The 1-phenyl-3-methyl-5-pyrazolone (PMP) derivatives of monosaccharides, maltooligosaccharides, and oligosaccharides enzymatically released from asparagine-linked sites in ribonuclease B and fetuin have been investigated using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).

Cardiolipins (CL) are mitochondria specific lipids. They play a critical role in ATP synthesis mediated by oxidative phosphorylation. Abnormal CL distribution is associated with several disease states. MALDI-MS and MALDI-MS/MS were used to demonstrate in situ analysis and characterization of
MALDI mass spectrometry in the solution of some forensic problems.

A new, selective, straightforward and general method for preparation of highly functionalized coronands or spiro derivatives bearing 1,2-dihydroxyacetophenone unit, under conventional conditions and ultrasonic irradiation, is reported. The reaction setup involves only one step, acylation of an α-chloro-3,4-dihydroxyacetophenone with phthaloyl

Rapid communications in mass spectrometry : RCM, 10(5), 529-536 (1996-01-01)
Several peptides were shown to undergo fragmentation during matrix-assisted laser desorption/ionization time-of-flight mass spectrometry to a degree which complicated their analysis using alpha-cyano-4-hydroxycinnamic acid (CHCA) as a matrix, even at threshold laser irradiance. These peptides included synthetic peptides, peptides isolated
