Where is Cycloserine used?

Cycloserine is used to treat tuberculosis (TB). This is used in combination with other medications. In some cases, this may also be used to treat urinary tract infections (UTIs). This will not work for viral infections like flu or common colds. Misuse or unnecessary use of any antibiotic may cause decreased effectiveness.  

This is a broad-spectrum antibiotic that is produced by a strain of Streptomyces orchidaceous. It has also been synthesized. The Food and Drug Administration (FDA) has approved this treatment.

How does Cycloserine work?

Cycloserine is similar in structure to the amino acid d-alanine. It interferes with an early step in bacterial cell wall synthesis in the cytoplasm. It is by competitive inhibition of two enzymes called L-alanine racemase that forms D-alanine and D-alanylalanine synthetase. Wherein, it includes D-alanine into the pentapeptide needed for the formation of peptidoglycan. It also incorporates bacterial cell wall synthesis. Wherein, it kills the bacteria.
