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.

Abstract: A diagnostic agent for infectious diseases which is capable of distinguishing among different kinds of bacterial species and which allows simple and non-invasive measurement and/or imaging in a short period of time is provided; and a screening method for a therapeutic agent for infectious diseases caused by microorganisms are provided. A diagnostic agent for infectious diseases caused by nitroimidazole susceptible microorganisms, containing an imidazole derivative or a fused imidazole derivative having at least one nitro group on an imidazole ring, or a labeled form thereof as an active ingredient is provided.
Abstract: The present invention relates to certain nitroimidazole compounds, which have interesting pharmaceutical properties. In particular, the compounds are useful in the treatment and/or prevention of infections such as those caused by Mycobacterium tuberculosis, Trypanosoma cruzi or Leishmania donovani. The invention also relates to pharmaceutical compositions containing the compounds, as well as processes for their preparation.

Abstract: The use of levo-ornidazole in the preparation of anti-parasitic infection drug is provided. It is demonstrated that levo-ornidazole is superior to dextro-ornidazole and racemic ornidazole in the therapeutic action against parasitization (especially trichomonas vaginalis infection and cecal amoeba infection), and thus it is more practicable to formulate L-ornidazole as anti-parasitic infection drugs, and particularly as drug preparations which are suitable for clinical uses, including oral preparation, intravenous preparation and vaginal preparation.
Abstract: Novel chiral derivitaves of non-nucleoside inhibitors (NNI), particularly R-isomers of halopyridyl and thiazoyl thiourea compounds are provided as potent inhibitors of reverse transcriptase (RT), and particularly of retroviral RT, most particularly HIV RT. The stereospecific compounds and compositions of the invention inhibit replication of retrovirus, particularly human immunodeficiency virus-1 (HIV-1) and drug resistant strains.
