A series of novel 1'-methylxanthene-9-spiro-4'-piperidines has been prepared in the search for opiate analgesics with improved pharmacological properties. It has been found that introduction of a hydroxyl group into the 4-position of the xanthenespiropiperidine nucleus produces a potent mu-opiate agonist. The structure-activity relationship of the series has been explored by use of isosteric replacements
为了寻找具有改善药理学性质的鸦片止痛药,已经制备了一系列新颖的1'-甲基黄嘌呤-9-螺-4-4'-哌啶。已经发现将羟基引入黄嘌呤螺哌啶核的4-位会产生有效的μ-鸦片激动剂。该系列的结构活性关系已通过使用酚醛羟基的等排取代进行了探索。此外,已经研究了改变哌啶环的构象的作用。有趣的是,在缺乏酚羟基的化合物中,可以通过在1'-位引入(苯基氨基)乙基而不是甲基来产生鸦片活性。
