Synthesis and crystal structure of two new dinuclear cobalt(II) complexes interaction with HeLa cells

►We synthesis two novel dinuclear Co(II) complexes, and extracted HC-DNA (HeLa cells DNA). ►The binding behaviors of the complexes with extracted HC-DNA were investigated by fluorescence spectroscopy. ►Their cleavage behavior toward extracted HC-DNA, cytotoxicity in vitro and apoptosis were also investigated.
