Convenient detection of metal-DNA, metal-RNA, and metal-protein adducts with a click-modified Pt(II) complex.

ABSTRACT

cis-[Pt(2-azido-1,3-propanediamine)Cl2] is a reagent for high-yield post-treatment fluorescent labelling of Pt(II) biomolecular targets using click chemistry and exhibits a bias in conformational isomers in the context of duplex DNA. Pt-protein adducts are detected using BSA as a model. Following in vivo treatment, long-lived Pt-RNA adducts are detected on ribosomal RNA.
