The invention relates to novel eucomic acid (2-(4-hydroxybenzyl)malic acid) derivatives or plant extracts comprising such derivatives, and also to cosmetic or dermatological compositions containing these compounds or these extracts, and to cosmetic care methods using said compositions. Exemplary compounds are represented by formula (I) below: in which, with the proviso that R1, R2 and R3 are not simultaneously a hydrogen atom, R1 and R3 each independently represent a hydrogen atom or a saturated or unsaturated, preferably C1-C12, hydrocarbon-based chain comprising an aromatic group, preferably a phenyl, said aromatic group being preferably substituted with a group comprising a sugar, preferably a monosaccharide or disaccharide, said chain optionally also comprising one or more heteroatoms preferably chosen from O, S and N, and R2 represents a hydrogen atom or a sugar, preferably a monosaccharide or disaccharide, said sugar being optionally substituted, in particular with a residue comprising a saturated or unsaturated, preferably C1-C12, hydrocarbon-based chain itself comprising an aromatic group, preferably a phenyl, said hydrocarbon-based chain optionally also comprising one or more heteroatoms preferably chosen from O, S and N.
摘要:
The present invention relates to methods for increasing the replication capacity of an influenza virus in cultured cells. More particularly, the present invention relates to a method for increasing the replication capacity of an influenza virus in a cell comprising the steps consisting of i) infecting said cell with said influenza virus and ii) culturing said infected cell with a least one molecule selected from the group consisting of Dibucaine, Aprindine, Amiloride, Mevinolin, Simvastatin, Promathazine, Pranlukast, Nimodipine, Ibutilide hemifumarate Salt, Risperidone and derivatives or analogues thereof.
摘要:
The invention relates to a solid coloring material obtained by precipitation, in an aqueous medium, of the reaction product of an alkali metal silicate with a colored complex obtained by reaction, in aqueous solution, of a hydrolysable tannin or of a plant extract comprising it with a salt of a metal cation. The invention also relates to a cosmetic composition intended for making up the skin or superficial body growths comprising this coloring material. It also relates to a method for making up the skin or superficial body growths comprising the topical application of this cosmetic composition.
摘要:
The invention relates to the use, in a cosmetic composition or for the production of a cosmetic composition, of an extract of an exudate of the plant Daniellia oliveri, said exudate being at least partially made up of the oleoresin of said plant.It relates most particularly to the use of this extract as a cosmetic agent for modifying the surface of the skin by giving it a smoother appearance through a reduction in the depth of the wrinkles and/or fine lines and/or by providing it with a re-plumping effect.It also relates to a cosmetic care method for modifying the surface of the skin by giving it a smoother appearance through a reduction in the depth of the wrinkles and fine lines and/or by providing it with a re-plumping effect, comprising the application, to the areas of the skin in question, of a cosmetic composition containing this extract.
摘要:
The present invention relates to a novel use of alkyl glycosides and of mixtures of alkyl glycosides having anti-ageing and/or calming properties as active agents in cosmetic compositions, and to methods of cosmetic care using the said compositions.
摘要:
The disclosure relates to a method for in vivo differentiation of monocytes in mature dendritic cells, wherein a) monocytes are provided in an appropriate culture medium, b) the monocycles are differentiated in dendritic cells in the presence of a differentiation factor, c) L-α-lysophosphatidylcholine is added to the medium and mature dendritic cells are obtained. The disclosure also relates to the use of at least one inhibitor of L-α-lysophosphatidylcholine in the production of a medicament for the prevention of an inflammation and/or in order to combat an inflammatory disease and/or autoimmune disease.
摘要:
The invention concerns a method for differentiating precursor cells into mature dendritic cells, comprising placing the precursor cells in a medium suitable for their differentiation and adding to the medium, in a predetermined amount, at least one fraction of oxidized lipoproteins selected among oxidized very low density lipoproteins (VLDLs) and/or oxidized intermediate density lipoproteins (IDLs) and/or oxidized low density lipoproteins (LDLs). The precursor cells are preferably monocytes.
摘要:
The invention relates to the use of a Rhodiola crenulata extract, via the topical route, for increasing the energy metabolism of the cutaneous tissues of a subject. The invention relates notably to topical compositions which comprise an active agent for increasing the energy metabolism of the cutaneous tissues of a subject, said active agent being a Rhodiola crenulata extract. The present invention enables making a cosmetic care such as fighting against, or slowing down or preventing the loosening of the cutaneous tissue, increasing the plasticity of the cutaneous tissue, exerting an anti-wrinkle effect or slowing down or preventing the appearance of wrinkles, fighting against, slowing down or preventing the appearance of acne, exerting a depigmenting effect of the cutaneous tissue, in particular of the skin, and promoting desquamation of the cutaneous tissue (or “peeling”).
摘要:
Products of formula (I) extracted from a plant of the genus Commiphora, particularly the Commiphora mukul plant, wherein R is (a) a CH2OH grouping, (b) a COOH grouping, and salts or esters thereof are described. These products and the extracts containing them are effective cosmetic agents against wrinkles.
