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.

Abstract: Tumor resection is commonly practiced to prevent the progression of cancer. However, there are post-surgery concerns including the formation of a void that can allow cancer cells to escape at the surgery site, which increases the risk of metastasis. To counter this challenge, an embodiment includes a polyurethane-based shape memory foam as a tissue void-filling device that can also release anti-cancer drugs. Such foams may activate at body temperature and become malleable. Such properties may enable the foam to be shaped to precisely seal the tissue void and then serve as a drug-eluting device. Based on the drug composition with poly vinyl alcohol (PVA), the drug release profile from the foam may be altered depending on the application.
