    D-Cycloserine is an amino acid analog antibiotic. D-Cycloserine acts as a competitive inhibitor of D-alanine, an essential amino acid during peptidoglycan synthesis.  It is a broad-spectrum antibiotic that can be used as a selective agent in several types of isolation media.  D-cycloserine is soluble in water.

    Mechanism of Action D-Cycloserine inhibits cell wall biosynthesis, specifically the D-Ala peptide bond formation. It competitively inhibits alanine racemase (which produces D-alanine) and D-alanine ligase, which joins the terminal 2 amino acid residues together. D-cycloserine is a ligand for the N-methyl-D-aspartate (NMDA) glycine receptor and has partial agonist characteristics, and has proven to have pharmacological activity in enhancing extinction memory.
    Spectrum D-Cycloserine is a broad-spectrum antibiotic that can be used against the causal agent of tuberculosis (Mycobacterium tuberculosis).
    Microbiology Applications D-Cycloserine can be used as a selective agent in several types of isolation media:

    Perfringens Agar - SFP and TSC selective supplements

    Clostridium difficile agar - Isolation of Clostridium difficile

    m-CP Medium - Membrane Clostridium perfringens Selective Supplement

    Molecular Formula C3H6N2O2
