Salicylhydroxamic acid is a drug that is a potent and irreversible enzyme inhibitor of the urease enzyme in various bacteria and plants; it is usually used for urinary tract infections. The molecule is similar to urea but is not hydrolyzable by urease; it thus disrupts the bacteria's metabolism through competitive inhibition. It is also a trypanocidal agent. When administered orally, it is metabolized to salicylamide, which exerts analgesic, antipyretic, and anti-inflammatory effects.
