描述

RS-127445, a selective, high anity, orally bioavailable 5-HT2B receptor antagonist. RS-127445 potently displaced [3H]-5-HT from human recombinant 5-HT2B receptor expressed in CHO-K1 cells. The anity (pKi value) of RS-127445 for the 5-HT2B receptor was 9.5+0.1. In vitro research suggests RS-127445 potently inhibited the 5-HT evoked increase in the formation of inositol phosphates in cells expressing 5-HT2B receptor. RS-127445 potently blocked the 5-HT (10 nM) evoked increases in intracellular calcium concentrations in the HEK293 cells expressing the 5-HT2B receptor (pIC50 value of 10.4+0.1). RS-127445 potently blocked the 5-HT evoked contraction of the isolated fundus. Peak plasma concentrations were rapidly achieved with the highest concentrations being found at the first time-point measured following intravenous and intraperitonael administration (0.08 h) and by 0.25 h following dosing by the oral route of administration^[3].
