A series of aprophen [(N,N-diethylamino)ethyl 2,2-diphenylpropionate] analogues, called cylexphenes, were synthesized with alterations in (1) the chain length of the amine portion of the ester, (2) the alkyl groups on the amino alcohol, and (3) a cyclohexyl group replacing one of the phenyl rings. The antimuscarinic activities of these analogues were assessed in two pharmacological assays: the inhibition
合成了一系列被称为cyphenphenes的二萘嵌苯酚[(N,N-二乙基氨基)乙基2,2-二苯基丙酸酯]类似物,其变化是(1)酯的胺部分的链长,(2)烷基上的烷基(3)取代苯环之一的环己基。在两个药理学分析中评估了这些类似物的抗毒蕈碱活性:抑制乙酰胆碱诱导的豚鼠回肠收缩,以及阻断卡巴胆碱刺激的大鼠胰腺腺泡细胞释放α-淀粉酶。这两个组织代表M3(回肠)和M3(胰腺)毒蕈碱受体亚型。此外,还评估了类似物对[3H] NMS与所选细胞膜结合的竞争抑制作用,每个细胞膜仅包含m1,M2,m3,或M4毒蕈碱受体亚型。m1和m3受体被稳定转染到A9 L细胞中。用环己基取代一个萘基的一个苯基,使所有类似物对胰腺泡毒蕈碱受体亚型的选择性比回肠亚型高10倍以上,其中(N,N-二甲基氨基)丙基类似物具有对胰腺受体亚型的最大选择性超过30倍。当检查[3H] NMS与M2亚型的结合时,与母体化合物相比,cycyphe
