SB 243213 hydrochloride is an orally active, selective and high-affinity antagonist of 5-hydroxytryptamine (5-HT)2C receptor(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)2C receptor(pKi of 9.37 and a pKb of 9.8 for human 5-HT2C receptor).
5-hydroxy-Nω-methyl Tryptamine is a metabolite of serotonin in humans that has also been found in plants. It is an agonist of the 5-HTreceptor subtype 5-HT7 (IC50 = 23 pM in a radioligand binding assay). 5-hydroxy-Nω-methyl Tryptamine increases intracellular cyclic AMP production in HEK293 cells expressing 5-HT7 (EC50 = 22 nM). It inhibits serotonin uptake in HEK293 cells expressing human serotonin transporters (IC50 = 490 nM). Elevated levels of urinary 5-hydroxy-Nω-methyl tryptamine have been found in patients with schizophrenia, depression, and epilepsy.
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 .
