Acyl-CoA:cholesterolacyltransferase (ACAT) is the primary enzyme involved in intracellular cholesterol esterification. Arterial wall infiltration by macrophages and subsequent uncontrolled esterification of cholesterol leading to foam cell formation is believed to be an important process which leads to the development of fatty streaks. Inhibitors of the ACAT enzyme may retard this atherogenic process

potent, bioavailable ACAT inhibitor may have beneficial effects in the treatment of atherosclerosis by (i) reducing the absorption of dietary cholesterol, (ii) reducing the secretion of very low density lipoproteins into plasma from the liver, and (iii) preventing the transformation of arterial macrophages into foam cells. We have found that a mevalonate derivative 2, which contains a 4,5-diphenyl-1H-imidazol-2-yl

The compounds are 5/6-pyridyl-phenyl-2,3-dihydroimidazo[2,1-b]thiazoles which have utility as intermediates and/or as having antiarthritic activity. A preferred group of compounds is 5-(4-pyridyl)-6-(4-substituted phenyl)-2,3-dihydroimidazo[2,1-b]thiazoles which have significant anti-arthritic activity.
