Samelisant free base
Samelisant (SUVN-G3031) free base is a potent and selective histamine H3 receptor (H3R) inverse agonist with good brain penetration and oral bioavailability. Samelisant free base has a similar binding affinity towards human (hH3R; Ki=8.7 nM) and rat (rH3R;Ki=9.8 nM) H3R indicating no inter-species differences. Samelisant free base can be used for the research of sleep-related disorders.

Biological Activity
Samelisant free base displays inverse agonist activity and it exhibits very high selectivity towards H3R. The pEC50 value of histamine (8.5) for human H3 receptor increases to 8.2, 7.3 and 6.2 after treatment with 1, 10 and 100 nM of Samelisant, respectively. The pEC50 value of histamine (8.2) for rat H3 receptor increases to 7.9, 7.4 and 6.4 after treatment with 1, 10 and 100 nmol/L of Samelisant, respectively[1].
Samelisant free base binds to the orthosteric site in a reversible manner with Kb values of 1.3 nM and 1.1 nM deduced from pA2 value for human and rat H3R, respectively[1].
Samelisant free base also modulates dopamine and norepinephrine levels in the cerebral cortex while it has no effects on dopamine levels in the striatum or nucleus accumbens[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Samelisant free base also produces a significant decrease in direct rapid eye movement (REM) sleep onset (DREM) episodes, demonstrating its anticataplectic effects in an animal model relevant to narcolepsy[1].
Samelisant free base treatment in mice produces a dose-dependent increase in tele-methylhistamine levels indicating the activation of histaminergic neurotransmission[1].
