摘要

The present invention relates to peptides of general formula (I) that are capable of regulating fibrillogenesis, stereoisomers thereof and mixtures thereof, which may or may not be racemic, and the cosmetically or dermopharmaceutically acceptable salts thereof, in which Z is alanyl, allo-isoleucyl, glycyl, isoleucyl, isoseryl, isovalyl, leucyl, norleucyl, norvalyl, prolyl, seryl, threonyl, allo-threonyl or valyl; n and m may vary between 1 and 5; AA is selected from the group formed by natural amino acids encoded in their L- or D- form and non-encoded amino acids; x and y may vary between 0 and 2; R1 is H or an alkyl, aryl, aralkyl or acyl group; and R2 is amino, hydroxyl or thiol, all these possibly being substituted with aliphatic or cyclic groups. A method for obtaining cosmetic or dermopharmaceutical compositions containing them and use thereof for treating the skin, preferably those skin conditions that require the regulation of fibrillogenesis, such as aging and/or the softening of the appearance of scars.
