天然产物 Gallinamide A 及其类似物通过抑制组织蛋白酶 L 发挥有效的抗 SARS-CoV-2 活性
摘要:
组织蛋白酶 L 是冠状病毒用于进入细胞的关键宿主半胱氨酸蛋白酶,也是新型抗 SARS-CoV-2 病毒药物的一个有前景的药物靶点。海洋天然产物 Gallinamide A 和几种合成类似物被鉴定为组织蛋白酶 L 的有效抑制剂,IC 50值在皮摩尔范围内。先导分子比参与病毒进入的其他组织蛋白酶和替代宿主蛋白酶具有选择性。 Gallinamide A 直接与细胞中的组织蛋白酶 L 相互作用,并与两种先导类似物一起在体外有效抑制 SARS-CoV-2 感染,EC 50值在纳摩尔范围内。在过表达跨膜蛋白酶丝氨酸 2 (TMPRSS2) 的细胞中观察到抗病毒活性降低;然而,当与 TMPRSS2 抑制剂联合使用时,可以实现抗病毒活性的协同改善。这些数据凸显了组织蛋白酶 L 作为 COVID-19 药物靶点的潜力,以及可能需要抑制多种病毒进入途径才能发挥功效。

An enantioselective method for Pd(II)-catalyzed cross-coupling of methylene β-C(sp3)–H bonds in cyclobutanecarboxylic acid derivatives with arylboron reagents is described. High yields and enantioselectivities were achieved through the development of chiral mono-N-protected α-amino-O-methylhydroxamic acid (MPAHA) ligands, which form a chiral complex with the Pd(II) center. This reaction provides an
