生物活性 | Mepyramine maleate, a first generation antihistamine, is an antagonist ofhistamine H1 receptor, withKds of 0.8 nM, 5200 nM and >3000 nM for H1, H2, and H3 receptor, respectively, and apKdof 9.4 for H1 receptor. | ||||||||||||||||
IC50& Target | Kd: 0.8 nM (Histamine H1 receptor), 5200 nM (Histamine H2 receptor), >3000 nM (Histamine H3 receptor)[1] | ||||||||||||||||
体外研究 (In Vitro) | Mepyramine maleate is an antagonist of histamine H1 receptor, with Kds of 0.8 nM, 5200 nM and >3000 nM for H1, H2, and H3 receptor, respectively[1], and a pKdof 9.4 for H1 receptor[2]. Mepyramine binds to the H1 receptor with different Kds in Guinea pig brain (0.8 nM), rat brain (9.1 nM) and DDT1-MF-2 and BC3H1 cell (276 nM)[1]. Mepyramine decreases the InsP levels in CHO-gpH1 cells, with log EC50of -7.94 ± 0.11, and reduces the the maximal response to ATP in CHO-gpH1 cells[3]. | ||||||||||||||||
体内研究 (In Vivo) | Mepyramine obviously decreases the second phase of nociceptive response via i.p at 10 and 20 mg/kg, but shows no significant effect at 5 mg/kg in rats[4]. | ||||||||||||||||
