Torcetrapib Usage And Synthesis

Chemical Properties

Off-White Low Melting Solid

Uses

Cholesteryl ester transfer protein (CETP) inhibitor. Antilipemic; antiatherosclerotic.

Definition

ChEBI: Torcetrapib is a member of quinolines, a carbamate ester and a member of (trifluoromethyl)benzenes. It has a role as an anticholesteremic drug and a CETP inhibitor.

Biological Activity

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].
