  • Publication number: 20110110886
    Abstract: Autotaxin (ATX) is a prometastatic enzyme initially isolated from the conditioned media of human melanoma cells that stimulates a myriad of biological activities including angiogenesis and the promotion of cell growth, survival, and differentiation through the production of lysophosphatidic acid (LPA). ATX increases the aggressiveness and invasiveness of transformed cells, and ATX levels directly correlate with tumor stage and grade in several human malignancies. To study the role of ATX in the pathogenesis of malignant melanoma, we developed antibodies and small molecule inhibitors against recombinant human protein. Immunohistochemistry of paraffin embedded human tissue demonstrates that ATX levels are markedly increased in human primary and metastatic melanoma relative to benign nevi. Chemical screens identified several small molecule inhibitors with binding constants ranging from nanomolar to low micromolar.

  • Patent number: 7872152
    Abstract: The present invention is generally drawn to novel isolated therapeutic agents, termed resolving, generated from the interaction between a dietary omega-3 polyunsaturated fatty acid (PUFA) such as eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA), cyclooxygenase-II (COX-2) and an analgesic, such as aspirin (ASA). Surprisingly, careful isolation of compounds generated from the combination of components in an appropriate environment provide di- and tri-hydroxy EPA or DHA compounds having unique structural and physiological properties. The present invention therefore provides for many new useful therapeutic di- or tri-hydroxy derivatives of EPA or DHA (resolvins) that diminish, prevent, or eliminate inflammation or PMN migration, for example. The present invention also provides methods of use, methods of preparation, and packaged pharmaceuticals for use as medicaments for the compounds disclosed throughout the specification.

  • Publication number: 20110009351
    Abstract: The present invention relates to a novel assay or screen for identifying compounds with potential therapeutic value for the treatment of protein trafficking diseases such as Cystic Fibrosis (CF) and nephrogenic diabetes insipidus (NDI). The usual approach involves expressing the mutant form of the gene in cells and assaying function in a multiwell format when cells are exposed to libraries of compounds. Although such functional assays are useful, they do not directly test the ability of a compound to correct defective trafficking of the protein. To address this a novel corrector screening assay for CF has been developed in which the appearance of the mutant protein at the cell surface is measured as the assay output. This assay was used to screen more than 3100 compounds. This novel screening approach to protein trafficking diseases is robust and general, and may enable the selection of molecules that can be translated rapidly to a clinical setting.

  • Patent number: 7619000
    Abstract: Arsenic trioxide, an inorganic compound, is commercially available anti-cancer agent but it carries significant toxicity. Organic arsenicals, on the other hand, are much less toxic, to the extent that the methylation of inorganic arsenic in vivo into organic arsenicals has been considered a detoxification reaction. New organic arsenic derivatives have been synthesized, including S-dimethylarsino-glutathione, S-dimethylarsino-thiosuccinic acid and S-dimethylarsino-thiobenzoic acid, and established its potent in vitro cytotoxic activity against numerous human tumor cell lines, both of solid and hematological origin, as well as against malignant blood cells from patients with leukemia. Results form a basis for the development of S-dimethylarsino-glutathione, S-dimethylarsino-thiosuccinic acid, S-dimethylarsino-thiobenzoic acid, and other organic arsenicals as an anti-cancer therapy, combining high efficacy with very low, if any, toxicity.

  • Patent number: 7323044
    Abstract: The invention provides co-solvents for preparing clear solutions of a biocidal agent known as 10, 10?-oxybisphenoxarsine (OBPA). The clear solutions are stable over a relatively broad range of temperatures and have very low Volatile Organic Carbon (VOC) content. They can be included in master batches for the manufacture of plastic materials, such as flexible PVC. The co-solvents of this invention have very low VOC values, do not have troublesome odors, do not cause significant irritation during the high temperature plastic manufacturing process, and are miscible in a range of useful concentrations with plasticizers presently employed by plastics manufacturers. The use of castor oil and/or modified castor oils such as glyceryl ricinoleate, dehydrated castor oil, and certain alkoxylated castor oils as a co-solvent to increase the dissolvable concentration of OBPA, alone or in solution with a plasticizer, was not known or expected.

  • Patent number: 6939566
    Abstract: Microbicidal formulations are described which are preferably ecologically friendly and non-toxic to mammals, and are highly effective against a broad spectrum of detrimental pathogenic microorganisms. The microbicidal formulation contains complexes having the formula R-M, wherein R is at least one organic chelating moiety and M is at least one metal ion which is microbicidal to at least one microorganism. These complexes can disrupt microorganism activities by penetrating the natural protecting bio-films of such microorganisms through the reaction of the R-group with the organic constituents of these microorganisms while releasing M into their intra-cellular media. Thus, this process exhibits its biocidal activities from the inside-out, contrary to other methods which rely on damaging the protective biofilms.

  • Patent number: 6911471
    Abstract: Arsenic trioxide, an inorganic compound, is commercially available anti-cancer agent but it carries significant toxicity. Organic arsenicals, on the other hand, are much less toxic, to the extent that the methylation of inorganic arsenic in vivo into organic arsenicals has been considered a detoxification reaction. New organic arsenic derivatives have been synthesized, including S-dimethylarsino-glutathione, S-dimethylarsino-thiosuccinic acid and S-dimethylarsino-thiobenzoic acid, and established its potent in vitro cytotoxic activity against numerous human tumor cell lines, both of solid and hematological origin, as well as against malignant blood cells from patients with leukemia. Results form a basis for the development of S-dimethylarsino-glutathione, S-dimethylarsino-thiosuccinic acid, S-dimethylarsino-thiobenzoic acid, and other organic arsenicals as an anti-cancer therapy, combining high efficacy with very low, if any, toxicity.

  • Patent number: 6875451
    Abstract: The invention relates to the use of arsenic compounds to treat a variety of neoplastic diseases. The present invention encompasses the administration to a mammal of arsenic in the form of a salt, complex, organic compound or ionic solution to treat tumors of epithelial tissue, connective tissue, central nervous system, lymphoid tissue, hematopoietic cells and tumors associated with oncogenic viruses. This invention also encompasses the treatment of hematopoietic disorders in mammals by the administration of one or more arsenic compounds to said mammal. Further, the arsenic compounds may be used to treat metastatic neoplastic diseases.

  • Patent number: 6770674
    Abstract: A mollusc repellent, which includes a substantially insoluble metal oxalate and a suitable carrier therefor, which exhibits prolonged efficacy. The mollusc repellent is environmentally friendly, being both non-phytotoxic and harmless to non-target animals, and is therefore suitable for use in sustainable agriculture, where the use of toxic chemicals is unacceptable. The mollusc repellent can be used in the form of a solid or as a coating composition.
