Overlay of the 5,6-fused bicyclic heteroaromatic scaffolds (7 – 12) crystal structures with potent N-benzyl-2,7-dimethyl-imidazo[1,2-a]pyridine-3-carboxamide (1). Legend. 1a – red, 1b – light pink, 7 – green, 8 – yellow, 9a – light orange, 9b – orange, 10 – blue, 11 – turquoise, 12 – magenta. Hydrogen atoms omitted for clarity. The nine atoms of 5,6-fused bicycle were used as template mapping atoms.
