Abstract
The fate of oxisuran in the pig was studied with 14C-labeled drug to quantify its biotransformation and disposition. Despite interanimal differences, it was clear that the compound absorbed rapidly and biotransformed extensively to metabolites which were excreted principally in urine rather than in feces. Direct attacks upon oxisuran involved reduction to diastereo-isomeric oxisuran alcohol sulfoxides and oxidation to oxisuran sulfone. Subsequently, the oxisuran alcohol sulfoxides were reduced to a sulfide and oxidized to a sulfone. Phase II reactions appeared to be limited to sulfation of oxisuran alcohol sulfoxides and oxisuran alcohol sulfone. Pharmacokinetics were investigated for oxisuran and its metabolites.
