comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولSynthesis Antimicrobial Activity and Chemotherapeutic Potential some Novel Benzimidazole Derivatives
Benzimidazole derivates play vital role in biological field such as antimicrobial, antiviral, antidiabetic, and anticancer activity. Therapeutic significance of these clinically useful drugs in treatment of microbial infections encouraged the development of some more potent and significant compounds. With the purpose of finding new chemical entities with enhanced antimicrobial activity, a serie...
متن کاملSynthesis of some benzimidazole derivatives endowed with 1,2,3-triazole as potential inhibitors of hepatitis C virus.
New derivatives of 2-thiobenzimidazole incorporating triazole moiety were synthesized, characterized and tested in vitro for antiviral activity against hepatitis C virus (HCV) and hepatitis B virus (HBV). Their cytotoxicity was determined by the reduction in the number of viable cell. All of the synthesized compounds are inactive against HBV and some showed activity against HCV. In particular, ...
متن کاملSynthesis and Evaluation of Selected Benzimidazole Derivatives as Potential Antimicrobial Agents.
A library of 53 benzimidazole derivatives, with substituents at positions 1, 2 and 5, were synthesized and screened against a series of reference strains of bacteria and fungi of medical relevance. The SAR analyses of the most promising results showed that the antimicrobial activity of the compounds depended on the substituents attached to the bicyclic heterocycle. In particular, some compounds...
متن کاملSynthesis, Characterization, and Biological Evaluation of Benzimidazole Derivatives as Potential Anxiolytics
The synthesized benzimidazoles compounds were prepared from the condensation reaction between o-Phenylenediamine and various carbonyl compounds, in the presence of ammonium chloride as a catalyst. Ammonium chloride is a commercial and environmentally benign catalyst. The yield of all benzimidazole derivatives was found to be in the range of 75 - 94%. The purity of the compounds was ascertained ...
