Discovery of pentacyclic triterpene 3β-ester derivatives as a new class of cholesterol ester transfer protein inhibitors
A series of pentacyclic triterpene 3β-ester derivatives were designed, synthesized and evaluated as a new class of cholesteryl ester transfer protein (CETP) inhibitors for the treatment of dyslipidemia. In vitro screening assay showed that 5 out of 30 compounds displayed moderate inhibiting human CETP activity with IC50s less than 10 μM. Among them, compound 20 (IC50 = 2.3 μM) had the most potent biological activity, and effectively ameliorated plasma lipid levels of human adipose tissue specific CETP transgenic (ap2-CETPTg) mice and guinea pigs. Additional safety evaluation (no blood pressure elevation in guinea pigs) and pharmacokinetics studies indicated that the potential druggability for compound 20 which is a promising lead for development of a new class of CETP inhibitors for the treatment of dyslipidemia.
