Cisplatin (cis-diamminedichloroplatinum(II)) and its analogs are known to form 1,2-intrastrand cross-links with guanine bases that lead to DNA distortion and are responsible for cytotoxicity. Reaction with proteins, especially at methionine residues, could also be responsible for cytotoxicity (Sandlin, R. D. et al. 2010). A new tridentate platinum(II) complex with a piperazine ring was successfully designed and synthesized. In this complex, the platinum is coordinating to all three nitrogens of (1,2- dimethylaminoethylpiperazine), which makes it a Platinum triamine compound. A series of chemical reactions of this compound with guanosine 5’-monophosphate (5’-GMP) and N-acetylmethionine (N-AcMet) were conducted under different conditions. Reactions with 5’-GMP show spectra suggesting that the triamine ligand is partially displaced as a second 5’-GMP residue coordinates. We are hoping that this newly synthesized compound may have anticancer properties, due the bulky structure of its nitrogen ligand.
