For the discovery of new antivirals against Severe Acute Respiratory Syndrome-coronavirus (SARS-CoV), we prepared and evaluated several benzoquinoline compounds as its 3C-like protease (3CLpro) inhibitors. Based on the computer modeling study that each of the two rigid benzoquinolinone and N-phenoltetrazole moieties of the compound 1 is bound to the S1 and S2 sites, respectively, of the SARS protease by forming H-bonds and hydrophobic interactions, we designed and synthesized alkylated benzoquinolines at both the sites of the hydroxyl groups. We found that the compound 2a showed five times higher inhibiting activity against the 3CLpro compared to the compound 1.
为了发现抗严重急性呼吸系统综合征-冠状病毒(SARS-CoV)的新抗病毒药物,我们制备并评估了几种苯并喹啉化合物作为其 3C 样蛋白酶(3CLpro)抑制剂。根据计算机模型研究,化合物 1 的两个刚性苯并喹啉酮和 N-苯并四唑分子分别通过形成 H 键和疏水相互作用与 SARS 蛋白酶的 S1 和 S2 位点结合,因此我们在羟基的两个位点上设计并合成了烷基化的苯并喹啉类化合物。我们发现,化合物 2a 对 3CLpro 的抑制活性是化合物 1 的五倍。
