, (2007/10/06)
PROBLEM TO BE SOLVED: To provide a composition for ameliorating allergic constitution naturally ingestible in daily life. SOLUTION: The composition for ameliorating the allergic constitution comprises a galactooligosaccharide as a main ingredient. Furthermore, a food and drink uses the composition. Since the galactooligosaccharide is already widely used in heath-oriented foods such as a specific food for health and is a material in which the safety is sufficiently established, the galactooligosaccharide is naturally ingestible over a long period in the daily life.

Synergistic compositions for the selective control of tumor tissue
-
, (2008/06/13)
According to the invention, compositions are made available which have a strong cytotoxic effect which is largely selective on tumor tissue. The invention is based on the fact that certain benzoic acid derivatives have a strong synergistic effect as a mixture and destroy cancer cells selectively in a pH range of 7 or below, such as from 6.5 to 7.

Cobalt(II)-Catalyzed Reaction of Aldehydes with Acetic Anhydride under an Oxygen Atmosphere: Scope and Mechanism

The reaction of aldehydes with acetic anhydride in the presence of catalytic cobalt(II) chloride under an oxygen atmosphere at ambient temperature is dependent upon the reaction medium.Aliphatic aldehydes react in acetonitrile to give 1,2-diones whereas the aromatic aldehydes are acylated to yield the corresponding acylals.On the other hand, carboxylic acids are obtained from aliphatic and aromatic aldehydes by conducting the reaction in dichloroethane or benzene.Cobalt(II) chloride in acetonitrile catalyzes the conversion of aliphatic aldehydes to the correspondinganhydrides in the absence of acetic anhydride whereas aromatic aldehydes remain largely unaffected under these conditions.A preliminary mechanistic study in three different solvents (i.e. acetonitrile, dichloroethane, and DMF) has revealed that in acetonitrile and in the presence of acetic anhydride, aliphatic aldehydes behave differently than aromatic aldehydes.Some trapping experiments using methyl acrylate and stilbene have been conducted to demonstrate the occurence of an acyl cobalt and peroxyacyl cobalt intermediate during these reactions.
Cobalt (II) catalyzed oxidation of aldehydes to carboxylic acid with molecular oxygen
Bhatia, Beena,Iqbal, Javed
, p. 7961 - 7964 (2007/10/02)
A variety of aromatic and some aliphatic aldehydes are efficiently transformed to the corresponding carboxylic acid in presence of catalytic amount of Cobalt (II) chloride, molecular oxygen and acetic anhydride at room temperature. Phenolic aldehydes undergo acylative oxidation to give the corresponding acylated carboxylic acid.
A New Method for the Degradation of Anthocyanidins, Flavones, Chalcones, and Coumarins
Mentlein, Rolf,Vowinkel, Erich,Wolf, Bernd
, p. 401 - 406 (2007/10/02)
After transformation into the corresponding chalcone or flavenol acetates anthocyanidins are oxidatively cleaved with ruthenium tetroxide to yield benzoic acid derivatives of the rings A and B.Flavones, chalcones, and coumarins are degradated by the same method.
