Pipemidic acid , a derivative of Piromidic acid, is an antibacterial agent. Pipemidic acid inhibits DNA gyrase. Pipemidic acid is active against gram-negative bacteria including Pseudomonas aeruginosa as well as some gram-positive bacteria. Pipemidic acid can be used for the research of intestinal, urinary, and biliary tract infections.
