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

4-Methylumbelliferyl sulfate (4MUS), a polar metabolite of 4-methylumbelliferone (4MU), is known to undergo desulfation and participate in futile cycling with 4MU. Unusual parabolic or increasing profiles of the steady-state extraction ratio (Ess) of 4MUS with respect to concentration in rat

Sulf-1 and Sulf-2 are novel extracellular sulfatases that act on internal glucosamine 6-O-sulfate modifications within heparan sulfate proteoglycans and regulate their interactions with various signaling molecules, including Wnt ligands. Although the Sulfs are multidomain proteins, there is limited information available
