LCAT activator compound A is an activator of Lecithin:cholesterol acyltransferase (LCAT) including some mutant LCATs found in Familial LCAT Deficiency (FLD). LCAT activator compound A forms a covalent hydrophobic adduct with LCAT Cys 31. The chronic treatment with LCAT activator compound A results in a significant increase in HDLc, HDL particle, size, plasma apolipoprotein A-I level, plasma cholesteryl ester to free cholesterol ratio, and a significant reduction in very low-density lipoprotein cholesterol in hamsters.
