Reaction of compounds 3 (A) and 4 (B) with the target peptide QLMPFGCL based on product analysis by LC–MS. T2’ and T2 stand for the amidine-linked and amine-linked quinazoline ligand (X=O), respectively. (C) Characterization of adduct A4 by MS/MS, confirming the structure and the sequence specificity of a [Pt(pn)]2+ chelate (inset). Selected fragment ions are labeled; see the ESI† for a complete list of b and y ions.
