Despite developments in novel cancer therapies, Cisplatin is often the initial therapy administered for a variety of tumors. Unfortunately, innate or acquired Cisplatin resistance is a very real problem. Trans platinum complexes have classically been dismissed at ineffective, but modifications to the classical diammine/ dichloro motif have produced some promising trans candidates. In collaboration with Dr. Adoracion Quiroga of the University of Madrid, we are attempting to characterize the mechanism of action of trans– isopropylamine-triphenylphosphine diiodine Pt(II). We have assayed the cytotoxicity, cell cycle and apoptosis of this complex in several human cell lines, some with Cisplatin resistance. Future work includes Pt uptake and interstrand cross-linking.
