چکیده
The benzyl residue in the title compound, C(21)H(23)N(5)·0.5H(2)O, is oriented at a dihedral angle of 83.8 (3)° towards the 1,6-dihydro-imidazo[4,5-d]pyrrolo-[2,3-b]pyridine system. The piperidine ring adopts a chair conformation with the cis substituents displaying a torsion angle of -45.91 (16)°. In the crystal, mol-ecules are accumulated as racemic dimers by two inter-molecular hydrogen bonds between the pyrrolo-pyridine systems. Another hydrogen bond is formed between the imidazole ring and the cocrystallized water mol-ecule, which is located on a twofold rotation axis.

متن کاملDesign and One-Pot Synthesis of (1H, 3H) Imidazo[4,5-b] Pyridines: Novel Therapeutic Agents Against M. Tuberculosis
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...
