Several novel 1,3-disubstituted β-carboline derivatives bearing a substituted carbohydrazide group at C-3 were synthesized and evaluated for their antiviral activity against vaccinal poliovirus (VP) and herpes simplex virus type 1 (HSV-1). The cytotoxicity and selectivity index of the active compounds were also evaluated. Among the synthesized derivatives, compounds 10 and 11 displayed potent activity
合成了几种新颖的在C-3带有一个取代的碳酰肼基团的1,3-二取代的β-咔啉衍生物,并评估了它们对疫苗脊髓灰质炎病毒(VP)和1型单纯疱疹病毒(HSV-1)的抗病毒活性。还评估了活性化合物的细胞毒性和选择性指数。在合成的衍生物中,化合物10和11对疫苗的脊髓灰质炎病毒和HSV-1病毒均显示出有效的活性。化合物10表现出对HSV-1病毒的最高选择性指数(SI = 2446.8)和低细胞毒性(CC 50 = 1150.0±67.3μM)。病毒产量抑制试验表明化合物10能够在病毒吸附之前和期间抑制HSV-1斑块的形成。在化合物处理过的细胞中观察到的特征性小噬斑图案表明,化合物10抑制了病毒向邻近细胞的传播。通过使用Lipinski规则确定亲脂性,拓扑极性表面积(TPSA),吸收率(%ABS)和简单分子描述符,对预测新型合成β-咔啉衍生物的ADME性质进行了计算研究。
