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。

The critical consequences of human cytomegalovirus (HCMV) infection in the transplant population and in congenitally infected infants, the limited treatment options for HCMV, and the rise of resistant mutants toward existing therapies has fueled the search for new anti-HCMV agents. A pp28-luciferase recombinant HCMV was used as a reporter system for high-throughput screening of HCMV inhibitors. Approximately 400 000 compounds from existing libraries were screened. Subsequent validation assays using resynthesized compounds, several virus strains, and detailed virology assays resulted in the identification of five structurally unique and selective HCMV inhibitors, active at sub to low micromolar concentrations. Further characterization revealed that each compound inhibited a specific stage of HCMV replication. One compound was also active against herpes simplex virus (HSV1 and HSV2), and another compound was active against Epstein-Barr virus (EBV). Drug combination studies revealed that all five compounds were additive with ganciclovir or letermovir. Future studies will focus on optimization of these new anti-HCMV compounds along with mechanistic studies.
