Two highly active anticancer Pt(II) complexes, [Pt(Jat1)Cl]Cl (Pt1) and [Pt(Jat2)Cl]Cl (Pt2), containing jatrorrhizine derivative ligands (Jat1 and Jat2) are described. Cell intake study showed high accumulation in cell nuclear fraction. Pt1 and Pt2 exhibited high selectivity for HeLa cancer cells (IC = 15.01 ± 1.05 nM and 1.00 ± 0.17 nM) comparing with HL-7702 normal cells (IC > 150 μM), by targeting p53 and telomerase. Pt2 containing Jat2 ligand was more potent and showed high selectivity for telomerase. It also caused mitochondria and DNA damage, sub-G1 phase arrest, and a high rate of cell apoptosis at the low dose of 1.00 nM. The HeLa tumor inhibition rate (TIR) of Pt2 was 48.8%, which was even higher than cisplatin (35.2%). In addition, Pt2 displayed green luminescent property and potent telomerase inhibition. Our findings demonstrated the promising development of platinum(II) complexes containing jatrorrhizine derivatives as novel Pt-based anti-cancer agents.
