Fragmentation of a series of cyclic dipeptides in fast-atom bombardment mass spectrometry. 1995

M Henczi, and D F Weaver

Department of Chemistry, Queen's University, Kingston, Canada.

The positive-ion mass spectra of a series of cyclic dipeptides have been obtained by fast-atom bombardment mass spectrometry. The protonated molecules were mass selected and their collision-induced dissociations were analysed by tandem mass spectrometry. This approach allowed an easy structural characterization of the above mentioned class of compounds for further pharmacological studies.

D016339	Spectrometry, Mass, Fast Atom Bombardment	A mass spectrometric technique that is used for the analysis of a wide range of biomolecules, such as glycoalkaloids, glycoproteins, polysaccharides, and peptides. Positive and negative fast atom bombardment spectra are recorded on a mass spectrometer fitted with an atom gun with xenon as the customary beam. The mass spectra obtained contain molecular weight recognition as well as sequence information.
