Cytotoxic and anti-inflammatory constituents from Momordica cochinchinensis seeds

Abstract

Five new lignans mubiesins A − E (1–5), together with twenty-seven known compounds (6–32), were isolated from the cytotoxicity and anti-inflammation portions of Momordica cochinchinensis seeds which were widely used for various tumors and inflammations. Their structures were elucidated by extensive spectroscopic analyses (HR-MS, UV, CD, IR, 1D-NMR, and 2D-NMR). Their cytotoxic and anti-inflammatory activities were evaluated in vitro. Various lignans and saponins showed the significant activities, they could obviously inhibit the growth of tumor cells and the release of NO and TNF-α in RAW 264.7 cells induced by LPS.
