Mass spectrometric studies on peptides and proteins : conformations of Escherichia coli Thioredoxin and its alkylated adducts studied by hydrogen/deuterium exchange and HPLC-electrospray ionization mass spectrometry

Creator:: Kim, Moo-young
Abstract:: E. coli thioredoxin (TRX) was modified by the episulfonium ion derived from S-(2-chloroethyl)glutathione (CEG) or S-(2-chloroethyl)cysteine (CEC). The alkylation site was located at Cys-32, which was confirmed by tandem mass spectrometry. Two forms of native TRX, Oxi- and Red-TRX, and two modified TRXs, GS- and Cys-TRX, were examined by hydrogen/deuterium...

Photochemistry of some bromoarenes

Creator:: Jang, Jung-suk
Abstract:: The photodebromination of selected bromoarenes has been studied at 300 nm to determine the the possible mechanistic pathways leading to product. Irradiation of 4-bromobiphenyl (BpBr) at this wavelength leads to the product biphenyl. The quantum yield of intersystem crossing (0.98) and quenching studies with cis-1 ,3-pentadiene suggest that the reaction...

The heteroatom effect in intramolecular cyclizations of organoaluminum and -lithium compounds

Creator:: Smith, Michael James
Abstract:: Intramolecular cyclization of organometallic compounds represents a promising tool for synthesis in general. The use of strategically- placed heteroatoms in the cyclizing molecule can influence the stereochemistry and/or efficiency of an organometallic cyclization while providing for functionality in the cyclic product. The work described herein first concerns cyclizations of organolithiums....

A study of the chemistry of diisopropyl-, cyclopropylisopropyl-, and dicyclopropylcarbene

Creator:: Wuerch, Stephen E.
Abstract:: The effect of the conjugation with cyclopropyl rings on the activation parameters for the formation of carbenes from the corresponding diazo compounds was investigated using diisopropylcarbene (46), cyclopropyl-isopropylcarbene (47), and dicyclopropylcarbene (48). Each of these three carbenes was generated by the thermolysis of the parent benzenesulfonylhydrazone potassium salts using DMSO...

Mechanistic studies of polyhalogenated benzenes

Creator:: Herbelin, Sharon Maley
Abstract:: Polyhalogenated benzenes have been analyzed by standard electron capture chemical ionization mass spectrometry (ECCI/MS), and electron monochromator mass spectrometer (EM/MS) systems. The EM/MS experiments distinguished electronegative compounds (especially isomers) by transient negative ions (TNIs) of the same mass but differing energies and/or the formation of distinct TNIs of different masses...
