  Three novel series of dihydrotriazine derivatives bearing 1,3-diaryl pyrazole moieties were designed, synthesized and evaluated in terms of their antibacterial and antifungal activities. Most of the synthesized compounds showed potent inhibition of several Gram-positive bacterial strains (including multidrug-resistant clinical isolates) and Gram-negative bacterial strains with minimum inhibitory concentration

  Structure-activity relationship analysis further revealed that the presence of 2,4-dichloro moiety surprisingly influenced the activity of the compounds. Molecular docking studies of the compounds into the crystal structure of topoisomerase II and topoisomerase IV suggest that compounds 3a and 4b preferably interact with the targets through hydrogen bonding.

  Three series of 1,3-diaryl pyrazole derivatives bearing aminoguanidine or furan-2-carbohydrazide moieties have been synthesized, characterized and evaluated for antibacterial and anti-inflammatory activities. Most of the synthesized compounds showed potent inhibition of several Gram-positive bacterial strains (including multidrug-resistant clinical isolates) and Gram-negative bacterial strains with minimum inhibitory concentration values in the range of 1-64 mu g/mL. Compounds 6g, 6l and 7l presented the most potent inhibitory activity against Gram-positive bacteria (e.g. Staphylococcus aureus 4220), Gram-negative bacteria (e.g. Escherichia coli 1924) and the fungus, Candida albicans 7535, with minimum inhibitory concentration values of 1 or 2 mu g/mL. Compared with previous studies, these compounds exhibited a broad spectrum of inhibitory activity. Furthermore, compound 7l showed the greatest anti-inflammatory activity (93.59% inhibition, 30 min after intraperitoneal administration), which was more potent than the reference drugs ibuprofen and indomethacin.

  A novel series of 2-(1H-pyrazol-4-y1)-1H-imidazo[4,5-f][1,101phenanthrolines were designed, synthesized and evaluated for their antitumor activity against lung adenocarcinoma by CCK-8 assay, electrophoretic mobility shift assay (EMSA), UV-melting study, wound healing assay and docking study. These compounds showed good inhibitory activities against lung adenocarcinoma. Especially compound 12c exhibited potential antiproliferative activity against A549 cell line with the half maximal inhibitory concentration (IC50) value of 1.48 mu M, which was a more potent inhibitor than cisplatin (IC50 = 12.08 mu M) and leading compound 2 (IC50 = 1.69 mu M), and the maximum cell inhibitory rate being up to 98.40%. Moreover, further experiments demonstrated that compounds 12a-d can strongly interact with telomeric DNA to stabilize G-quadruplex DNA with increased am values from 12.44 to 20.54 degrees C at a ratio of DNA to compound 1:10. These results implied that growth inhibition of A549 cells mediated by these phenanthroline derivatives is possibly positively correlated to the fact their interaction with telomeric G-quadruplexs.
