synthesized as potential opioid analgesics. Using a combination of in vitro and in vivo test systems, the receptor profiles of selected compounds have been assessed and in some instances distinguish between mu- and kappa-receptor agonists. In general, introduction of a 6-exocyclic methylene group into the trans-3-(decahydro-4a-isoquinolinyl)phenol system enhanced both antinociceptive activity and kappa-opioid
已经合成了一系列反式-3-(6-和7-取代的十氢-4a-异喹啉基)酚和反式-3-(八氢-4a-异喹啉基)酚作为潜在的阿片类镇痛药。使用体外和体内测试系统的组合,已评估了所选化合物的受体概况,并在某些情况下区分了mu和κ受体激动剂。通常,将6-外环亚甲基引入反式-3-(十氢-4a-异喹啉基)苯酚体系既增强了抗伤害感受活性,又增强了κ-阿片受体的选择性。对于每个系列,带有N-环丙基甲基取代基的类似物表现出更高的κ-受体选择性,而N-甲基衍生物则表现出更高的mu-受体选择性。7位取代的化合物(3b)的抗伤害感受力明显低于其6位取代的对应物(3a),八氢异喹啉类似物具有中等活性。轴向的8-甲基-6-环外亚甲基异喹啉(20)是小鼠腹部收缩测定中最有效的化合物(ED50 = 0.05 mg / kg sc),而赤道的8-甲基异构体(16)的效力明显较低( ED 50 = 3.3mg / kg sc)。
