Acivicin is an analog of glutamine. It is an inhibitor of gamma-glutamyl transferase.

It is a fermentation product of Streptomyces sviceus.[1] It interferes with glutamate metabolism and inhibits glutamate dependent synthesis of enzymes, and is thereby potentially helpful in treatment of solid tumors.[2]

After its discovery in 1972, acivicin was studied as an anti-cancer agent, but trials were unsuccessful due to toxicity.[3]
