Results Uptake and compartmentation of fluorescent anions in the absence of probenecid When epidermal strips were floated on aqueous solutions of the probes FITC, CF, SR, LYCH and CB, the dyes entered the central vacuole of the epidermal cells, a distinctive feature in all cases being a lack of staining of either the cytoplasm or the nucleus during accumulation e.g. see Fig. 2A, F ; . Cytoplasmic streaming was unaffected by the accumulation of the dyes. The permeant FITC molecule was accumulated at a much greater rate than the other more impermeant probes, showing a rapid initial uptake or binding 0-2 h ; followed by a more gradual linear uptake phase Fig. 3 ; . In the case of the probes SR, CB and LYCH, uptake was approximately an order of. 98% bound ; Meijer et al., 1977 ; and is a substrate for both the sinusoidal and canalicular organic anion transporter systems Oude Elferink et al., 1995 ; . Therefore, to identify the mechanism by which DBSP alters the disposition of GG, the potential competition for perfusate albumin binding sites and hepatic transport systems should be considered. Both GG and gemfibrozil were bound to albumin, consistent with many findings for carboxylic acid drugs and their glucuronides such as zomepirac Ojingwa et al., 1994b ; , tolmetin Ojingwa et al., 1994b ; , ketoprofen Hayball et al., 1992 ; , carprofen Iwakawa et al., 1990 ; , and fenoprofen Bischer et al., 1995 ; . In the present study, it is clear that gemfibrozil had a higher affinity for albumin than did its glucuronide conjugate. Therefore, given the molar ratios of ligand to binding protein, it is not unexpected that gemfibrozil exhibited nonlinear binding to albumin. DBSP caused a significant increase in the fu of GG but had no effect on the binding of gemfibrozil. The different effects of DBSP on the binding of the two ligands to albumin are consistent with the lower affinity of GG for albumin compared with that of gemfibrozil. However, the result is also consistent with the presence of different binding sites on albumin for gemfibrozil and its glucuronide. Different binding sites on albumin have been reported for carprofen enantiomers and their acyl glucuronides Iwakawa et al., 1990 ; , whereas fenoprofen Bischer et al., 1995 ; , zomepirac Ojingwa et al., 1994b ; , and tolmetin Ojingwa et al., 1994b ; share common binding sites with their respective acyl glucuronides. With a hepatic extraction ratio of 0.3, GG may be classified as a low clearance compound, and thus its hepatic clearance should be dependent on fu and CLint Wilkinson and Shand, 1975 ; . The 42% lower CL of GG the combined result of an increase in fu counteracted by a larger decrease in CLint. As discussed earlier, DBSP is unlikely to alter intrinsic metabolic activity; therefore, the observed reduction in CLint is likely to be due to an interaction with DBSP at the level of hepatic membrane transport. A number of carrier-mediated transport systems have been identified for organic anions at both the sinusoidal and canalicular membranes of hepatocytes. At the sinusoidal membrane, a sodium-dependent transport system Hagenbuch et al., 1990 ; and a sodium-independent transport system have been identified for the uptake of bile acids into the liver Jacquemin et al., 1994 ; , the latter system of which also mediates uptake of nonbile acid organic anions such as DBSP and BSP Oude Elferink et al., 1995 ; . In addition, at least three other putative carrier-proteins have been proposed to mediate the sinusoidal uptake of nonbile acid organic anions, including DBSP, BSP, and bilirubin Groothuis and Meijer, 1996 ; . Little information is available on the efflux of compounds from the liver across the sinusoidal membrane into the systemic circulation. However, the inhibition of sinusoidal efflux of morphine-3-glucuronide by probenecid Evans et al., 1995 ; and of harmol sulfate by DBSP De Vries et al., 1985 ; indicates that carrier-mediated efflux systems are present at the sinusoidal membrane. Transporters at the canalicular membrane include an ATP-dependent bile acid transporter and the ATP-dependent canalicular multispecific organic anion transporter rat cmoat or human cMOAT ; , which exports nonbile acid organic anions such as cystenyl leukotriene, DBSP, bilirubin glucuronide conjugates, and DNP-SG Keppler and Arias, 1997 ; . As discussed earlier, the.
