    • Chemical Class:

      A 4-amino-1,2-oxazolidin-3-one that has <stereo>R</stereo> configuration. It is an antibiotic produced by <ital>Streptomyces garyphalus</ital> or <ital>S. orchidaceus</ital> and is used as part of a m ulti-drug regimen for the treatment of tuberculosis when resistance to, or toxicity from, primary drugs has developed. An analogue of <stereo>D</stereo>-alanine, it interferes with bacterial cell wall synthesis in the cytoplasm by competitive inhibition of <stereo>L</stereo>-alanine racemase (which forms <stereo>D</stereo>-alanine from <stereo>L</stereo>-alanine) and <stereo>D</stereo>-alanine<em _dash/><stereo>D</stereo>-alanine ligase (which incorporates <stereo>D</stereo>-alanine into the pentapeptide required for peptidoglycan formation and bacterial cell wall synthesis). ChEBI CHEBI:40009, CHEBI:74159
      A zwitterion resulting from the transfer of a proton from the ring nitrogen to the primary amino group of <stereo>D</stereo>-cycloserine. The major species at pH 7.3. ChEBI CHEBI:40009, CHEBI:74159

      D-Cycloserine is an analog of the amino acid D-alanine.;Target: AntibacterialD-Cycloserine selectively potentiated the duration of motor cortical excitability enhancements induced by anodal tDCS. D-Cycloserine alone did not modulate excitability [1]. Participants receiving d-cycloserine in addition to exposure therapy reported significantly less social anxiety compared with patients receiving exposure therapy plus placebo. Controlled effect sizes were in the medium to large range [2]. Chronic D-cycloserine significantly reduced nicotine self-administration selectively in rats with low baseline nicotine use, but was ineffective with the rats with higher levels of baseline nicotine self-administration [3].
