A series of novel N‐substituted sophocarpinic acid derivatives was designed, synthesized, and evaluated for their anti‐enteroviral activities against coxsackievirus type B3 (CVB3) and coxsackievirus type B6 (CVB6) in Vero cells. Structure–activity relationship analysis revealed that the introduction of a benzenesulfonyl moiety on the 12‐nitrogen atom in (E)‐β,γ‐sophocarpinic acid might significantly
设计,合成和评估了一系列新颖的N取代的果几磷酸衍生物对Vero细胞中针对B3型柯萨奇病毒(CVB3)和B6型柯萨奇病毒(CVB6)的抗肠病毒活性。结构-活性关系分析表明,在(E)-β,γ-次果酸中的12-氮原子上引入苯磺酰基部分可能会显着增强抗CVB3活性。间的衍生物,(É)-12- ñ - (米-cyanobenzenesulfonyl)-β,γ-sophocarpinic酸(11米),具有一元-cyanobenzenesulfonyl基,表现出对CVB3有效的活性与107的选择性指数(SI) 。此外,化合物11 m也表现出良好的口腔药代动力学分布,具有7.29的AUC值μ中号 ħ -1大鼠,和良好的安全性,通过在小鼠中口服途径,与LD 50 > 1000毫克公斤的值-1 ; 这些值表明有可药物治疗的特征。因此,化合物11 m被选作有希望的CVB3抑制剂作进一步研究。我们认为(E)-β,γ-
