Patent number: 7247746Abstract: New crystal forms of N-(trans-4-isopropylcyclohexylcarbonyl)-D-phenylalanine, also known asnateglinide, may be produced by dissolving nateglinide in any of its forms, including solvates, in an organic solvent to form a solution followed by precipitation of nateglinide from the solution, and isolating and drying the precipitated crystal form of nateglinide. The precipitation of nateglinide may be induced either by cooling the solution, or by addition of another solvent which is miscible with the first solvent but in which nateglinide is only poorly soluble, or by combination of the two. Depending on the solvent a specific crystal form of nateglinide may be obtained, e.g., the R?-type crystal form of nateglinide produced by the described method has a different melting point, infra red spectra and X-ray diffraction patterns from the previously known crystal forms of nateglinide.Type: GrantFiled: April 14, 2003Date of Patent: July 24, 2007Assignee: Novartis, AGInventor: Paul Allen Sutton

Patent number: 6306576Abstract: Screening methods for asthma and analogous diseases in which activated eosinophils are found at the disease site are provided. The methods involve assaying for the presence of brominated tyrosine species in a bodily sample which has been obtained from a test subject. The brominated tyrosine species are either free in the sample or protein bound. In one embodiment, the assay involved measuring the amount of a brominated tyrosine species, particularly 3-bromotyrosine, 3,5-dibromotyrosine, or combinations thereof (referred to hereinafter collectively as the “diagnostic marker”) in a bodily sample from the test subject. In another embodiment for determining the prognosis of asthma in a test subject, the concentration or content of the diagnostic marker is determined in bodily samples taken from the test subject over successive time intervals. The concentrations are compared to determine the prognosis of the asthma.Type: GrantFiled: February 19, 1999Date of Patent: October 23, 2001Assignee: Cleveland Clinic FoundationInventors: Stan Hazen, Weijia Wu, David Schmitt
