Pt-based Coordination Complexes
Partner site with the DeRose lab
This collaboration successfully combines the synthetic expertise of the Haley lab with the demonstrated Pt-RNA biochemistry knowledge of UO colleague
Victoria DeRose's lab. The goal of this research is to use chemical biology approaches to identify interactions between platinum-based reagents and
cellular constituents. We are developing Pt(II) analogues that are synthetically modified for post-treatment "click"-chemistry, and use these compounds for identifying binding partners and cellular localization. Haley serves as the synthetic advisor/expert for the preparation of the organic ligands and of the complex fluorophores that are subsequently bound/"clicked" to Pt.
