No antiviral drugs to treat or prevent life-threatening flavivirus infections such as those caused by mosquito-borne Dengue (DENV) and more recently Zika (ZIKV) viruses are yet available. We aim to develop, through a structure-based drug design approach, novel inhibitorstargeting the NS5 AdoMet-dependent mRNA methyltransferase (MTase), a viral protein involved in the RNA capping process essential
目前尚无抗病毒药物可用于治疗或预防威胁生命的黄病毒感染,例如由蚊媒登革热(DENV)和最近的寨卡病毒(ZIKV)引起的感染。我们旨在通过基于结构的药物设计方法,开发针对NS5 AdoMet依赖性mRNA甲基转移酶(MTase)的新型抑制剂,该抑制剂是黄病毒复制所必需的RNA封闭过程中的一种病毒蛋白。在这里,我们描述了使用基于片段和结构指导的链接技术确定的匹配(5)的优化,该链接与AdoMet绑定口袋的近端站点绑定。X射线晶体学结构和计算对接用于指导我们的优化过程,并导致化合物30和33(DENV IC50 = 26μM和23μM; ZIKV IC 50 分别为28μM和19μM ),这是黄病毒MTase的新型非核苷抑制剂的两个代表。

novel series of arylurea and arylamide derivatives 1a–z, 2a–d having aminoquinazoline scaffold was designed and synthesized. Their in vitro antiproliferativeactivitiesagainst RT112 bladder cancer cellline and inhibitory activitiesagainst FGFR3 kinase were tested. Most compounds showed good antiproliferativeactivitiesagainst RT112 bladder cancer cellline, and arylurea compounds 1a–z were more
