discovery of thieno[3,2-b]pyrrole 1b that displayed good antiviral activity against CHIKV infection in vitro. However, it has a short half-life in the presence of human liver microsomes (HLMs) (T1/2 = 2.91 min). Herein, we report further optimization studies in which potential metabolically labile sites on compound 1b were removed or modified, resulting in the identification of thieno[3,2-b]pyrrole 20 and
Chikungunya病毒(CHIKV)是一种重新出现的载体传播的alpha病毒,目前尚无针对CHIKV的经过批准的有效抗病毒治疗。我们先前报道了噻吩并[3,2- b ]吡咯1b的发现,它在体外对CHIKV感染表现出良好的抗病毒活性。但是,它在人肝微粒体(HLM)存在下的半衰期很短(T 1/2 = 2.91分钟)。本文中,我们报告了进一步的优化研究,其中化合物1b上潜在的代谢不稳定位点被去除或修饰,从而鉴定了噻吩并[3,2- b ]吡咯20和吡咯并[2,3- d ]噻唑23c在HLM中具有高达17倍的代谢半衰期增加,并具有良好的体内药代动力学特性。化合物20不仅减缓了病毒RNA的产生,并显示出对其他α病毒和CHIKV分离株的广谱抗病毒活性,而且还显示出有限的细胞毒性作用(CC 50 > 100μM)。这些研究已经确定了两种化合物,它们有可能作为抗CHIKV感染的抗病毒药物进行进一步开发。
