SEP-363856 (SEP363856; SEP-856), the S-enantiomer of SEP-363856, is a novel and potent orally bioactive trace amine-associated receptor 1 (TAAR1) agonist with serotonin 1A (5-HT1A) agonist activity. Also a CNS active psychotropic agent with a Unique, Non-D 2 Receptor Mechanism of Action. It has the potential to be used for the treatment of acute schizophrenia that does not bind to the dopamine-2 (D2) receptor but binds to trace amine-associated (TAAR) receptors and 5-HT1A receptors. May also be used for other neuropsychiatric disorders.
| Targets |
TAAR; 5-HT1A Receptor
|
|---|---|
| ln Vitro |
SEP-363856 (10 μM) has a >50% specific binding inhibition of D2, 5-HT1A, 5-HT1B, 5-HT1D, 5-HT2A, 5-HT2B, 5-HT2C, and 5-HT7 receptor[1].
|
| ln Vivo |
SEP-363856 displays behavioral traits resembling those of well-known antipsychotics and possesses CNS activity at concentrations of 0.3, 1 and 10 mg/kg, i.p. [1]. The oral dosage of SEP-363856 (0.3, 1 and 10 mg/kg) is effective in reducing PCP-induced hyperactivity [1]. REM sleep is reduced, REM sleep latency is increased, and cumulative wake time (W) is increased when SEP-363856 (1, 3 and 10 mg/kg) is administered orally [1].

| Enzyme Assay |
n Vitro and In Vivo 5-HT1A and D2 Receptor Occupancy Studies.[1] In vitro autoradiography was used to determine the effects of SEP-856 on [3H]-8-OH-DPAT binding to 5-HT1A receptors in rat brain sections. In vivo occupancy of SEP-856 at D2 receptors was measured with [3H]-raclopride in Sprague-Dawley rats and with [18F]-fallypride–positron emission tomography in nonhuman primates. For details, refer to Supplemental Material.[1]

| Cell Assay |
Patch–Clamp Recordings in the Dorsal Raphe Nucleus and Ventral Tegmental Area.[1] In vitro whole–cell patch–clamp recording techniques were used in isolated slice preparations (male C57BL/6J mice, 4–16 weeks) of the dorsal raphe nucleus (DRN) and ventral tegmental area (VTA) to investigate the effects of SEP-856 on neuronal activity. The experiments examined the effects of SEP-856 (1–30 μM) on the activity of DRN and VTA neurons that were characterized by their electrophysiological properties and/or their sensitivity to application of the 5-HT1A receptor agonist 8-OH-DPAT (DPAT; 10 μM). Subsequently, effects mediated via the TAAR1 and/or via the 5-HT1A receptor were investigated using the selective antagonist N-(3-Ethoxy-phenyl)-4-pyrrolidin-1-yl-3-trifluoromethyl-benzamide (EPPTB; 0.05–1 μM) and the selective antagonist WAY-100635 (WAY-635; 10 μM), respectively. All compounds were dissolved in either DMSO or ddH2O and diluted with artificial cerebrospinal fluid (aCSF) to a final concentration from a minimum 1000-fold higher stock concentration (maximum slice DMSO concentration 0.1%). Whole–cell patch–clamp recordings were performed at room temperature using the blind version of the patch–clamp technique with either Axopatch 1D or Multiclamp 700B amplifiers. For detailed methods, refer to the Supplemental Material.[1]

| Animal Protocol |
Animal/Disease Models: Acute treatment with phencyclidine (PCP) can induce intense hyperactivity in rodents [1].
Doses: 0.3, 1 and 3 mg/kg. Doses: Take once orally. Experimental Results: Dose-dependent inhibition of PCP-induced hyperkinetic responses in C57Bl/6J mice (one-way ANOVA F (5, 59) = 18.96, p < 0.0001; Tukey's post hoc test, p < 0.05) 50% effective dose (ED50) is approximately 0.3 mg/kg. Animal/Disease Models: Male Sprague Dawley rat[1]. Doses: 1, 2 and 5 mg/kg. Mode of Route of Administration: intravenous (iv) (iv)injection. (pharmacokinetic/PK/PK analysis). Experimental Results: Maximum plasma concentrations were reached within 0.5 hrs (hrs (hours)) in mice and rats and within 6 ± 2.83 hrs (hrs (hours)) in monkeys. After oral administration (10 mg/kg), it penetrates the mouse and rat brains with mean brain to plasma AUC ratios of approximately 3, respectively. |

| Additional Infomation |
Ulotaront is a member of the class of thienopyrans that is 4,7-dihydro-5H-thieno[2,3-c]pyran substituted by a (methylamino)methyl at position 7S. It is a trace amine-associated receptor 1 and serotonin 5-HT1A receptors agonist that has demonstrated efficacy in the treatment of patients with schizophrenia. It has a role as a trace amine-associated receptor 1 agonist, a psychotropic drug, an antidepressant, an antipsychotic agent and a serotonergic agonist. It is a secondary amino compound and a thienopyran.
SEP-363856 is a novel psychotropic drug being investigated for the treatment of schizophrenia. Unlike other drugs used for this condition, SEP-363856 does not bind to the dopamine D2 receptors, but exerts actions on the trace amine–associated receptor 1 (TAAR1) and 5-hydroxytryptamine type 1A (5-HT1A). SEP-363856 was developed by Sunovion pharmaceuticals. An initial clinical study has shown this drug may be effective against both positive and negative symptoms of schizophrenia. Negative symptoms of schizophrenia are more difficult to treat and may include flattened affect, anhedonia, and social withdrawal. Additional clinical trials of SEP-363856 are required to confirm the safety and efficacy of this drug. |
