Reactive Oxygen Species Responsive Naturally Occurring Phenolic-Based Polymeric Prodrug.

Reactive Oxygen Species (ROS) play a vital role in the biological system. Exaggerated, ROS have devastating effects on the human body leading to the pathophysiological condition including the transformation of a normal cell into a cancer phenotype. Nature has blessed us with various biomolecules that we use along with our dietary supplements. Using such therapeutic small molecules covalently incorporated into biodegradable polyoxalate polymer backbone with a responsive group forms an efficient drug delivery vehicle. This chapter "Reactive oxygen species responsive naturally occurring phenolic-based polymeric prodrug" will be focusing on redox-responsive polymers incorporated with naturally occurring phenolics and clinical application.
