CAS 68-41-7

(+)-Cycloserine

Description:

(+)-Cycloserine, with the CAS number 68-41-7, is a cyclic amino acid that serves as an antibiotic and is primarily used in the treatment of tuberculosis. It is characterized by its unique structure, which includes a five-membered ring containing two functional groups: an amino group and a hydroxyl group. This compound exhibits a chiral center, resulting in its designation as the (+) enantiomer, which is biologically active. (+)-Cycloserine acts by inhibiting bacterial cell wall synthesis, specifically targeting the enzyme D-alanine racemase, which is crucial for the production of D-alanine, a building block of peptidoglycan in bacterial cell walls. The substance is soluble in water and exhibits moderate stability under standard conditions. However, it can be sensitive to light and moisture, necessitating proper storage conditions. Side effects may include neurological symptoms, which require monitoring during treatment. Overall, (+)-Cycloserine is an important compound in antimicrobial therapy, particularly for drug-resistant strains of Mycobacterium tuberculosis.

Applications 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 antibiotic against Gram-negative bacteria. There is evidence that D-cycloserine can enhance neuronal changes that lead to learning.
