Metabolism of phenothiazines: identification of N-oxygenated products by gas chromatography and mass spectrometry. 1975

E E Essien, and D A Cowan, and A H Beckett

The solid inlet mass spectra of the N-oxide and N-oxide sulphoxide metabolites of promazine, chlorpromazine and methotrimeprazine have been determined at different temperatures and compared with the mass spectra of the main thermolytic product of the N-oxides and N-oxide sulphoxides obtained during combined gas chromatography-mass spectrometry. Diagnostic ions were produced by direct insertion of the compounds at ambient temperature into the mass spectrometer. These ions distinguish the N-oxides of arylalkyl tertiary amines from the N-oxygenated derivatives of primary and secondary arylalkylamines.

UI	MeSH Term	Description	Entries
D008728	Methotrimeprazine	A phenothiazine with pharmacological activity similar to that of both CHLORPROMAZINE and PROMETHAZINE. It has the histamine-antagonist properties of the antihistamines together with CENTRAL NERVOUS SYSTEM effects resembling those of chlorpromazine. (From Martindale, The Extra Pharmacopoeia, 30th ed, p604)	Levomeprazin,Levomepromazine,Levopromazine,Tisercin,Tizercine,Tizertsin
D010640	Phenothiazines	Compounds containing dibenzo-1,4-thiazine. Some of them are neuroactive.
D011395	Promazine	A phenothiazine with actions similar to CHLORPROMAZINE but with less antipsychotic activity. It is primarily used in short-term treatment of disturbed behavior and as an antiemetic.	Promazine Hydrochloride,Protactyl,Sinophenin,Sparine,Hydrochloride, Promazine
D002746	Chlorpromazine	The prototypical phenothiazine antipsychotic drug. Like the other drugs in this class chlorpromazine's antipsychotic actions are thought to be due to long-term adaptation by the brain to blocking DOPAMINE RECEPTORS. Chlorpromazine has several other actions and therapeutic uses, including as an antiemetic and in the treatment of intractable hiccup.

D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D002855	Chromatography, Thin Layer	Chromatography on thin layers of adsorbents rather than in columns. The adsorbent can be alumina, silica gel, silicates, charcoals, or cellulose.
