  • Patent number: 6147245
    Abstract: A unique method for the synthesis of substantially pure .alpha.-keto bisphosphonate esters and the usage of these esters in reactions with C, N, O, or P nucleophiles for synthesis of .alpha.-functionalized bisphosphonates. The method starts with a reaction mixture formed of an .alpha.-diazo methanediphosphonate ester, including tert-butylchlorite, a polar aprotic organic solvent, and an effective amount of water. After synthesis is complete, a water trapping reagent may be added to remove any excess water. The present invention provides a versatile pathway to new .alpha.-substituted bisphosphonate derivatives and could be readily adapted to combinatorial drug discovery synthetic strategies. The .alpha.-keto bisphosphonate esters can be converted to the corresponding acids by acid hydrolysis or mild silyldealkylation.

  • Patent number: 5955453
    Abstract: Membrane-permeant phosphoinositides, including phosphatidylinositol phosphate esters, are described. A membrane-permeant phosphoinositide includes groups that neutralize the charges of the phosphate moieties of the phosphoinositide. A cell can be treated with the membrane-permeant phosphoinositide, which is then absorbed into the cell. The neutralizing groups can be removed intracellularly to afford the charged phosphoinositide.

  • Patent number: 5756774
    Abstract: Provided herein are novel syntheses of the phosphate-based inositol derivatives 1-O-?(+)-menthoxycarbonyl!-6-O-benzyl-2,3:4,5-di-O-isopropylidene-myo-inos itol (D4P), D-myo-inositol 1,4,5-trisphosphate (D-IP.sub.3), 6-O-benzyl-2,3:4,5-di-O-isopropylidene-myo-inositol H-phosphonate ((-)-3-HP) and L-myo-inositol 1,4,5-trisphosphate (L-IP.sub.3). These syntheses employ fewer column chromatography steps for the isolation of intermediates than do prior art syntheses, and hence, are more convenient, economical and efficient than are the previously known synthetic methods.
