Histone deacetylase inhibitor induced lipase inhibitors from endophytic phomopsis sp. 0391

Abstract

Seven compounds including a new one named as 13-angeloyloxy-diplosporin (1) were isolated from the endophytic Phomopsis sp. 0391 cultivated in the presence of a histone deacetylase inhibitor. All of these isolates were evaluated for lipase suppressive activities and we firstly found that compounds cytosporone B (5) and dothiorelone A (6) displayed significant lipase inhibited activities compared to the positive control (Orlistat, IC50 = 43 μg/mL) with the IC50 values at 115 and 275 μg/mL, respectively.
