- Novel galactosylceramide analogs i3--dalcocereb mouth oxidase activator, skin external preparation and method for activating / 3--dalcocerebrosidase using the same
- the present invention relates to novel galactosylceramide analogs, an activator of / 3-dalcocere procidase, an external preparation for skin and a method of activating 3-dalcocerebrosidase using the same. More specifically, a specific galactosylceramide analogue activates (3-Dalcocereb oral lipase in the epidermis) 3-Dalcocerebrosidase activating agent, an external preparation for skin and / 3-Dalcocereb oral lipase Regarding the activation method, these are expected to improve rough skin and various skin diseases.
- Rough skin refers to dry skin in which exfoliation of keratinocytes is generally observed. Such rough skin elutes lipids between keratinocytes such as cholesterol, ceramide, and fatty acids, and degeneration of keratinocytes and proliferation of epidermal cells due to ultraviolet rays and detergents. It is caused by failure or the like. For the purpose of preventing or healing this rough skin, it supplies a keratinocyte intercellular lipid component or a synthetic keratinocyte lipid similar thereto, and epidermal cells such as epidermal growth factor (EGF). Researches such as administration of growth and keratinizing substances have been conducted.
- EGF epidermal growth factor
- the stratum corneum intercellular lipid consists of stratum corneum, which is biosynthesized in the cells of the spinous layer and the stratum granulosum. It is widespread.
- the lamellar granules are composed of dalcosylceramide, cholesterol, ceramide, phospholipids, etc., but darcosylceramide is scarcely contained in the intercellular lipids of the stratum corneum.
- darcosylceramide in lamellar granules is: It is hydrolyzed by prosidase and converted to ceramide, which takes a lamella structure.As a result, it improves the formation of a corneal cell-penetrating barrier as intercellular lipids and acts as a barrier to rough skin. it is conceivable that. For example, pathologically rough skin is observed in patients with Gaucher disease type 2 who have a genetic deficiency of / 3-Darcoseleb oral sidase completely. An abnormality is found in the structure.
- activators of 3-dalcocele foid oral lipase include SAP-2, which was previously found in the guinea pig spleen, and A1a and savosine C, which were found in the spleen of human goose disease. are known.
- these activators are proteins, and using them externally to activate epidermal i3-darcocerebrosidase poses a major problem in terms of transdermal absorption and safety. In addition, it is extremely difficult to isolate these proteins for industrial use in terms of cost.

- amide synthesis method a compound represented by the general formula (2) having two alkyl chains can be subjected to galactosylation reaction with amine, serine or cysteine whose carboxylic acid moiety is protected. After the introduction of carboxylic acid, one amino group is introduced by deprotection and condensation reaction of the amino group, then the protecting group of the carboxylic acid is removed, phosphorus trichloride is reacted to form an acid chloride, It can be produced by reacting with amine. Further, a compound represented by the general formula (1) having a single-chain compound can be produced in the same manner.
- the activator of the present invention is a galactosylceramide analog represented by the above general formula (1) or (2) as an active ingredient for improving rough skin.
- the activator for 3 / 3-dalcocele mouth and the external preparation for the skin may be in various dosage forms such as ointment, mouth lotion, emulsion, milk, cataplasm, pack, mist, foam, granule, powder, gel, etc. Can be.
- the external preparation for skin is intended for all skin of the body including the scalp, and includes bath salts.
- the substrate is not particularly limited as long as it is a commonly used external base.
- the final form can be cosmetics, pharmaceuticals, and quasi-drugs.
- the amount of the galactosylceramide analog to be added to the / 3--dalcocerebrosidase activator and the external preparation for skin is preferably 0.005 to 5.0% by mass based on the total amount of the composition. , 0.01 to 3.0% by mass. If the amount is less than 0.05% by mass, the effect of the present invention may not be sufficient. On the other hand, if the amount exceeds 5.0% by mass, the effect corresponding to the increase is not improved. There is. Example
- Example 1 Example 1
- the reaction mixture was extracted with ethyl acetate, washed with 2 mol / L hydrochloric acid and a saturated aqueous solution of sodium hydrogen carbonate, and the ethyl acetate layer was dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure.
