Description
Cyclo(L-Pro-L-Val) is a diketopiperazine formed by the fusion of valine and proline, reported as a secondary metabolite of fungi and bacteria. In Pseudomonas aeruginosa, cyclo(L-Pro-L-Val) is capable of activating N-acylhomoserine lactones (AHLs). Cyclo(L-Pro-L-Val) is also capable of activating or antagonizing other LuxR-based quorum-sensing systems.

 Cyclo(L-Pro-L-Val) is soluble in ethanol, methanol, DMF or DMSO. Limited water solubility

    CAS Number

    2854-40-2

    Molecular Formula

    C10H16N2O2

    Molecular Weight

    196.3

    Mechanism of Action

    While the mode of action of the cyclo(L-Pro-L-Val) is not known, its activity suggests the existence of cross talk among bacterial signalling systems.
