New complexes of peroxidases with hydroxamic acids, hydrazides, and amides.
Horseradish peroxidase forms spectroscopically distinct, reversible complexes with hydroxamic acids (R-CONHOH), hydrazides (RCO-NHNH2), amides (RCONH2), and oc-hydroxyketones (RCO--CHsOH). Binding of these compounds to the enzyme depends on the polar and steric character of R and the hydrogen bonding capacity of-COX-Y (X-Y = NH-OH, NH-NH,, NH-H, CH,OH). Hydroxamate anions and hydrazide cations ...
متن کاملManganese catalysed sulfenylation of N-methyl amides with arenesulfonyl hydrazides.
A convenient oxidative sulfenylation method for the formation of various sulfenyl amides has been reported. Arenesulfonyl hydrazine as a sulfur source in the presence of a manganese salt can activate the sp(3) C-H bond of N-methyl amides through a free-radical pathway using di-tert-butyl peroxide (DTBP).
متن کاملAnalysis of hydroxamic acids and hydrazides; preparation and properties of dinitrophenyl derivatives of hydroxamic acids, oximes, hydrazides, and hydrazones.
The cleavage of gelatin to smaller molecular units by aqueous hydroxylamine or hydrazine under relatively mild conditions of temperature and pH has suggested the existence of “ester-like” or imide linkages in this protein (1). The amide bonds of gelatin were cleaved only to a minor extent and could not account for the large change in molecular weight. It is known, however, that prolonged treatm...
متن کاملThe fate of certain organic acids and amides in the rabbit; nitrobenzoic acids and amides.
Studies in vitro (Bray, James, Ryman & Thorpe, 1948a) have shown that rabbit-liver extracts are able to hydrolyze all three nitrobenzamides. The para isomer is most readily attacked, the average hydrolysis being 82 %; under the same conditions the meta and ortho isomers are hydrolyzed to the extent of 31 and 23 %, respectively. It was, therefore, of interest to study the metabolism of these com...
متن کاملThe Rationale behind the Decisions
The first was that there was no explicit power in the Convention to derogate: see paragraph 71. The absence of an explicit power of course does not necessarily mean that a power could not be implied into the Convention. Although the Court did not address the question of implication, the second reason for rejecting the derogation demonstrates why it would not have been able do so: such a power w...
