| Description | Cyclo(Leu-Val) is a cyclic dipeptide from the fermentation broth of F8712 strain. |
| In vitro | To search for bioactive compounds from marine microbes. METHODS AND RESULTS: Pyricularia oryzae was used to screen microbes.Compounds extracted with EtOAc from the fermentation broth of F8712 strain(an active microbe screened out) were separated.The chemical structures of the separated compounds were identified by ~(1)HNMR,~(13)CNMR and ESI-MS techniques. Six cyclic dipeptides,cyclo(Ala-Leu),cyclo(Ala-Ile),cyclo(Ile-Pro),cyclo(Val-Pro),cyclo(Leu-Pro) and Cyclo(Leu-Val),were obtained. CONCLUSIONS:: None of the 6 cyclodipeptides has any anti-Pyricularia oryzae activities.Compound Ⅴ has potent inhibitory effects on Vibrio anguillarm with a minimum inhibitory concentration of 0.07 μg/ml. |
