COMPLEXES NUCLEOPEPTIDIQUES, COMPOSITIONS COSMETOLOGIQUES ET PHARMACEUTIQUES LES CONTENANT ET UTILISATIONS

摘要

The invention concerns nucleopeptide complexes obtained by synthesis, comprising a sequence of at least three amino acids in the form of D, L or DL, said sequence being chemically or physically bound with xanthic acids, or their derivatives of general formula I: N-R1 - COOH, in which N represents one purine base containing 5 to 10 carbon atoms, R1 represents one C1 or C3 alkyl radical.
