ACAT inhibitors derived from hetero-Diels-Alder cycloadducts of thioaldehydes
摘要:
Acyl-CoA:cholesterol acyltransferase (ACAT) is the enzyme largely responsible for intracellular cholesterol esterification. A systemic inhibitor of ACAT is believed to be able to slow or even reverse the atherosclerotic process. Towards that goal, a series of cyclic sulfides, derived from the hetero-Diels-Alder reaction of thioaldehydes with 1,3-dienes, and bearing carboxamide substituents, were prepared and evaluated for in vitro (in several tissues and species) and ex vivo ACAT inhibition. Minor changes in subsequent structure were found to have a significant effect in optimization of the biological activity of this series of compounds.

The reaction of cyanomethyl dithiocarbamate and S-cyanomethyl thiocarbamate with alkyl halides in aqueous medium selectively gave mono- and di-alkylated products. The treatment of the alkylated products with coned sulfuric acid gave α-mercaptoalkanoic acid esters.
