were assayed as inhibitors of spermidine synthase, and both 2b and 3b were found to be potent inhibitors of the enzyme. The thioether 2b is the most potent inhibitor of spermidine synthase described to date and is almost totally devoid of inhibitory activity against the closely related aminopropyltransferase, spermine synthase. This type of compound should have use as a specific inhibitor of spermidine
设计了一系列新的氨基丙基转移酶抑制剂,其中亲核氨基丙基受体与氨基丙基供体S-腺苷-1-(甲硫基)-3-丙胺(脱羧的S-腺苷甲硫氨酸)连接,形成“多底物加合物”。在当前情况下,已经合成了S-腺苷-1,8-二氨基-3-硫辛烷(2b)和相应的甲基thy盐(3b)。分析了几种这类化合物作为亚精胺合酶的抑制剂,发现2b和3b均为该酶的有效抑制剂。硫醚2b是迄今为止描述的最有效的亚精胺合酶抑制剂,几乎完全没有针对紧密相关的氨丙基转移酶精胺合酶的抑制活性。
