Agomelatine (S-20098) L(+)-Tartaric acid is a specific agonist of MT1 and MT2 receptors (Kis: 0.1, 0.06, 0.12, and 0.27 nM for CHO-hMT1, HEK-hMT1, CHO-hMT2, and HEK-hMT2). It also is a selective 5-HT2Creceptor antagonist (pKis: 6.4 and 6.2 at native (porcine) and cloned (human) 5-HT2Creceptors).
SB 242084 hydrochloride is a 5-HT2Creceptor antagonist(pKi=9.0) that displays 158- and 100-fold selectivity over 5-HT2A and 5-HT2B receptors respectively.IC50 value: 9.0(pKi) [1]Target: 5-HT2C antagonistin vitro: SB 242084 had over 100-fold selectivity over a range of other 5-HT, dopamine and adrenergic receptors. In studies of 5-HT-stimulated phosphatidylinositol hydrolysis using SH-SY5Y cells stably expressing the cloned human 5-HT2Creceptor, SB 242084 acted as an antagonist with a pKb of 9.3, which closely resembled its corresponding receptor binding affinity [1].in vivo: SB 242084 potently inhibited m-chlorophenylpiperazine (mCPP, 7 mgkg i.p. 20 min pre-test)-induced hypolocomotion in rats, a model of in vivo central 5-HT2Creceptor function, with an ID50 of 0.11 mg kg i.p., and 2.0 mg kg p.o. SB 242084 (0.1-1 mg kg i.p.) exhibited an anxiolytic-like profile in the rat social interaction test, increasing time spent in social interaction, but having no effect on locomotion. SB 242084 (0.1-1 mg kg i.p.) also markedly increased punished responding in a rat Geller-Seifter conflict test of anxiety, but had no consistent effect on unpunished responding [1].
SB 243213 hydrochloride is an orally active, selective and high-affinity antagonist of 5-hydroxytryptamine (5-HT)2Creceptor(pKi of 9.37 and a pKb of 9.8).It has improved anxiolytic profile and has the potential for schizophrenia and motor disorders.
SB 243213 dihydrochloride is an orally active, selective and high-affinity antagonist of 5-hydroxytryptamine (5-HT)2Creceptor(pKi of 9.37 and a pKb of 9.8 for human 5-HT2Creceptor).
Sarizotan (EMD 128130) is an orally active compound that acts as an agonist for serotonin 5-HT 1A receptors and dopamine receptors. It has shown potent activity with IC 50 values of 6.5 nM for rat 5-HT 1A , 0.1 nM for human 5-HT 1A , 15.1 nM for rat D 2 , 17 nM for human D 2 , 6.8 nM for human D 3 , and 2.4 nM for human D 4.2 .
