Evacetrapib (LY2484595) (LY2484595) is a potent and selective inhibitor of CETP with IC50 of 5.5 nM, elevates HDL cholesterol without increases in aldosterone or blood pressure. Phase 3.

Evacetrapib (LY2484595) inhibits human plasma CETP protein with IC50 of 26 nM. Evacetrapib (LY2484595) (< 10 μM) does not induce aldosterone or cortisol synthesis in H295R cells. [1]

Evacetrapib (LY2484595) (30 mg/kg, orally) results in 98.4%, 98.6%, and 18.4% inhibition of CETP activity at 4 hours, 8 hours and 24 hours post dose respectively in human ApoAI and CETP double transgenic mice. Evacetrapib (LY2484595) (30 mg/kg) results in 129.7% increase in HDL-C 8 hours after oral administration. The ED50 values of CETP inhibitory activity 8 hours post oral dosing for Evacetrapib (LY2484595) in two dose-response studies are calculated to be 3.5 mg/kg and 4.1 mg/kg respectively. Evacetrapib (LY2484595) (< 200 mg/kg) does not increase blood pressure in Zucker diabetic fatty rats. [1]

Human CETP cDNA is amplified from a human liver cDNA library and the sequence is confirmed to be identical to the published sequence. The cDNA is subcloned into a pcDNA3.1 vector, under the control of CMV promoter. A stable line is established in CV1 cells in which the above-mentioned construct is used to express the recombinant human CETP. The medium contained the secreted recombinant CETP protein and the amount (19 ng/μL) is quantified by an ELISA kit. The medium is then aliquoted in 0.2% BSA and stored at -80°C. The stock CETP protein is diluted 150-fold in CETP buffer (10 mM Tris, 150 mM NaCl, and 2 mM EDTA) before use. The assay is set up in a 96-well plate. Each well received 97.5 μL diluted CETP protein (final concentration 7 nM) and 2.5 μL of compound stock. After a 30 min incubation at 37°C, 5 μL of substrate stock (the same stock used in the human plasma CETP assay), 0.16 μL of VLDL stock (2.5 mg/mL, Intracel) and 145 μL of CETP buffer are added, and the incubation is continued for another 4 h. Signal is read for the human plasma CETP assay[1].
