spike glycoprotein (S) mediates virus entry into cells via the human Angiotensin-converting enzyme 2 (hACE2) protein located on many cell types and tissues' outer surface. This study, therefore, aimed to design and synthesize novel pyrazolone-based compounds as potential inhibitors that would interrupt the interaction between the viral spike protein and the host cell receptor to prevent SARS-CoV 2 entrance
SARS-CoV-2是在细胞质中复制的包膜正链RNA病毒。它依赖于它们的包膜与宿主细胞膜的融合以将其核衣壳递送到宿主细胞中。刺突糖蛋白(S)通过位于许多细胞类型和组织外表面的人类血管紧张素转化酶2(hACE2)蛋白介导病毒进入细胞。因此,本研究旨在设计和合成新型的基于吡唑啉酮的化合物,作为可能的抑制剂,这些化合物会中断病毒突波蛋白与宿主细胞受体之间的相互作用,从而阻止SARS-CoV 2进入细胞。设计并合成了一系列潜在的SARS-CoV-2抑制剂吡唑啉酮化合物。运用计算技术,评估了所设计化合物对刺突蛋白和hACE2的抑制潜力。硅内分析的结合自由能结果表明,三种化合物(7i,7k和8f)和六种化合物(7b,7h,7k,8d,8g和8h)显示出对SARS的更高和更好的结合高亲和力-CoV-2 Sgp和hACE-2分别与标准药物头孢哌酮(CFZ)和MLN-4760相比。此外,在结合抑制剂后对两种
