Several simple 8-substituted 9-alkyl- and 7,8-disubstituted 9-alkylguanine derivatives were synthesized as potential antiviral agents. These were tested for antiviral protection against a lethal Semliki Forest virus (SFV) infection in mice, and their antiviral properties were evaluated from a structure-activity standpoint. In this model system, 9-alkylguanines with the alkyl chain consisting of four
合成了几种简单的8-取代的9-烷基-和7,8-二取代的9-烷基鸟嘌呤衍生物作为潜在的抗病毒药。测试了它们在小鼠中对致命的Semliki森林病毒(SFV)感染的抗病毒保护作用,并从结构活性的角度评估了它们的抗病毒特性。在该模型系统中,发现烷基链由4至6个碳组成的9-烷基鸟嘌呤活性最高。除7-烷基-8-氧代取代基外,嘌呤环8-位的取代没有增强活性。发现这些数据支持以下假设:鸟嘌呤不需要包含完整的碳水化合物部分,从而凭借免疫增强作用而表现出抗病毒活性。因此,
