Description

General description

Chemical structure: amino acid derivatives

Application

D-Cycloserine acts as inhibitor of various enzymes.

Biochem/physiol Actions

Mode of Action: Inhibits cell wall biosynthesis (D-Ala peptide bond formation). Also prevents conversion of D-Ala to L-Ala. Bacteriostatic.
Partial agonist at the glycine modulatory site of NMDA glutamatergic receptors; antibiotic against Gram-negative bacteria.
Mode of Resistance: D-Ala transport interference.
