Indolo[3,2-b]quinoline derivatives (1) having various amine moieties were prepared and their antitumor activities against P388 leukemia in mice were evaluated, for the purpose of gaining an insight into the role of the amine moiety in the antitumor activity and searching for an effective amine moiety. Introduction of a methylene group between the phenyl group and amino or methanesulfonamido group resulted

An electrochemical article includes: a substrate; a working electrode disposed on the substrate to contact a composition that includes: a fluid; and an analyte to adsorb to the working electrode and comprising an electroactive moiety, the reference electrode being configured to receive a plurality of electrons from the electroactive moiety, to donate electrons to the electroactive moiety, or a combination thereof; a reference electrode disposed on the substrate to contact the fluid; a counter electrode disposed on the substrate to contact the fluid; a heater disposed on the substrate to heat the analyte adsorbed on the working electrode to a selected temperature; and an electrically insulating layer interposed between the heater and the working electrode, the electrochemical article being microfabricated. A process for process for performing electrochemistry includes: introducing a composition to the electrochemical article; and transferring a plurality of electrons between the working electrode and the electroactive moiety to perform electrochemistry.
Synthesis and Evaluation of Quindoline Derivatives as G-Quadruplex Inducing and Stabilizing Ligands and Potential Inhibitors of Telomerase
potent telomeraseinhibitors. The interaction of the G-quadruplex of human telomere DNA with these newly designed molecules was examined via circular dichroism spectroscopy and electrophoretic mobility shift assay (EMSA). The selectivity between the quindoline derivative (4a) and G-quadruplex or duplex DNA was investigated by competition dialysis. These new compounds as inhibitors of telomerase were
