Futile cycling between 4-methylumbelliferone and its sulfate and glucuronide conjugates was examined in the single-pass perfused rat liver preparation. The steady-state hepatic extraction ratio of 4-methylumbelliferone was found to be high (0.97) at a low input concentration of 0.005 mumol/L

A sensitive fluorometric assay was developed for alcohol sulfotransferase (AST). This was the first continuous fluorometric assay reported for AST. It used 3'-phosphoadenosine 5'-phosphosulfate regenerated from 3-phosphoadenosine 5'-phosphate by a recombinant phenol sulfotransferase (PST) using 4-methylumbelliferyl sulfate as the sulfuryl
