Abstract: There are provided an autophagy activator comprising, as an active ingredient, an inositol derivative in which a saccharide is bound to inositol, and a composition for activating autophagy comprising the autophagy activator and a pharmaceutically acceptable carrier.

Abstract: There are provided an autophagy activator comprising methyl hesperidin as an active ingredient, and a composition for activating autophagy containing the autophagy activator and a pharmaceutically acceptable carrier.

Abstract: A cancer cell proliferation suppression agent containing, as an active ingredient, an inositol derivative in which a sugar is bound to inositol is provided. Furthermore, a composition for suppressing proliferation of cancer cells containing the above-mentioned cancer cell proliferation suppression agent and a pharmaceutically acceptable carrier is provided.

Abstract: A mixture of inositol derivatives in which a sugar is bonded to inositol includes an inositol derivative (A10) in which total sugars bonded to one inositol molecule is 10 or more in terms of monosaccharide units. In addition, a mixture of inositol derivatives in which a sugar is bonded to inositol includes 5% by mass or more of an inositol derivative (A7), in which total sugars bonded to one inositol molecule is 7 or more in terms of monosaccharide units, with respect to a total amount of inositol derivatives (100% by mass).

Abstract: An agent for protection against atmospheric pollutants containing a tocopherol phosphate ester or a salt thereof as an active ingredient is provided. A composition for protection against atmospheric pollutants containing the above-mentioned agent for protection against atmospheric pollutants and a pharmaceutically acceptable carrier is further provided.

Abstract: The present invention provides an agent containing an orotic acid derivative that has high solubility in solvent and has superior physiological activity. The agent of the present invention is a melanin production inhibitor, whitening agent, fibroblast activator, collagen and/or elastin production promoter or wrinkle ameliorant containing as an active ingredient thereof an orotic acid derivative represented by the following general formula (1) or a salt thereof. In formula (1), R preferably represents a side chain of glutamic acid, glycine, histidine or aspartic acid. [In formula (1), R represents a side chain of a naturally-occurring amino acid and R may form, together with a nitrogen atom adjacent thereto through a single carbon atom, a hetero ring.

Abstract: Provided is an anti-aging agent for skin which contains, as an active component, an inositol derivative in which a monosaccharide or an oligosaccharide is bonded to inositol, in which a total amount of the monosaccharide or the oligosaccharide bonded to one inositol molecule is 2 or greater in terms of monosaccharide unit.
