Derivatization of fatty alcohol ethoxylate non-ionic surfactants using 2-sulfobenzoic anhydride for characterization by liquid chromatography/mass spectrometry.

Chengli Zu et al.

Rapid communications in mass spectrometry : RCM, 24(1), 120-128 (2009-12-10)

A derivatization procedure has been developed for the improved characterization of fatty alcohol ethoxylate non-ionic surfactants by liquid chromatography/mass spectrometry. The end hydroxyl group of each surfactant species was converted into an oxycarbonylbenzene-2-sulfonic acid group with 2-sulfobenzoic anhydride under mild

Interface-mediated inactivation of pancreatic lipase by a water-reactive compound: 2-sulfobenzoic cyclic anhydride.

A Moulin et al.

Biochemistry, 28(15), 6340-6346 (1989-07-25)

2-Sulfobenzoic cyclic anhydride (SBA) rapidly and selectively inactivates porcine pancreatic lipase (PPL) only when added during the hydrolysis of an emulsified ester such as tributyrin or dodecyl acetate. The present data suggest that the inactivation of PPL occurs preferentially at

De novo sequencing of two new cyclic theta-defensins from baboon (Papio hamadryas) leukocytes by matrix-assisted laser desorption/ionization mass spectrometry.

Christin Stegemann et al.

Rapid communications in mass spectrometry : RCM, 24(5), 599-604 (2010-02-16)

Two cyclic theta-defensin peptides were isolated from leukocytes of the hamadryas baboon, Papio hamadryas, and purified to homogeneity by gel electrophoresis and reversed-phase high-performance liquid chromatography. Both peptides had high in vitro activity against Escherichia coli, Listeria monocytogenes, methicillin-resistant Staphylococcus
