New antibacterial agents, pyrrolo[3,2-c]pyridine derivatives have been designed and synthesized. The structural considerations of the designed molecules were further supported by the docking study with GlcN-6-P synthase. The chemical structures of the new compounds were characterized by NMR, mass spectral analysis and elemental analysis. Single crystals of two compounds, C13H15N2Cl [6a] and C21H24N3OCl, CH4O [7c] were obtained allowing for structural analysis. [C13H15N2Cl] monoclinic, P2(1)/c, a = 9.9763(6) angstrom, b = 9.6777(6) angstrom, c = 13.3002(9) angstrom, beta = 106.459(7)degrees, V = 1231.47(14) angstrom(3), Z = 4, T = 173(2) K, mu(Cu K alpha) = 2.522 mm(-1), D-calc = 1.266 g/mm(3), 7124 reflections, 2404 unique (R-int= 0.0381), R-1 = 0.0420 (I > 2 sigma(I)) and wR(2) = 0.1254 (all data). [C21H24N3OCl, CH4O] triclinic, P-1, a = 10.1478(7) angstrom, b = 12.0945(8) angstrom, c = 18.3244(10) angstrom, alpha = 104.369(5)degrees, beta = 90.766(5)degrees, gamma = 99.23 5(6)degrees, V = 2147.1(2) angstrom(3), Z = 4, T = 1 73(2) K, mu(CU K alpha) = 1.744 mm(-1), D-calc = 1.243 g/mm(3), 14238 reflections, 8297 unique (R-int = 0.0330), R-1= 0.0578 (I> 2 sigma(1)) and wR(2) = 0.1773 (all data). The in vitro antimicrobial activities of the compounds were conducted against various Gram-negative, Gram-positive bacteria and fungi. Amongst the tested compounds 7e displayed promising antibacterial activity against Gram-positive bacteria Bacillus flexus compared to antibiotic Amoxicillin. (C) 2014 Elsevier B.V.
