and its derivatives can potently inhibit FBPase by covalently binding to a new C128 allosteric site distinct from the original C128 site in APO FBPase. Further identification of the allosteric inhibition mechanism reveals that the covalent binding of a fragment of 214 will result in the movement of C128 and the dissociation of helix H4 (123–128), which in turn allows S123 to more easily formnew hydrogen
Discovery of unsymmetrical aromatic disulfides as novel inhibitors of SARS-CoV main protease: Chemical synthesis, biological evaluation, molecular docking and 3D-QSAR study
outbreak of severe acute respiratory syndrome (SARS) in 2003 had caused a high rate of mortality. Main protease (Mpro) of SARS-associated coronavirus (SARS-CoV) is an important target to discover pharmaceutical compounds for the therapy of this life-threatening disease. During the course of screening new anti-SARS agents, we have identified that a series of unsymmetrical aromatic disulfides inhibited SARS-CoV
2003年,世界范围内的严重急性呼吸道综合症(SARS)爆发导致了很高的死亡率。SARS相关冠状病毒(SARS-CoV)的主要蛋白酶(M pro)是发现用于治疗这种威胁生命的疾病的药物的重要靶标。在筛选新的抗SARS药物的过程中,我们发现一系列不对称的芳香族二硫化物首次显着抑制了SARS-CoV M pro。本文中,化学合成了40种新型不对称芳族二硫化物,并在体外评估了它们对SARS-CoV M pro的生物学活性。这些新型化合物显示出优异的IC 50数据范围为0.516–5.954μM。初步研究表明,这些二硫化物是可逆的和竞争性抑制剂。通过分子对接模拟生成了可能的结合模式,并构建了一个比较场分析(CoMFA)模型来理解结构-活性关系。因此,本研究为设计和鉴定具有全新化学结构的抗SARS药物提供了有意义的指导。
