Design, synthesis and biological evaluation of a series of 5-chloropyridine ester-derived severe acute respiratory syndrome-coronavirus chymotrypsin-like protease inhibitors is described. Position of the carboxylate functionality is critical to potency. Inhibitor 10 with a 5-chloropyridinyl ester at position 4 of the indole ring is the most potent inhibitor with a SARS-CoV 3CLpro IC(50) value of 30
描述了一系列5-氯吡啶酯衍生的严重急性呼吸综合征-冠状病毒糜蛋白酶样蛋白酶抑制剂的设计、合成和生物学评价。羧酸酯官能团的位置对于效力至关重要。吲哚环 4 位具有 5-氯吡啶酯的抑制剂 10 是最有效的抑制剂,其 SARS-CoV 3CLpro IC(50) 值为 30 nM,抗病毒 EC(50) 值为 6.9 microM。分子对接研究提供了这些抑制剂可能的结合模式。
