  摘要：

  Via a five-step-reaction procedure for the preparation of 19 known N-[2-chloro-9-(tetrahydropyran-2-yl)- 9H-purin-6-yl]-N-cyclopropylglycylamino acid benzylesters (6a-s) and successive removal of 9-(tetrahydropyran- 2-yl) and benzylester groups 19 novel N-[2-chloro-9H-purin-6-yl]-N-cyclopropylglycylamino acid benzylesters (7a-s) and 19 novel N-[2-chloro-9H-purin-6-yl]-N-cyclopropylglycylamino acids (8a-s) were provided. On tail-flick mouse model the in vivo analgesic activities of these 38 novel compounds were measured and most of them were defined as good analgesics. Based on Molecular Field Analysis of the pain threshold variations of the mice receiving 48 compounds in terms of the descriptors proton and methyl an equation was established. The data points (n), correlation coefficient (r), and square correlation coefficient (r(2)) of this equation were 48, 0.923, and 0.852, respectively. Using this equation pain threshold variations of 9 compounds were predicted and the errors ranged from 1.71 to 8.92. (C) 2009 Elsevier Ltd. All rights reserved.

  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。
