  • Publication number: 20110082099
    Abstract: 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.

    Abstract: A surfactant can be added, safely and effectively, to a drug solution containing any antimicrobial agent, such as an antibiotic like tobramycin, that is suitable for administration to the lungs via inhalation. Thus, when an aerosolized drug solution includes surfactant, Marangoni flows cause the drug particles, once deposited in the lungs, to spread over a wider surface area, thereby ensuring greater antimicrobial efficacy. A solution that contains, for example, an antibiotic and tyloxapol or another surfactant providing a similar surface tension to the composition is optimally delivered by the functional combination of a breath-actuated nebulizer and a high-flow compressor.

  • Patent number: 6159706
    Abstract: The present invention provides a method for targeting toxic antimetabolites to gram negative infections. It provides a means of taking advantage of a key disease resistance mechanism to activate these drugs locally, and to overcome the resistance phenotype of the microbes. The invention further provides a method for selecting for antibiotic sensitivity, since a likely mechanism by which organisms are likely to gain resistance to the prodrugs is via loss of enzyme activity, which will make the bacteria sensitive to antibiotics once again.
