Abstract
Compounds which are useful as inhibitors of cholesterol biosynthesis and thus as hypocholesterolemic agents are provided which have a quinoline or a pyridine anchor attached by means of a linker to a binding domain sidechain, which compounds inhibit the enzyme 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase.
