  • S-Adenosyl-L-methionine compositions and production thereof
    Patent number: 4242505
    Abstract: S-adenosyl-L-methionine compositions stabilized against decomposition of S-adenosyl-L-methionine comprising S-adenosyl-L-methionine, a sulfuric acid equivalent and a nucleoside sulfate, which are produced from a solution comprising the three essential components in an aqueous solvent by, for example, adding thereto a water-miscible organic solvent thereby to precipitate the composition (process A) and/or by evaporating the aqueous solvent off the solution (process B).
    Type: Grant
    Filed: July 28, 1978
    Date of Patent: December 30, 1980
    Assignee: Yamasa Shoyu Kabushiki Kaisha
    Inventors: Toshihisa Kawahara, Goro Motoki
  • Stabilized S-adenosyl-L-methionine preparations
    Patent number: 4109079
    Abstract: A stabilized dry S-adenosyl-L-methionine preparation is obtained by incorporating about 1 - 10 parts by weight of lithium in the form of a salt with 100 parts by weight of S-adenosyl-L-methionine or a low-toxicity salt thereof. According to the invention, instability of S-adenosyl-L-methionine or a salt thereof is substantially eliminated. The stabilized dry preparation is very useful as medical drugs and reagents for biochemical research.

  • Crystalline monosodium N.sup.6,2'-O-dibutyryl-adenosine-3',5'-cyclic monophosphate and production thereof
    Patent number: 4015066
    Abstract: Crystalline N.sup.6,2'-O-dibutyryl-adenosine-3',5'-cyclic monophosphate monosodium salt (DB.sub.c -AMP-N.sub.a), and a process for producing the same which may comprise the step of causing at least one solvent selected from an ether, ketone, and an ester, constituting a crystallizing organic solvent, to contact an alcoholic solution, aqueous alcoholic solution, or a simple aqueous solution of DB.sub.c -AMP-N.sub.a or may comprise the step of dissolving crude crystalline or amorphous DB.sub.c -AMP-N.sub.a in a mixture of an alcoholic solvent and the crystallizing organic solvent.
