A long-lived peptide-conjugated iridium( iii ) complex as a luminescent probe and inhibitor of the cell migration mediator, formyl peptide receptor 2

reduced epithelial cell migration capacity and inhibited lipoxin A4 (LXA4)-triggered cell migration in HUVEC cells, demonstrating the ability of this complex to inhibit FPR2 in living cells. To our knowledge, this is the first long-lived probe for imaging FPR2 in living cells.
