tested as inhibitors of bovine liver and murine L929 cell S-adenosyhomocysteine (AdoHcy) hydrolase (EC 3.3.1.1) and as inhibitors of vaccinia virus replication in murine L929 cells. Compounds 1b, 2a, 2b, 4a, 4b, 7, 9a, and 9b showed the best inhibitory effects toward bovine liver AdoHcy hydrolase, with compound 4b being the most potent. The compounds that were shown to be the most potent inhibitors of the
合成了一系列的neplanocin A的类似物9-(羟基烯基)嘌呤(腺嘌呤和3-deazaadenines)。测试了类似物作为牛肝和鼠L929细胞S-腺苷半胱氨酸(AdoHcy)水解酶(EC 3.3.1.1)的抑制剂以及牛痘病毒在鼠L929细胞中复制的抑制剂。化合物1b,2a,2b,4a,4b,7、9a和9b显示出对牛肝AdoHcy水解酶的最佳抑制作用,其中化合物4b最有效。被证明是最有效的牛肝AdoHcy水解酶抑制剂的化合物均在腺嘌呤或3-deazaadenine环的顺式位置含有一个烯丙基羟基。结论是,这些无环化合物中的烯丙基羟基的顺式排列代表了neplanocin A的三羟基环戊烯基环显示出对AdoHcy水解酶的抑制作用的最低结构要求。这些无环类似物的抗病毒作用明显小于奈普兰霉素A。但是,化合物2a,2b,4a,4b和7的抗病毒活性与AdoHcy水解酶的抑制作用之间似乎存在相关性。类似
