  • Patent number: 6730788
    Abstract: Process for preparing 1,10-phenanthroline ligands represented by the formula which comprises coupling a 1,10-phenanthroline of the formula with a ketone e.g. a dialkyl, cycloalkyl or bicycloalkyl ketone with a metal coupling reagent, preferably a lanthanide II e.g. samarium II, wherein R is hydrogen, alkyl, cycloalkyl, bicycloalkyl or aryl e.g. phenyl. The hydroxy group of the product may be converted to derivatives e.g. esters and ethers to form additional ligands. The hydroxy group of the product also may be converted to a reducible group e.g. the methoxy ether and the ether replaced by hydrogen in the reduction. The reduction product wherein R of the starting material is hydrogen can be coupled with a ketone in the process to provide 2,9-disubstituted 1,10-phenanthroline ligands. The ligands provided are preferably in chiral form and complex with metals, e.g. transition metals, which serve as catalysts in many processes such as addition and substitution reactions.

  • Patent number: 6689887
    Abstract: Certain non-nucleoside compounds that will selectively inhibit telomerase by targeting the nucleic add structures, such as G-quadruplexes, that may be associated with human telomeres or telomerase have been identified. Inhibition of human telomerase by two perylenetetracarboxylic acid diimides and a carbocyanine has been demonstrated. 1H-NMR studies have evidenced the stabilization of a G-quadruplex by the perylenetetracarboxylic acid diimide compounds and provided evidence that these and structurally related compounds inhibit the telomerase enzyme by a mechanism consistent with interaction with G-quadruplex structures.
