Fluorescent Deferoxamine Complexes of Cu(II) and Zr(IV): Insights in the Development of Dual Imaging Probes

open access: yesChemistry – A European Journal, Accepted Article.
Deferoxamine (DFO) is widely regarded as benchmark chelator for 89Zr(IV), a commonly used PET (Positron Emission Tomography) tracer. We have introduced a novel fluorescent coumarin derivative of DFO (DFOKC), characterized by chelating unit and fluorophore covalently linked via a lysine molecule. This design introduces a free primary amine group, which,

An Efficient Solid‐Phase Synthetic Approach to Prepare TACN‐Functionalized Peptides

open access: yesChemistry–Methods, EarlyView.
By recruiting fluorescent dye NBD as a protecting group, Bis‐NBD‐NO1A is developed as a universal building block to functionalize peptides with TACN derivatives via SPPS. The protection of TACN with NBD becomes the first example to functionalize TACN in a controllable manner. The colour‐guided deprotection of NBD enables further elaborations of TACN as
