Abstract

This manuscript describes the preparation of new small molecule inhibitors of Bacillus anthracis lethal factor. Our starting point was the symmetrical, bis-quinolinyl compound 1 (NSC 12155). Optimization of one half of this molecule led to new LF inhibitors that were desymmetrized to afford more drug-like compounds.

Keywords: Anthrax; Bacillus anthracis; Botulinum neurotoxin A; Desymmetrized; Hybrid compound; Lethal factor; Light chain; Matrix metalloprotease; Quinoline; Zinc metalloprotease.
