title: Anionic phthalocyanines targeting G-quadruplexes and inhibiting telomerase activity in the presence of excessive DNA duplexes.
abstract: Anionic phthalocyanines inhibited efficiently telomerase activity even in the presence of excess double-stranded DNA (dsDNA) because of their selective binding to telomere G-quadruplex, although low selectivity of a typical cationic ligand, TMPyP4, to the G-quadruplex allowed telomerase reaction under conditions with dsDNA.
