Adsorption of benzimidazole, 2-methylbenzimidazole and 2-aminobenzimidazole on mild steel in 3.5 NaCl solution was studied using density function theory DFT calculations. In this regard, charge transfer resistance Rct and double layer capacitance Cdl obtained by electrochemical impedance spectroscopy EIS were used to calculate surface coverage and to build prediction models. When prediction mod...

A wide variety of chiral succinimides have been prepared in high yields and enantioselectivities by an asymmetric conjugate addition of 1,3-dicarbonyl compounds to maleimides under very mild reaction conditions using the bifunctional benzimidazole-derived organocatalyst 5f. Computational and NMR studies support the hydrogen-bonding activation role of the catalyst and the origin of the stereosel...

OBJECTIVES Clinical resistance to the currently recommended extended-spectrum cephalosporins (ESCs), the last remaining options for empirical antimicrobial monotherapy of gonorrhoea globally, has been reported. New antimicrobials are essential to avoid the emergence of untreatable gonorrhoea. We have investigated the in vitro activity of a novel dual bacterial topoisomerase inhibitor of the ATP...

New drugs to treat drug-resistant tuberculosis are urgently needed. Extensively drug-resistant and probably the totally drug-resistant tuberculosis strains are resistant to fluoroquinolones like moxifloxacin, which target gyrase A, and most people infected with these strains die within a year. In this study, we found that a novel aminobenzimidazole, VXc-486, which targets gyrase B, potently inh...

A major source of uncertainty when assessing the human health and environmental risks of chemicals is the paucity of experimental information on the metabolic and (bio)degradation pathways of parent compounds and the toxicological properties of their metabolites and (bio)degradation products. Taking into account animal welfare and cost-effectiveness considerations, the only practical means of o...
