半岛bd体育手机客户端 描述

Torcetrapib is a CETP inhibitor with IC50 of 37 nM, elevates HDL-C and reduces nonHDL-C in plasma. Inhibition of cholesteryl ester transfer protein (CETP) has been shown to have a substantial effect on plasma lipoprotein levels.

In vitro: Torcetrapib dose-dependently increases aldosterone release from H295R cells after either 24 or 48 h of treatment, this effect is mediated by calcium channel as calcium channel blockers completely blocks torcetrapib-induced corticoid release and calcium increase. Torcetrapib (1 μM) significantly increases the expression of steroidogenic gene, CYP11B2 and CYP11B1, in H295R cell lines [1].

In vivo: Researchers tested torcetrapib in rabbits fed an atherogenic diet at a dose sufficient to increase HDL-C by at least 3-fold. CETP activity was inhibited by 70–80% throughout the study. Non-HDL-C increased in both groups, but there was no difference apparent by the study’s end [2].

Clinical trial: Torcetrapib therapy resulted in an increased risk of mortality and morbidity of unknown

mechanism. Although there was evidence of an off-target effect of torcetrapib, adverse effects related to CETP inhibition cannot be ruled out [3].
