RNA 病毒 SARS-CoV-2 和登革热对全世界人类健康构成重大威胁,它们的蛋白酶(Mpro;NS2B/NS3)被认为是药物开发的有希望的目标。我们介绍了这两种蛋白酶的新型苯并氧硼杂环戊烯抑制剂的合成和生物学评价。在生化检测中,最活跃的化合物针对 SARS-CoV-2 Mpro 的活性达到了个位数微摩尔。针对登革热 NS2B/NS3 蛋白酶的最活性物质在细胞中具有亚微摩尔活性 (EC50 0.54 μM),并抑制细胞培养物中的 DENV-2 复制。大多数苯并氧杂硼杂环戊烯没有相关的细胞毒性或显着的脱靶抑制。此外,该课程还展示了对所评估的蛋白酶的被动膜渗透性和稳定性。该化合物类别可能有助于开发具有抗 DENV 或 SARS-CoV-2 活性的抗病毒药物。
The RNA viruses SARS-CoV-2 and dengue pose a major threat to human health worldwide and their proteases (Mpro; NS2B/NS3) are considered as promising targets for drug development. We present the synthesis and biological evaluation of novel benzoxaborole inhibitors of these two proteases. The most active compound achieves single-digit micromolar activity against SARS-CoV-2 Mpro in a biochemical assay. The most active substance against dengue NS2B/NS3 protease has submicromolar activity in cells (EC50 0.54 μM) and inhibits DENV-2 replication in cell culture. Most benzoxaboroles had no relevant cytotoxicity or significant off-target inhibition. Furthermore, the class demonstrated passive membrane penetration and stability against the evaluated proteases. This compound class may contribute to the development of antiviral agents with activity against DENV or SARS-CoV-2.
