USE OF MULTIVALENT SYNTHETIC LIGANDS OF SURFACE NUCLEOLIN FOR TREATING CANCER OR INFLAMMATION

摘要

The present invention relates to the use of a polyvalent synthetic compound comprising a support on which at least 3 pseudopeptide units are grafted, said compound being of formula (I), in which each X independently represents any amino acid; Y₁ and Y₂ are selected independently from amino acids having a basic side chain; Z is selected from a proline, optionally substituted at ?, - or ..; a natural or non-natural N-alkylamino acid; a dialkylamino acid; a cyclic dialkylamino acid; pipecolic acid or a derivative thereof; n and i independently are 0 or 1; m is an integer between 0 and 3; k is an integer greater than or equal to 3; and ? represents a modified peptide bond which is significantly more resistant to at least one protease than a standard peptide bond, for preparing a medicament intended for treating a disease involving deregulation of cell proliferation and/or of angiogenesis, and preferably acting as a surface nucleolin ligand, or for treating inflammatory diseases.
