The metabolism of the antiepileptic mesoionic didehydro-4-methyl-5-phenyl-1,3,4-thiadiazolidine-2-thione (LU 2443) was investigated after p.o. application in rats. The main metabolite was benzoic acid, besides the unchanged material and hippuric acid the spasmodically compounds N-methyl-benzamide and mesionic didehydro-4-methyl-5-phenyl-1,3,4-thiadiazolidine-2-one were detectable. In-vitro experiments could be demonstrated that LU 2443 was not demethylated by biochemical oxidation, and LU 2443 was also very stable against metabolizing influences by enteric bacteria.
