摘要:
An object of the present invention is to provide a compound that can regulate plant growth. The compound selected from the group consisting of (A) and (B):(A) 3H-imidazo[4,5-d][1,2,3]triazin-4,6(5H,7H)-dione; and(B) 3-methyl-3H-imidazo[4,5-d][1,2,3]triazin-4,6(5H,7H)-dione;has a plant growth regulating action.
摘要:
Disclosed is a novel lectin which can bind specifically to an L-fucose α1→6 sugar chain. Also disclosed is use of the lectin. The L-fucose α1→6 specific lectin of the present invention is characterized in that: (1) the lectin is extracted from a basidiomycete or an ascomycete; (2) the lectin has a molecular weight by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of 4,000 to 40,000; and (3) the lectin has an affinity to an L-fucose α1→6 sugar chain, the affinity being represented by an association constant of 1.0×104M−1 or more (at 25 degrees C.). The lectin can be used for detecting an L-fucose α1→6 sugar chain specifically, and is effective for the purification of an L-fucose α1→6 sugar chain or a non L-fucose α1→6 sugar chain.

摘要:
A fat-soluble fraction extracted from the fruiting body of Hericium erinaceum is demonstrated to inhibit the neuronal toxicity of amyloid beta-peptide (Aβ) and induce the synthesis of nerve growth factor (NGF), and has great potential as an active ingredient for pharmaceutical products, health food products, food products and/or beverages to prevent and/or treat dementia, especially Alzheimer-type dementia. This invention is to provide the bioactive fraction and its preparation method.
