Abstract

Abstract: Two new heptaketides, pleosporalins H and I (1 and 2 ), as well as seven biosynthetically related known polyketides (3 –9 ) were isolated from the endophytic fungus, Pleosporales sp. F46 by employing the one strain-many compounds (OSMAC) approach. The planar, relative and absolute structures of these compounds were identified by extensive spectroscopic analysis including HRMS, NMR, optical rotations and ECD calculations. The cytotoxic efficiencies of all isolated compounds 1 –9 were evaluated against four cancer cell lines A549, CT-26, MCF-7 and MDA-MB-231. Graphical Abstract: UF0001
