Design, combinatorial synthesis and biological evaluations of novel 3-amino-1′-((1-aryl-1 H -1,2,3-triazol-5-yl)methyl)-2′-oxospiro[benzo[ a ] pyrano[2,3- c ]phenazine-1,3′-indoline]-2-carbonitrile antitumor hybrid molecules
activity against the A549 cancer cell line with IC50 value of 5.4 μM. All compounds had low or no effect against L02 and HUVEC non-cancer cell lines. Compound 36 was further confirmed to mainly locate mitochondria in A549 cancer cells via laser-scanning confocal microscopy. Moreover, compound 36 was proved to increase ROS production and induce cellcyclearrest in Sphase. Western blot analysis illustrated

Metal complexes of a hexameric network tetrapyrazineporpyrazine were synthesized by template polycyclotetramerization of pyrazine-2,3,5,6-tetracarboxamide in an urea melt in the presence of a corresponding metal acetate; irrespective of the metal, the polymerization degree of the polymeric ligand does not exceed six. A method for structural assessment of such compounds was proposed.
A series of novel pyrano[3,2-a]phenazine derivatives (1a-1r and 2a-2q), designed as hybrid molecules of phenazine and pyran pharmocophores, were facilely synthesized in two steps with 77-93% overall yields in this study. Cytotoxic evaluation indicates that many compounds exhibited cytotoxicity against HCT116, MCF7, HepG2 and A549 cancer cell lines in vitro, in which compounds 1c, 1i, 2e, and 2l were

Herein, a mercury(II) ionfluorescentsensor (Z-3) with high sensitivity and immediate response is designed and synthesized. The sensor uses the phenazine group as a luminophore and sulfhydryl as a recognition moiety. The sensor is easily synthesized and it exhibits a remarkable blue shift with Hg2+. Correspondingly, its fluorescence color changes from yellow to blue. In addition, the low naked eye

Detection and removal of heavymetalions in a variety of complex water systems using dyes remains a challenge. Here we have developed a rapid, low-cost, on-site water-soluble dye for the colorimetric/fluorogenic detection and removal of copper ions in natural water and plant samples. By comparing with dye molecule AHP, this water-soluble phenazine dye (AHPN) has a high fluorescence quantum yield and
