<p>The present invention relates to a new utilization of a peptide substance, said utilization being characterized in that use is made of a peptide substance comprising in its structure: (a) a first fragment having the formula Asx-A1-A2, (F1), wherein Asx is Asp ou Asn, A1 is Gly, MeGly, EtGly ou Aib, A2 is Arg, Dbu, His, Lys ou Orn, and (b) a second fragment of formula: A3-Cys-A4-Asx, (F2), wherein A3 is Leu, Ile, Nle, Val, Nva, Ahe, Acp or Cle, A4 is Leu, Ile, Nle, Val, Nva, Ahe, Acp or Cle, and Asx is Asp or Asn as indicated hereabove, the second fragment (F2) being closer to the terminal C-extremity than the first fragment (F1), for the preparation of a cytoprotector medicament useful against cytotoxic agressions. Amongst said peptide substances, those which are new are also useful as anti-megacaryocytic agents.</p> |
