Abstract:
Copper (Cu) compounds are a promising candidate for next generation metal anticancer drugs. Therefore, we regulated anions to synthesize four mononuclear and binuclear Cu(II) compounds derived from thiosemicarbazone Schiff base ligands and characterized them. Four of these compounds showed very high cytotoxicity to cancer cell lines in vitro. These Cu(II) compounds strongly promoted the apoptosis of BEL-7404 cells and had a capacity to arrest the cell cycle at S phase of those cells. Furthermore, reactive oxygen species (ROS), mitochondrial membrane potential and Western blot analyses revealed that these Cu(II) compounds exert their cytotoxicity through an ROS-mediated intrinsic mitochondrial pathway accompanied by the regulation of Bcl-2 family proteins.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
