Publication number: 20110110886Abstract: 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.Type: ApplicationFiled: June 15, 2009Publication date: May 12, 2011Inventor: Demetrios Braddock

Patent number: 7872152Abstract: 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.

Publication number: 20110009351Abstract: 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.Type: ApplicationFiled: May 9, 2008Publication date: January 13, 2011Inventors: David Y. Thomas, John Hanrahan, Graeme Carlile, Renaud Robert

Patent number: 6939566Abstract: 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.Type: GrantFiled: January 17, 2001Date of Patent: September 6, 2005Inventors: Kareem I.
