Biochem/physiol Actions

S15535, a benzodioxane, is a selective but partial agonist of histamine serotonin 1A (5-HT1A) receptor. It activates presynaptic 5-HT1A receptors and suppresses the release of hippocampal 5-HT. It acts as an anxiolytic agent and modulates the cholinergic and cognitive function in rodents.
Potent, orally active, partial 5-HT1A receptor agonist

Application

S15535 has been used as a serotonin 1A receptor (5-HT1A) agonist in zebrafish.
S15535 may be used in histamine 5-HT1A-medaited cell signaling studies.

The novel, potential anxiolytic, S 15535 (4-(benzodioxan-5-yl)1-(indan-2-yl)piperazine), is an agonist and antagonist (weak partial agonist) at pre- and postsynaptic serotonin (5-HT)1A receptors, respectively. Herein, we characterized its influence on dialysate levels of 5-HT, dopamine (DA) and NAD simultaneously determined in

This study examined the influence of the highly selective 5-HT1A receptor ligands, flesinoxan, S 15535, and WAY 100,635, upon the electrical activity of dopaminergic neurons in the ventral tegmental area (VTA), as compared to serotonergic neurons in the dorsal raphe

The Journal of pharmacology and experimental therapeutics, 282(1), 148-161 (1997-07-01)
In these studies, we characterized the influence of the novel benzodioxopiperazine serotonin (5-HT)1A ligand, S 15535, on the release of 5-HT in rat hippocampus and compared its potential anxiolytic properties with those of the 5-HT1A receptor partial agonist, buspirone, the

In humans and other primates low cerebrospinal fluid (CSF) levels of the major serotonin (5-HT) metabolite 5-hydroxyindoleacetic acid (5-HIAA) have been correlated to high aggressiveness. This finding forms the basis of the 5-HT deficiency hypothesis of aggression. Surprisingly, this correlation
