NOVEL 3-PHENOXY-4-PYRONE, 3-PHENOXY-4-PYRIDONE, OR 4-PYRIDONE DERIVATIVES, METHOD FOR PREPARING SAME, AND ANTIMICROBIAL COMPOSITION CONTAINING SAME AS AN ACTIVE INGREDIENT

摘要

The present invention relates to novel 3-phenoxy-4-pyrone, 3-phenoxy-4-pyridone, or 4-pyridone derivatives, or to pharmaceutically acceptable salts thereof, to a method for preparing same, and to an antibacterial composition containing same as an active ingredient. The composition containing the novel 3-phenoxy-4-pyrone, 3-phenoxy-4-pyridone, or 4-pyridone derivatives according to the present invention effectively inhibits enoyl-ACP reductase (RabI), which serves as a bacterial fatty acid biosynthesis enzyme, and thus can be effectively used as an antibacterial agent.
