Abstract:A platinum (II) complex has been synthesized and characterized. The complex binding properties with G-quadruplex DNA and ds26 were examined by FID and CD spectroscopic methods. The results revealed that the platinum (II) complex can induce the antiparallel G-quadruplex structure of HTG21 conformation in the absence of added K+ with selectivity over other G-quadruplex DNA and duplex DNA. The cytotoxicity of the platinum (II) was screened against four cancer cell lines and normal cells of HL-7702 in comparison t… Show more
