Abstract
In the course of searching for cholesteryl ester transfer protein (CETP) inhibitors from natural sources, a new type of CETP inhibitor, [10]-dehydrogingerdione (1), was isolated from the extract of rhizomes of Zingiber officinale Roscoe. By NMR spectroscopic analysis of its 1HNMR, 13C-NMR, and 1H-1H COSY, HMBC, HMQC and NOESY, more precise structure, compared with its originally proposed structures, of [10]-dehydrogingerdione has been elucidated. This active compound inhibited human plasma CETP with IC50 values of 35 μM.
