Enoyl-ACP reductase (ENR), the product of the FabI gene, from Bacillus anthracis (BaENR) is responsible for catalyzing the final step of bacterial fatty acid biosynthesis. A number of novel 2-pyridone derivatives were synthesized and shown to be potent inhibitors of BaENR. ... Novel 2-pyridone derivatives were synthesized and shown to be potent inhibitors of enoyl-ACP reductase from Bacillus anthracis. ... Our structure optimization studies were based on predicted ...
