چکیده
In the mol-ecule of the title compound, C(12)H(15)BrN(4)O(2), the imidazole and pyridine rings are strictly coplanar [maximum deviation 0.006 (3) Å]. In the crystal structure, mol-ecules are linked into chains running parallel to the a axis by inter-molecular N-H⋯O hydrogen bonds. Centrosymmetrically related chains are further connected by N-H⋯N hydrogen-bonding inter-actions to form a two-dimensional layer structure parallel to the ab plane.

In the mol-ecule of the title compound, C(12)H(12)BrN(3)O, the fused-ring system is essentially planar, the largest deviation from the mean plane being 0.0148 (3) Å. The two allyl groups are nearly perpendicular to the imidazo[4,5-b]pyridine plane [C-C-N-C torsion angles of 81.6 (4) and -77.2 (4)°] and point in the same direction. The planes through the atoms forming each allyl group are nearly...

The title compound, C(7)H(6)BrN(3)O, was obtained from the reaction of 6-bromo-1H-imidazo[4,5-b]pyridin-2(3H)-one with methyl iodide. All non-H atoms lie in a common plane [r.m.s deviation = 0.017 (1) Å]. The amino group is a hydrogen-bond donor to the carbonyl group of an inversion-related mol-ecule, the pair of hydrogen bonds giving rise to a hydrogen-bonded dimer.

Prevalence to the various biological activities of imidazo[4,5-b] pyridine nucleus has promoted us for an attempt of one pot synthesis of (1H, 3H) imidazo [4,5-b] pyridines (desazopurines) as inhibitors of Lumazine synthase in M. tuberculosis (PDB 2C92). Major advantage of Lumazine synthase enzyme behind consideration as target protein in docking study is its absence in mammalian cell but prese...

In the title compound, C12H8BrN3O, the 4-bromo-phenol ring is coplanar with the planar imidazo[4,5-b]pyridine moiety (r.m.s deviation = 0.015 Å), making a dihedral angle of 1.8 (2)°. There is an intra-molecular O-H⋯N hydrogen bond forming an S(6) ring motif. In the crystal, mol-ecules are linked via N-H⋯N and O-H⋯Br hydrogen bonds, forming undulating sheets parallel to (10-2). The sheets are li...
