Siderophore-mimicking macrocyclic peptoids were synthesized. Peptoid3with intramolecular hydrogen bonds showed an optimally arranged primary coordination sphere leading to a stable catecholate-iron complex. The tris(catecholato) structure of 3-Fe(iii) was determined with UV-vis, fluorescence, and EPR spectroscopies and DFT calculations. The iron binding affinity was comparable to that of deferoxamine, with enhanced stability upon air exposure.

A practical synthesis of preorganized tripodal enterobactin/corynebactin-type ligands (consisting of aC3-symmetric macrocyclic peptoid core, three catecholamide coordinating units, and C2, C4, and C6spacers) is

New 1,3-dicarbonyl biscatecholamide ligands were synthesized to decorporate uranium for nuclear contamination. The derivatives were characterized via1H NMR spectroscopy,13C NMR spectroscopy, FTIR spectroscopy and mass spectrometry. The complexation abilities of ligands 8a–8d with UO22+, Cu2+and Zn2+were determined through spectrophotometric and potentiometric titrations technology. The antioxidant capacities of the ligands were assessed through DPPH antioxidant assay. Results indicated that ligands 8a–8d are potential decorporating agents for uranyl ion (pUO2up to 22.41) and copper(II) ion (pCu up to 17.71) without depletion of the essential element zinc (pZn lower than 7.48).
