Pactimibe sulfate (CS-505) is a dual ACAT1/2 inhibitor, acting on ACAT1 (IC50: 4.9 μM) and ACAT2 (IC50: 3.0 μM). It inhibits oleoyl-CoA non-competitively (Ki: 5.6 μM) and significantly inhibits cholesterol ester formation (IC50: 6.7 μM). Pactimibe sulfate reduces plasma cholesterol activity and has anti-atherogenic potential.
