Kinetics and Mechanism of Hydrolysis of Benzimidazolylcarbamates [PDF]

, 2007
Synthesis of new 2-aminobenzimidazole-1-carbamates was accomplished by carbamoylation of 2-aminobenzimidazole using different substituted phenyl chloroformates. The aqueous hydrolysis of the new compounds was examined in the pH range 1-13 at 25 oC.

Accessing New Phenanthroline-Oxazine Scaffolds as Copper-Dependent DNA Damaging Probes. [PDF]

Chembiochem
New phenanthroline–oxazine ligands derived from natural amino acids are synthesized through an optimized, predictive strategy. When coordinated to copper, these scaffolds display tunable DNA binding, groove selectivity, and oxidative cleavage activity, revealing clear structure activity relationships and expanding the toolbox of copper‐dependent ...

Microsomal superoxide anion production and NADPH-oxidation in a series of 22 aziridinylbenzoquinones [PDF]

, 1989
Several 2,5-bis(1-aziridinyl)-1,4-benzoquinones (BABQs) can be activated to alkylating species by reduction of the quinone moiety. On the other hand, cytotoxicity of these compounds can be induced by redox cycling.

Finite Larmor Radius Effects on Weakly Magnetized, Dilute Plasmas [PDF]

, 2010
We investigate the stability properties of a hot, dilute and differentially rotating weakly magnetized plasma which is believed to be found in the interstellar medium of galaxies and protogalaxies and in the low-density accretion flows around some giant ...

The kinetics of the reaction of 6-substituted nicotinic acids and some p-substituted benzoic acids with diazodiphenylmethane in various alcohols [PDF]

Journal of the Serbian Chemical Society, 2000
Rate constants have been determined for the reactions of diazodiphenylmethane with a number of 6-substituted nicotinic acids and p-substituted benzoic acids in twelve alcohols. A comparative study was used to evaluate and compare the Hammett r values and

Substituent effect on IR, 1H and 13C NMR spectral data in n-(substituted phenyl)-2-cyanoacetamides: A correlation study [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2013
Linear free energy relationships (LFER) were applied to the IR, 1H and 13C NMR spectral data of N-(substituted phenyl)-2-cyanoacetamides. A variety of substituents were employed for phenyl substitution and fairly good correlations were obtained using ...

A kinetic and theoretical study of the borate catalysed reactions of hydrogen peroxide: the role of dioxaborirane as the catalytic intermediate for a wide range of substrates [PDF]

, 2012
Our recent work has provided new insights into the equilibria and species that exist in aqueous solution at different pHs for the boric acid – hydrogen peroxide system, and the role of these species in oxidation reactions. Most recently, (M. C.
