target for anti-DENV drug discovery. In the current work, a potent NS2B-NS3 covalent inhibitor 23 (IC50 = 6.0 nM, kinac/Ki = 1581 M–1 s–1) was discovered through the chemical modification of a published covalent inhibitor 1 (IC50 = 500 nM, kinac/Ki = 156.1 M–1 s–1), followed by in vitro assay. Further comprehensive structure–activity relationship analysis through covalent docking and molecular dynamics
登革热病毒(DENV)是一种节肢动物传播的黄病毒,在过去的几十年里发展迅速,成为世界上分布最广的虫媒病毒。NS2B-NS3 在病毒复制和病毒蛋白成熟中的重要作用使其成为抗 DENV 药物发现的最有希望的靶标。在目前的工作中,通过对已发表的共价抑制剂1 ( IC 50 = 500 nM,k inac / K i = 156.1 M–1 s –1 ),然后进行体外测定。通过共价对接和分子动力学模拟进一步全面的结构-活性关系分析提供了对靶向 NS2B-NS3 的共价抑制剂结合模式的信息理解。
