The invention provides CaO2 nanoparticles having a pH-responsive coating for use in a method of adjuvant therapy of hypoxic tumour cells or tissues. The nanoparticles find particular use in enhancing cancer therapies that depend on oxygen to exert their effect, such as photodynamic therapy (PDT), sonodynamic therapy (SDT), and radiotherapy. The invention also provides pharmaceutical compositions containing the coated CaO2 nanoparticles, together with at least one photosensitiser, sonosensitiser, or radiosensitiser and, optionally, at least one pharmaceutical carrier or excipient.
本发明提供了具有 pH 响应涂层的
CaO2 纳米粒子,可用于缺氧肿瘤细胞或组织的辅助治疗方法。这种纳米粒子特别适用于增强依赖
氧气发挥疗效的癌症疗法,如光动力疗法(PDT)、声动力疗法(
SDT)和放射疗法。本发明还提供了含有涂层 纳米粒子的药物组合物,以及至少一种光敏剂、声敏剂或放射敏剂和可选的至少一种药物载体或赋形剂。
