A series of 2-oxo-quinoline-3-Schiff-base derivatives (4a1-4n2) have been designed and synthesized as new antitumor agents. in vitro Antitumor activities were evaluated against four cancer cell lines including MGC80-3, BEL-7404, A549 and NCI-H460. Compounds 4a1, 4a2, 4c2, 4d1, 4d2 and 4l2 exhibited better inhibition activities than commercial antitumor drug 5-fluorouracil (5-fluorouracil, IC50 = 44 ±0.54 μM) on NCI-H460, with IC50 of 35.52 ± 0.86, 16.22 ± 0.71, 11.62 ± 0.52, 5.16 ± 0.37, 7.62 ± 0.46 and 7.66 ± 0.65 μM, respectively.

A series of 2-oxo-quinoline-3-carbaldehyde Schiff-base derivatives 4a 1-4n2 were designed and synthesized based on the 2-oxo-quinoline structure core as novel antioxidants. In vitro antioxidant activities of these compounds were evaluated and compared with commercial antioxidants ascorbic acid, BHT and BHA, employing DPPH assay, ABTS+ assay, O2- assay and OH assay. The results showed that IC50 of most compounds were lower than standard value 10 mg/mL, indicating good antioxidant activities of these compounds. In addition, in vitro antioxidant activities screening revealed that 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities of compounds 4b2, 4e 1, 4e2 and 4g2, 2,2′-azinobis-(3- ethylbenzthiazoline-6-sulphonate) cation (ABTS+) radical scavenging activities of compounds 4a1, 4e1, 4e2, 4f 1, 4f2, 4g1, 4g2, 4h1, 4h2, 4k1, 4k2, 4n1 and 4n 2, superoxide anion radical scavenging activities of 4b1, 4e1, 4f2, 4j1, 4k1, 4k2, 4m1, 4m2, and 4n2, and hydroxyl radical scavenging activity of almost all the compounds except 4f1, 4f 2, 4j2, 4l1 and 4l2 were better than that of the commercial antioxidant butylated hydroxytoluene (BHT).

A series of novel binuclear Pd(II) complexes of the type [(PPh 3)2ClPd(L)PdCl] [where L = dianionic bridged ligands derived from 2-oxo-1,2-dihydroquinoline-3-carbaldehyde or its derivatives with o-aminophenol/o-aminothiophenol] have been reported. The new complexes have been characterized by elemental analysis, FT-IR, UV-Vis and NMR (1H and 31P) spectroscopic techniques. The coordination mode of the ligands and the geometry of the complexes were confirmed by single crystal X-ray crystallography of one of the complexes. The catalytic efficiency of one of the binuclear Pd(II) complexes was tested for N-arylation of imidazole.
