  The present disclosure provides a once-daily water-soluble pharmaceutically active formulation for oral administration. In certain embodiments, the composition comprises a water-soluble pharmaceutically active organic compound incorporated into a small particulate, each particulate having a core of the water-soluble pharmaceutically active organic compound or an acceptable salt thereof in reversible association with a pharmaceutically acceptable drug-binding polymer. The core of the composition being surrounded by an insoluble water permeable membrane that is capable of delaying the dissolution of the pharmaceutically active compound therewithin and providing for extended release of the pharmaceutically active compound. In some embodiments, the formulation of the invention are designed to extend release of the pharmaceutically active organic compound for about 3 hours to about 8 hours, thereby enabling preparation of an extended release formulation for any pharmaceutically active compound with a half-life of from about 16 hours to about 21 hours.

• Stereochemical Survey of Digitoxin Monosaccharides

  A stereochemically diverse array of monosaccharide analogues of the trisaccharide-based cardiac glycoside natural product digitoxin has been synthesized using a de novo asymmetric approach. The analogues were tested for cytotoxicity against nonsmall cell human lung cancer cells (NCI-H460). The results were compared with digitoxin and its aglycone digitoxigenin. Three novel digitoxin monosaccharide analogues with beta-D-digitoxose, alpha-L-rhamnose, and alpha-L-amicetose sugar moieties showed excellent selectivity and activity. Further investigation revealed that digitoxin alpha-L-rhamnose and alpha-L-amicetose analogues displayed similar anti-proliferation effects but with at least 5-fold greater potency in apoptosis induction than digitoxin against NCI-H460. This study demonstrates the ability to improve the digitoxin anticancer activity by modification of the stereochemistry and substitution of the carbohydrate moiety of this known cardiac drug.

  A highly regio- and stereoselective asymmetric synthesis of various CS'-alkyl side chains of rhamnosyl- and amicetosyl-digitoxigenin analogues has been established via palladium-catalyzed glycosylation with postglycosylated dihydroxylation or diimide reduction. The C5'-methyl group in both alpha-L-rhamnose and cc-L-amicetose digitoxin analogues displayed a steric directed apoptosis induction and tumor growth inhibition against nonsmall cell human lung cancer cells (NCI-H460). The antitumor activity is significantly reduced when the steric hindrance is increased at the C5'-stereocenter.
