A non-redox dual inhibitor of both cyclooxygenase and 5-lipoxygenase, [2,2-dimethyl-6-(4-chlorophenyl)-7-phenyl-2,3-dihydro-1H-pyrrolizine-5- yl]-[2'-14C]-acetic acid (3, ML 3000), was synthesized as [14C]-labelled compound and administered orally to rats. Distribution of radioactivity was examined by use of whole-body autoradiography after administration of doses in the range 13.7-26.6 mg/kg. Highest tissue levels were detected in the lung, liver, kidney, heart and large and small intestine. 48 h after administration, 58.3% of the total radioactivity was found in the feces and 7.9% in the urine. The distribution of radioactivity in the tissue, time course of plasma concentration, urinary and fecal excretion as well as hydrolysis experiments with beta-glucuronidase suggest an enterohepatic circulation and metabolization to glucuronides.
