Abstract

See full text

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.
