Gas chromatography mass spectrometry studies on biologically important 8-aminoquinoline derivatives. 1978

J D Baty, and D A Price-Evans, and H M Gilles, and J Greaves

Several substituted 8-aminoquinolines related to known antimalarial drugs have been studied by gas chromatography mass spectrometry. 5,6-Dihydroxy-8-aminoquinoline, a possible metabolite of Primaquine, can be detected by single ion monitoring after conversion to a trimethylsilyl ether derivative. The mass spectra obtained in this study indicate that there are certain ions which are characteristic of the trimethylsilyl ethers of hydroxylated 8-aminoquinolines and 5,6-dimethoxy-8-aminoquinolines. These compounds should thus be amenable to analysis if they were produced during in vivo metabolism studies. Using selected ion monitoring the derivatized compounds can be detected at submicrogram levels.

UI	MeSH Term	Description	Entries
D011319	Primaquine	An aminoquinoline that is given by mouth to produce a radical cure and prevent relapse of vivax and ovale malarias following treatment with a blood schizontocide. It has also been used to prevent transmission of falciparum malaria by those returning to areas where there is a potential for re-introduction of malaria. Adverse effects include anemias and GI disturbances.

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.

D000634	Aminoquinolines	Quinolines substituted in any position by one or more amino groups.
D001711	Biotransformation	The chemical alteration of an exogenous substance by or in a biological system. The alteration may inactivate the compound or it may result in the production of an active metabolite of an inactive parent compound. The alterations may be divided into METABOLIC DETOXICATION, PHASE I and METABOLIC DETOXICATION, PHASE II.
D013058	Mass Spectrometry	An analytical method used in determining the identity of a chemical based on its mass using mass analyzers/mass spectrometers.
