          Abstract

          Electrospray ionization in the positive ion mode and high resolution and high accuracy tandem mass spectrometry performed in a hybrid quadrupole time-of-flight mass spectrometer were used to investigate the dissociation chemistry of the intact molecules of two most widely used antimalarial drugs: artemether and lumefantrine. The dissociation pathways of their cationized and protonated forms were rationalized based on high accuracy mass measurements and isotopic distributions. The obtained results should benefit LC-MS/MS monitoring and quantitation by mass spectrometry of the artemether and lumefantrine molecules, as well as of new derivatives or other structurally related antimalarial drugs.

          Ionização por electrospray no modo de íons positivos, e espectrometria de massas de alta resolução e exatidão, e em tandem, realizadas em espectrômetro de massas híbrido quadrupolo e tempo de vôo, foram utilizadas para investigar a dissociação química das moléculas intactas dos dois antimaláricos mais amplamente utilizados: artemeter e lumefantrina. As rotas de dissociação das formas cationizadas e protonadas foram claramente estabelecidas via determinações de massas de alta resolução e distribuição isotópica. Os resultados obtidos podem auxiliar a monitorização e a quantificação de artemeter e lumefantrina por LC-MS/MS, assim como de novos derivados ou outros fármacos antimaláricos estruturalmente relacionados.
