HETEROCYCLYL-SUBSTITUTED ANTI-HYPERCHOLESTEROLEMIC COMPOUNDS

This invention provides cholesterol absorption inhibitors of Formula I: and the pharmaceutically acceptable salts thereof, wherein R12 is a hydroxylated alkyl group and R9 contains a heterocyclic ring. The compounds are useful for lowering plasma cholesterol levels, particularly LDL cholesterol, and for treating atherosclerosis and preventing atherosclerotic disease events.

Synthesis of iodinated biochemical tools related to the 2-azetidinone class of cholesterol absorption inhibitors

The discoveries of Sch 48461 and Sch 58235 and their novel pharmacology of inhibition of cholesterol absorption have prompted efforts to determine their biological mechanism of action (MOA). To this end, a series of radioiodinated analogues with good to e
