摘要

Aim: Nano-diamino-tetrac (NDAT) targets a receptor on integrin αvβ3; αvβ3 is generously expressed by cancer cells and dividing endothelial cells and to a small extent by nonmalignant cells. The tetrac (tetraiodothyroacetic acid) of NDAT is covalently bound to a poly(lactic-co-glycolic acid) nanoparticle that encapsulates anticancer drugs. We report NDAT delivery efficiency of cisplatin to agent-susceptible urinary bladder cancer xenografts. Materials & methods: Cisplatin-loaded NDAT (NDAT-cisplatin) was administered to xenograft-bearing nude mice. Tumor size response and drug content were measured. Results: Intratumoral drug concentration was up to fivefold higher (p < 0.001) in NDAT-cisplatin-exposed lesions than with conventional systemic administration. Tumor volume reduction achieved was NDAT-cisplatin > NDAT without cisplatin > cisplatin alone. Conclusion: NDAT markedly enhances cisplatin delivery to urinary bladder cancer xenografts and increases drug efficacy.
