摘要:
The invention relates to the use of compounds of formula (I) R—N1-spermidine, i.e. 1.4-butanediamine,N-(3-aminopropyl)-N1—R, (I) H2N —(CH2)3—N1(R)—(CH2)4—NH2, as such or in the form of pharmaceutically acceptable derivatives, as active principle in a cosmetic or pharmaceutical composition for resisting the effects of skin ageing through an anti-inflammatory action, by topical administration. Such compounds also have an antioxidant activity against oxygen free radicals (ROS) comparable with that of α-tocopherol.
摘要:
The invention relates to the 4-((2E,4E,6E)-octa-2,6,4-trienamid)butanoic acid; its use in the therapeutic and cosmetic field for topical application to the skin to achieve a combined antioxidant activity against ROS together with an anti-inflammatory effect and an effect of promoting the production of hyaluronic acid, so as to oppose at the same time the oxidizing action of free radicals and inflammatory effects, in order to preserve the physiological conditions of human epidermis and skin homeostasis and prevent skin aging (anti-aging); the compositions for therapeutic and cosmetic use which comprise 4-((2E,4E,6E)-octa-2,6,4-trienamid)butanoic acid as active ingredient, formulated with excipients for topical use suitable for local administration on the skin.
摘要:
The invention concerns the use of compounds with formula (I) R—N1-spermidine, or 1,4-butandiamin,N-(3-amino propyl)-N1-R, (I) H2N—(CH2)3—N1(R)—(CH2)4—NH2 either as such or in the form of a pharmaceutically acceptable derivative, such as an active ingredient in a cosmetic composition designed to promote hair pigmentation, particularly the pigmentation of the shaft, and a composition suitable to achieve said pigmentation effect and containing said active ingredient, either as such or in the form of a pharmaceutically acceptable derivative such as a salt, for topical administration.
摘要:
The invention relates to 2,4,6-octatrienoic acid derivative compounds having general formula (I) (CH3—CH═CH—CH═CH—CH═CH—CO—O—)n—R (I) consisting of esters wherein n=1, 2, 3 and wherein R is selected from alkyl, aryl or cycloalkyl of a polyol, phenol or phenolic acid; or consisting of a salt wherein n=1 and R=arginine, as active ingredients in a pharmaceutical or cosmetic composition having a combined antioxidant activity against free radicals together with an anti-inflammatory action.
摘要:
The present invention relates to the use of a plant extract from the genus Galeopsis species tetrahit or a composition that contains it to stimulate hair growth or improve the appearance or hair fullness. The composition containing the plant extract is applied in both cosmetic and medical-trichological fields and can be applied topically on the scalp or administered orally.
摘要:
The invention relates to compounds having general formula (I): where R═H, CH2—OH, CH2—O—CO—CH3, CH2—O—CO—Ph (Ph=phenyl) R′═H, CH2—O—CO—CH3, CH2—O—CO-Ph (Ph=phenyl) Ar=phenyl, 3-methoxy-4-hydroxy phenyl, 2-furyl. These are compounds having antioxidant activity against free radicals together with anti-inflammatory activity, the compounds being useful as active ingredients for the preparation of pharmaceutical dermatological or cosmetic compositions for skin care.
摘要:
The present invention relates to a composition for pharmaceutical, nutritional or cosmetic use, suitable to preserve the physiological condition and health of skin and hair and to reestablish their regenerative functions, characterized in that it comprises a mixture of carnitine, caffeine and arginine as active principle, as such or as derivatives, such as pharmacologically acceptable salts. The effect of preserving the physiologic condition and health of skin and hair, and of reestablishing their regenerative functions is mainly achieved through an increase in ATP production by skin and hair cells.
