Synthesis of 1-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)uracils containing a vinyl (4a), 2-halovinyl (4b-d), or ethyl substituent at C-5 was achieved. These nucleosides were found to be about a log order less active than 2'-fluoro-5-iodo-ara-C (FIAC) against HSV-1, but they are much less cytotoxic against normal human lymphocytes than FIAC. Nucleosides 4a and 4e showed good activity against HSV-1
合成了在C-5处含有乙烯基(4a),2-卤代戊基(4b-d)或乙基取代基的1-(2-脱氧-2-氟-β-D-阿拉伯呋喃糖基)尿嘧啶。发现这些核苷对HSV-1的活性比2'-氟-5-碘-ara-C(FIAC)的对数活性低,但与FIAC相比,它们对正常人淋巴细胞的细胞毒性小得多。核苷4a和4e对HSV-1(分别为ED50 = 0.16和0.24 microM)和HSV-2(ED50 = 0.69和0.65 microM)表现出良好的活性,几乎没有细胞毒性(ID50大于100 microM)。
