DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE INVENTION

This invention includes novel lipophilic polyamines which are useful for treating hypercholesterolemia and intermediates thereto. Background of the Invention
Cholesterol is probably the sole precursor of bile acids. During normal digestion, bile acids are secreted into the intestines. A major portion of the bile acid is absorbed from the intestinal tract and returned to the liver via the enterohepatic circulation system. Only very small amounts of bile acids are found in normal serum. Polymeric anion exchange resins are known to combine with the bile acids in the intestine to form an insoluble complex which is excreted in the feces. This results in partial removal of bile acids from the enterohepatic circulation by preventing their reabsorption. The increased fecal loss of bile acids leads to an increased oxidation of cholesterol to bile acids, a decrease in beta lipoprotein or low density lipoprotein plasma levels and a decrease in plasma cholesterol levels. Although excretion of bile acids produces an increase in hepatic synthesis of cholesterol, plasma cholesterol falls. These anion exchange resins are not systemically absorbed or digested although large quantities, up to 54 grams of the formulated resin per day for cholestyramine resin powder, are needed. These resins are not water soluble but are typically administered as an aqueous suspension.
Colestipol-niacin therapy has recently been shown to significantly increase the regression of atherosclerosis in drug-treated subjects. D. H. Blankenhorn et al., JAMA, 1987, 257:3233-3240. Others have found cholestyramine reduces the incidence of coronary heart disease in treated patients. Lipid Research Clinics Program, JAMA. 1984 251:351-364. With the positive effects of resins on coronary heart disease, one must balance the sometimes poor patient compliance. Therefore the medical community has recognized the need for new effective drugs of this type. S. M. Grundy, "Drugs Affecting Lipid Metabolism"; R. Paoletti Ed., Springer Verlag: Berlin 1987, pp. 34-41. Information Disclosure
