five-step-reaction procedure and 19 novel conjugates N-[2-chloro-9-(tetrahydropyran-2-yl)-9H-purin-6-yl]-N-cyclopropylglycylamino acid benzylesters were provided. On mouse-tail flick model their in vivo analgesic activities were assayed. The results indicate that introducing Gly-OC2H5 into the 6-position of the substituted purine leads to ambiguous increase of the analgesic activity, while introducing Gly-AA-OBzl
针对慢性疼痛的化学疗法,通过五步反应方法和19种新型缀合物N- [2-氯-9-(四氢吡喃-2-)偶联了两种止痛药,取代的嘌呤和Gly-AA-OBzl。提供了(yl)-9 H-嘌呤-6-yl] -N-环丙基糖基氨基酸苄酯。在鼠尾轻弹模型上,测定了它们的体内止痛活性。结果表明,将Gly-OC 2 H 5引入取代的嘌呤的6-位导致镇痛活性的模棱两可的增加,而将Gly-AA-OBzl引入该位置导致镇痛活性的显着增加。
