ABSTRACT:
The purpose of the invention concerns a family of pseudodipeptides which are coupling products between tryptamine, an indole-primary amine, and a selection of alpha-amino acids, the said pseudodipeptides having the following general formula (I):in which:R1represents a hydrogen atom, an acyl or acyloxy radical,R2represents the side chain of an alpha-amino acid chosen among L-glutamic acid, L-arginine, L-cysteine, L-methionine, L-histidine, L-tryptophan, L-tyrosine.The present invention also concerns the process for the preparation of said products as well as their applications in neurocosmetic compositions or as active substances on the cutaneous nervous system.
