4'alpha-position did not show any cytotoxicity. The antiviral activities of these nucleosides against HSV-1, HSV-2, and HIV-1 in vitro were also examined. Compounds 22 and 23 showed antiviral activities against HSV-1 and HSV-2 without showing significant toxicity to the host cells (MRC-5 cells). Although almost all of the nucleosides showed anti-HIV-1 activities, they were also cytotoxic to the host cells (MT-4)
由2'-脱氧胞苷或尿苷合成了一系列的4'α-C-支链嘧啶核苷。在2'-脱氧胞苷系列中,在4'α-位置的取代基在体外以Me(23)> CN(22)> C(symbol)CH(21)> CH =的顺序影响对L1210小鼠白血病细胞的细胞毒性。 CH(2)(19)> Et(24)> CH = CHCl(20)。然而,在4'α位具有乙炔基和氰基的尿苷和胞苷衍生物没有显示出任何细胞毒性。还检查了这些核苷在体外对HSV-1,HSV-2和HIV-1的抗病毒活性。化合物22和23显示出针对HSV-1和HSV-2的抗病毒活性,而没有显示出对宿主细胞(MRC-5细胞)的明显毒性。尽管几乎所有核苷都具有抗HIV-1活性,
