Synthesis of novel analogues of the largely unknown family of 8-substituted 2′,3′-dideoxyadenosines is described. Hydrolytic deamination of two of these analogues by mammalian adenosine deaminase was utilized for an enzymatic synthesis of 2′,3′- dideoxyinosine compounds. The glycosidic bond of 2′,3′-dideoxy-8- hydtoxyadenosine is remarkably stable with respect to hydrolytic cleavage which is very unusual for a dideoxynucleoside.
本文描述了 8-取代的 2′,3′-二脱氧腺苷家族中基本未知的新型类似物的合成。利用哺乳动物腺苷脱氨酶对其中两种类似物的水解脱氨,酶法合成了 2′,3′-双脱氧腺苷化合物。2′,3′-二脱氧-8-氢氧基腺苷的糖苷键对水解裂解非常稳定,这在二脱氧核苷中是非常罕见的。
