformationally constrained serotonin receptor agonists, and methods of using them for treating and preventing a variety of human conditions.
BACKGROUND
Serotonin or 5-hydroxy tryptamine (5-HT) is a major neurotransmitter that is primarily found in the gastrointestinal tract, platelets, and the central nervous system (CNS). 5-HT is involved in the regulation of a variety of physiological functions, such as intestinal movements, mood, cognition, and appetite. These functions are mediated through serotonin receptors, which belong to the G-protein coupled receptor (GPCR) superfamily and are composed of seven subfamilies (5-HT1-7) and 14 isoforms.
Recently, the serotonin 2C (5-HT2C) receptor has been shown to be a promising drug target for the treatment of a variety of CNS disorders, including obesity and mental disorders, such as schizophrenia, depression, and anxiety. Furthermore, based on the study of both its distribution and biological function, 5-HT2C receptors in the basal ganglia likely are essential for the regulation of repetitive motion and in the cingulate gyrus they mediate many of the effects of neurotransmitters on obsessive/compulsive-type behaviors.
One of the many advantages of the 5-HT2C receptor as a CNS drug target stems from the fact that it is found almost exclusively in the CNS. Therefore, compounds that selectively activate this receptor should have limited impact on peripheral tissues. However, the activation of two other closely related 5-HT2 subtypes, i.e., 5-HT2A and 5-HT2B receptors, has been reported to be associated with hallucinations and cardiac valvulopathy, respectively. Therefore, the identification of ligands possessing a high selectivity against the 5-HT2A and 5-HT2B receptors is a key criterion for the therapeutic advancement of 5-HT2C agonists. This goal has been challenging due to the high conservation of molecular determinants involved in ligand recognition within this subfamily of receptors. Accordingly, there remains a need to develop safe and selective 5-HT2A receptor modulators.

Compositions and Methods
As used herein, the term “5-HT1A” refers to a 5-HT1A receptor. As used herein, the term “5-HT2A” refers to a 5-HT2A receptor. As used herein, “5-HT2C” refers to a 5-HT2C receptor.
As used herein, the term “effective amount” in connection with a compound disclosed herein means an amount capable of treating or preventing a disorder, disease or condition, or symptoms thereof, disclosed herein.
As used herein, the term “hallucination” (and related terms such as “hallucinogenic” and “hallucinogen”) refers to a perception in the absence of external stimulus that has qualities of real perception. In some embodiments, hallucinations may be vivid, substantial, and are perceived to be located in external objective space. As used herein, hallucinations may occur in any sensory modality including, but not limited to visual, auditory, olfactory, gustatory, tactile, proprioceptive, equilibrioceptive, nociceptive, thermoceptive and chronoceptive. In some embodiments, the hallucinations are selected from visual hallucinations, auditory hallucinations, olfactory hallucinations, gustatory hallucinations, tactile hallucinations, proprioceptive hallucinations, equilibrioceptive hallucinations, nociceptive hallucinations, thermoceptive hallucinations, chronoceptive hallucinations and any combination thereof. In some embodiments, hallucinations are visual hallucinations.
As used herein, the terms “prevent” or “preventing” refers to means a method of delaying and/or precluding the onset, recurrence or spread, in whole or in part, of a disorder, disease or condition; barring a subject from acquiring a disorder, disease, or condition; or reducing a subject's risk of acquiring a disorder, disease, or condition.
As used herein, the term “treat” or “treating” refers to an alleviation, in whole or in part, of a disorder, disease or condition, or one or more of the symptoms associated with a disorder, disease, or condition, or slowing or halting of further progression or worsening of those symptoms, or alleviating or eradicating the cause(s) of the disorder, disease, or condition itself.
For example, in certain embodiments, some seizures disorders are the result of genetic dysfunction, wherein therapeutic modalities for such seizures are not treating the underlying cause. Instead, in certain embodiments, “treating” such diseases or disorders may instead be affected by reducing or eliminating the symptoms of such seizures (e.g., staring spells) or the behavior associated with such.
In further embodiments of the present disclosure, described are novel compounds and compositions, as well as methods of administering the same. In some embodiments, a compound provided herein is for use in the methods provided herein. In some embodiments, the disclosure provides the use of a compound provided herein in the preparation of a medicament for treating one or more of the diseases or disorders provided herein.
In certain embodiments, the method comprises administering a serotonin 5-HT1A agonist and a serotonin 5-HT2A agonist. Without being bound to any particular theory, in certain embodiments it has been surprisingly discovered that administering a serotonin 5-HT1A agonist and a serotonin 5-HT2A agonist can be effective in preventing or treating one or more of the conditions described herein. In certain embodiments, it has also been surprisingly discovered that administering a serotonin 5-HT1A agonist and a hallucinogenic 5-HT2A agonist can effectively treat patients without the patients experiencing the hallucinogenic effects of the 5-HT2A agonist. Without intending to be bound by any particular theory, it is believed that the patient can experience a therapeutic effect without experiencing a hallucinogenic manifestation that typically results from the administration of a 5-HT2A agonist because the 5-HT1A agonist can “turn off” the hallucinogenic effects of the of the 5-HT2A agonist without otherwise significantly altering its agonism at a 5-HT2A receptor. In some embodiments, the 5-HT1A agonist is a partial agonist. In some embodiments, the 5-HT1A agonist is a full agonist. In some embodiments, the 5-HT2A agonist is a partial agonist. In some embodiments, the 5-HT2A agonist is a full agonist. In some embodiments, the 5-HT1A and/or 5-HT2A agonists may be selected from compounds of Formula I herein. In some embodiments, the 5-HT1A and the 5-HT2A agonists are the same compound (e.g., a compound of Formula I).

In certain embodiments, the method comprises administering a serotonin 5-HT2A agonist and a serotonin 5-HT2C agonist. Without being bound to any particular theory, in certain embodiments it has been surprisingly discovered that administering a serotonin 5-HT2A agonist and a serotonin 5-HT2C agonist can be effective in preventing or treating one or more of the conditions described herein.

In some embodiments, the serotonin 5-HT2A agonist and 5-HT2C agonist are administered at the same time in the same composition.

In some embodiments, the 5-HT2A agonist is selected from compounds of Formula I, such as for example compounds of Formulae II(a) or II(b).
In some embodiments, the 5-HT2A agonist and the 5-HT2C agonist may comprise the same compound. In some embodiments, the compounds of Formula I described herein (e.g., compounds of Formula I(e)) can act as both 5-HT2C and 5-HT2A receptor agonists. In some embodiments, the compounds described herein are full agonists for both 5-HT2A and 5-HT2C.
In some embodiments, the compounds described herein act as partial agonists at 5-HT2A and full agonists at 5-HT2C. In some embodiments, the compounds described herein are partial agonists for both 5-HT2A and 5-HT2C. In some embodiments, the compounds described herein act as agonists at 5-HT2A and 5-HT2C but are only partial agonists (or inactive) at a 5-HT2B receptor.
In some embodiments, the compounds of Formula I are selective agonists of 5-HT2C, wherein said compounds are more potent and/or efficacious (Emax) when compared to the other serotonin receptor subtypes (e.g., 5-HT2A and 5-HT2B). Without being bound to any particular theory, it has been surprisingly discovered that compounds of the present disclosure are orthosteric ligands of 5-HT2C that exhibit a Gq-mediated signaling bias and no/minimal β-arrestin recruitment or β-arrestin-mediated intracellular signaling. Applicant theorizes that this Gq-biased signaling mechanism results in reduced signal attenuation caused from β-arrestin recruitment, resulting in a greater therapeutic effect and fewer side effects for certain therapeutic indications (e.g., Alzheimer's psychosis, schizophrenia, addition, obesity, etc.).
In certain embodiments for compounds of Formula I, Applicant has discovered that the size and nature of alkyl groups for X and/or Y can dramatically affect the metabolism of such compounds. For example, it has been theorized that compounds such as 5-MeO-Dimethyltryptamine (5-MeO-DMT) and Dimethyltryptamine (DMT) are inactive upon oral administration due to rapid metabolism of the methylamino residues by monoamine oxidase (MAO) enzymes. It has also been theorized that the oral stability of psilocin (4-OH-dimethyltryptamine), on the other hand, is due largely to intramolecular coordination (hydrogen bonding) between the 4-OH group and the dimethylamino residue, which effectively shields/inhibits rapid MAO degradation.
Without being bound to any particular scientific theory, Applicant has surprisingly found that, in some embodiments, substituting the alkyl groups X and/or Y with substituents such as deuterium and fluorine can help inhibit MAO degradation of those groups. In addition, or in the alternative, Applicant has discovered that using non-methyl alkyl groups such as ethyl or n-propyl for X and/or Y can also slow or inhibit rapid MAO metabolism upon oral administration.
This, in turn, permits the preparation of orally available compounds of Formula I that are highly active serotonergic drugs that do not require special formulating procedures (e.g., dosages containing MAO inhibitors), or the presence of hydrogen bond-forming donors in the molecular structure that —in some cases —can negatively impact the properties of the underlying compound (e.g., reduction of 5-HT1A and/or 5-HT2A agonism).
In some embodiments, Applicant has also surprisingly discovered that deuteration of the —W1-R2 residue can help to substantially enhance the half lives of those compounds when compared to proteo (hydrogen) variants. It has been generally shown that the primary metabolites formed in the enzymatic metabolism of most phenalkylamines such as mescaline proceeds via the oxidation of the aminoalkyl residue, as shown below. Notably, the metabolism of mescaline does not proceed through the demethylation of any of the three methoxy residues:
Contrariwise, metabolism (e.g., first-pass metabolism in the liver) for compounds in some of the embodiments described herein proceeds through a previously-unidentified mechanism. Indeed, the primary metabolites of certain compounds described herein takes place on the —W1-R1 residue of those compounds, including the following exemplary study conducted in human and mouse liver microsomes showing no major metabolites resulting from the metabolism of the aminoalkyl residue. Instead, primary metabolites appear to be limited to those resulting from the dealkylation and oxidation/hydrogenation (2 oxygens/2 hydrogens gained as shown via mass spec) of the —W1-R2 residue:
In view of the foregoing, Applicant set out to slow the metabolism of such compounds in an effort to enhance pharmacokineticss (e.g., plasma half life (T1/2) and concentration (AUC)) by introducing deuterium atoms to, e.g., the alkoxy and alkylthio groups represented by the —W1-R2 residue of Formula I. Without being bound to any particular scientific theory, it is believed that the heavier deuterium isotope disrupts the enzymatic metabolism of those compounds. In certain embodiments, it is believed that activity of CYP450 enzymes is reduced by the introduction of deuterium at the sites of metabolic breakdown. However, in some embodiments it may not be desirable to “over deuterate” the compound, such as further including deuterated species for other portions of the compound, which can further alter the compounds' pharmacokinetic profiles in an undesirable manner (e.g., reduction in blood-brain barrier penetration; poor solubility in water). Accordingly, in some embodiments, Applicant has discovered that minimal deuteration may be used to achieve the desired pharmacokinetic outcome. Exemplary deuterated compounds have been previously disclosed herein, including those set forth below:
In other embodiments, the nature of the —W1-R2 residue of Formula I may result in “metabolic switching” on the molecular scaffold, which may result in primary metabolism at another site on the molecule. For example, certain compounds having the structure —W1—CF3 may hinder dealkylation of that residue, resulting in primary metabolism at the methylene group between the cyclopropyl residue and the —N(X)(Y) residue. Thus, in such embodiments, the metabolism of those analogs may be slowed by making at least one of R3 and R3′ a deuterium. An exemplary compound includes the analog demonstrated below:

As referenced herein and unless context dictates otherwise, “non-convulsive” seizures include those such as absence seizures that do not involve convulsive movements (i.e., rhythmic jerking or stiffening of muscles). While subtle motor signs such as eye fluttering or blinking, slight lip smacking, or minor hand movements may be observed in subjects presenting absence seizures, these movements would not generally be considered convulsive in nature.
In certain embodiments, it is believed that staring spells and/or loss of awareness are generally associated with a thalamocortical circuit disruption or thalamocortical oscillations. For example, in some embodiments, absence seizures are believed to arise from abnormal rhythmic oscillations between the thalamus and cerebral cortex. The thalamus, a relay center for sensory and motor signals, plays a key role in regulating consciousness and attention. In certain embodiments, these oscillations are driven by T-type calcium channels in thalamic relay neurons, which become hyperactive during seizures, leading to excessive synchronized firing. As further discussed herein, impaired GABAergic and glutamatergic signaling, ion channel dysregulation, cortical network hyperexcitability, and genetic contributions can also be associated with thalamocortical circuit disruptions.
Thalamocortical oscillations and thalamocortical circuit disruptions both involve the functional relationship between the thalamus and the cerebral cortex, yet they represent distinct physiological processes with different implications for brain function and disease. Thalamocortical oscillations refer to rhythmic patterns of neural activity that regulate various brain states, including sleep, wakefulness, and sensory processing. These oscillations arise from the dynamic interplay between thalamic relay neurons and cortical networks, producing characteristic waveforms such as sleep spindles (12-16 Hz), delta waves (1-4 Hz), and gamma oscillations (30-100 Hz). While these oscillations are essential for normal cognition and consciousness, their dysregulation can contribute to neurological disorders. In the case of absence seizures, excessive and hypersynchronous thalamocortical oscillations-particularly in the 3 Hz spike-and-wave range—are a hallmark feature. These abnormal oscillations may lead to brief periods of impaired consciousness, causing the characteristic staring spells and lack of awareness associated with the condition.
Thalamocortical circuit disruptions, on the other hand, typically involve structural or functional impairments in the connectivity between the thalamus and the cortex. Unlike oscillations, which can be part of normal physiology, circuit disruptions generally indicate pathology and are linked to a wide range of neurological conditions, including epilepsy, neurodevelopmental disorders, and neurodegenerative diseases. A disruption in this circuitry can impair the transmission of sensory, cognitive, and/or motor information, leading to deficits in attention, awareness, and sensory perception. In the context of absence seizures, while the disorder is primarily characterized by abnormal oscillations, some researchers suggest that underlying thalamocortical circuit dysfunction may contribute to the generation and propagation of these seizures. A breakdown in inhibitory or excitatory control within the thalamocortical network may predispose the system to enter the pathological rhythmic activity seen during absence seizures.
In certain embodiments, it has been surprisingly discovered that the compounds described herein (e.g., compounds of Formula I) may be effective for treating non-convulsive absence seizures and convulsive epileptic seizures. This finding is both surprising and unexpected due to fundamental neurophysiological and mechanistic differences between these seizure types. More specifically, convulsive epileptic seizures, such as tonic-clonic or focal motor seizures, are characterized by widespread cortical excitability, excessive neuronal firing, and synchronized hyperexcitability across broad cortical and subcortical networks. These seizures typically originate in the cortex and propagate to motor regions, leading to involuntary muscle contractions, loss of postural control, and violent convulsions. Historically, treatments for convulsive seizures often focus on suppressing cortical excitability, enhancing GABAergic inhibition, or blocking sodium or calcium channels to prevent excessive neuronal firing. In contrast, absence seizures, a form of non-convulsive epilepsy, arise from abnormal thalamocortical oscillations rather than cortical hyperexcitability. These seizures are typically characterized by 3 Hz spike-and-wave discharges and are thought to result from dysregulated interactions between the thalamus and cortex, specifically involving T-type calcium channel activity and aberrant GABAergic signaling within the reticular thalamic nucleus. Unlike convulsive seizures, which manifest through motor involvement, absence seizures present as brief staring episodes, loss of awareness, and behavioral arrest without significant motor convulsions.
Given the divergent neurophysiological mechanisms underlying convulsive seizures and non-convulsive absence seizures, it would not be expected that a compound effective for convulsive seizures—likely targeting cortical excitability—would also be effective in absence seizures, which arise from thalamocortical circuit dysfunction and/or oscillations rather than generalized cortical hyperexcitability.
Indeed, it has been previously known that convulsive and non-convulsive seizure disorders are subject to distinct pathophysiologies and drug targets. For example, most known drugs for treating convulsive seizures act on sodium channels (e.g., phenytoin, carbamazepine), GABA-A receptors (e.g., benzodiazepines), or glutamate receptors to suppress high-frequency cortical firing. In contrast, absence seizures have been previously known to respond preferentially to drugs that modulate T-type calcium channels (e.g., ethosuximide) or selectively alter thalamocortical rhythm generation. Many known first-line convulsive seizure treatments fail to control absence seizures and, in some cases, worsen them (e.g., phenytoin and carbamazepine can exacerbate absence seizures).
Moreover, historical precedent has largely suggested that there is limited—if any—overlap in the known treatments for convulsive and non-convulsive seizure disorders. Clinical and pharmacological data suggest that many drugs previously described as being effective for convulsive seizures are ineffective or even counterproductive in treating absence seizures. For example, sodium channel blockers, which suppress cortical excitability in convulsive epilepsy, do not typically prevent the synchronized thalamocortical oscillations seen in absence seizures. Given this precedent, the expectation would be that compounds described herein, if effective in convulsive seizures, would not necessarily modulate thalamocortical network dysfunction in a way that otherwise treats or controls absence seizures. However, contrary to this understanding, in some embodiments, Applicant has surprisingly discovered that compounds of Formula I may be effective in treating broad seizure types (e.g., convulsive and non-convulsive), suggesting an unanticipated and novel mode of action that is distinct from conventional anti-seizure medications. Additionally, this further suggests that patients with mixed seizure types (e.g., juvenile absence epilepsy with occasional convulsive episodes) could benefit from treating with compounds of Formula I rather than requiring multiple drugs, which is often necessary to manage absence seizures separately from convulsive seizures.
Given the well-established mechanistic divergence between convulsive and non-convulsive seizure types, it was not predictable that a compound having efficacy against convulsive seizures could also be effective against absence seizures (e.g., in some embodiments, via suppression of thalamocortical oscillatory disruptions). This surprising discovery further supports the novel therapeutic potential of the compounds of Formula I.
Several mutations have been associated with absence epilepsy, particularly in forms like childhood absence epilepsy (CAE) and juvenile absence epilepsy (JAE). These genes are often involved in the regulation of ion channels or neurotransmitter signaling. Some of the key genes implicated include:
CACNA1H:
Function: Encodes a T-type calcium channel subunit that regulates neuronal excitability and rhythmic thalamocortical activity.
Association: Mutations can lead to hyperexcitability in thalamic neurons, a key mechanism underlying absence seizures.
CACNA1A:
Function: Encodes a P/Q-type calcium channel subunit involved in synaptic neurotransmitter release.
Association: Mutations in this gene are also implicated in various epilepsy syndromes, including some cases of absence epilepsy.
GABRB3:
Function: Encodes the β3 subunit of the GABA-A receptor, which is responsible for inhibitory neurotransmission.
Association: Mutations or deletions in this gene reduce inhibitory signaling, contributing to the generalized spike-and-wave discharges seen in absence epilepsy.
GABRG2:
Function: Encodes the γ2 subunit of the GABA-A receptor.
Association: Mutations in this gene disrupt inhibitory GABAergic signaling, predisposing individuals to seizures.
SCN1A and SCN2A:
Function: Encode voltage-gated sodium channel subunits critical for action potential propagation.
Association: While SCN1A is more strongly associated with severe epilepsies (e.g., Dravet syndrome), mutations in SCN2A have been linked to milder epilepsy syndromes, including absence epilepsy.
SLC2A1:
Function: Encodes GLUT1, a glucose transporter essential for brain energy metabolism.
Association: Mutations in this gene can cause GLUT1 deficiency syndrome, which may present with absence seizures as part of the clinical picture.
CHRNA4:
Function: Encodes a subunit of the nicotinic acetylcholine receptor, involved in excitatory neurotransmission.
Association: Rare mutations have been identified in some families with absence epilepsy.
Absence seizures are often considered a polygenic disorder, meaning multiple genes, each with a small effect, may interact to increase susceptibility. In some cases, absence seizures exhibit an autosomal dominant inheritance pattern with incomplete penetrance. The most commonly implicated genes in absence seizures are those involved in calcium channel function (e.g., CACNA1H, CACNA1A) and GABAergic inhibition (e.g., GABRB3, GABRG2).
Some other diseases or disorders that are linked to, or otherwise have symptoms or side effects associated with, thalamocortical circuit disruption include, but are not limited to, Parkinson's disease, schizophrenia, autism spectrum disorder, ADHD, obsessive-compulsive disorder (OCD), depression, Tourette Syndrome, bipolar disorder, and multiple sclerosis.
Treatment-resistant absence epilepsy, also known as refractory or drug-resistant absence epilepsy, occurs when absence seizures fail to respond adequately to first-line antiepileptic drugs (AEDs) despite optimal treatment. In certain embodiments, this means that seizures persist even after trials of at least two appropriately chosen and dosed AEDs, either alone or in combination.
In some embodiments, the seizure disease or disorder is a Developmental Epileptic Encephalopathy. Developmental Epileptic Encephalopathies (DEEs) are a group of severe childhood-onset epilepsy syndromes characterized by frequent seizures, developmental delays, and EEG abnormalities that worsen cognitive and neurological development. Below in Table 3 is a list of common DEEs that may be treated with compounds described herein, along with brief explanations for each condition:

Following the cessation of gas evolution, a 1 M THE solution of crude product of Example 16 was added dropwise at room temperature. The reaction was quenched after 30 min by the careful addition of water and diethyl ether. The phases were separated and the aqueous phase was extracted with diethyl ether (x3). The combined organic extracts were combined and washed with water (x2) and brine, and dried with anhydrous sodium sulfate. After filtration, the solvent was removed in vacuo to provide the crude solid product that was used in the next step without purification.

The reaction mixture was allowed to stir until the reaction mixture became homogeneous (ca. 45-60 min) at which point a 1 M DMSO solution of the crude product produced in Example 17 was added dropwise. The reaction mixture was allowed to stir for at least 2 hours (or sooner if TLC indicated a complete reaction) and quenched by the addition of water and diethyl ether. The phases were separated, and the aqueous phase was extracted with diethyl ether (x3).

The reaction mixture was heated to 60° C. and stirred overnight. The reaction mixture was then allowed to cool to room temperature and diluted with diethyl ether. The phases were separated and the organics washed with sat. aq. sodium bicarbonate (x2). The combined aqueous extracts were acidified to pH=1 and extracted with dichloromethane (x3). The combined organic extracts were dried over anhydrous sodium sulfate, filtered, and concentrate in vacuo to afford the acid product as a white solid.

To a stirred solution of 365 mg of the acid product from Example 19 in DMF (0.1 M) at room temperature was added 1,1′-carbonyldiimidazole (2.0 equiv). The reaction mixture was allowed to stir at room temperature for 30 min before ammonium acetate (10 equiv) and triethyl amine (5 equiv) are added. The reaction mixture is allowed to stir at room temperature overnight before being quenched by the addition of diethyl ether and 1 M HCl. The phases were separated and the aqueous was extracted with diethyl ether (x3). The combined organic extracts were washed with 1 M HCl, sat. aq. sodium bicarbonate, water, and brine, and dried over anhydrous sodium sulfate. After filtration, the solvent was removed in vacuo to afford the amide product which was used in the next step without additional purification.

The reaction mixture was concentrated to dryness, diluted with methanol (0.1 M) and 6 M HCl (3 mL), and refluxed for 30 min. After cooling to room temperature, the methanol was removed in vacuo and the crude mixture was basified with 3 M NaOH aqueous solution and extracted with DCM (x5). The combined organic extracts were washed with brine and dried with anhydrous sodium sulfate, filtered, and concentrated in vacuo to afford the target as solid. Formation of the free base target compound was confirmed by HRMS (M+H)+ (Found: 228.1204 m/z; Calc'd: 228.1194 m/z) and 1H NMR (600 MHz, d4-MeOH) δ 6.94 (dd, J=9.0, 4.6 Hz, 1H), 6.89 (ddd, J=9.0, 8.0, 3.0 Hz, 1H), 6.76 (dd, J=9.4, 3.0 Hz, 1H), 4.92-4.70 (m, 2H), 4.38-4.16 (m, 2H), 3.02 (d, J=7.5 Hz, 2H), 3.05-2.99 (m, 2H), 2.16 (dt, J=9.0, 5.3 Hz, 1H), 1.31-1.22 (m, 1H), 1.18 (dt, J=8.5, 5.5 Hz, 1H), 1.04 (dt, J=9.0, 5.2 Hz, 1H).

Functional Assays for 5-HT2A, 5-HT2B, and 5-HT2C Receptors
To measure 5-HT2 receptor-mediated Gq activation via Gq/y1 dissociation as measured by Bioluminescence Resonance Energy Transfer (BRET) (McCorvy J D, Wacker D, Wang S, Agegnehu B, Liu J, Lansu K, Tribo AR, Olsen RHJ, Che T, Jin J, Roth BL. Structural determinants of 5-HT2B receptor activation and biased agonism. Nat Struct Mo/Biol. 2018; 25(9): 787-96), HEK293T cells were sub-cultured in Dulbecco's Modified Eagle Medium (DMEM) supplemented with 10% dialyzed fetal bovine serum (FBS) and were co-transfected in a 1:1:1:1 ratio with Rluc8-fused human Gaq (Gaq-Rluc8), a GFP2-fused to the C-terminus of human Gy1(Gy1-GFP2), human GI31, and 5-HT2 receptor using TransiT-2020. After at least 18-24 hours, transfected cells were plated in poly-lysine coated 96-well white clear bottom cell culture plates in DMEM containing 1% dialyzed FBS at a density of 25,000-40,000 cells in 200 μL per well and incubated overnight. The following day, medium was decanted, and cells were washed with 60 μL of drug buffer (1×HBSS, 20 mM HEPES, pH 7.4), then 60 μL of drug buffer was added per well. Cells were pre-incubated at in a humidified atmosphere at 37° C. before receiving drug stimulation. Drug stimulation utilized 30 μL addition of drug (3X) diluted in McCorvy buffer (1×HBSS, 20 mM HEPES, pH 7.4, supplemented with 0.3% BSA fatty acid free, 0.03% ascorbic acid) and plates were incubated at for 1 hour at 37° C. Substrate addition occurred 15 minutes before reading and utilized 10 μL of the Rluc substrate coelenterazine 400a for Gq dissociation BRET2 (Prolume/Nanolight, 5 μM final concentration). Plates were read for luminescence at 400 nm and fluorescent GFP2 emission at 510 nm at 1 second per well using a Mithras LB940 multimode microplate reader (e.g. one provided by Berthold). The BRET ratios of fluorescence/luminescence were calculated per well and were plotted as a function of drug concentration using Graphpad Prism 8 (Graphpad Software Inc., San Diego, CA). Data were normalized to % 5-HT stimulation and analyzed using nonlinear regression “log(agonist) vs. response” to yield Emax and EC50 parameter estimates. Results are shown in Table 5, where A=<10; B=10 to <100; C=100 to 1000 and D=>1000; +++=>80%; ++=50 to 80%; and +=<50%; NA=No Activity. Gq signaling bias is reported for compounds exhibiting primary signaling for 5-HT2C via Gq-coupled signaling mechanism when compared to signaling mechanisms taking place through B-arrestin. Hallucinogenic (“Hall”) or non-hallucinogenic (“N-Hall”) plastogenic effect is predicted for compounds based on the level 5-HT2A agonist efficacy.

Biological Studies
Head-Twitch Response (HTR) Experiments.
Dose-response studies. Dose-response studies for compounds of Formula I are performed in four consecutive steps:
(a). Formulation work. A suitable (non-toxic) vehicle is identified that can be used to dissolve the compound.
(b). Pilot dose-finding study. HTR-inducing drugs typically have biphasic bell-shaped (inverted U-shaped) dose-response functions, with ascending and descending phases. To quantify the potency of a drug in a HTR dose-response study, doses covering the entire extent of the ascending phase should be included, as well as at least one dose that falls on the descending phase. A pilot dose-finding study is performed to identify a set of doses that matches those requirements. For the pilot, male C57BL/6J mice are injected with a range of doses (typically 0.3-30 mg/kg) by the IP or SC route and then behaviors are recorded in a magnetometer chamber for up to 150 minutes.
(c). Dose-response study. Groups of male C57BL/6J mice with a magnet implant are injected with vehicle or 4-5 doses of the compound (n=5-7 mice/group) by the IP or SC route and then behaviors are recorded in a magnetometer chamber for at least 30 minutes.
(d). Repeated testing. Although potency can typically be quantified based on a single dose-response study, in some instances repeated testing may be necessary. For example, the doses selected for testing may not have been ideal to calculate the median effective dose (ED50 value). If necessary, a second or third dose-response study is performed.
Analysis: The following analyses are performed for dose-response studies: HTR counts are analyzed using a 1-way ANOVA followed by a post-hoc test (Dunnett's test).
The median effective dose (ED50 value) for the compounds (in mg/kg or moles/kg) will be calculated by nonlinear regression using a gaussian or sigmoidal model. The potencies of compounds and other reference compounds can also be compared statistically using an extra-sum-of-squares F-test.
HTR counts can be binned (e.g., blocks of 1, 2, 5, or 10 minutes) and analyzed using a 2-way ANOVA (drug×time) followed by a post-hoc test (Dunnett's test or Tukey's test). 5-HT2A Antagonist blockade studies. Four groups of male C57BL/6J mice with a magnet implant are pretreated SC with the selective 5-HT2A antagonist M100907 (vehicle, 0.001, 0.01, or 0.1 mg/kg). Twenty minutes later, all of the animals are injected IP or SC with one dose of the compound (n=5-7 mice/group) and then behaviors are recorded in a magnetometer chamber for 30 minutes. 5-HT1A Antagonist blockade studies. Four groups of male C57BL/6J mice (n=5-7 mice/group) with a magnet implant are pretreated SC with the selective 5-HT1A antagonist WAY-100635 (vehicle or 1 mg/kg). Twenty minutes later, the animals are injected IP or SC with vehicle or one dose of the compound and then behaviors are recorded in a magnetometer chamber for at least 30 minutes.
Extended time-course studies. Male C57BL/6J mice with a magnet implant are injected IP or SC with up to three different treatments (n=5-6 mice/group) and then behaviors are recorded in a magnetometer chamber for up to 5 hours (the exact assessment period used will depend on the duration-of-action of the Material being tested).
Brain penetration testing. These studies are used to test whether 5-HT2A ligands that do not induce the HTR are brain penetrant in mice. Male C57BL/6J mice with a magnet implant are pretreated IP or SC with vehicle or three doses of the 5-HT2A ligand (n=5-7 mice/group); 20 minutes later, all of the mice are injected IP with 1 mg/kg (±)-DOI HCl, and then behaviors are recorded in a magnetometer chamber for 20-30 minutes.
hERG Inhibition Studies.
All experiments are conducted manually using a HEKA EPC-10 amplifier at room temperature in the whole-cell mode of the patch-clamp technique. HEK293 cells stably expressing hKv11.1 (hERG) under G418 selection can be sourced from the University of Wisconsin, Madison. Cells are cultured in DMEM containing 10% fetal bovine serum, 2 mM glutamine, 1 mM sodium pyruvate, 100 U ml-1 streptomycin, and 500 mg ml-1 penicillin, 100 μg ml-1 G418. The cell line is not authenticated or tested for mycoplasma contamination. Before experiments, cells are grown to 60-80% confluency, lifted using TrypLE, and plated onto poly-1-lysine-coated coverslips. Patch pipettes are pulled from soda lime glass (micro-haematocrit tubes) and should exhibit resistances of 2-4 MO. For the external solution, normal sodium Ringer is used (160 mM NaCl, 4.5 mM KCl, 2 mM CaCl2, 1 mM MgCl2, 10 mM HEPES, pH 7.4 and 290-310 mOsm). The internal solution used is potassium fluoride with ATP (160 mM KF, 2 mM MgCl2, 10 mM EGTA, 10 mM HEPES, 4 mM NaATP, pH=7.2 and 300-320 mOsm). A two-step pulse (applied every 10 s) from −80 mV initially to 40 mV for 2 s and then to −60 mV for 4 s, is used to elicit hERG currents. The percentage reduction of tail current amplitude by the compounds of Formula I that are tested is determined and data are shown as mean±s.d. (n=3-4 per data point). For all experiments, solutions of the drugs are prepared fresh from 10 mM stocks in DMSO. The final DMSO concentration never exceeds 1%.
Serotonin and Opioid Receptor Functional Assays.
Functional assay screens at 5-HT and opioid receptors are performed in parallel using the same compound dilutions and 384-well-format high-throughput assay platforms. Assays are used to assess activity at all human isoforms of the receptors, except where noted for the mouse 5-HT2A receptor. Receptor constructs in pcDNA vectors are generated from the Presto-Tango GPCR library39 with minor modifications. All tested compounds of Formula I are serially diluted in drug buffer (HBSS, 20 mM HEPES, pH 7.4 supplemented with 0.1% bovine serum albumin and 0.01% ascorbic acid) and dispensed into 384-well assay plates using a FLIPR Tetra automated dispenser head (Molecular Devices). Every plate includes a positive control such as 5-HT (for all 5-HT receptors), DADLE (DOR), salvinorin A (KOR), and DAMGO (MOR).
For measurements of 5-HT2A 5-HT2B, and 5-HT2C Gq-mediated calcium flux function, HEK Flp-In 293, T-Rex stable cell lines (Invitrogen) are loaded with Fluo-4 dye for one hour, stimulated with compounds and read for baseline (0-10 s) and peak fold-over-basal fluorescence (5 min) at 25° C. on the FLIPR Tetra system. For measurement of 5-HT6 Gs and 5-HT7a functional assays, -mediated cAMP accumulation is detected using the split-luciferase GloSensor assay in HEKT cells measuring luminescence on a Microbeta Trilux (Perkin Elmer) with a 15 min drug incubation at 25° C. For 5-HT1A, 5-HT1B, 5-HT1F, MOR, KOR and DOR functional assays, Gi/o,—mediated cAMP inhibition is measured using the split-luciferase GloSensor assay in HEKT cells, conducted similarly to that above, but in combination with either 0.3 μM isoproterenol (5-HT1A, 5-HT1B, 5-HT1F) or 1 μM forskolin (MOR, KOR and DOR) to stimulate endogenous cAMP accumulation. For measurement of 5-HT1D, 5-HT1E, 5-HT4, and 5-HT5A functional assays, 1-arrestin2 recruitment is measured by the Tango assay using HTLA cells expressing tobacco etch virus (TEV) fused-β-arrestin2, as described previously with minor modifications. Cell lines are not authenticated, but they are purchased mycoplasma-free and tested for mycoplasma contamination. Data for all assays are plotted and nonlinear regression is performed using “log(agonist) vs. response” in GraphPad Prism to yield estimates of the efficacy (Emax and half-maximal effective concentration (ECSO)).
Pharmacokinetic Studies.
Male and female C57/BL6J mice (12 weeks old) are administered a compound of Formula I via i.p. injection at doses of either 50 mg kg-1, 10 mg kg-1 or 1 mg kg-1. Mice are euthanized 15 min or 3 h after injection by cervical dislocation. Two males and two females are used per dose and time point. Brain and liver are collected, flash-frozen in liquid nitrogen, and stored at −80° C. until metabolomic processing. Whole brain and liver sections are lyophilized overnight to complete dryness, then homogenized with 3.2 mm diameter stainless-steel beads using a GenoGrinder for 50 s at 1,500 rpm. Ground tissue is then extracted using 225 μl cold methanol, 190 μl water, 750 μl methyl tert-butyl ether (MTBE). Seven method blanks and seven quality-control samples (pooled human serum, BiolVT) are extracted at the same time as the samples. The nonpolar fraction of MTBE is dried under vacuum and reconstituted in 60 μl of 90:10 (v/v) methanol: toluene containing 1-cyclohexyldodecanoic acid urea as an internal standard. Samples are then vortexed, sonicated and centrifuged before analysis.
For analysis of the tested compound in liver and brain, samples are randomized before injection with method blanks and quality-control samples are analyzed between every ten study samples. A six-point calibration curve is analyzed after column equilibration using blank injections, and then after all study samples. Blanks are injected after the calibration curve to ensure no that none of the tested compound is retained on the column and carried over to samples. Reconstituted sample (5 μl) is injected onto a Waters Acquity UPLC CSH C18 column (100 mm×2.1 mm, 1.7 μm particle size) with an Acquity UPLC CSH C18 VanGuard precolumn (Waters) using a Vanquish UHPLC coupled to a TSQ Altis triple quadrupole mass spectrometer (Thermo Fisher Scientific). Mobile phase A consists of 60:40 v/v acetonitrile/water with 10 mM ammonium formate and 0.1% formic acid. Mobile phase B consists of 90:10 v/v isopropanol/acetonitrile with 10 mM ammonium formate and 0.1% formic acid. Gradients are run from 0-2 min at 15% B; 2-2.5 min 30% B; 2.5-4.5 min 48% B; 4.5-7.3 min 99% B; 7.3-10 min 15% B. The flow rate is 0.600 ml/min and the column is heated to 65° C. Mass spectrometer conditions are optimized for the target compound by direct infusion. Selected reaction monitoring is performed for the top five ions, with collision energy, source fragmentation, and radiofrequency optimized for the test compound. Data are processed with TraceFinder 4.1 (Thermo Fisher Scientific). Organ weights are recorded. The concentration in the brain is calculated using the experimentally determined number of moles of the target compound in the whole organ divided by the weight of the organ.
5-HT Receptor Functional Assays.
Various assays for measuring serotonin receptor activation are known to those of skill in the art, including those methods described in Olsen et al., Nat. Chem. Biol., 2020 August; 16(8):841-49, incorporated herein by reference in its entirety for all purposes. The assays described therein may be utilized to measure the functional activity of any of the serotonin receptor subtypes described herein, including 5-HT1A, 5-HT2A, 5-HT2B, and 5-HT2C. In certain embodiments, serotonin (5-hydroxytryptamine) is used as the reference compound.
Cell Culture
HEK293T cells are maintained, passaged, and transfected in DMEM medium containing 10% FBS, 100 Units/mL penicillin, and 100 μg/mL streptomycin (Gibco-ThermoFisher, Waltham, MA) in a humidified atmosphere at 37° C. and 5% CO2. After transfection, cells are plated in DMEM containing 1% dialyzed FBS, 100 Units/mL penicillin, and 100 μg/mL streptomycin for BRET2, calcium, and GloSensor assays.
BRET2 Assays
Cells are plated either in six-well dishes at a density of 700,000-800,000 cells/well, or 10-cm dishes at 7-8 million cells/dish. Cells are transfected 2-4 hours later, using a 1:1:1:1 DNA ratio of receptor:Ga-RLuc8:Gs:Gy-GFP2 (100 ng/construct for six-well dishes, 750 ng/construct for 10-cm dishes), except for the Gy-GFP2 screen, where an ethanol co-precipitated mixture of Gβ1-4—is used at twice its normal ratio (1:1:2:1). Transit 2020 (Mirus Biosciences, Madison, WI) is used to complex the DNA at a ratio of 3 μL Transit/μg DNA, in OptiMEM (Gibco-ThermoFisher, Waltham, MA) at a concentration of 10 ng DNA/μL OptiMEM. The next day, cells are harvested from the plate using Versene (0.1 M PBS+0.5 mM EDTA, pH 7.4), and plated in poly-D-lysine-coated white, clear bottom 96-well assay plates (Greiner Bio-One, Monroe, NC) at a density of 30,000-50,000 cells/well.
One day after plating in 96-well assay plates, white backings (Perkin Elmer, Waltham, MA) are applied to the plate bottoms, and growth medium is carefully aspirated and replaced immediately with 60 μL of assay buffer (1x HBSS+20 mM HEPES, pH 7.4), followed by a 10 μL addition of freshly prepared 50 μM coelenterazine 400a (Nanolight Technologies, Pinetop, AZ). After a five-minute equilibration period, cells are treated with 30 μL of drug for an additional 5 minutes. Plates are then read in an LB940 Mithras plate reader (Berthold Technologies, Oak Ridge, TN) with 395 nm (RLuc8-coelenterazine 400a) and 510 nm (GFP2) emission filters, at 1 second/well integration times. Plates are read serially six times, and measurements from the sixth read are used in all analyses. BRET2 ratios are computed as the ratio of the GFP2 emission to RLuc8 emission.
Calcium Mobilization Assays
Cells are plated in 10-cm plates as described in the BRET2 protocol and co-transfected with receptor (1 μg) and Ga-subunit (1 μg) cDNA. The next day, cells are plated at 15,000 cells/well in poly-D-lysine coated black, clear bottom 384-well plates (Greiner Bio-One, Monroe, NC). The following day, growth medium are aspirated and replaced with 20 μL assay buffer containing 1× Fluo-4 Direct Calcium Dye (ThermoFisher Scientific, Waltham, MA) and incubated for 60 minutes at 37° C. (no CO2). Plates are brought to RT for 10 minutes in the dark before being loaded into a FLIPR Tetra® liquid-handling robot and plate reader (Molecular Devices, San Jose, CA). Baseline fluorescence measurements are taken for 10 seconds followed by robotic drug addition (10 μL) and a 60-second measurement (1 measurement/second). For antagonist assays, cells are first treated with antagonist and kept in the dark at room temperature for ten minutes before agonist addition by the FLIPR Tetra® robot. Maximal response during this time is used to calculate amplitude of the calcium transients. Measurements are analyzed as percentage of maximum signal amplitude for the construct.
Glosensor cAMP Assays
Cells are plated in 10-cm plates as previously described. Cells are transfected with plasmids encoding cDNA for the Glosensor reporter (Promega, Madison, WI), receptor, and Ga-subunit at a ratio of 2:1:1 (2 μg: 1 μg: 1 μg). The next day, cells are plated in black, clear-bottom, 384-well white plates. After aspiration of the medium on the day of the assay, cells are incubated for 60 minutes at 37° C. with 20 μL of 5 mM luciferin substrate (GoldBio, St. Louis, MO) freshly prepared in assay buffer. For Gas activity, 10 μL of drugs are added using the FLIPR Tetra@liquid-handling robot and read after 15 minutes in a Spectramax luminescence plate reader (Molecular Devices, San Jose, CA) with a 0.5 second signal integration time. For Gai activity, 10 μL of drugs are added for a 15-minute incubation period. Subsequently, 10 μL of isoproterenol (final concentration of 200 nM) are added and incubated for an additional 15-minute period before reading.

William's E Medium, human recombinant insulin, HEPES, DPBS and GlutaMAX are purchased from Gibco. Isotonic Percoll is purchased from Solarbio. Fetal bovine serum is purchased from Avantor. Dexamethasone is purchased from Solarbio. 96-well plates are purchased from Corning.
Experimental Procedure: Preparation of Working Solutions—Prepare 10 mM stock solutions of test compound(s) and positive controls in appropriate solvent (DMSO). In 96-well plates, diluted to 100 μM by combining 198 μL of 50% acetonitrile/50% water and 2 μL of 10 mM positive controls. Preparation of Hepatocytes—Place incubation medium (William's E Medium supplemented with GlutaMAX) and hepatocyte thawing medium in a 37° C. water bath, and allow warming for at least 15 minutes prior to use. Remove a vial of cryopreserved hepatocytes from storage, ensuring that vials remain at cryogenic temperatures until thawing process ensues. Thaw the cells by placing the vial in a 37° C. water bath and gently shaking the vials for 2 minutes. After thawing is completed, spray vial with 70% ethanol, transfer the vial to a biosafety cabinet. Use wide-bore pipette tip to transfer hepatocytes into 50 mL conical tube containing thawing medium. Place the 50 mL conical tube into a centrifuge and spin at 80 g for 8 minutes. Upon completion of spin, aspirate thawing medium and resuspend hepatocytes in enough incubation medium to yield ˜1.5×106 cells/mL. Using an AO/PI staining solution, count cells and determine the viable cell density. Cells with poor viability (<75% viability) are not acceptable for use. Dilute cells with incubation medium to a working cell density of 0.5×106 viable cells/mL. Compound Incubation—Pipette 198 μL of hepatocytes into each well of a 96-well non-coated plate. Place the plate in the incubator on an orbital shaker to allow the hepatocytes to warm for 10 minutes. Pipette 2 μL of the 100 μM test compound(s) or positive control into respective wells of the 96-well plate to start the reaction. The final test concentration is 1 μM. Return the plate to the incubator and place on an orbital shaker. The reaction for each compound will be performed in duplicate. Procedure for Stability Determination—Remove 25 μL aliquots of reaction mixture at time points of 0, 15, 30, 60, 90 and 120 minutes. The aliquots are then mixed with 6 volumes (150 μL) of acetonitrile containing internal standards (IS: 100 nM tolbutamide, 200 nM labetalol, 100 nM ketoprofen, 200 nM imipramine and 200 nM diclofenac) to terminate the reaction. Centrifuge the plate for 45 minutes at 3,220 g. Aliquots of 100 μL of the supernatants will be mixed with 100 μL ultrapure water and used for LC/MS/MS analysis.
Data Analysis: All calculations are carried out using Microsoft Excel. Peak areas are determined from extracted ion chromatograms. Determine the in vitro half-life (t1/2) of parent compound by regression analysis of the percent parent disappearance vs. time curve. The in vitro half-life (in vitro t1/2) is determined from the slope value:
in vitro t1/2=−0.693/k
Conversion of the in vitro t1/2 (in mi) into the in vitro intrinsic clearance (in vitro CLint, in μL/min/106 cells) is done using the following equation (mean of duplicate determinations):
in vitro CLint=kV/N
Where V=incubation volume (0.2 mL); N=number of hepatocytes per well (0.1×106 cells).

Remove the vial of hepatocytes from storage, ensuring that vials remain at cryogenic temperatures until thawing process ensues. As quickly as possible, thaw the cells by placing the vial in a 37° C. water bath and gently shaking the vials. Vials should remain in water bath until all ice crystals have dissolved and are no longer visible. Open the vial and pour the contents into the conical tube containing 50 mL thawing medium, then centrifuge at 80 g for 6 minutes. Upon completion of spin, aspirate thawing medium and resuspend hepatocytes in enough incubation medium to yield ˜1.5×106 cells/mL. Using Cellometer® Vision, count cells and determine the viable cell density. Cells with poor viability (<75% viability) are not acceptable for use. Dilute cells with incubation medium to a working cell density of 1×106 viable cells/mL. For the 0-min sample, aliquots (199 μL) of hepatocytes suspension will be transferred into a 24-well plate, 600 μL of acetonitrile containing 0.1% formic acid will be added into corresponding wells, and then 1 μL of test article working solution (2 mM) will be added. For the 120 min, 240 min and blank (240 min) samples, the 120 min, 240 min samples are started with the addition of 1 μL of 2 mM compound solution into 24-well plate contain of 199 μL of hepatocytes suspension. and the blank samples are started with the addition of 1 μL acetonitrile/DMSO solution into 199 μL of hepatocytes suspension. The incubations will be carried out in an incubator (37° C., 5% CO2) on an orbital shaker at ˜500 rpm. The reaction will be quenched by adding 600 μL of acetonitrile containing 0.1% formic acid into respective well at the corresponding time points. The supernatant is used for UHPLC-UV-MS/MS analysis (If needed, the supernatants (600 μL) will be transferred and placed in the evaporator under steady stream of nitrogen at room temperature until dry. The dried residues will be reconstituted with 100 μL of diluents (acetonitrile: water (v/v)=1:4). If acetonitrile: water (v/v)=1:4 cannot reconstitute the sample well, other diluents will be used. Then samples will be centrifuged at 16,000×g for 30 minutes. The supernatant will be transferred and analyzed by UHPLC-UV-MS/MS. The control compound verapamil is included in the experiment with sample incubation method. The time points are 0 min and 240 min. The remaining percentage of verapamil will be used to monitor the hepatocytes activity. Noted that the incubation time should be compound dependent, guided by hepatocytes stability, target % parent remaining ˜50% compared with 0 min sample.
Instrumentation—UHPLC-MS/MS analysis is conducted using a Dionex UltiMate 3000 UHPLC system/Vanquish UHPLC system (Thermo Scientific, USA). Thermo Scientific Q Exactive/Orbitrap Exploris 120/240 (Thermo Scientific, USA) fitted with a HESI probe. Mass Spectrometry Analysis—All analyses are carried out with a high-resolution mass spectrometric instrument. Both data from positive and negative ionization mode will be collected. Compound dependent parameters will be optimized by test article. Parallel reaction monitoring (PRM) will be used to acquire MS2 spectra. UHPLC-UV was used to collect the UV peak area of parent drug and metabolites (if the product content was too low, there might be no UV signal).
Data Analysis: A common method in metabolite identification includes the production of metabolites by in vitro or in vivo experiments, collection of samples at different time points and analysis of the samples by using full-scan MS. The metabolites are identified by comparison of the ion chromatograms between a blank and the other samples under consideration of the expected metabolites according to predicted gains and losses in molecular mass of the parent drug. Once molecular ions for possible metabolites are detected, they can be subjected to analysis by MS/MS and the product ion MS/MS spectra of the parent compound can subsequently compared with the corresponding fragmentation pattern of metabolite structures. The specific fragment ion that showed a shift in its m/z helps to identify the site of the modification of the molecule. Data will be acquired and processed using Xcalibur software (Thermo Fisher Scientific) and Compound Discoverer (Thermo Fisher Scientific). The relative peak areas are determined from extracted ion chromatograms of hepatocytes samples at 240 min.
Data Presentation: A Microsoft PowerPoint report will be prepared, which includes a summary of the material and bioanalytical method; metabolite screening results; the MS/MS spectra of parent drug and potential metabolites; and the MS/MS spectra analysis of parent drug and potential metabolites.
