Energy metabolism activator in muscle cells

摘要

The present invention provides a novel muscle energy metabolism activator and the like, and further provides a composition that can be taken as a medicine or food. The technical features of the present invention for solving the above-described problems are as follows. (1) A sugar containing at least one selected from 5-Hydroxy-3,7-dimethoxyflavone, Techtochrysin, 3,7,4'-Trimethylkaempferol, Retusine, Pentamethylquercetin, Trimethylapigenin, Tetramethylkaempferol, and 5,7-dimethoxyflavone Transporter (GLUT4) gene expression promoter. (2) A sugar transporter (GLUT4) gene expression promoter comprising at least one of Techtochrysin and 5,7-dimethoxyflavone as an active ingredient. (3) The following chemical formula (1): wherein R1 and R2 are each hydrogen or an alkyl group having 1 to 3 carbon atoms. ] A sugar transporter (GLUT4) gene expression promoter in muscle cells consisting of any one of the compounds represented by
