3 and 4 The prime role of the coronary arteries is to supply blood into the heart; hence its blockage results into

a serious shortage of blood in the heart muscles, which in turn deprives the myocardial tissues of oxygen. Such a lack of oxygen in the heart muscles results into a painful indication known as angina. The hardening of the plaques may even stop the total blood supply into the heart which then results into a heart attack.5 Low density lipoprotein (LDL) and the cholesterol selleckchem are the prime contributors in the formation of such plaques inside the blood vessels.6 The high-density lipoprotein (HDL) however also contributes to the formation of the plaques.7 Cholesteryl ester transfer protein (CETP) is a plasma glycoprotein that facilitates the transfer of cholesteryl esters (CE) and triglycerides from HDL to LDL/VLDL.8 HDL transports the cholesterol into the liver, where it is finally broken down, while LDL helps in deposition of the cholesterol into the inner walls of the arteries. Hence high quantities of LDL and lower quantities of the HDL inside the blood stream increase the risk of heart attack. LDL carries much more Cholesterol than HDL. CETP is one such plasma glycoprotein that transfers www.selleckchem.com/products/DAPT-GSI-IX.html the CE from the HDL to the LDL, thereby

increasing the risk of the cholesterol deposition in the inner walls of the arteries.9 CETP inhibition has hence been proven as a potential target in the war against heart diseases.10 and 11 Recent works have revealed that CETP may be inhibited by the drugs such as Dalcetrapib, Torcetrapib, JIT-705 and Anacetrapib.8 After inhibition of CETP the cholesterol level of HDL increases which in turn controls the cholesterol transportation.12 However, Torcetrapib was rejected in phase III of clinical trials due to its enormous side effects.11 Quantitative structure–activity relationship (QSAR) has been proven as the most fruitful tool in the comparative evaluation of the structure of a drug with its biological activity.13

The physicochemical properties of a drug are related to its structure which helps us correlate and optimize the therapeutic effects and Thalidomide minimize the toxicity of the drug substance.14 The tool has been utilized by the medicinal chemists to investigate new drug substance or optimization of the existing ones.15 and 16 A series of N–N-disubstituted trifluoro-3-amino-2-propanol derivatives were retrieved from published study.17 These compounds were evaluated as cholesteryl ester transfer protein (CETP) inhibitors. Authors have extensively studied structure–activity relationship (SAR) by substituting various functional groups at the 1- and 2-positions to achieve an effective CETP inhibition. Eighty one structures (H explicit 2D and 3D) of N–N-disubstituted trifluoro-3-amino-2-propanol were sketched and optimized using Marvin Sketch (developed by ChemAxon Company).
