analogues were tested as inhibitors of bovine liver S-adenosyl-L-homocysteine (AdoHcy) hydrolase (EC 3.3.1.1) and as inhibitors of vaccinia virus (WR) replication in clone 929 mouse L cells and the results were compared to those observed for the parent compound, 3-deaza-C-Ado. 4-Amino-1-(2,3-dihydroxy-1-propyl)imidazo[4,5-c]pyridine (14), the analogue which included the 1'-, 2'-, and 3'-carbons of 3-deaza-C-Ado
合成了一系列9-(羟烷基)-3-deazaadenines,它们是3-deazaadenosine(3-deaza-C-Ado)的碳环衍生物的类似物。测试了类似物作为牛肝S-腺苷-L-高半胱氨酸(AdoHcy)水解酶(EC 3.3.1.1)的抑制剂和牛痘病毒(WR)复制在克隆929小鼠L细胞中的抑制剂,并将结果与观察结果进行了比较对于母体化合物3-deaza-C-Ado。4-氨基-1-(2,3-二羟基-1-丙基)咪唑并[4,5-c]吡啶(14),包括3的1'-,2'-和3'-碳的类似物-deaza-C-Ado是纯化AdoHcy水解酶最有效的抑制剂。14(Ki = 768 nM)对AdoHcy水解酶的抑制作用明显小于3-deaza-C-Ado(Ki = 4 nM)的抑制作用。类似物14还显示出针对牛痘病毒复制的抑制活性,但是该活性小于3-脱氮-C-Ado所观察到的活性。4-氨基-1-(4-羟基-1-丁基)咪唑并[4
