| Torcetrapib Usage And Synthesis |
| Chemical Properties | Off-White Low Melting Solid | | Uses | Cholesteryl ester transfer protein (CETP) inhibitor. Antilipemic; antiatherosclerotic. | | 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]. | | references | [1] hu x, dietz jd, xia c, knight dr, loging wt, smith ah, yuan h, perry da, keiser j. torcetrapib induces aldosterone and cortisol production by an intracellular calcium-mediated mechanism independently of cholesteryl ester transfer protein inhibition. endocrinology. 2009;150(5):2211-9.
