- Pharmacodynamics
Cycloserine, a broad-spectrum antibiotic, may be bactericidal or bacteriostatic, depending on its concentration at the site of infection and the susceptibility of the organism. Cycloserine works by blocking the formation of these peptidoglycans. By doing this the walls of the bacteria become weak and it results in the death of the bacteria
- Mechanism of action
Cycloserine is an analog of the amino acid D-alanine. It interferes with an early step in bacterial cell wall synthesis in the cytoplasm by competitive inhibition of two enzymes, L-alanine racemase, which forms D-alanine from L-alanine, and D-alanylalanine synthetase, which incorporates D-alanine into the pentapeptide necessary for peptidoglycan formation and bacterial cell wall synthesis.
Target Actions Organism AGlutamate receptor ionotropic, NMDA 1 inhibitorHumans AD-alanine--D-alanine ligase A inhibitorEscherichia coli (strain K12) AAlanine racemase inhibitorMycobacterium avium - Absorption

- General Function
- Component of NMDA receptor complexes that function as heterotetrameric, ligand-gated ion channels with high calcium permeability and voltage-dependent sensitivity to magnesium. Channel activation requires binding of the neurotransmitter glutamate to the epsilon subunit, glycine binding to the zeta subunit, plus membrane depolarization to eliminate channel inhibition by Mg(2+) (PubMed:26875626, PubMed:26919761, PubMed:28105280, PubMed:28126851, PubMed:7685113). Sensitivity to glutamate and channel kinetics depend on the subunit composition (PubMed:26919761)
