โœฆ Synopsis

Hepatic metabolism of salicylic acid was studied using a single-pass liver perfusion technique. Livers obtained from male, Sprague-Dawley rats (200-300 g) were perfused with Krebs-Henseleit bicarbonate buffer containing the drug (50-100 micrograms/mL) and glycine (0.5 or 5 mM) or glucose (5.5 mM) or bovine serum albumin (0.33%). Effluent samples over a 30-50 min interval were analyzed for salicylic acid and its metabolites (gentisic acid, salicyluric acid, and salicyl acyl and salicyl phenolic glucuronides). Effluent concentrations of salicylic acid did not differ from those in the perfusate, indicating that the liver is not a site for the metabolism of this drug. Hepatic uptake studies are needed to confirm this finding.

Irinotecan (CPT-11) is a semisynthetic derivative of camptothecine that has proved activity in the treatment of colorectal carcinoma. The metabolites identiยฎed in humans include SN-38, SN-38 glucuronide, and several CYP3A-derived metabolites. We have studied the hepatic extraction, metabolism, and b

## Abstract The __p__โ€coumaric acid, a phenolic acid, occurs in several plant species and, consequently, in many foods and beverages of vegetable origin. Its antioxidant activity is well documented, but there is also a single report about an inhibitory action on the monocarboxylate carrier, which o

The scope of the present work was to investigate the metabolism and the passage of octanoate from albumin into the phospholipid bilayer of the plasma membrane and from thence into the cell space. The experiments were done in the isolated perfused rat liver with infusions of albumin and octanoate at
