A one-pot, two-step synthesis of imidazo[1,2-a]benzimidazoles has been achieved by a three-component reaction of 2-aminobenzimidazoles with an aromatic aldehyde and an isocyanide. The reaction involving condensation of 2-aminobenzimidazole with an aldehyde is run under microwave activation to generate an imine

The hydrolysis of a choline carbonate through a metal-free, enzyme-like mechanism has been achieved using a 2-aminobenzimidazole-based deep cavitand as catalyst. The supramolecular catalysis involves three steps: host-guest binding, carbamoylation and enzyme-like hydrolysis. Interestingly the rate-determining step proceeds through a

Dysregulation of NF-kappaB activity contributes to many autoimmune and inflammatory diseases. At least nine pathways for NF-kappaB activation have been identified, most of which converge on the IkappaB kinases (IKKs). Although IKKs represent logical targets for potential drug discovery, chemical

A novel series of non-imidazole H(3)-receptor antagonists was developed, by chemical modification of a potent lead H(3)-antagonist composed by an imidazole ring connected through an alkyl spacer to a 2-aminobenzimidazole moiety (e.g., 2-[[3-[4(5)-imidazolyl]propyl]amino]benzimidazole), previously reported by our research group. We

RNA cleaving tris(2-aminobenzimidazoles) have been attached to DNA oligonucleotides via disulfide or amide bonds. The resulting conjugates are effective organocatalytic nucleases showing substrate and site selectivity as well as saturation kinetics. The benzimidazole conjugates also degrade enantiomeric RNA.
