Publication number: 20110165264Abstract: Use of cilastatin to reduce the nephrotoxicity of different compounds. The invention refers to use of cilastatin to prepare a medicinal product to reduce the nephrotoxicity of a nephrotoxic compound that enters the cells of the proximal tubule through cholesterol rafts. The invention is based on the discovery that a great number of nephrotoxic compounds, including drugs, enter the cells of the proximal tubule through the cholesterol rafts, and that cilastatin is able to interfere with this transport mechanism, decreasing the nephrotoxicity of such compounds to a variable extent. The nephroprotective effect is common to compounds of different chemical nature and solubility and is specific for the kidney, causing no interference with the effects of nephrotoxic drugs having their targets in other organs. Therefore, administration of cilastatin allows for decreasing the nephrotoxic effects of different drugs without reducing their therapeutic effects.Type: ApplicationFiled: July 11, 2008Publication date: July 7, 2011Inventors: Alberto Tejedor Jorge, Alberto Lazaro Fernandez, Sonia Camaño Paez, Ana Maria Torres Redondo, José Antonio Lazaro Manero, Manuela Castilla Barba, Maria del Carmen De Lucas Collantes

Publication number: 20110082099Abstract: The present invention relates to methods and compositions to treat subjects having cystic fibrosis. These compositions comprise the class of isothiocyanates. Isothiocyanates, absorbed by a cell are conjugated with glutathione GSH by glutathione-s-tranferase (GST). The conjugates are substrates of the multi-drug resistance associated (MRP)/multi-drug resistance (MDR) proteins. These proteins are functionally redundant to the cystic fibrosis transmembrane conductance regulator (CFTR), allowing for the substrate conjugates to be exported from the cell. The export of GSH conjugates restores intracellular and extracellular levels of GSH to normal levels. Normalizing both extracellular and intracellular GSH via the increased conjugation of isothiocyanates with GSH, and subsequent export, can significantly rectify numerous enzymatic processes and correct the pathologies that are typical of patients suffering from cystic fibrosis.Type: ApplicationFiled: June 14, 2010Publication date: April 7, 2011Inventor: Melanie Childers

Publication number: 20100233225Abstract: A first embodiment is a coating for a surface comprising an electrostatic self-assembly creating one or more coating layer(s); (i) wherein one or more high molecular weight bioactive molecule(s) is bound to a protein carrier wherein said protein carrier or said bound bioactive molecule is further bound to one or more of said coating layer(s) and/or (ii) wherein one or more low molecular weight bioactive molecule(s) is/are incorporated within one or more of said layers or later introduced to said layer or layers by post-treatment. A second embodiment is a method of coating a surface comprising introducing said surface into a solution of one or more positively charged water-soluble polyelectrolytes at a pH ranging from about 2 to about 12 and at a temperature ranging from about 4° C. to about 80° C. and incubating said surface for about 0.Type: ApplicationFiled: February 11, 2008Publication date: September 16, 2010Inventor: Bingyun Li

Patent number: 7795316Abstract: Ophthalmic pharmaceutical compositions containing tobramycin, dexamethasone and deacetylated xanthan gum are described. The compositions provide longer ocular retention for enhanced ocular bioavailability of tobramycin and dexamethasone. In a preferred embodiment, the compositions also provide for improved suspension of dexamethasone. The concentration of ionizable species in the compositions is controlled so as to prevent precipitation of the xanthan gum as a result of ionic interactions between tobramycin and xanthan gum, while allowing for a restoration of viscosity upon topical application of the compositions to the eye. The use of deacetylated xanthan gum is disclosed, so as to avoid formulation instability caused by pH drift during storage.Type: GrantFiled: December 19, 2007Date of Patent: September 14, 2010Assignee: Alcon Research, Ltd.Inventor: Bhagwati P. Kabra

Publication number: 20100204171Abstract: Various aspects related to the preparation of congeners of the aminoglycosides gentamicin such as the congener C2 and using this compound or derivatives thereof and pharmaceutically active salts to treat diseases that involve genetic mutations which introduce a missense or premature stop codon into a gene. Still other aspects include treating human or animal patients with the gentamicin congener C2 and derivatives and pharmaceutical salt thereof to overcome, or to at least mitigate, the symptoms of disease and disorders such as some forms of Becker's or Duchenne muscular dystrophy, Hurler's Syndrome and Cystic Fibrosis that have as their etiology the presence of a premature stop codon in a gene whose proper expression is necessary for good health.Type: ApplicationFiled: May 28, 2009Publication date: August 12, 2010Inventors: Bruce A. Molitoris, David M. Bedwell, Ruben M. Sandoval
