ST1936 is a selective, nanomolar affinity 5-HT6 receptor agonist with Ki values of 13 nM, 168 nM and 245 nM for human 5-HT6, 5-HT7 and 5-HT2B receptors, respectively. ST1936 also shows moderate affinity (Ki of 300 nM) for human and rat α2 adrenergic receptor[1].

| In Vitro | ST1936 appears to be relatively selective for 5-HT6 receptors, although it has shown affinity also for 5-HT2B, 5-HT1A, 5-HT7 receptor and α-adrenergic receptors when tested in a broad crossreactivity panel that comprised G-protein-coupled receptors, ion channel binding sites, enzymes, and transporters[1]. ST1936 behaves as a full 5-HT6 agonist on cloned cells and is able to increase Ca2+ concentration, phosphorylation of Fyn kinase, and regulate the activation of ERK1/2 that is a downstream target of Fyn kinase[2]. ST1936 reduces the frequency of spontaneous excitatory postsynaptic currents, with an IC50 of 1.3 μM[3]. |
| In Vivo | ST1936 (5, 10, 20 mg/kg; i.p.) increases in a dose dependent manner extracellular dopamine (DA) and NA levels in the prefrontal cortex (PFCX)[4]. ST1936 (5, 10, 20 mg/kg; i.p.) increases extracellular DA and NA levels in the nucleus accumbens (NAc) core. Doses of 10 mg/kg increases dialysate DA (peak: 179%) while higher dose increases both DA and NA dialysates (201% and 231%, respectively). Doses of 5 mg/kg does not produce any effect[4]. |
