2'-"up" (arabino) configuration for enhancement of antiviral effectiveness is demonstrated by the superior activity of 2'-fluoro-5-iodo-ara-C [3a, FIAC] to that of 2'-fluoro-5-iodo-ribo-C. Of all the nucleosides tested herein, FIAC exhibited the most potent in vitro activity against HSV. 2'-Chloro-5-iodo- and -5-methyl-ara-C (3b and 4b) were 37 to greater than 500 times more effective in vitro against HSV
描述了几种2'-卤素-5-取代-阿拉伯呋喃糖基胞嘧啶和-尿嘧啶的合成,并研究了结构与体外抗疱疹病毒活性的关系。与2'-溴类似物的2'-氯相比,那些含有2'-氟功能的阿拉伯核苷通常表现出更有效的抗疱疹病毒(HSV)活性。2'-氟-5-碘-ara-C [3a,FIAC]优于2'-氟-5-碘-ara-C [3a,FIAC]的活性证明了氟在2'-“ up”(阿拉伯糖)构型中增强抗病毒效力的重要性。 '-氟-5-碘-核糖-C。在本文测试的所有核苷中,FIAC表现出最强的抗HSV体外活性。2'
