Abstract

An expeditious one-pot, ligand-free, Pd(OAc)2-catalyzed, three-component reaction for the synthesis of 2,3-diarylimidazo[1,2-a]pyridines was developed under microwave irradiation. With the high availability of commercial reagents and great efficiency in expanding molecule diversity, this methodology is superior to the existing procedures for the synthesis of 2,3-diarylimidazo[1,2-a]pyridines analogues.

AutoDock Vina: improving the speed and accuracy of docking with a new scoring function, efficient optimization, and multithreading.

Oleg Trott, Arthur Olson (2010)

AutoDock Vina, a new program for molecular docking and virtual screening, is presented. AutoDock Vina achieves an approximately two orders of magnitude speed-up compared with the molecular docking software previously developed in our lab (AutoDock 4), while also significantly improving the accuracy of the binding mode predictions, judging by our tests on the training set used in AutoDock 4 development. Further speed-up is achieved from parallelism, by using multithreading on multicore machines. AutoDock Vina automatically calculates the grid maps and clusters the results in a way transparent to the user. Copyright 2009 Wiley Periodicals, Inc.

Recent progress in the pharmacology of imidazo[1,2-a]pyridines.

Cécile Enguehard-Gueiffier, Alain Gueiffier (2007)

Imidazo[1,2-a]pyridine is a bicyclic system with a bridgehead nitrogen atom, of growing interest in medicinal chemistry. The paper deals with the recent progress realised in the comprehension of the pharmacological properties of this scaffold. From the many imidazo[1,2-a]pyridine analogues described in the literature, those discussed herein will be presented in three parts concerning first the enzyme inhibitors, then the receptor ligands and finally the anti-infectious agents.

Design, synthesis and in vitro antimicrobial evaluation of novel Imidazo[1,2-a]pyridine and imidazo[2,1-b][1,3]benzothiazole motifs.

Taleb Al-Tel, Raed A. Al-Qawasmeh, Rania Zaarour (2011)

New antimicrobial agents, imidazo[1,2-a]pyridine and imidazo[2,1-b][1,3]benzothiazole, have been synthesized. Their antimicrobial activities were conducted against various Gram-positive, Gram-negative bacteria and fungi. Compounds 6c, 7a, 10b, 11a, 12b, 14a, 14b, 15a and 15b, exerted strong inhibition of the investigated bacterial and fungal strains compared to control antibiotics amoxicillin and cefixime and the antifungal agent fluconazole. Results from this study showed that the nature of the substituents on the armed aryl groups determines the extent of the activity of the fused imidazopyridine and/or imidazobenzothiazole derivatives. Preliminary structure-activity observations revealed that bromo-fluoro substituents enhanced the antimicrobial activity significantly compared to other substituents.
