compound introduction
(S)-(+)-Dimethindene maleate 是一种有效的选择性毒蕈碱 M2 受体拮抗剂 (pA2 = 7.86/7.74; pKi = 7.78)。(S)-(+)-Dimethindene maleate 对毒蕈碱 M1 (pA2 = 6.83/6.36; pKi = 7.08)，M3 (pA2 = 6.92/6.96; pKi = 6.70) 和 M4 (pKi = 7.00) 受体的亲和力较低。(S)-(+)-Dimethindene maleate 也是一种组胺 H1 受体 (histamine H1 receptor) 拮抗剂 (pA2 = 7.48） (S)-(+)-Dimethindene maleate, an enantiomer, is a potent M2-selective muscarinic receptor antagonist (pA2 = 7.86/7.74; pKi = 7.78). (S)-(+)-Dimethindene maleate shows lower affinities for the muscarinic M1 (pA2 = 6.83/6.36; pKi = 7.08), the M3 (pA2 = 6.92/6.96; pKi = 6.70) and the M4 receptors (pKi = 7.00), respectively. (S)-(+)-Dimethindene maleate also is a histamine H1 receptor antagonist (pA2 = 7.48).
