To assess the importance of de novo cholesterol synthesis for bile salt formation, the effects of ML-236B (an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A reductase) on biliary excretion of bile salts and lipids were studied in rats with permanent catheters in bile duct, heart and duodenum. In rats having their bile diverted continuously for 8 days, duodenal administration of ML-236B (50 mg/kg) caused an immediate transient choleresis, which subsided after 2 h. Concomitant with the choleresis concentrations of bile salt, phospholipid and cholesterol fell, but this decrease was maintained for 6 h. Consequently, ML-236B inhibited biliary output salts and lipids from the second till the sixth hour after injection. The kinetics of biliary excretion of intravenously injected [14C]taurocholate were not affected by ML-236B administration. In rats having their biliary catheter connected to the duodenal catheter, or in rats with prolonged bile diversion but treated with mevalonolactone, ML-236B again caused a transient choleresis (having subsided after 2 h), but now did not affect biliary excretion of bile salts and lipids. It is concluded that (1) ML-236B causes a transient bile salt-independent choleresis, (2) ML-236B depresses excretion of bile salts and lipids by blocking mevalonate synthesis and not by blocking the bile salt or lipid transport, (3) biliary excretions of phospholipids and cholesterol partly depend on excretion of bile salt, and (4) in rats with a prolonged total bile diversion newly formed mevalonate is a major substrate for bile salt synthesis.
