A series of 1‐thia‐4‐azaspiro[4.5]decan‐3‐ones bearing an amide group at C‐4 and various substitutions at C‐2 and C‐8 were synthesized and evaluated against human coronavirus and influenza virus. Compounds 7m, 7n, 8k, 8l, 8m, 8n, and 8p were found to inhibit human coronavirus 229E replication. The most active compound was N‐(2‐methyl‐8‐tert‐butyl‐3‐oxo‐1‐thia‐4‐azaspiro[4.5]decan‐4‐yl)‐3‐phenylpropanamide
合成了一系列 1-thia-4-azaspiro[4.5]decan-3-ones,在 C-4 处带有酰胺基团,在 C-2 和 C-8 处具有各种取代基,并针对人类冠状病毒和流感病毒进行了评估。发现化合物 7m、7n、8k、8l、8m、8n 和 8p 可抑制人类冠状病毒 229E 的复制。活性最强的化合物是 N-(2-methyl-8-tert-butyl-3-oxo-1-thia-4-azaspiro[4.5]decan-4-yl)-3-phenylpropanamide (8n),EC50 值5.5 µM,与已知的冠状病毒抑制剂 (Z)-N-[3-[4-(4-bromophenyl)-4-hydroxypiperidin-1-yl]-3-oxo-1-phenylprop-1-en-相当2-基]苯甲酰胺 (K22)。化合物 8n 和结构类似物没有抗流感病毒活性,尽管它们的支架与先前发现的一类
