New Series of BPL Inhibitors To Probe the Ribose-Binding Pocket of Staphylococcus aureus Biotin Protein Ligase.

ABSTRACT: Replacing the labile adenosinyl-substituted phosphoanhydride of biotinyl-5'-AMP with a N1-benzyl substituted 1,2,3-triazole gave a new truncated series of inhibitors of Staphylococcus aureus biotin protein ligase (SaBPL). The benzyl group presents to the ribose-binding pocket of SaBPL based on in silico docking. Halogenated benzyl derivatives (12t, 12u, 12w, and 12x) proved to be the most potent inhibitors of SaBPL. These derivatives inhibited the growth of S. aureus ATCC49775 and displayed low cytotoxicity against HepG2 cells.
