[0002] Government Rights in This Invention
[0003] This invention was made with government support under Grant No. R01-12970 awarded by the National Institute on Drug Abuse (NIDA) of the National Institutes of Health. The government has certain rights in this invention.
[0004] field
[0005] The present disclosure relates to phenethylamine compounds (including vinylogous phenethylamines) useful as monoamine neurotransmitter releasers, methods of using phenethylamine compounds in therapeutic or therapeutic regimens, and pharmaceutical compositions containing such compounds.
[0006] Specifically, the present disclosure relates to compounds that are monoamine neurotransmitter releasers capable of functioning as dual dopamine and serotonin (DA / 5HT) releasers or dopamine releasers and serotonin uptake inhibitors. The present disclosure also relates to pharmaceutical compositions comprising one or more dual DA / 5HT releasers or dopamine releasers and serotonin uptake inhibitors, which may also comprise one or more additional therapeutic agents. The present disclosure also relates to methods for treating various diseases, conditions, and / or disorders that respond to administration of dual DA / 5HT releasers or dopamine releasers and serotonin uptake inhibitors, such as substance abuse, depression, and other similar conditions or neurological diseases.
[0007] Description of related art
[0008] The plasma membrane biogenic amine transporter (BAT) regulates neuronal signaling in the central nervous system by transporting previously released monoamine neurotransmitters—dopamine, norepinephrine, and 5-hydroxytryptamine (DA, NE, and 5-HT, transported via DAT (dopamine transporter), NET (norepinephrine transporter), and SERT (5-hydroxytryptamine transporter), respectively—from synapses back to the neuronal cytoplasm. Ligands that interact with BAT are divided into two major categories: reuptake inhibitors and substrate-type releasers. Both types of ligands increase extracellular neurotransmitter concentrations, but act via different mechanisms. Reuptake inhibitors bind to transporters and block transporter-mediated reuptake of neurotransmitters. Substrate-type releasers bind to substrate sites on transporters, are transported to the interior of neurons, and promote neurotransmitter efflux through carrier-mediated exchange. Disturbances in BAT function play an important role in the pathophysiology of many neurological diseases such as depression, anxiety, Parkinson's disease, schizophrenia, and psychostimulant addiction.
[0009] Psychostimulants, such as cocaine and methamphetamine, are addictive drugs that target BAT in the central and peripheral nervous systems to cause various harmful physiological effects in humans. A potential strategy for treating psychostimulant addiction is known as agonist replacement therapy, whereby patients are administered less potent and less addictive stimulant drugs. BAT releasers represent a class of compounds that are evaluated as potential agonist drugs.
[0010] Several studies have demonstrated the ability of S(+)-amphetamine to
[0011]
[0012] It has high selectivity for releasing DA relative to 5-HT, acting as an agonist therapy for stimulant dependence.
[0013] Chronic treatment with S(+)-amphetamine in rhesus monkeys resulted in a selective, dose-dependent reduction in cocaine self-administration compared to food-maintained responding using progressive-ratio, choice, and two-stage regimens. In a double-blind, placebo-controlled clinical trial, treatment with S(+)-amphetamine resulted in a reduction in cocaine use, consistent with other clinical trials testing agonist treatments. However, a significant limitation of the use of S(+)-amphetamine as a drug is its potential for abuse due to activation of mesolimbic dopamine neurons.
[0014] Previous evidence suggests that the loss of both DA and 5-HT is associated with withdrawal symptoms, and that an increase in extracellular 5-HT can counteract the stimulant and reinforcing effects of DA (a dual-deficit model of stimulant addiction). One potential advantage of using dual DA / 5-HT releasers as agonist drugs is their ability to provide the necessary stimulant-like properties (i.e., DA release) for therapeutic efficacy while reducing abuse liability (5-HT release). Thus, multiple lines of evidence suggest that elevated 5-HT can reduce drug-seeking behavior. In vivo studies in rats have revealed that 5-HT release reduces the stimulant effects of amphetamine-type drugs, and for example, fenfluramine (a 5-HT releaser) dose-dependently attenuates cue-reinstated cocaine-seeking behavior. The reduction in drug-seeking behavior observed in rats translates to humans, as fenfluramine significantly reduces cocaine craving in abstinent cocaine-dependent patients. Furthermore, in preliminary clinical trials, co-administration of the anorectic phentermine (DA releaser) and fenfluramine (Fen-Phen) has shown promise in treating cocaine and alcohol dependence, thus supporting the use of dual DA / 5-HT releasers as therapeutic agents. However, Fen-Phen and other similar neurotransmitter releasers also have activities that are often associated with adverse effects.
[0015] There is a need in the art for neurotransmitter releasers and / or uptake inhibitors that are useful in the treatment of substance abuse and provide other therapeutic effects with little or no activity at off-target sites that are typically associated with the adverse effects of known compounds that are effective as neurotransmitter releasers and / or uptake inhibitors.

The compounds of the present disclosure are useful in methods for treating or delaying the progression of diseases, conditions and / or disorders that are alleviated by inhibiting monoamine reuptake in a patient or by selectively binding to one or more monoamine transporters.
[0065] As used herein, the terms "treat," "treatment," or "treating" refer to any method used to partially or completely alleviate, ameliorate, alleviate, inhibit, prevent, delay the onset of, reduce the severity of, and / or reduce the incidence of one or more symptoms or characteristics of a particular disease, disorder, and / or condition.
[0066] As used herein, the term "subject" refers to a human or any non-human animal (e.g., a mouse, rat, rabbit, dog, cat, cow, pig, sheep, horse, or primate). In many embodiments, the subject is a human. The subject can be a patient, which refers to a human being presented to a medical provider for diagnosis or treatment of a disease, condition, and / or disorder. The terms "subject" and "individual" or "patient" are used interchangeably herein. A subject may be suffering from or afflicted with a disease, condition, or disorder, but may or may not display symptoms of the disease, condition, or disorder.
[0067] The present disclosure specifically provides methods of treating diseases, conditions, or disorders that are responsive to monoamine transporter uptake inhibitors and / or monoamine transporter substrate-releasing agents, comprising administering to a subject in need thereof a therapeutically effective amount of a phenethylamine compound according to Formula I or Formula II, or a pharmaceutically acceptable ester, amide, salt, solvate, prodrug, or isomer thereof.
[0068] The compounds of the present disclosure avoid the effects of the previously known monoamine transporter uptake inhibitors and / or monoamine transporter substrate-releasing agents on the 5HT receptors, particularly on the 5HT 2b Receptors and 5HT 2a This lack of substantial activity at "off-target" sites allows for the reduction or attenuation of adverse reactions from administering the monoamine transporter uptake inhibitors and / or monoamine transporter substrate-releasing agents disclosed herein to a subject in need of treatment for a disease, condition, and / or disorder that can be modulated by activity at a biogenic amine transporter.
[0069] Diseases, conditions and / or disorders to be treated with the phenylethylamines of the present disclosure may include obesity, sleep disorders, neurological diseases, depression, anxiety, ADHD, and substance use disorders (including stimulant addiction such as cocaine addiction and methamphetamine addiction, and alcohol addiction). In embodiments, the condition or disorder is stimulant addiction, more specifically, psychostimulant addiction.
[0070] In one aspect of the present disclosure, there is provided a method of treating psychostimulant addiction, the method comprising administering to a subject in need thereof a therapeutically effective amount of a compound according to the structure of Formula I:
[0071]

[0076] The phenylethylamine compounds disclosed herein as active agents may contain chiral centers that may be in the (R) configuration or the (S) configuration, or may contain mixtures thereof. Therefore, the present disclosure also includes stereoisomers of the compounds described herein, where applicable, individually or mixed in any proportion. Stereoisomers may include, but are not limited to, enantiomers, diastereomers, racemic mixtures, and combinations thereof. Such stereoisomers can be prepared and separated using conventional techniques by reacting enantiomeric starting materials, or by separating isomers of the compounds disclosed herein. Isomers may include geometric isomers. Examples of geometric isomers include, but are not limited to, cis-isomers or trans-isomers that span a double bond. Other isomers are contemplated in the compounds of the present disclosure. Isomers may be used in pure form or in admixture with other isomers of the compounds described herein.
[0077] Various methods for preparing optically active forms and determining activity are known in the art. Such methods include the standard assays described herein and other similar assays well known in the art. Examples of methods that can be used to obtain optical isomers of compounds according to the present disclosure include the following:
[0078] i) physical separation of crystals, whereby macroscopic crystals of the individual enantiomers are manually separated. This technique can be used specifically when crystals of the individual enantiomers are present (i.e., the material is a conglomerate) and the crystals are visually distinct;
[0079] ii) simultaneous crystallization, whereby the individual enantiomers are crystallized separately from a solution of the racemate, which is only possible if the racemate is an aggregate in the solid state;
[0080] iii) enzymatic resolution, whereby racemates are partially or completely separated by virtue of the different rates for the reaction of the enantiomers with an enzyme;
[0081] iv) enzymatic asymmetric synthesis, a synthetic technique whereby at least one step of the synthesis uses an enzymatic reaction to obtain an enantiomerically pure synthetic precursor or an enantiomerically enriched synthetic precursor of the desired enantiomer;
[0082] v) chemical asymmetric synthesis, whereby the desired enantiomer is synthesized from achiral precursors under conditions that produce asymmetry (i.e., chirality) in the product, which can be achieved using chiral catalysts or chiral auxiliaries;
[0083] vi) diastereoisomer separation, whereby the racemic compound is reacted with an enantiomerically pure reagent (chiral auxiliary) to convert the individual enantiomers into diastereomers. The resulting diastereomers are then separated by chromatography or crystallization on the basis of their now more distinct structural differences, and the chiral auxiliary is later removed to obtain the desired enantiomer;
[0084] vii) primary and secondary asymmetric transformations whereby diastereomers from the racemate equilibrate to give rise to a preponderance in solution of the diastereomer from the desired enantiomer, or whereby preferential crystallization of the diastereomer from the desired enantiomer disturbs the equilibrium so that ultimately, in principle, all of the material is converted to the crystalline diastereomer from the desired enantiomer. The desired enantiomer is then liberated from the diastereomers;
[0085] viii) kinetic resolution, including the partial or complete resolution (or further resolution of partially resolved compounds) of racemates by means of unequal reaction rates of enantiomers with chiral, non-racemic reagents or catalysts under kinetic conditions;
[0086] ix) enantiospecific synthesis from non-racemic precursors, whereby the desired enantiomer is obtained from achiral starting materials and wherein the stereochemical integrity is not compromised or only minimally compromised during the synthesis;
[0087] x) Chiral liquid chromatography, whereby the enantiomers of the racemate are separated in a liquid mobile phase by virtue of their different interactions with the stationary phase. The stationary phase may be made of a chiral material, or the mobile phase may contain additional chiral materials to induce different interactions;
[0088] xi) chiral gas chromatography, whereby the racemate is volatilized and the enantiomers are separated by means of their different interactions in the gaseous mobile phase with a column containing a stationary non-racemic chiral adsorbent phase;
[0089] xii) extraction using a chiral solvent, whereby enantiomers are separated by virtue of preferential solubility of one enantiomer in a particular chiral solvent; and
[0090] xiii) Transport across a chiral membrane, whereby the racemate is placed in contact with a membrane barrier. The barrier typically separates two miscible fluids, one containing the racemate, and a driving force, such as a concentration or pressure difference, results in preferential transport across the membrane barrier. The separation occurs due to the non-racemic chiral nature of the membrane, which allows only one enantiomer of the racemate to pass.
[0091] Optionally, the compound can be provided in an enantiomerically enriched composition, e.g., a mixture of enantiomers in which one enantiomer is present in excess, particularly to the extent of 60% or more, 75% or more, 90% or more, 95% or more, or 98% or more, including 100%.
[0092] The compounds of the present disclosure may be used per se or in the form of pharmaceutically acceptable esters, amides, salts, solvates, prodrugs, or isomers. For example, the compounds may be provided as pharmaceutically acceptable salts. If used, salts of pharmaceutical compounds should be both pharmacologically acceptable and pharmaceutically acceptable, but non-pharmaceutically acceptable salts may be conveniently used to prepare the free active compound or its pharmaceutically acceptable salt and are not excluded from the scope of the present disclosure.
[0093] Such pharmacologically acceptable salts and pharmaceutically acceptable salts can be prepared by the reaction of drugs with organic or inorganic acids, using the standard methods described in detail in the literature. Examples of pharmaceutically acceptable salts of compounds useful according to the present disclosure include acid addition salts. However, salts of non-pharmaceutically acceptable acids can be useful, for example, in the preparation and purification of compounds.

In practice, this will vary widely depending on the specific compound, its activity, the severity of the condition to be treated, the patient population, the stability of the formulation, etc.
[0110] The treatment methods according to the present disclosure generally comprise administering a therapeutically effective amount of a compound of Formula I or a compound of Formula II, optionally in a pharmaceutical composition comprising one or more pharmaceutically acceptable carriers, wherein the therapeutically effective amount is preferably sufficient to achieve the release of dopamine and serotonin or to achieve the release of dopamine and the inhibition of the uptake of serotonin. The therapeutically effective amount is also preferably sufficient to provide the patient with relief of the symptoms of the disease, condition, or disorder for which the patient is being treated.

Example
[0113] The present disclosure also encompasses methods of preparing compounds having structures as disclosed herein. In order to obtain compounds that are effective as dual DA and 5-HT releasers, available information on 1-naphthyl-2-aminopropane (PAL-287 (PAL, Phenyl Amine Library)) as a comparative compound was evaluated. PAL-287,
[0114]
[0115] Release of radiolabeled neurotransmitters from DAT, SERT, and NET, where EC 50The values were 12.6 nM, 3.4 nM, and 11.1 nM, respectively (Table 1). In vivo microdialysis experiments in rats confirmed the in vitro data by showing that PAL-287 (1-3 mg / kg Lv.) increased extracellular DA and 5-HT in the frontal cortex, with a greater effect on 5-HT (464% increase compared to 133% increase). Furthermore, in rats, PAL-287 caused significantly less locomotor stimulation than S(+)-amphetamine, which is 71-fold more potent at releasing DA than 5-HT; importantly, high doses of PAL-287 did not cause cortical 5-HT depletion. In rhesus monkeys trained to self-administer cocaine, PAL-287 produced a dose-dependent decrease in cocaine self-administration and significantly reduced cocaine-maintained responding relative to food at 1.0 mg / kg / h. In general, data collected with the non-amphetamine analog PAL-287 support the hypothesis that dual DA / 5-HT releasers possess the therapeutic effects of amphetamine-type releasers while being minimally potentiating.
[0116] Therefore, a series of phenylethylamines were synthesized and their transporter activities were evaluated. Four groups of phenylethylamine analogs were synthesized, as shown below.
[0117]
[0118] The I group is made up of racemic alkynyl isostere (isostere) 4 and two chiral isosteres S-4 and R-4. The II group is made up of racemic and chiral (E)-alkenyl isostere (6, S-6, R-6), and the III group is made up of corresponding (Z)-alkenyl isostere (8, S-8, R-8). The analogs (10, 11) of the IV group have a less carbon between the phenyl ring and the amine group. All analogs are synthesized in three steps or four steps by commercially available materials. Scheme 1 shows the synthesis of (S)-stereoisomers from Group I-Group III.
[0119]
[0120] To synthesize Group I alkynes S-4, commercially available alcohols R-3 are converted to tosylates, which undergo configurational inversion to azide displacement, which is reduced under Staudinger conditions to provide S-4. The same commercially available starting alcohols R-3 are selectively reduced with lithium aluminum hydride (LAH) or Lindlar catalyst to provide the corresponding (E)-olefins or (Z)-olefins, R-5 and R-7, respectively. These olefins are then converted to amines S-6 and S-8, respectively, using the same three-step tosylation / azide formation / Staudinger reduction steps. The (R) stereoisomers and racemates of Groups I-III are synthesized using the same pathway starting with the corresponding commercially available (S)-alcohols and racemic alcohols, respectively.
[0121] Scheme 2 shows the synthesis of Group IV vinylogous phenethylamines (10, 11) from commercially available alcohol 9 using the same route as the compounds synthesized in Scheme 1, except that mesylation was performed instead of tosylation due to stability issues.
[0122]
[0123] Scheme 2: Synthesis of Group IV Analogs
[0124] According to the protocol developed by Rothman and collaborators (Rothman, et al., Eur. J. Pharmacol. 2002, 447 (1), 51), BAT activity was measured using synaptosomes prepared from rat brain homogenate. Compounds were first screened in uptake inhibition and release assays to determine the exact mode of drug action. Compounds that were active in both assays were releasers, while compounds that were only active in the uptake inhibition assay were uptake inhibitors. The active compounds were then fully characterized by running 8-point concentration response curves in an assay corresponding to their mechanism of action. Substrate reversal experiments were performed to verify substrate activity. As previously described, analogs were tested for their activity at 5-hydroxytryptamine-2 receptor subtypes (5-HT) using an in vitro calcium mobilization assay in transfected HEK293 cells. 2A , 5-HT 2B , 5-HT 2C These receptors are relevant to the pharmacology of drugs of abuse because 5-HT 2A Agonists are considered hallucinogenic, and 5-HT agonists have been associated with valvular heart disease and pulmonary hypertension; activity at these receptors would be considered off-target. 2C Agonists of α-glucose agonist may be beneficial as potential pharmacotherapy for drug abuse and appetite suppression.
[0125] Table 1 shows the transporter data for the analogs. All compounds were active as DAT and NET releasers, with varying potencies, and all except two compounds, 10 and 11, were active as SERT releasers. At DAT, the Group I alkynes had similar potencies, with S-4 being the most potent, with an EC of 0. 50 The alkynes also had similar potency at SERT, with R-4 being the most potent, with an EC 50 The value was 288 nM. At NET, alkyne R-4 was the most effective (EC 50 =496 nM), and 4 was the least potent (EC 50 =2980 nM). Group II (E)-olefins were effective at all three transporters, EC 50 The values were less than 540 nM. At DAT, Group II (E)-olefins had similar potency, with R-6 being the least potent (EC 50 =540 nM), and S-6 was the most effective, EC 50 The value is 206nM.
[0126] At SERT and NET, S-6 was the most active compound in the group, with EC 50 The values were 40 nM and 138 nM, respectively. At DAT, Group III (Z)-olefins were less than 1500 nM, with S-8 being the most potent at 304 nM. At SERT, analogs 8 and S-8 had similar potency, with 8 being slightly more potent (EC 50 =646 nM). At NET, S-8 was the most potent analog, with an EC 50 The value was 170 nM. Group IV analogs were inactive at SERT and were relatively weak releasers at DAT, with 10 being the most potent (EC 50 =666 nM). However, both analogs had similar potency at NET (EC 50 ≈300nM).

[0130] In Table 1, a:EC 50 Values were determined as described below, and each value is the mean ± SD (n = 3); b: Calcium mobilization EC 50Values were determined as described below; c: Data from Rothman, RB; Blough, BE; Baumann, MH Trends Pharmacol. Sci. 2006, 27(12), 612; IA = inactive at 10 μM.
[0131] From a structure-activity perspective, all compounds are substrates for the transporter, suggesting that the transporter can transport larger structures than previously thought. With the exception of Group IV, all compounds are dual DA / 5-HT releasers, but with varying degrees of transporter selectivity. Group I alkynes do not exhibit great selectivity for releasing 5-HT compared to DA, as racemic analogs 4 and R-4 are only 2.6-fold and 2.3-fold more potent at DAT, respectively. S-4 is essentially equivalent at DAT and SERT. Group II alkenes are all more selective at SERT relative to DAT, with 5-fold greater potency at SERT. This group is interesting because the activities at the transporter are very similar, indicating that there is no difference between the chiral isomers R-6 and S-6 and the racemate 6. Group III (Z)-alkenes are similar to Group I-alkynes in that the analogs do not show great SERT / DAT selectivity. Racemic analogs 8 and R-8 have similar potency in releasing 5-HT relative to DA (1.4-fold and 1.2-fold, respectively), whereas 5-8 is slightly more potent in releasing DA relative to 5-HT (2.2-fold). Removal of the carbon between the olefin and the amine (Group IV) results in analogs that are selective at DAT and NET. These compounds are inactive at SERT, indicating that they cannot bind to the transport site; this activity profile suggests that the compounds may be weak agonists.
[0132] In some studies, NE release has been found to be almost parallel to DA release, with slightly higher potency. Although most vinylogous analogs follow the DA / NE release trend, several compounds show selectivity for either DAT or NET. Group I racemic alkyne 4 is 3 times more effective in releasing DA than NE, EC 50 The values were 997 nM and 2980 nM, respectively. Analog S-4 followed the typical trend at DAT and NET, with EC 50 values were 660 nM and 496 nM, respectively, whereas for analog R-4, the activities at DAT and NET were reversed, with EC 50 The values were 443 nM and 784 nM, respectively. All group II (E)-olefins and two group III (Z)-olefins followed the typical trend; however, group III (Z)-olefin R-8 showed a 6.7-fold selectivity for releasing NE relative to releasing DA, EC 50The values were 211 nM and 1416 nM, respectively. Two analogs of Group IV, 10 and 11, were more potent at NET than at DAT, but had different selectivities (2.2-fold and 3.7-fold, respectively).
[0133] Compared with the other three groups, group II (E)-olefins were the most active compounds. The most effective analogues at DAT, SERT and NET were (E)-olefin S-6, EC 50 The values were 206 nM, 40 nM, and 138 nM, respectively. This analog retains the same configuration as S(+)-amphetamine, with the same number of carbons between the phenyl and amine groups as PAL-287, and a similar spatial conformation to PAL-287 compared to the more sterically hindered (Z)-olefin. Although PAL-287 was 10-fold more potent than S-6 at all three transporters, the compounds shared some activity characteristics. S-6 had a 5-fold higher potency for 5-HT / DA release, similar to the comparative compound PAL-287, which had a 3.7-fold selectivity. S-6 was 3.5-fold more potent for 5-HT release compared to NE release, similar to the 3.3-fold selectivity of PAL-287, and the two compounds had nearly equal potency for DA / NE release.
[0134] The vinylogous analogs of the present disclosure were also evaluated for their activity in 5-HT using an in vitro calcium mobilization assay. 2A , 5-HT 2B and 5-HT 2C The analogs had varying degrees of weak activity at all three receptors, making them more like S(+)-amphetamine (inactive in all three assays) than PAL-287 (Table 1). Previous functional studies revealed that PAL-287 has a strong agonist activity at 5-HT receptors. 2A Receptors and 5-HT 2B The receptor is a full agonist (EC 50 = 466 nM and 40 nM, respectively), and in 5-HT 2C Partial agonist (EC 50 =2.3nM, E MAX =20%) in 5-HT 2A At present, the vinylogous analogs are not as effective as PAL-287, as most of them are inactive (S-6, 10, 11) or have EC > 10 μM. 50 The remaining analogs had potencies in the micromolar range. 50 value and 102% E MAXThe analog S-8 was the most potent and efficacious analog. Racemic analog 8 had similar potency (EC 50 =1860 nM) and efficacy (E MAX =90%). The only other active compounds were alkyne S-4 and racemic alkene 6, which had 2.7-fold and 3-fold decreases in potency, respectively, compared to 8. These compounds were also not as potent and had E in the lower 80% range. MAX Value. 2B All analogs were inactive. This is interesting because PAL-287 is 2B It is active as an agonist, EC 50 The value is 40nM. 2C Only group III (Z)-olefins 8 and S-8 were weak agonists, with activity less than that of the control 5-HT E at 10 μM. MAX The most active transporter compound (S-6) was inactive at all three receptors, indicating that this compound may not produce the typical effects associated with agonist activity at the 5-HT2 receptor. Analog S-6 was also inactive in the in vitro 5-HT2 calcium mobilization assay, indicating no potential in vivo effects.

[0212] Dopamine transporter (DAT), norepinephrine transporter (NET), and serotonin transporter (SERT) assays
[0213] All animal studies were conducted in facilities fully accredited by the Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC), and the experiments were conducted in accordance with the Institutional Care and Use Committee (IACUC) of the National Institute on Drug Abuse Intramural Research Program (NIDA IRP). Rats were euthanized by CO2 anesthesia, and the brains were processed to produce synaptosomes as previously described (Rothman, RB, et al., Eur. J. Pharmacol. 2002, 447 (1), 51.). Synaptosomes were prepared from rat striatum for DAT determination, while synaptosomes were prepared from whole brain minus striatum and cerebellum for NET determination and SERT determination.
[0214] For uptake inhibition assays, 5 nM [ 3 H]DA, 10 nM [ 3 H] norepinephrine (NE) and 5 nM [ 3 H]5-HT was used to assess transport activity at DAT, NET, and SERT. Unlabeled blockers were included to prevent competitive transporter uptake [ 3 H] transmitter, the selectivity of the uptake assay was optimized for a single transporter. The uptake inhibition assay was performed by adding 100 μl of tissue suspension to a solution containing the test drug and [ 3 The uptake inhibition assay was terminated by rapid vacuum filtration through a Whatman GF / B filter and the retained radioactivity was quantified by liquid scintillation counting. Concentration-response curves were generated to obtain IC 50 value.
[0215] For release assays, 9 nM [ 3 H]1-methyl-4-phenylpyridinium ([ 3 H] MPP+) was used as a radiolabeled substrate for DAT and NET, while 5 nM [ 3 H] 5-HT was used as a substrate for SERT. All buffers used in the release assays contained 1 μM reserpine to block vesicular uptake of the substrate. Uptake by competitive transporters was prevented by including an unlabeled blocker. 3 H]MPP+ or [ 3[H] 5-HT, the selectivity of the release assay is optimized for a single transporter. Synaptosomes are preloaded with radiolabeled substrate in Krebs-phosphate buffer for 1 h (steady state). The release assay is initiated by adding 850 μL of preloaded synaptosomes to 150 μL of test drug. Release is terminated by vacuum filtration, and the retained radioactivity is quantified as described for uptake inhibition. Concentration-response curves are generated to obtain EC 50 value.
[0216] Substrate reversal experiments were performed to verify substrate activity. 80 The release capacity of the test compound is tested at a concentration of 1:1. If the test agent is a release agent, an uptake inhibitor reduces the effect of the test agent. If the test agent is an uptake inhibitor, then adding a second uptake inhibitor results in either no change or an increased effect in the release assay.

The cells were incubated overnight at 37°C, 5% CO. Before the assay, according to the manufacturer's instructions, calcium 5 dye (Molecular Devices) was reconstructed. The reconstructed dye was diluted 1:40 in preheated (37°C) assay buffer (1X HBSS, 20mM HEPES, 2.5mM probenecid, pH 7.4, at 37°C). The growth medium was removed, and the cells were gently washed with the preheated (37°C) assay buffer of 100 μL. The cells were incubated at 37°C, 5% CO in the diluted calcium 5 dye of 200 μL for 45 minutes. Serial dilutions of test compounds were prepared in 1% DMSO / assay buffer, aliquoted into 96-well polypropylene plates, and warmed to 37°C. Following the dye loading incubation period, cells were pretreated with 25 μL of 9% DMSO / assay buffer and incubated at 37°C for 15 min. Following the pretreatment incubation period, plates were incubated with II (Molecular Devices). Calcium-mediated fluorescence changes were monitored every 1.52 seconds over a 60-second period, where II At the 19-second time point, 25 μL of the test compound dilution was added (excitation at 485 nm, detection at 525 nm). Peak kinetic reduction (SoftMax, Molecular Devices) relative fluorescence units (RFU) were plotted against compound concentration. Data were fitted to an appropriate three-parameter logarithmic curve to generate EC 50 Value (GraphPad Prism 6.0, GraphPad Software, Inc., San Diego, CA). 5-HT 2B and 5-HT 2C Calcium mobilization assay using stable 5-HT 2B and 5-HT 2C HEK293 cells were run in the same manner except that 35,000 cells / well were used instead of 40,000 cells / well. The results are set forth in Table 1 above.
