Description and Uses

Acetohydroxamic acid is a potent, non-competitive and irreversible inhibitor of bacterial urease (Ki≈lO^-7M). This enzyme, which is widely distributed in plants and bacteria, but not in mammalian cells, catalyzes the decomposition of urea to ammonia. Elevated urinary ammonia levels can reduce the antibacterial effectiveness of a number of agents. Thus, acetohydroxamic acid is useful as adjunctive therapy to decrease urinary ammonia and alkalinity in patients with chronic urea-splitting urinary infection. Such infections are a leading cause of recurring complications and death in paraplegics.

A urease inhibitor. Used in the synthesis
