The 3'-C-branched-adenosine and 2'-deoxyadenosine analogues 1-7 were tested as substrate of adenosine deaminase. The 9-(3'-C-ethynyl-beta-D-ribo-pentofuranosyl)adenine 1 and its 2'-deoxy analogue 7 were deaminated by the enzyme while the vinyl and ethyl derivatives 2 and 3 were not. The 9-(3'-C-branched-beta-D-xylo-pentofuranosyl)adenines 4-6 were deaminated by the deaminase.
测试了3′-C-支链腺苷和2′-脱氧腺苷类似物1-7作为腺苷脱氨酶的底物。该酶将9-(3'-C-乙炔基-β-D-核糖-戊呋喃糖基)腺嘌呤1及其2'-脱氧类似物7脱氨,而乙烯基和乙基衍生物2和3没有。通过脱氨酶将9-(3'-C-支链的β-D-二甲苯基-呋喃呋喃糖基)腺嘌呤4-6脱氨基。
