In right-side out rat hepatic canalicular membrane vesicles glutathione disulfide (GSSG) inhibited the efflux of taurocholate approx. 70% in the presence or approx. 55% in the absence of a valinomycin-mediated K+ diffusion potential; maximal inhibition occurred at 5 mM GSSG. The inhibition by GSSG was abolished by dithioerythritol. Neither dithioerythritol alone nor GSH inhibited taurocholate efflux. S-(2,4-Dinitrophenyl) glutathione and N-ethylmaleimide showed intermediate inhibitory effects. © 1987.
