  • Publication number: 20120009193
    Abstract: The present invention relates generally to the modulation of hyaluronan (HA) synthesis and degradation. More particularly, the present invention provides compositions and methods for modulating the expression of genetic material encoding HA synthase (HAS) and other enzymes or receptors primarily involved in hyaluronan metabolism; or modulating the proteins that synthesise or degrade hyaluronan including HAS function or activity. The compositions include or comprise nucleic acid molecules and interactive molecules such as antibodies and small molecule inhibitors and HAS substrate analogs. The present invention further contemplates modulation of cellular proliferation, useful in the prophylaxis and/or treatment of inflammatory disorders including hyperproliferative conditions, such as but not limited to, cancer and psoriasis.

  • Publication number: 20110201794
    Abstract: Methods are described for the preparation of combinatorial libraries of potentially biologically active disaccharide compounds. These compounds are variously functionalized, with a view to varying lipid solubility size, function an other properties, with the particular aim of discovering novel drug or drug-like compounds, or compounds with useful properties. The invention provides intermediates, processes and synthetic strategies for the solution or solid phase synthesis of disaccharides, variously functionalized about the sugar ring, including the addition of aromaticity and charge, and the placement of pharmaceutically useful groups and isosteres.

  • Publication number: 20090306012
    Abstract: The present invention relates to the field of chemotherapy of diseases such as cell proliferation disorders including cancer. In particular, the present invention relates to the use of hyaluronan (HA) as a protective agent in the treatment of subjects. HA is administered in conjunction with a chemotherapeutic agent to facilitate the prolonged administration of a dose of the chemotherapeutic agent to be administered to a subject. Owing to the protective effects of the HA, the dose of chemotherapeutic agent may be substantially higher than a generally accepted effective dose, which would otherwise be expected to cause unacceptable side effects in the subject.

  • Publication number: 20090068183
    Abstract: The present invention is directed to compounds, agents, pharmaceutically active agents, medicaments, therapeutics, actives, drugs and the like which specifically target a portion of the HAS molecule which is accessible to the extracellular environment in a first form of a cell but which is not accessible to the extracellular environment in another form of or in a transformed cell form the same or related cell. In particular, the present invention provides compounds which target a portion of HAS which is accessible to the extracellular environment in malignant or inflammatory or proliferative cells but which portion is not accessible to the external environment in “normal” cells. A “normal” cell in this instance is a non-malignant, inflammatory or proliferative cell.
