Abstract

This invention concerns the incorporation of curcumin into the backbone of a hydrolytically degradable crosslinked hydrogel that utilizes poly(beta amino ester) (PBAE) chemistry to provide a tunable protective network with the ability to release at a controlled rate. Upon the introduction of these microparticle systems in to a free radical generating environment, the constituent amount of curcumin present in solution was improved in comparison to a free curcumin state. From these results, a kinetic rate model was developed to estimate oxidative consumption parameters of curcumin and curcumin monoacrylate and quantify theoretical levels of free radicals present depending on the rate of release of curcumin provided. Modeled curcumin conjugated PBAE microparticles improve translation and overall success in delivering a therapeutic agent that matches levels of oxidative stress.
