Simvastatin 34-40 sterol O-acyltransferase 1 Oryctolagus cuniculus 239-243 2742865-5 1989 To clarify the mechanism of action, the effects of MK-733 on acyl coenzyme A:cholesterol acyltransferase (ACAT) and cholesterol esterase activities, which are thought to participate in the absorption of cholesterol, were examined. Simvastatin 51-57 sterol O-acyltransferase 1 Oryctolagus cuniculus 106-110 2742865-7 1989 10 mg/kg) of MK-733 to cholesterol-fed rabbits was found to inhibit the increase in serum total cholesterol levels, and caused a 70% reduction in ACAT activity in microsomes of intestinal mucosa relative to those observed in concurrent control rabbits. Simvastatin 13-19 sterol O-acyltransferase 1 Oryctolagus cuniculus 146-150 2742865-9 1989 The inhibitory effect of MK-733 on cholesterol absorption in cholesterol-fed rabbits is though to be related to a reduction in microsomal ACAT activity in the intestinal mucosa. Simvastatin 25-31 sterol O-acyltransferase 1 Oryctolagus cuniculus 138-142 2776246-3 1989 A kinetic analysis using a Lineweaver-Burk plot indicated that MK-733 is a competitive inhibitor of ACAT, with a Ki value of 1.2 x 10(-5) M. Simvastatin 63-69 sterol O-acyltransferase 1 Oryctolagus cuniculus 100-104
