Figure Lengend Snippet: Inhibitor 19 is a potent and selective SCoV2 PLpro inhibitor (A) Chemical structures of 12 and 19 . (B and C) Inhibitor 19 was docked into the binding pocket of 12 in SCoV2 PLpro (chain A, PDB: 7E35 ). Superimposition of 19 (purple sticks) and 12 (azure sticks) indicated additional interactions between 19 and Tyr269-Gln 270 (green sticks in B) of SCoV2 PLpro (surface in C). (D) SPR analysis of 19 binding to SCoV2 PLpro; GRL0617 was used as a control. K d and SD were calculated based on three independent experiments. (E) A bar graph showing the inhibition of 11 DUBs or DUB-like proteases by 19 (10 μM) (n = 3). Data are presented as the mean ± SD (n = 3).
