Preparation and tumor-targeting evaluation of BS-CyP albumin nanoparticles modified with hyaluronic acid based on boron neutron capture therapy
Radiation therapy has been widely used in the clinical treatment of tumors. Due to the low radiation absorption of tumors, a high dose of ionizing radiation is often required during radiotherapy, which causes serious damage to normal tissues near tumors. Boron neutron capture therapy (BNCT) is more targeted than conventional radiotherapy. To improve the therapeutic effect of cancer, albumin was selected as the drug carrier to wrap the fluorescent tracer boron drug BS-CyP and prepare the nanoparticles. Then, we developed a novel tumor-targeting nano-boron drug by using hyaluronic acid to modify the nanoparticles. We found that BS-CyP albumin nanoparticles modified with hyaluronic acid effectively delayed drug release and enhanced the aggregation, in tumors, showing good safety with no obvious toxicity to cells and mice. This study confirmed the advantages of boron drugs modified with hyaluronic acid targeting tumors and may provide a reference for BNCT.
