Under different pathological conditions, high levels of reactive oxygen species (ROS) cause substantial damage to multiple organs. To counter these ROS levels in multiple organs, we have engineered highly potent novel terpolymers. We found that combination of FDA-approved polyethylene glycol, fumaric acid moieties and electroactive tetra(aniline) by varying the content of tetra(aniline) results into a novel drug composition with biologically active and tunable intrinsic antioxidant properties. To test the intrinsic antioxidative properties of these novel terpolymers, we used alloxan to induce diabetes in rats where ROS generation is known to be higher. The systemic administration of terpolymers to the diabetic rats showed strong electroactive antioxidant behavior which not only normalized ROS levels, but also improved the levels of enzymatic antioxidants including superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH). As a proof-of-principle, we here show TANI based novel drug composition of terpolymers with tunable intrinsic antioxidant properties in multiple organs.
