  • Patent number: 9084779
    Abstract: Novel compounds which are derivatives of tetra-O-methyl nordihydroguaiaretic acid (NDGA), as well as pharmaceutically acceptable salts, solvates, and stereoisomers thereof are provided. These NDGA derivatives have a nitroimidazole moiety and these derivatives show preferential toxicity to hypoxic cells as hypoxic cytotoxins. Their cytotoxicity toward hypoxic cells is a result of abstraction of hydrogen from target molecules by free radicals formed in the reduction of the nitro group. This makes the disclosed compounds an effective anti cancer drug because hypoxic cells are generally considered to be more resistant to anti cancer drugs than normal cells. Pharmaceutical compositions comprising such compounds, as well as methods of use, and treatment for cancers, including hepatocellular carcinoma, breast cancer and prostate cancer, are also provided.
    Type: Grant
