  • Name: D-Cycloserine
  • Chemical Name: 3-Isoxazolidinone,4-amino-, (4R)
  • CAS Number: 68-41-7
  • Molecular Formula: C3H6N2O2
  • Molecular Weight: 102.092
  • Catalog: Biochemical Common amino acids and protein drugs
  • Create Date: 2018-02-14 08:00:00

  • 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].
