摘要:
The invention concerns a bioactive prosthesis comprising a support coated with a polymer layer with reactive functions, and a bioactive substance fixed on the prosthesis via said reactive functions so as to be gradually released on a site for implanting the prosthesis. Such prostheses are useful in the field of cardiology to avoid for example restenosis resulting from implantation of stents in coronary arteries.

摘要:
The invention concerns cyclic peptides, the method for preparing them and their use as angiogenesis inhibitor or activator. Said cyclic peptides comprise the following peptide sequence: -Arg-Ile-Lys-Pro-Gln-Gly-. They can also be used in angiogenesis inhibiting systems comprising a support (1) whereon the cyclic peptide is fixed by an organic spacer arm (3), optionally provided with a motif (4) capable of being cleaved by an enzymatic system.
