Tandem Mass Spectrometric Analysis of Metallocene Adducts with Short Oligonucleotides

open access: yes, 2015
Metallocene dichlorides constitute a remarkable class of antineoplastic agents that are highly effective against several cancer cell lines. They were shown to accumulate in the DNA-rich region, which suggests DNA as the primary target.
