Two subseries of nonquaternized (5a-10a) and quaternized derivatives (5b-10b) related to oxotremorine and oxotremorine-M were synthesized and tested. The agonist potency at the muscarinic receptor subtypes of the new compounds was estimated in three classical in vitro functional assays: M1 rabbit vas deferens, M2 guinea pig left atrium and M3 guinea pig ileum. In addition, the occurrence of central
合成并测试了与氧代雷莫林和氧代雷莫林-M有关的两个非季铵化(5a-10a)和季铵化衍生物(5b-10b)的亚系列。在三种经典的体外功能测定中,估计了新化合物毒蕈碱受体亚型的激动剂效力:M1兔输精管,M2豚鼠左心房和M3豚鼠回肠。另外,将中毒蕈毒碱作用的发生评估为小鼠腹膜内给药后的致发色活性。在体外测试中,所有衍生物均表现出非选择性毒蕈碱活性,在某些情况下其效力值超过了参考化合物(即8b)。仅对类氧代短发膜样衍生物9a证明了其功能选择性,该衍生物表现为混合的M3激动剂/ M1拮抗剂(pD2 = 5.85; pA2 = 4.76,分别)。在体内试验中,非季铵化合物能够引起中央毒蕈碱作用,其效力与体外观察到的效力顺序平行。
