with the above mentioned antiviral drugs. Our results do not support the previously expressed opinion that TSC's are selective antiviral agents. In our test systems no evidence for inhibition of virus-induced cytopathic effect was obtained. The TSC derivatives exhibited a broad range of cytotoxic effects, some at concentrations considerably below those reported to have antiviral efficacy. Several of our
衍生自各种烷基二嗪基(3-哒嗪基,4-嘧啶基,2-吡嗪基)酮和3-哒嗪甲醛的一系列新型硫代半咔唑(TSC)的合成及其对单纯疱疹病毒(HSV)和人类免疫缺陷病毒(HIV)的评估)以及确定其细胞毒性的方法。此外,还研究了这种TSC与著名的抗病毒药无环鸟苷(ACV)和3'-叠氮基3'-脱氧胸苷(AZT)联合使用的效果。在我们的实验条件下,即确定病毒对HSV-1感染HUT78细胞和MT-1细胞感染HIV-1的细胞病变作用,任何TSC都无法检测到抗病毒活性。然而,观察到了对这些快速生长的T4淋巴细胞细胞系增殖的显着影响。可以建立关于这些细胞毒性作用的明确的结构-活性关系:与吡啶,吡嗪或嘧啶衍生的TSC相比,所研究的大多数3-哒嗪基同类物的细胞毒性较小;在这些化合物中将甲基引入哒嗪系统的C-6或延长酰基部分基本上没有影响;所有带有N,N-二甲基氨基或环氨基取代基的化合物的毒性要比带有NH 2或NHR取
