Time course production of indole alkaloids by an endophytic strain of Penicillium brasilianum cultivated in rice

Nat Prod Res. 2013;27(11):967-74. doi: 10.1080/14786419.2012.701210. Epub 2012 Jul 3.

Abstract

During our studies concerning endophytic fungi, two indole alkaloids were co-produced with verruculogen by Penicillium brasilianum isolated from Melia azedarach (Meliaceae). The compounds were isolated by the use of combined chromatographic procedures and identified by physical methods, mainly 1D- and 2D-NMR experiments. This article also describes the production of verruculogen TR-2, first described for this species of Penicillium, and a verruculogen TR-2C-11 epimer, that is a novel fungal natural product. The kinetic production of verruculogen and verruculogen TR-2 produced by P. brasilianum were evaluated in order to understand the involvement of verruculogen TR-2 in verruculogen biosynthesis.
