As a part of ongoing studies in developing new anticancer agents, novel 1,2-dihydropyridine 4, thienopyridine 5, isoquinolines 6-20, acrylamide 21, thiazolidine 22, thiazoles 23-29 and thiophenes 33-35 bearing a biologically active quinoline nucleus were synthesized. The structure of newly synthesized compounds was confirmed on the basis of elemental(More)
BACKGROUND Several edible plants are used in Kingdom of Saudi Arabia since early time to control microbial infections. In the present study, twenty-four Saudi Arabian medicinal plants d according to traditionally used were select and investigated for the antimicrobial activities. MATERIALS AND METHODS This study was designed at evaluating the(More)
An array of some new N-(substituted)-2-((4-oxo-3-(4-sulfamoylphenyl)-3,4-dihydrobenzo[g]quinazolin-2-yl)thio)acetamide 5-19 were synthesized from the starting compound 4-(2-mercapto-4-oxobenzo[g]quinazolin-3(4H)-yl)benzenesulfonamide 4, to be assessed for their cytotoxic activity against A549 lung cancer cell line and to determine their inhibitory effect on(More)
In the title compound, C(16)H(12)F(3)N(3)O(2)S·0.47C(2)H(5)OH·0.53CH(3)OH, the quinoline ring system is approximately planar, with a maximum deviation of 0.035 (3) Å, and makes a dihedral angle of 52.67 (9)° with the benzene ring. The F atoms of the -CF(3) group are disordered over two orientations, with refined site occupancies of 0.56 (2) and 0.44 (2). A(More)
Targeting EGFR has proven to be beneficial in the treatment of several types of solid tumours. So, a series of novel 2-(4-oxo-3-(4-sulfamoylphenyl)-3,4-dihydrobenzo[g]quinazolin-2-ylthio)-N-substituted acetamide 5-19 were synthesised from the starting material 4-(2-mercapto-4-oxobenzo[g]quinazolin-3(4H)-yl) benzenesulfonamide 4, to be evaluated as dual(More)
Novel sulfonamides 3-19 with a biologically active 3,4-dimethoxyphenyl moiety were designed and synthesized. The structures of the synthesized compounds were established using elemental analyses, IR, 1H-NMR, 13C-NMR spectral data and mass spectroscopy. All the synthesized compounds were evaluated for their in vitro anticancer activity against four cancer(More)
BACKGROUND Quinoline derivatives have diverse biological activities including anticancer activity. On the other hand, many sulfonamide derivatives exhibited good cytotoxic activity. Hybrids of both moieties may present novel anticancer agents. RESULTS Chloroquinoline incorporating a biologically active benzene-sulfonamide moieties 5-21 and diarylsulfone(More)
