3,4-dihydroxy Hydrocinnamic acid (L-Aspartic acid dibenzyl ester) amide inhibits human ACAT-1 and ACAT-2 (Acyl-Coenzyme A cyltransferase-1 and -2) equally with an IC50 of about 60 μM. ACAT-1 and ACAT-2 catalyze the formation of long chain fatty acyl-coenzyme A and cholesterol esters from cholesterol, and may play a role in the development of atherosclerosis. This chemical inhibits human ACAT-1 and ACAT-2 with an IC50 values of 95 and 81 μM, respectively and also inhibits copper-mediated oxidation of low density lipoproteins by 91% at a concentration of 2 μM.
