New derivatives of imidazo[4,5-b]pyridine and 9H-dipyrido-[1,2-a:3',2'-d]imidazole were synthesized. Antibacterial activity against Mycobacterium tuberculosis of selected compounds was determined. These data were combined with the corresponding bioactivity data previously generated for two other series of imidazo[4,5-b]pyridines. Analysis of Quantitative Structure-Activity Relationships

A hit generation and exploration approach led to the discovery of 31 (2-(4-(6-chloro-2-(4-(dimethylamino)phenyl)-3H-imidazo[4,5-b]pyridin-7-yl)piperazin-1-yl)-N-(thiazol-2-yl)acetamide), a potent, novel inhibitor of Aurora-A, Aurora-B and Aurora-C kinases with IC(50) values of 0.042, 0.198 and 0.227microM, respectively. Compound 31 inhibits cell proliferation and has good
