The clinical treatment of gastric cancer is hampered by the development of anticancer drug resistance as well as the unfavorable pharmacokinetics, nontarget toxicity, and inadequate intratumoral accumulation of current chemotherapies. The polyphenol epigallocatechin gallate in combination with doxorubicin exhibits synergistic inhibition P-glycoprotein efflux pump activity and cancer cell growth. This study evaluated a potential activated nanoparticle delivery system comprising a hyaluronic acid complex with polyethylene glycol-conjugated gelatin containing encapsulated epigallocatechin gallate and low-dose doxorubicin, which may facilitate targeted drug administration to gastric cancer cells. We confirmed successful delivery of bioactive combination drugs and internalization into gastric cancer cells through CD44 ligand recognition and ensuing inhibition of cell proliferation via caspase-induced apoptosis and G2/M phase cell cycle arrest. Furthermore, the targeted nanoparticles significantly suppressed gastric tumor activity and reduced both tumor and heart tissue inflammatory reaction in vivo compared to systemic combination treatment.
