relationship studies of a class of novel small molecule inhibitors against CHIKV and the discovery of a new potent inhibitor (compound 6a). The starting point of the optimization process was N-ethyl-6-methyl-2-(4-(4-fluorophenylsulfonyl)piperazine-1-yl)pyrimidine-4-amine (1) with an EC50 of 8.68 μM, a CC50 of 122 μM, and therefore a resulting selectivity index (SI) of 14.2. The optimized compound 6a, however,
基孔肯雅热病毒(CHIKV)是一种蚊子传播的甲型病毒,是基孔肯雅热(CHIKF)的病原体。尽管它已经重新成为流行病的威胁,但到目前为止,尚无疫苗或药物疗法可用于预防或治疗感染。在本文中,我们描述了一类针对CHIKV的新型小分子抑制剂的合成与构效关系研究,以及新的强效抑制剂(化合物6a)的发现。优化过程的起点是N-乙基-6-甲基-2-(4-(4-氟苯基磺酰基)哌嗪-1-基)嘧啶-4-胺(1),EC50为8.68μM,CC50为122μM,因此得到的选择性指数(SI)为14.2。然而,优化后的化合物6a显示出低得多的微摩尔抗病毒活性(EC50值为3.95μM),
