Abstract

The invention is directed to the use of at least one peptide of formula: X-(Xaa1)n-Pro*-(Xaa2)m-Y (I) With: —n=0, 1 or 2; —m=0 or 1 and if m=0 then n≠0 —Xaa1 is: —An hydrophobic aminoacid selected from Alanine (Ala, A), Valine (Val, V), Methionine (Met, M), Leucine (Leu, L), Isoleucine (Ile, I), Phenylalanine (Phe, F), Proline (Pro, P) and analogues and derivatives thereof; —A polar aminoacid selected from Serine (Ser, S), Threonine (Thr, T), Tyrosine (Tyr, Y), Asparagine (Asn, N), Glutamine (Gln, Q) and analogues and derivatives thereof; —or Glycine (Gly, G); When n=2 the two aminoacids Xaa1 can be the same or different; —Xaa2 is: —An hydrophobic aminoacid selected from Alanine (Ala, A), Valine (Val, V), Methionine (Met, M), Leucine (Leu, L), Isoleucine (Ile, I), Phenylalanine (Phe, F), Proline (Pro, P) and analogues and derivatives thereof; —A basic aminoacid selected from Arginine (Arg, R), Lysine (Lys, K) and Histidine (His, H) and analogues and derivatives thereof; —Glycine (Gly, G) or Serine (Ser, S); —At the N terminal end of the peptide, X is selected from H, —CO—R1 and —SO2—R1; —At the C terminal end of the peptide, Y is selected from OH, OR1, NH2, NHR1 or NR1R2, R1 and R2…
