title: Chenodeoxycholic acid-3-sulfate. Metabolism and excretion in the rat and hamster and effects on hepatic transport systems.
abstract: The metabolism and excretion of chenodeoxycholic acid-3-sulfate were determined in rats and hamsters. Constant intravenous infusions of 1, 2, and 3 mumoles/min in rats gave a maximum excretion in bile of 1.25 mumoles/min. Simultaneous infusions of sodium taurocholate at 2.0 mumoles/min and sulfobromophthalein at 0.2 mumole/min had no effects on the maximum excretion rate of chenodeoxycholic acid-3-sulfate. However, the bile acid ester sulfate caused a dose-related reduction in the excretion rate of BSP without affecting bile acid excretion rate and without a reduction in total bile flow. Chromatographic analysis of ester sulfate, a bile acid recovered in bile and urine, indicated that more than 95% had not undergone further metabolic transformation.
