5-HT2B, pKi:9.5

5-HT2B, pIC50:10.4

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].

溶解方案

动物实验：请根据您的动物给药指南选择适当的溶解方案。
以下溶解方案都请先按照体外实验的方式配制澄清的储备液，再依次添加助溶剂：
——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议现用现配，当天使用；以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶
