The coordination chemistry of transition metal complexes has been progressing at a tremendous pace. These complexes were finding use in the field of homogeneous catalysis, analytical chemistry and biological system. The presence of thiocyanto group in mixed ligand coordinated complexes of transition metal was reported to have an ability to influence the biochemical behaviour of the complexes. C...

A ratiometric fluorescent probe for hypoxanthine (Hx) detection was established based on the mimic enzyme and fluorescence characteristics of cobalt-doped graphite-phase carbon nitride (Co doped g-C3N4). In addition to emitting strong fluorescence, peroxidase activity Co g-C3N4 can catalyze reaction O-phenylenediamine H2O2 produc...

Sharma Dept. of Pharmaceutical Sciences, Dr.Hari Singh Gour University Sagar (M.P) 470003 India Department of Chemistry Yadhunath Mahavidyalya Bhind (M.P) 477001 India Email: [email protected] Abstract In this study we have synthesized some Benzimidazole derivatives (2-{6Chloro-5-nitro-1-[2-(1H-tetrazol-5-yl) biphenyl-4-ylmethyl] 1Hbenzoimidazol-2-yl}-phenyl)-(Substituted-benzyl...

A bioassay for the possible carcinogenicity of technical-grade 4-chloro-o-phenylenediamine was conducted using Fischer 344 rats and B6C3F1 mice. 4-Chloro-o-phenylenediamine was administered in the feed, at either of two concentrations, to groups of 49 or 50 male and 50 female animals of each species. For male and female rats, the high and low time-weighted average dietary concentrations of 4-ch...

The rate of the degenerate isomerization of A^-hexafluoroisopropylidene-V,V-dimethyl-/?-phenylenediamine was measured by high-pressure F NMR spectroscopy in a viscous hydrocarbon, 2,4-dicyclohexyl-2-methylpentane. Pressure-induced retardations that cannot be rationalized within the framework of the transition state theory (TST) were observed, and it was concluded that the reaction was cast into...

A novel iron(III) complex [Fe(SF)](ClO(4))(3).2H(2)O; in which SF = N,N(0)-bis{5-[(triphenylphosphonium chloride)-methyl] salicylidene}-o-phenylenediamine) has been synthesized and characterized using different physicochemical methods. The binding of this complex with calf thymus (CT) DNA was investigated by circular dichroism, absorption studies, emission spectroscopy, voltammetric studies, an...
