(1R,cis)-2-(3-Amino-2,2-dimethylcyclobutyl)ethanol (4) was used as a precursor in the synthesis of cyclobutyl nucleoside analogues containing guanine, 8-azaguanine, adenine or 8-azaadenine. All the compounds were evaluated as antiviral agents in a variety of assay systems. Some activity was noted for compound 13, 17, 19 and 20 against vaccinia virus and for compounds 11, 12, 13, 17, 19 and 20 against herpes simplex virus, at concentrations that were up to 10-fold below the cytotoxic concentrations for the host cells.
(1R,cis)-2-(3-氨基-2,2-二甲基环丁基)乙醇(4)被用作合成含有鸟嘌呤、8-氮鸟嘌呤、腺嘌呤或8-氮腺嘌呤的环丁基核苷类似物的前体。所有化合物均在多种测定系统中被评估为抗病毒剂。化合物13、17、19和20对天花病毒表现出一定活性,化合物11、12、13、17、19和20对单纯疱疹病毒也表现出一定活性,且这些浓度均比宿主细胞的细胞毒性浓度低10倍。
