Description

The present application relates to a novel tetrahydroquinoline derivative, a process for its preparation, its use alone or in combinations for the treatment and / or prevention of diseases and its use for the manufacture of medicaments, in particular as an inhibitor of cholesterol ester transfer protein (CETP) Treatment and / or prevention cardiovascular Diseases, in particular hypolipoproteinemias, dyslipidaemias, hypertriglyceridemias, hyperlipidemias, hypercholesterolemias and Arteriosclerosis.

By Atherosclerosis-related coronary heart disease are among the Major causes of death in modern society. In a variety Studies have shown that low plasma levels of HDL cholesterol is an important risk factor for the development of atherosclerosis [Barter and Rye, Atherosclerosis 121, 1-12 (1996)]. HDL (high density lipoprotein) in addition to LDL (low density lipoprotein) and VLDL (very low density lipoprotein) a class of lipoproteins whose main function is the transport of lipids, such as Example cholesterol, cholesterol esters, triglycerides, fatty acids or phospholipids, is in the blood. High LDL cholesterol levels (> 160 mg / dl) and low HDL cholesterol levels (<40 mg / dl) essential for the development of arteriosclerosis in [ATP III Guidelines, Report of the NCEP Expert Panel]. In addition to coronary heart disease are also peripheral vascular disease as well as stroke due to unfavorable HDL / LDL ratios promoted in their creation. New methods to increase Consequently, HDL cholesterol in the plasma is a therapeutic agent meaningful enrichment in the prevention and treatment of arteriosclerosis and associated diseases.

Cholesterinester transfer protein (CETP) mediates the exchange of cholesterol esters and triglycerides between the various lipoproteins in the blood [Tall, J. Lipid Res. 34, 1255-74 (1993)]. Of particular importance is the transfer of cholesterol esters from the HDL to the LDL, which leads to a lowering of HDL cholesterol plasma levels leads. The inhibition of CETP should therefore increase the Plasma levels of HDL cholesterol and a lowering of plasma levels of LDL cholesterol and thus to a therapeutically useful Influencing the Lipid Profile in the Plasma [McCarthy, Medicinal Res. Rev. 13, 139-59 (1993); Sitori, Pharmac. Ther. 67, 443-47 (1995); Swenson, J. Biol. Chem. 264, 14318 (1989)].
