biocompatible SuFEx click chemistry. A high-throughput screening hit benzyl (cyanome-thyl)carbamate (Ki = 8 µM) against a bacterial cysteine protease SpeB was modified with a SuFExable iminosulfur oxydifluoride [RN=S(O)F2] motif, rapidly diversified into 460 analogs in overnight reactions, and the products directly screened to yield drug-like inhibitors with 480-fold higher potency (Ki = 18 nM). We showed
