  • Lipophilic salts of S-adenosyl-L-methionine (SAM) with acylated taurine derivatives
    Patent number: 5073546
    Abstract: Liposoluble salts of S-adenosyl-L-methionine (SAM) with acyl derivatives of taurine having the formula:SAM.sup.n [R--CO--NH--(CH.sub.2).sub.2 --SO.sup.-.sub.3 ].sub.nin which R--CO is a member selected from C.sub.12 -C.sub.26 saturated and unsaturated, linear and branched acyl, and C.sub.2 -C.sub.26 cycloalkyl-substituted acyl, and n is from 3 to 6 according to the SAM charge, and pharmaceutical compositions containing the salts.
    Type: Grant
    Filed: May 29, 1990
    Date of Patent: December 17, 1991
    Inventors: Vincenzo Zappia, Mario DeRosa
  • Cosmetic preparations containing ubidecarenones
    Patent number: 4883670
    Abstract: Ubidecarenones are effectively dissolved in an aqueous medium using N-acyl-2 amino-ethanesulphonates in which the acyl residue has more than 5 carbon atoms. Cosmetic compositions containing ubidecarenones so solubilized are effective in anti-aging and hydrating treatment.
    Type: Grant
    Filed: June 20, 1988
    Date of Patent: November 28, 1989
    Assignee: Arval S.p.A.
    Inventors: Vincenzo Zappia, Mario De Rosa
  • Macromolecular CDP-choline derivatives, process for their preparation and pharmaceutical compositions containing them
    Patent number: 4772463
    Abstract: CDP-choline derivatives with macromolecules containing carboxy groups, such as polyacrylates, polymethacrylates, polyglutamates, polyaspartates and polymaleates, or copolymers of acrylic acid and methacrylic acid with methyl acrylate, methyl methacrylate or acrylamide.The polymeric derivatives of the invention gradually release CDP-choline, due to the action of enzymes present in the organism, thus exerting also a protective effect on the CDP-choline molecule.
    Type: Grant
    Filed: September 30, 1986
    Date of Patent: September 20, 1988
    Inventors: Vincenzo Zappia, Mario De Rosa
  • Stable salts of S-adenosyl-L-methionine with polyanions
    Patent number: 4764603
    Abstract: Stable salts of S-adenosyl-L-methionine with water-soluble polyanions, such as polyphosphates, polyvinylsulfonates -sulfates or -phosphates, polyacrylates, polystyrene sulfonates, are described.The salts according to the invention, prepared by precipitation from aqueous solutions of pH not exceeding 3.5, possess peculiar stability, solubility, nonhygroscopicity and are valuable for use as active constituents in pharmaceutical compositions.
