  Development of 1-aryl-3-furanyl/thienyl-imidazopyridine templates for inhibitors against hypoxia inducible factor (HIF)-1 transcriptional activity

  摘要：

  1,3-Disubstituted-imidazopyridines were designed for developing inhibitors against HIF-1 transcriptional activity. Designed compounds were rapidly synthesized from a key aromatic scaffold via microwave-assisted Suzuki-Miyaura coupling/C-H direct arylation sequence. Evaluation of ability to inhibit the hypoxia induced transcriptional activity of HIF-1 revealed that the compound 2i and 3a retained the same level of the inhibitory activity comparing with that of known inhibitor, YC-1 (1). Identified, readily accessible 1-aryl-3-furanyl/thienyl-imidazopyridine templates should be useful for future drug development. (C) 2016 Elsevier Ltd. All rights reserved.

  approach has been explored for regioselective C-1 thiocyanation of imidazo[1,5-a]pyridines. Reproducibility of the proposed methodology in the presence of diverse electron-donating and electron-withdrawing groups on the C-3 aryl ring and different heteroaryl and alkyl substituents at the C-3 position of the imidazo[1,5-a]pyridine nucleus widened the substrate scope. The proposed protocol is further reproducible

  A copper(I)-catalyzed direct transannulation of N-heteroaryl aldehydes or ketones with alkylamines via C-sp(3)-H amination has been achieved using molecular oxygen as a sole oxidant. N-Heteroarenes are employed as the amine source. This transformation provides a rapid and concise access to multifunctional imidazo[1,5-a]pyridines.
