Definitions

  • the present invention relates to the cosmetic, dermatological or therapeutic use of certain menthyl carbamate compounds of formula (I) given below, preferably as anti-cellulite actives.
  • the invention further relates to compositions and cosmetic, dermatological or therapeutic products comprising such compounds of formula (I), which are preferably suitable for the prophylaxis (prevention) and cosmetic treatment (combating) of cellulite in human beings, corresponding methods and to certain novel compounds of formula (I).
  • Cellulite is also known under the synonyms protrusio cutis and colloquially as orange peel skin. It is a cosmetic-aesthetic problem which is accompanied by the formation of dimples and indentations of the skin and nodule formation of the subcutaneous fat tissue. Cellulite can occur on any part of the human body, but the outer side and the back of the thighs as well as the buttocks are most frequently affected. Breasts, lower stomach, upper arms or neck are also sometimes affected by cellulite. Cellulite may be regularly found on parts of the human body with excessive fat deposits, but overweight is not a prerequisite for its occurrence. Slim women increasingly also have pronounced cellulite symptoms. However, there is probably a correlation between the severity of the cellulite and the percentage of fat in the tissue.
  • the gender-specific anatomic structure of the skin of human beings has a great influence on the development of cellulite.
  • cellulite can only seldom be observed in men, while, on the other hand, about 80% - 90% of all women are affected, in particular Caucasian women.
  • the structure of the dermis in particular, has an effect on the skin relief.
  • the fat chambers in men when the skin is pressed together, are held back by intersecting connective tissue septa and the clamp-like enclosure of the fat cells connected therewith.
  • the fat chambers separated from one another in a tubular manner which are enclosed by actinomorphically extending connective tissue septa, bulge up when being pressed together.
  • the visible pattern of the cellulite is based on an increase in fat cushions in the subcutis and a reduction in the circulation conditions in the blood and lymph vessels.
  • the cause is therefore partly a predisposed weakening of the connective tissue with simultaneous occurrence of enlarged fat cell chambers with stress, sports activity, smoking, pregnancies and female hormones (oestrogen and progesterone) playing a part, in addition to genetic factors.
  • Cellulitis is to be clearly separated and distinguished from the cosmetic phenomenon of cellulite.
  • Cellulitis is a bacterial infection of the subcutaneous tissue, which in many cases may be a serious illness, and in contrast to cellulite, has to be treated therapeutically.
  • a cosmetic use or a cosmetic method is free of any therapeutic (side) effects.
  • a therapeutic or pharmaceutical use or method is considered as medical treatment, optionally with cosmetic (side) effects.
  • the conventional treatment methods for cellulite attempt to encourage the blood circulation of the relevant skin parts and to positively influence the connective tissue structure, for example by massage, lymph drainage, diet, sport, magnetic fields or else liposuction (removing fat by suction).
  • Fat metabolism in the fat tissue of humans in order to reduce the stored lipid quantity, can in principle be regulated by three Routes:
  • preadipocytes The differentiation of the precursor cells of the fat cells called preadipocytes to the real fat cells, called adipocytes, which may store triglycerides, can be inhibited. Expressed more simply, an inhibition of Route (i) prevents the build up of cellulite in that the number of fat cells does not increase. This process of differentiation from preadipocytes to adipocytes is called adipogenesis.
  • triglycerides in the adipocytes can be prevented or inhibited.
  • an inhibition of Route (ii) prevents the storage of further triglycerides (fats) in the cell and existing fat cells do not store any new fat. Owing to the natural fat metabolism, when Route (ii) is inhibited, the fat content in the cell decreases.
  • the differentiation of cells is the changing of the control of the gene activity of a cell so that various protein stores are provided in the cells by means of transcription and protein biosynthesis and the cells differ according to appearance and function.
  • adipocytes only express enzymes, which are necessary for the storing of fats, after differentiation.
  • the undifferentiated preadipocytes these enzymes are not expressed or only to a very small extent.
  • Cosmetic preparations which have the prophylaxis and treatment of cellulite as a goal have already been proposed in the literature. They mostly influence adipose tissue or adipocytes by a specific activity.
  • EP 1 234 572 describes a cosmetic preparation of at least one isoflavone aglycone, in particular genistein and/or daidzein, for treating cellulite.
  • the isoflavone aglycone is in this case combined with an algae extract.
  • Genistein is described there as an active ingredient, which inhibits the multiplication of precursor fat cells and in addition the enzyme phosphodiesterase.
  • a cosmetic preparation of certain biochinones and isoflavonoids, preferably genistein, are described for the prophylaxis of cellulite in DE 10 2004 032 837. It is maintained that the effect of this preparation takes place by means of an improvement in the cell metabolism. It cannot be seen there which mechanism of the cell metabolism is improved. It can also not be inferred there whether the fat tissue is influenced by the cosmetic preparation.
  • isoflavones Preparations containing certain isoflavones are also described in DE 100 09 423, the isoflavones being described as materials with an anti-oestrogen effect and used because of this effect. Daidzein, genistein, glycitein, formononetin and others are preferred isofla- vones there.
  • WO 2006/063714 teaches compositions for topical administration, containing a PDE3 inhibitor as active ingredient, for use in the treatment of cellulite and proposes pharmaceutical compositions comprising drugs like anagrelide, cilostazol, pimobendan, milrinone, amrinone, olprinone, enoximone, cilostamide, vesnarinone and trequinsin.
  • R 1 denotes hydrogen or an organic radical having 1 to 14 carbon atoms
  • R 2 denotes an organic radical having 1 to 14 carbon atoms
  • R 1 and R 2 are covalently bonded to one another, preferably so that a 3 to 8 membered ring is formed.
  • the compounds of formula (I) show a pronounced effect in the treatment of cellulite, recognisably by means of echographic determination of the subcutis layer thickness, in particular to prevent the increased formation of fat stores in the skin and/or cellulite, in that the lipid content in the human subcutaneous fat tissue is reduced.
  • the invention therefore relates to cosmetic preparations (compositions) containing a corresponding effective quantity of one or more compounds of formula (I), in particular for the topical treatment and prevention of increased formation of fat stores in the skin and/or cellulite
  • the compounds of formula (I) structurally belong to the group of menthyl carbamates.
  • a "flat" structural formula i.e. a graphical formula which does not convey any stereochemical information and gives no concrete information about the three-dimensional structure thereof, relates to and includes all stereoisomers of said structural formula.

  • (+)-lsomenthol (lie) (+)-Neoisomenthol (Nd)
  • the enantiomers (Na) to (Nd) and their optical antipodes may, for example, be obtained by hydrogenation of thymol (e.g. WO 2004/018398 and the references cited therein) or via cyclization of citronellal to the corresponding isopulegol-isomers and subsequent hydrogenation.
  • the menthol isomers can be separated via accurate distillation (for more details on manufacturing and separation of menthol isomers see "Common Fragrance and Flavor Materials", 4th Edition, Wiley-VCH, Weinheim 2001 , 52-55).
