General description

Chemical structure: amino acid derivatives

Application

D-Cycloserine (DCS) has been used:
  • to study its effect on partner preference in Prairie Voles
  • to study its effect on grooming behaviour of rats
  • to determine its minimum inhibitory concentration (MIC) on 48 multidrug resistant tuberculosis (MDR-TB) isolates using the broth microdilution method
  • to study its effect on mouse model of autism, using behavioural assays

Biochem/physiol Actions

D-cycloserine (DCS) was initially known as a tuberculostatic agent. It acts as a glutamatergic partial N-methyl-D-aspartate (NMDA) agonist. It binds at the glycine-binding site of the NMDA receptor and enable the opening of the NMDA channel. DCS has a an ability to improve various forms of learning and memory hence, this drug might be effective for improving social memory and cognition. DCS can be used as a potential therapeutic for psychiatric disorders such as phobias, social anxiety, obsessive-compulsive disorder, and posttraumatic stress disorder.
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.
