Abstract

Two new Ru(II) polypyridyl complexes [Ru(phen)₂(adppz)](ClO₄)₂ (1) and [Ru(dip)₂(adppz)](ClO₄)₂ (2) have been synthesized and characterized. The DNA-binding constants were determined to be 6.54 ± 0.42 × 10(5) and 7.65 ± 0.20 × 10(5)M(-1) for complexes 1 and 2. DNA binding experiments indicated that complexes 1 and 2 interact with DNA through intercalative mode. Antioxidant activity shows that the complexes have significant hydroxyl radical scavenging activity. Cytotoxic activities suggest that the complex 2 exhibits higher cytotoxic activity against BEL-7402, MG-63 and SKBR-3 cells than complex 1 under identical conditions. Complexes 1 and 2 can induce apoptosis of BEl-7402 cells. We have identified several cellular mechanisms induced by 1 and 2 in BEL-7402 cells, including the level detection of ROS, activation of procaspase 3, caspase 7, the expression of antiapoptotic proteins Bcl-x, Bcl-2, proapoptotic proteins Bad, Bax, Bid and cell cycle arrest. Thus, complexes 1 and 2 inhibit growth of BEL-7402 cells through induction of apoptotic cell death, enhancement of ROS levels and S-phase and G0/G1 cell cycle arrest. Further investigations have shown that complex 2 induces apoptosis by regulating the expression of Bcl-2 family proteins.
