Use of Cyclo(L-Phe-L-Pro)

Cyclo(L-Phe-L-Pro), isolated from Pseudomonas fluorescens and Pseudomonas alcaligenes cell-free culture supernatants is an antifungal cyclic dipeptide[1]. Cyclo(L-Phe-L-Pro) inhibits IFN-β production by interfering with retinoic-acid-inducible gene-I (RIG-I) activation[2]. Cyclo(L-Phe-L-Pro) exhibits free-radical scavenging activity with the IC50 of 24 µM in the DPPH assay[3].
