Amine chelates capable of antioxidant capacity and amyloid disaggregation are shown which may be useful in targeting metal-based oxidative stress in neurodegenerative disorders. Pyclen, a backbone commonly investigated for contrast agent imaging, may be repurposed as an anti-oxidant chelator for disaggregating amyloid. The antioxidant capacity of pyclen is enhanced dramatically via conversion of the pyridine backbone to a pyridol with cellular studies showing superior antioxidant capacity while retaining chelation ability to protect amyloid from metal ions aggregation and also disaggregate amyloid aggregates. Another family of molecules based upon hybrid heterocyclic amine ligands is also presented.
