简介
The fungus Penicillium brasilianum LaBioMMi 136 was isolated as an endophyte from Melia azedarach and has shown to be a prominent producer of great diversity of secondary metabolites, although it does not express some biosynthetic routes to other natural compounds found in Penicillium genera. The present study aimed at the diversification of P. brasilianum secondary metabolism by varying the chemical composition used for its growth. Medium composition supplemented with CuSO4 and MnSO4 locked verruculogen biosynthesis and addressed proline to the production of a series of cyclodepsipeptides identified as JBIR 113, JBIR 114 and JBIR 115, never described for this species so far. The induced cyclodepsipeptide JBIR 113 was isolated by the use of combined chromatographic procedures and identified by spectroscopic methods. The unique structure with three neighboring cyclic amino acids proline and twice pipecolinic acid is rare as natural products and has been described for the first time in terrestrial organism. Verruculogen and JBIR 113 exhibited weak antiparasitary activity against Leishmania amazonensis.
