Representative Matters

  • U.8. Patent  8,492,139.  Detection system for high sensitivity fluorescent assays. This invention relates to a detection system for measuring a fluorescent signal in a fluorescent assay. The system comprises a probe having a small sensing surface bound with a fluorescent label, and a light source and a detector both mounted at the proximal side of the sensing surface of the substrate. The invention also relates to a method for detecting an analyte in a liquid sample using a probe tip having a small surface area and a high molecular weight polymer having multiple binding molecules and multiple fluorescent labels.
  • U.S. Patent 8,476,316.  3-methanesulfonylpropionitrile for treating inflammation and pain.  This invention is in clinical trial for treating osteoarthritis.   The invention is directed to purified 3-methanesulfonylpropionitrile and a pharmaceutical composition comprising the purified compound. The invention is further directed to a method for treating inflammation, inflammatory-related disorders, or pain. 
  • U.S. Patent 8,299,096.  Method for treating pulmonary diseases using rho kinase inhibitor compounds. This invention is directed to methods of preventing or treating diseases or conditions of the lungs associated with excessive cell proliferation, remodeling, inflammation, vasoconstriction, bronchoconstriction, airway hyperreactivity and edema. The method comprises administering to a subject an effective amount of a rho kinase inhibitor compound to treat the disease.
  • U.S. Patent 8,188,076.  Compositions, synthesis, and methods of utilizing arylpiperazine derivatives.  This invention is in clinical trial for treating schizophrenia.  This invention provides arylpiperazine derivatives having Formula I which can be used for treating schizophrenia and related psychoses such as acute manic, bipolar disorder, autistic disorder and depression.
  • U.S. Patent  8,007,813.  CD95-Fc fusion proteins.  This invention is directed to a fusion protein comprising (i) one first domain comprising a ligand binding domain of the CD95 receptor fused to (ii) a second domain comprising a portion of a constant immunoglobulin domain.
  • U.S. Patent  7,977,307.  Method for reducing pain with ziconotide and morphine.  This invention is directed to a method for reducing pain in a human patient by administering ziconotide and morphine by continuous intrathecal infusion.
