Abstract
Bivalent ligand compounds synthesized from a tether composition joining two heterocyclic groups comprising furochromones, furobenzoxazinones, and benzobisdifurans. These compounds show pharmacological activity in blocking ACAT enzymes which are major regulators of cholesterol metabolism. The compounds also show activity in lowering plasma triglycerides and elevating HDL cholesterol. They are useful in the prevention or treatment of the constriction or obstruction of arterial vessels, atherosclerosis, hyperlipidemia, hypertriglyceridemia, chylomicronemia, and pancreatitis.
