HIGH-PERFORMANCE LIQUID CHROMATOGRAPHIC ANALYSIS OF SULFUR MUSTARD REACTION WITH AMINO ACIDS AND PROTEINS
The interaction of sulfur mustard with aminoacids and proteins has been investigated in this study. Rats were injected with sublethal doses of sulfur mustard subcutaneously and intraperitoneally. At different time intervals, plasma and urine samples were collected. The binding affinity of sulfur mustard with urinary and plasma proteins and enzymes was studied for the first time using non-i...
متن کاملPhosphotungstic Acidcatalyzed Strecker Three-Component Reaction of Amino Acids, Aldehydes, and Trimethylsilyl Cyanide
A simple and efficient one-pot, three-component Strecker reaction of protected amino acids, aromatic aldehydes, and trimethylsilyl cyanide has been developed for the synthesis of chiral α-amino nitriles. The reaction was carried out in the presence of catalytic amount of phosphotungstic acid (H3[P(W3O10)4]) as an environmentally friendly cata...
متن کاملEqual reaction rates for all recombination pathways
Formal collision theory indicates that the absolute termolecular recombination reaction rate can be expressed in a form associated either with direct or indirect mechanisms for the recombination. Moreover, the same exact rate constant can be calculated using either of the four mechanisms. These results are to be contrasted to the rate constants standardly calculated by approximate methods. © 19...
متن کاملThe reaction of aminoacylase with chloromethylketone analogs of amino acids.
1. Aminoacylase is irreversibly inactivated by the chloromethylketone analogs of benzyloxy-carobonyl-L-alanine, L-alanine, L-leucine, L-aspartic acid (beta), tosyl-L-phenylalanine and L-leucyl-L-alanine. The kinetics of the inactivation of the enzyme by the halo-methylketones were investigated. 2. Leucyl-and alanyl chloromethylketone inactivate the enzyme by blocking of 4 SH groups. Experiments...
