Product Name: D-Cycloserine
CAS: 68-41-7
MF: C3H6N2O2
MW: 102.09
EINECS: 200-688-4
Chemical Properties White to pale yellow cryst. powder
Usage antibacterial (tuberculostatic)
Usage D-Cycloserine inhibits cell wall biosynthesis (D-Ala peptide bond formation). D-Cycloserine also prevents conversion of D-Ala to L-Ala. D-Cycloserine is an bacteriostatic. D-Cycloserine is an antibiot ic against Gram-negative bacteria.

Antibiotic drugs. Used for infection of drug-resistant tuberculosis bacilli.

Cycloserine can be prepared by fermentation or direct synthesis. The bacteria produced by the fermentation method is Actinomyces laven-dulae, and the fermentation medium is dextrin, glucose, starch, soybean meal, yeast powder, ammonium sulfate, ammonium nitrate, calcium carbonate, sodium chloride, magnesium sulfate and Soybean oil and so on. The synthesis method is to react β-aminooxyalanine ethyl ester dihydrochloride with potassium hydroxide, that is, cyclization to obtain cycloserine.
