Definitions
- the present invention relates to topically applicable agents or compositions, in particular
- Skin lightening agents or compositions for lightening the skin containing amidino or guanidinoalkyl disulfides, and the use of these compounds and of the compositions according to the invention for lightening the skin color, for depigmenting age spots and for compensating for irregularities in skin coloration.
- Skin-lightening agents have an effect on melanin metabolism or melanin metabolism.
- the usually brown to black-colored melanins are formed in the melanocytes of the skin, transferred to the keratinocytes and cause the color of the skin or hair.
- the brown-black Eumelanine are in mammals mainly of hydroxy-substituted aromatic amino acids such as L-tyrosine and L-DOPA, the yellow to red pheomelanins additionally formed from sulfur-containing molecules such as cysteine (Cosmetics & Toiletries 1996, 111 (5), 43-51).
- L-tyrosine the copper-containing key enzyme tyrosinase L-3,4-dihydroxyphenylalanine (L-DOPA) is formed, which in turn is oxidized by the tyrosinase via the red-brown colored dopaquinone to melanin.
- L-DOPA copper-containing key enzyme tyrosinase L-3,4-dihydroxyphenylalanine
- Undecylenoylphenylalanine, Hexapeptide-2 and Broussonetia Extract Powders need to be dosed relatively high to provide sufficient skin bleaching.
- cystamine (2-aminoethyl) disulphide] as a non-toxic active substance is capable of effectively and reversibly depigmenting human melanoma cells as well as normal melanocytes (J. Invest. Dermatol., 2000, 21-27).
- the effect of cystamine is based on the fact that in a first step, a reduction to cysteamine occurs, which then reacts with products of tyrosinase activity reactions and so the melanin synthesis, especially that of brown / black eumelanin in derogation.
- the object of the present invention is to find inexpensive, easily prepared, highly effective, stable non-tyrosinase inhibiting agents which can be used in skin lightening agents.
- the present invention relates to a topically applicable
- Agent or a topically applicable composition, in particular for use as a skin whitening agent or composition for whitening the skin color and for bleaching age and pigmentation, characterized in that it comprises an effective amount of at least one compound of general formula (I) or Mixture of such compounds and / or an acid addition salt thereof contains
- X is NH or a direct bond and n is 2, 3 or 4, preferably 2 or 3, mean.

- the guanidino compounds can be obtained on the one hand by amidation of the corresponding amino derivatives, as described, for example, in British Journal of Pharmacology 118, 1659-1668 (1996). On the other hand, they are accessible from aminoalkylisothiouronium salts by rearrangement and subsequent oxidation [Chem. Pharm. Bull. 14 (11), 1193-1201 (1966)].
- the amidino derivatives can be prepared by reacting the cyanoalkyl disulfides, e.g. in WO03 / 072559 and according to the literature cited therein.
