    Abstract: PROBLEM TO BE SOLVED: To obtain a preventive for skin aging, capable of preventing and improving symptoms caused by aging of skin, by including a mercaptopropionamide derivative. SOLUTION: This medicine comprises a mercaptopropionamide derivative of the formula (R is H or acyl; R is H or a hydrocarbon; R is H, carboxyl, an alkoxycarbonyl, a hydrocarbon, a heterocyclic or an acyl; (n) is 1-20) or its salt as an active ingredient. The medicine is further formulated with an ultraviolet absorber and/or an ultraviolet controller to preferably prepare a skin preparation for external use. The formulated amount of the compound of the formula in the case of preparing a skin preparation for external use is preferably 0.0001-5 wt.% based on the whole composition. The compound of the formula has inhibitory action on a metal-dependent elastin decomposing enzyme and is capable of effectively controlling change caused by aging of skin such as occurrence of wrinkle and slackening and reduction in tension.

    Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound in high yield with industrial advantage by carrying out the two-phase reaction comprising the aqueous phase and the organic phase, when 3-alkylflavanone derivative is oxidized with hydrogen peroxide. SOLUTION: (A) 3-Alkylflavanone derivative of formula I (R is a 1-12C alkyl; R and R are each a halogen or 1-12C alkyl which may be substituted with a 1-12C alkoxy group, H, hydroxy group, cyano, a halogen) is oxidized with (B) hydrogen peroxide. In this reaction, a two phase system of an aqueous phase and an organic phase or a three phase system of an aqueous phase, an organic phase and a solid phase is used to prepare (C) a 3-alkylflavanol derivative of formula II. The aqueous phase and the organic phase preferably comprises water and an organic solvent immiscible with water, for example, n-propanol, n-butanol, toluene, xylene, acetone or the like. Thus, a compound that is useful as a hair-growing or hair tonic agent can be produced with industrial advantage.

    Abstract: PROBLEM TO BE SOLVED: To obtain a hair growth-inhibiting agent containing a specific phthalazinone compound as an active ingredient, capable of effectively inhibiting the growth of hair to reduce the number of hair-removing treatments, and excellent in safety over a long period. SOLUTION: This hair growth-inhibiting agent contains a phthalazinone compound of formula I (R is a 1-4C alkyl; R is a hydroxyalkyl, an alkenyl, phenyl) or a benzoxazinone compound of formula II as an active ingredient. The active ingredient of the hair growth-inhibiting agent is preferably added to a cosmetic in an amount of 0.001-3wt.%.

    Abstract: PROBLEM TO BE SOLVED: To obtain the subject suppressant, comprising mollugin represented by a specific formula or its derivative as an active ingredient, having a low cytotoxicity and excellent suppressing actions on cell adhesion and useful as a suppressant for cancer metastasis, an immunosuppressant, etc. SOLUTION: This suppresant for cell adhesion comprises mollugin represented by the formula (R and R are each hydroxyl or an alkoxy) or its derivative as an active ingredient. Furthermore, the compound is preferably prepared by pulverizing, e.g. Rubia tinctorum L., extracting the pulverized Rubia tinctorum L. with a solvent such as methanol, removing the solvent from the resultant extract solution, dissolving the obtained residue in a solvent such as methanol, further treating the resultant solution with benzene, etc., as an eluting solvent by a column chromatography and then carrying out the fractionation. The daily oral dose thereof is preferably within the range of 10-300mg for an adult administered in one to several divided portions when administering the active ingredient as a medicine to a human.

    Abstract: PURPOSE: To obtain the subject agent containing an extract of Hamamelisvirginiana L. as an active component, excellent in suppressing activity against wrinkles of the skin formed by the irradiation of ultraviolet and useful as a skin external agent for preventing wrinkles. CONSTITUTION: This agent contains an extract of Hamamelisvirginiana L. as an active component preferably in a content of 0.001-5wt.% in terms of a dry solid material. The extract is preferably obtained by adding 100g of dry crashed material of Hamamelisvirginiana L. with 1000ml of 50v/v% ethanol aqueous solution, extracting it for 3 days at room temperature while it is stirred at intervals, subsequently filtering the extraction mixture, allowing the filtrate to stand at 5 deg.C for 3days and filtering this solution again to obtain a clear filtrate. Further, the above wrinkle-suppressing agent is preferably incorporated with a component selected from an anti-inflammatory agent such as glycyrrhizic acid, an extract of one of various kinds of plants other than Hamamelisvirginiana L., a singlet oxygen-removing agent and an antioxidant since this enhances the wrinkle-suppressing effect.
