SEP-363856 (SEP-856), an orally active TAAR1 and 5-HT1A agonist and CNS active psychotropic agent with a unique, non-D2/5-HT2A mechanism of action, exerts its antipsychotic-like effects. SEP-363856 (SEP-856) has the potential for the study of schizophrenia.

The free form of the compound is prone to instability, it is advisable to consider the stable salt form (Ulotaront hydrochloride) that retains the same biological activity.

In Vivo

SEP-363856 (0.3, 1 and 10 mg/kg, i.p.) is CNS active and exhibits a behavioral signature similar to known antipsychotic drugs[1].
SEP-363856 (0.3, 1 and 10 mg/kg, orally once) significantly reduces PCP-induced hyperactivity[1].
Oral SEP-363856 administration (1, 3 and 10 mg/kg) produces a dosedependent decrease in REM sleep, increase in latency to REM sleep and increase in cumulative wake (W) time[1].

Animal Model: Acute treatment with phencyclidine (PCP), which induces robust hyperactivity in rodents[1].
Dosage: 0.3, 1 and 3 mg/kg.
Administration: Orally once.
Result: Resulted in a dose-dependent inhibition of PCP-induced hyperactivity responses in C57Bl/6J mice (1-way ANOVA F (5, 59) = 18.96, p < 0.0001; Tukey’s post-hoc test, p < 0.05) with a 50% effective dose (ED50) of approximately 0.3 mg/kg.
Animal Model: Male Sprague Dawley rats[1].
Dosage: 1, 2, and 5 mg/kg.
Administration: I.V. injection. (Pharmacokinetic Analysis).
Result: 0.5 hours in mice and rats and maximum plasma concentrations reached within 6 ± 2.83 hours in monkeys.
Penetrated mouse and rat brains after oral administration (10 mg/kg), with average brain-to-plasma AUC ratios of ~3 respectively.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
