CYCLO(-LEU-PRO) Chemical Properties,Uses,Production
Description
Cyclo(L-Leu-L-Pro) is a diketopiperazine metabolite that has been isolated from various bacterial and fungal species including Streptomyces. It is active against twelve strains of vancomycin-resistant enterococci (VRE) with MIC values of 12.5 μg/ml for E. faecalis strains K-99-34, K-00-184, and K-00-221. It also inhibits growth of K562, HL-60, and U937 leukemia cells in a concentration-dependent manner when used at concentrations of 1-500 μg/ml. Cyclo(L-Leu-L-Pro) also has antifouling activity, inhibiting attachment of B. amphitrite larva with an EC50 value of 0.15 mM.
Chemical Properties
White Solid
Uses
Sorbicillin analog. A bioactive secondary metabolites from terrestrial Streptomyces species TN262.
Definition
ChEBI: A homodetic cyclic peptide composed from leucyl and prolyl residues.
