• 개요

  RS 127445 is an orally bioavailable and potent antagonist of the serotonin (5-HT) receptor subtype 5-HT_2B (K_i = 0.32 nM). It is selective for 5-HT_2B over other 5-HT receptor subtypes (K_i = >3 μM for 5-HT_1A, 5-HT_1B, 5-HT_2A, 5-HT_2C, 5-HT₃, 5-HT₅, and 5-HT₆). RS 127445 reduces contraction of rat isolated stomach fundus (pA₂ = 9.5) and lowers intracellular increases in calcium (IC₅₀ = 0.04 nM) induced by 5-HT . It also blocks (±)-α-methyl-5-HT-induced relaxation of isolated rat jugular veins (pA₂ = 9.95). RS 127445 (1-30 mg/kg) reduces peristaltic frequency and fecal output in mice in a dose-dependent manner. Systemic administration of RS 127445 (0.16 mg/kg) reduces basal, but not cocaine-induced, dopamine outflow in the nucleus accumbens of rats and decreases hyperlocomotion induced by cocaine (Item Nos. ISO60176 | 16186 | 22165) or quinpirole.
