Abstract

In this manuscript, we describe the implementation of a combinatorial apporach to synthesize a library of copper complexes, associated with an activity-based screening to discover the first peptidyl di copper complex mimicking CAT redox chemistry. The selected dinuclear complex was studied in detail and characterized for its CAT activity in vitro and in cells. Very interestingly, despite moderate intrinsic catalysis constant, this complex was efficacious in a cellular assay.
