In this study, two series of 3-oxo-3H-benzo[f]chromene-2-carboxylic acid derivatives (compounds 5a-i and 6a-g) were synthesized. Their in vitro proliferation inhibitory activities against the A549 and NCI-H460 human non-small cell lung cancer (NSCLC) cell lines were evaluated. Their photophysical properties were measured. Among these target compounds, 5e(More)
Through a structure-based molecular hybridization approach, a series of novel quinazolinyl-diaryl urea derivatives were designed, synthesized, and screened for their in vitro antiproliferative activities against three cancer cell lines (HepG2, MGC-803, and A549). Six compounds (7 g, 7 m, 7 o, 8 e, 8 g, and 8 m) showed stronger activity against a certain(More)
Two G-quadruplex ligands: [Co(H-La)2Cl2] (Co1) and [Co(Lb)2][CoCl4]⋅2H2O (Co2) have been synthesized and characterized. Two cobalt oxoisoaporphine complexes exhibited selective cytotoxicity to SK-OV-3/DDP cells than for HL-7702 cells. Cytotoxic mechanism studies indicated that both Co1 and Co2 were telomerase inhibitor targeting c-myc, telomere, and bcl-2(More)
Two compounds previously isolated from traditional Chinese medicine, Menispermum dauricum (DC), 6-hydroxyl-oxoisoaporphine (H-La), and 4,6-di(2-pyridinyl)benzo[h]isoindolo[4,5,6-de]quinolin-8(5H)-one (H-Lb), were known to have in vitro antitumor activity and to selectively bind human telomeric, c-myc, and bcl-2 G-quadruplexes (G4s). In this study, the(More)
