摘要:
The invention describes the possibility of the biofunctionalization of biomaterials, in particular implants, by their made-to-measure coating with synthesized cell- or tissue-selective RGD peptides which in vitro stimulate the adhesion of mainly those cell species which in each case are intended to accomplish the tissue integration of the appropriate biomaterial.
摘要:
The present invention relates to pharmaceutical compositions which contain at least one cyclopeptide of formula I (a)-(r):(a) cyclo(-Arg-Gly-Asp-D-Phe-Val-Ala);(b) cyclo(-Arg-Gly-Asp-D-Phe-Leu-Ala);(c) cyclo(-Arg-Gly-Asp-Phe-Val-D-Ala);(d) cyclo(-Arg-Gly-Asp-Phe-Leu-D-Ala);(e) cyclo(-Arg-Gly-Asp-D-Phe-Val-Gly);(f) cyclo(-Arg-Gly-Asp-D-Phe-Leu-Gly);(g) cyclo(-D-Arg-Gly-Asp-Phe-Val-Ala);(h) cyclo(-D-Arg-Gly-Asp-Phe-Val-Gly);(i) cyclo(-Arg-Gly-Asp-Phe-Pro-Gly);(j) cyclo(-Arg-Gly-Asp-Phe-D-Pro-Gly);(k) cyclo(-Arg-Gly-Asp-Phe-Pro-Ala);(l) cyclo(-Arg-Gly-Asp-Phe-D-Pro-Ala);(m) cyclo(-D-Arg-Gly-Asp-Phe-Val);(n) cyclo(-Arg-D-Ala-Asp-Phe-Val);(o) cyclo(-Arg-Gly-Asp-D-Phe-Val);(p) cyclo(-Arg-Ala-Asp-D-Phe-Val);(q) cyclo(-Arg-Gly-Asp-Phe-D-Val);(r) cyclo(-Arg-Gly-D-Asp-Phe-Val);or a salt thereof. The pharmaceutical compositions can be used as cell adhesion inhibitors, e.g., in the treatment of thrombosis, myocardial infarct, apoplexy, arteriosclerosis, inflammations, angina pectoris, and/or tumors.
