A new series of 2-thiophenoxyquinoline-based penta-substituted pyridine derivatives, 6(a–r), has been synthesized by base-catalyzed cyclocondensation reaction through multi-component reaction (MCR) approach. In vitro antimicrobial activity of the synthesized compounds was investigated against a representative panel of pathogenic strains, specifically three Gram-positive bacteria (Streptococcus pneumoniae

A series of new Schiff's base derivatives 4a-x bearing 2-thiophenoxyquinoline nucleus have been designed and synthesized by reaction of 2-thiophenoxyquinoline-3-carbaldehydes 2a-d with various benzohydrazides 3a-f in the presence of Ni(NO3)(2)center dot 6H(2)O as a catalyst. In vitro antibacterial screening was carried out against two Gram-positive bacteria (Bacillus subtilis ATCC 6633 and Staphylococcus aureus ATCC 6538) and two Gram-negative bacteria (Escherichia coli ATCC 35218 and Pseudomonas aeruginosa ATCC 13525). Of the compounds studied, compound 4e showed chief activity (MIC = 3.13 mu g/mL) against S. aureus, and compounds 4p, 4k, and 4w were found to possess effective antibacterial activity against employed strains compared with standards used. The structures of Schiff's base derivatives were established by using various spectroscopic methods. A crystal structure of compound 4k has been determined by X-ray diffraction analysis.

A new series of 2-thiophenoxyquinolines based trifluoromethyl substituted N-aryl quinolone derivatives 8a-f and 9a-f have been synthesized via a one-pot multicomponent reaction. In vitro antimicrobial activity of the synthesized compounds was investigated against a representative panel of pathogenic strains. Compounds 8c, 9c and 9e exhibited comparable antimicrobial activity to first line drugs. (C) 2014 Manish P. Patel. Published by Elsevier B.V. on behalf of Chinese Chemical Society.

activities against two cancer cell lines A549 and Hep G2. Compound 9n (IC50 = 0.09 μM) against EGFR and (IC50 = 1.03 μM) against A549 kinase displayed the most potent inhibitory activity as compared to other member of the series. In the molecular modelling study, compound 9p was bound in to the active pocket of EGFR with two hydrogen bonds and one π-cation interactions having minimum binding energy ΔGb
