摘要

Isoflavones have been suggested to have hypolipidemic effects. As these compounds undergo complex metabolismin the body, the biological actions of isoflavone metabolites are largely unknown. We studied the hypolipidemic effectsof two isoflavone metabolites initially identified in the human urine, cis-tetrahydrodaidzein (NV-04) and transtetrahydrodaidzein(NV-05) in apolipoprotein(E)-deficient mice fed with a high-fat diet. NV-04 and NV-05 were mixed inthe food (200 mg per kg) and the treatment lasted for 16 weeks. NV-04 decreased plasma levels of LDL by 30%, triglyceridesby 65% and increased HDL/LDL ratio by 70%. These effects of NV-04 are specific since its stereoisomer NV-05 isless effective. Notably, the effects of NV-04 are observed in the absence of apolipoprotein(E), therefore our results suggestthat using cis-tetrahydrodaidzein as a complimentary medicine in hyperlipidemic patients with apolipoprotein(E) dysfunctionswarrants further investigations.
