  • Patent number: 11400079
    Abstract: Bromine induced lactamization of vinyl acetohydroxamates facilitated syntheses of monocyclic ?-lactams suitable for incorporation of a thiomethyl and extended functionality at the C(4) position. Elaboration of the resulting substituted N-hydroxy-2-azetidinones allowed incorporation of functionalized ?-amino substituents appropriate for enhancement of antibiotic activity. Evaluation of antibacterial activity against a panel of Gram-positive and Gram-negative bacteria revealed structure-activity-relationships (SAR) and identification of potent new monobactam antibiotics. The corresponding bis-catechol conjugate, 42, has excellent activity against Gram-negative bacteria including carbapenemase and carbacephalosporinase producing strains of Acinetobacter baumannii which have been listed by the WHO as being of critical concern worldwide.

  • 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.

  • Publication number: 20110045029
    Abstract: A composition for oral delivery of a poorly absorbed drug is disclosed. The composition includes the drug, an enhancer for increasing absorption of the drug through the intestinal mucosa, a promoter, which further increases the absorption of the drug in the presence of the enhancer, and optionally a protector for protecting the drug from physical or chemical decomposition or inactivation in the gastrointestinal tract. Illustrative enhancers include sucrose fatty acid esters, and illustrative promoters include aminosugars and amino acid derivatives, such as poly(amino acids). Illustrative protectors include methylcellulose, poly(vinyl alcohol), and poly(vinyl pyrrolidone).
