Project TitleBranched Arginine Based Poly(Ester Urea Urethane) Nanoparticles as Drug Delivery (Chemotherapeutic) Vehicles
Track Code7531
Short Description

Self-assembled nanoparticles (NPs) composed of linear and branched Arginine-based poly-ester urea urethanes (Arg-PEUUs) as carriers for cancer treatments.


These self-assembled nanoparticles are easily prepared by a facile dialysis method. Their assembly is directed by a combination of hydrophobic/hydrophilic interactions. By varying the ratio of polymer as well as varying functional groups, the size of the nanoparticles (100-300 nm) as well as their mechanical and hydrophobic properties can be finely tuned. Likewise, photoactive groups suitable for crosslinking can be included to further enhance nanoparticle stability. Even prior to drug loading these nanoparticles enhance macrophage production of TNF-α and nitric oxide.


These nanoparticles can be loaded with a variety of chemotherapeutic agents including doxorubicin (DOX) and gambogic acid (GA). In vitro studies performed with GA-loaded nanoparticles, a low solubility chemotherapeautic, showed 80-90% release within 60h. Additional studies show that external folate functionalization can be added to the nanoparticle to enhance cell attachment and facilitate internalization thereby improving the anti-cancer drug potency. Further in vivo studies on MCF-7 (invasive breast ductal carcinoma) xenograft mice show promising results.
