C-activating sponge natural product alotaketal C (1) potently inhibits the infection of human Calu-3 lung cells by SARS-CoV-2 Omicron BA.1 and BA.5 variants. Simplified analogs of 1 have been synthesized and tested for anti-SARS-CoV-2 activity providing SAR data for the antiviral pharmacophore of 1. Analogs 19 and 23, which are missing the C-11 substituents in 1 and have modified C-13 appendages, are ∼2-
蛋白激酶 C 激活海绵天然产物 alotaketal C ( 1 ) 有效抑制 SARS-CoV-2 Omicron BA.1 和 BA.5 变体对人 Calu-3 肺细胞的感染。1的简化类似物已被合成并测试其抗 SARS-CoV-2 活性,为1的抗病毒药效团提供 SAR 数据。类似物19和23缺少1中的 C-11 取代基并修饰了 C-13 附属物,其效力比1强约 2 至 7 倍,并且具有相同或更大的选择性指数。
