The invention features a class of 2-nitroimidazole compounds with a secondary basic nitrogen atom and a linker bearing one or more therapeutic agents, cytotoxic agents, detectable labels, or chelating groups. In particular, the invention provides 2-nitroimidazole compounds containing a cluster of boron atoms for use in boron neutron capture therapy (BNCT). The 2-nitroimidazole compounds can be used to treat hypoxic conditions, including, e.g., cancer, inflammation, and ischemia. The weakly basic 2-nitroimidazole compounds target to hypoxic tissue and provide increased tissue concentration overall.
这项发明涉及一类具有次生碱性氮原子和携带一个或多个治疗剂、细胞毒剂、可检测标签或螯合基团的2-硝基咪唑化合物。具体而言,该发明提供了含有硼原子簇的用于硼中子俘获疗法(BNCT)的2-硝基咪唑化合物。这些2-硝基咪唑化合物可用于治疗缺氧情况,包括癌症、炎症和缺血等病症。这些弱碱性的2-硝基咪唑化合物靶向于缺氧组织,并提供整体组织浓度的增加。
