[Metabolic N- and S-oxygenation of dokloxytepin in vitro].

Dokloxytepin in the medium of the induced monooxygenase system of the microsomal fraction of the liver of the rat, rabbit and mice is metabolized into three metabolites: two identical, i.e., N-oxide and 5-sulfoxide, and a third different one. In the rat and rabbit it is the hitherto unknown metabolite M1, and in the mouse S,N-dioxide of dokloxytepin. The metabolites were identified by thin-layer chromatography by comparing with synthetic standards.
