The petroleum ether extract of Panax ginseng showed a significant inhibition of the diacylglycerol acyltransferase (DGAT) enzyme from rat liver microsomes. Bioactivity-guided fractionation led to the isolation of two new polyacetylenic compounds, (9 R,10 S)-epoxyheptadecan-4,6-diyn-3-one ( 1) and 1-methoxy-(9 R,10 S)-epoxyheptadecan-4,6-diyn-3-one ( 2). Their chemical structures were elucidated on
人参的石油醚提取物对大鼠肝微粒体的二酰基甘油酰基转移酶(DGAT)酶具有显着抑制作用。生物活性指导的分馏导致分离出两种新的聚炔化合物,(9 R,10 S)-环氧庚烷-4,6-diyn-3-one(1)和1-甲氧基-(9 R,10 S)-环氧庚烷-4,6-diyn-3-one(2)。在光谱证据和不对称合成的基础上阐明了它们的化学结构。获得的IC50值为9 microg / mL(1)和32 microg / mL(2)。
