Abstract

Two new C12 polyketides, cladospolides E and F (1 and 2), together with four known derivatives seco-patulolides A and C (3 and 4), 11-hydroxy-γ-dodecalactone (5) and iso-cladospolide B (6), were isolated from a soft coral-derived fungus Cladosporium sp. TZP-29. Their structures, including the absolute configurations, were elucidated by spectroscopic analysis, modified Mosher's method, and the analysis of their biogenesis. All compounds were non-cytotoxic while compounds 1 and 3-5 showed potent lipid-lowering activity in HepG2 hepatocytes.

Keywords
