TERIZIDONE, a structural analog of cycloserine, is a broad spectrum antibiotic used in the treatment of multidrug-resistant tuberculosis. However, its effectiveness is widely debated. Terizidone acts by inhibiting cell wall synthesis by competitively inhibiting two enzymes, L-alanine racemase and D-alanine ligase, thereby impairing peptidoglycan formation necessary for bacterial cell wall synthesis.
