  • Patent number: 9480675
    Abstract: Systems and methods are described providing therapeutic preparations of sirtuin inhibitors, such as SIRT1 inhibitors, for stimulating load-induced skeletal muscle growth in the body of a patient. The natural stimulation of SIRT1 activity can be suppressed through increased caloric intake and loading in conjunction with the inhibition of sirtuin activity to improve the inhibitory effect. In addition, known muscle growth promoting agents such as amino acids and hormones can be administered at the same time as the sirtuin inhibitor. The size of the tissue structure to be treated or the body size may be used to determine the therapeutic dose of sirtuin inhibitor. The sirtuin inhibitor and muscle stimulating agents are either locally or systemically delivered at therapeutic doses for the desired effect. The SIRT1 inhibitor Splitomycin is particularly effective.

  • Patent number: 9469626
    Abstract: The invention provides new methods for the direct umpolung self-condensation of 5-hydroxymethylfurfural (HMF) by organocatalysis, thereby upgrading the readily available substrate into 5,5?-di(hydroxymethyl)furoin (DHMF). While many efficient catalyst systems have been developed for conversion of plant biomass resources into HMF, the invention now provides methods to convert such nonfood biomass directly into DHMF by a simple process as described herein. The invention also provides highly effective new methods for upgrading other biomass furaldehydes and related compound to liquid fuels. The methods include the organocatalytic self-condensation (umpolung) of biomass furaldehydes into (C8-C12)furoin intermediates, followed by hydrogenation, etherification or esterification into oxygenated biodiesel, or hydrodeoxygenation by metal-acid tandem catalysis into premium hydrocarbon fuels.

  • Patent number: 9463450
    Abstract: A highly fluorinated polymer is very useful as an acid catalyst. The highly fluorinated polymer has at least two repeating unit types that are the polymerized derivatives of a perfluorinated cyclic or cyclizable compound and a highly fluorinated vinyl ether compound having a sulfur containing functional group. The polymer can be formed by radical copolymerization of the fluorinated monomers with the sulfur-containing functional group in sulfonyl fluoride form (—SO2F) that is subsequently converted to sulfonic acid form (—SO3H). The highly fluorinated polymer can be used to advantage in a solution comprising an aprotic, polar organic solvent that has a dielectric constant of at least 15 and preferably is free of hydroxyl functional groups. Suitable solvents are those in which the polymer is soluble to at least 1 wt %. Hydroxyl group-containing protic, polar organic solvents are less preferred.
