Abstract: A polymeric prodrug composition including a hydrogel, a biologically active moiety and a reversible prodrug linker. The prodrug linker covalently links the hydrogel and the biologically active moiety at a position and the hydrogel has a plurality of pores with openings on its surface. The diameter of the pores is larger than that of the biologically active moiety at least at all points of the pore between at least one of the openings and the position of the biologically active moiety.

Abstract: Compounds of the formula I B-Q-X1 and processes for their preparation, wherein B, Q and X, are as defined in the application, and salts thereof as integrin inhibitors for the treatment of diseases, defects and inflammation caused by implants and of osteolytic diseases, such as osteoporosis, thrombosis, cardiac infarction and arteriosclerosis, and for the acceleration and strengthening of the integration process of the implant or of the biocompatible surface into the tissue.

Abstract: The invention relates to compounds of formula (I) B-Q-X1, wherein B is a bioactive, cell adhesive mediating molecule, selected from the group (i) and Thr-Trp-Tyr-Lys-Ile-Ala-Phe-Gln-Arg-Asn-Arg-Lys (ii), Trp-Tyr-Lys-Ile-Ala-Phe-Gln-Arg-Asn-Arg-Lys (iii), Tyr-Lys-Ile-Ala-Phe-Gln-Arg-Asn-Arg-Lys (iv), Thr-Trp-Tyr-Lys-Ile-Ala-Phe-Gln-Arg-Asn-Arg (v), Thr-Trp-Tyr-Lys-Ile-Ala-Phe-Gln-Arg-Asn (vi), Thr-Trp-Tyr-Lys-Ile-Ala-Phe-Gln-Arg (vii), wherein (i) X, Y, Z, R2, R3, R4, A, Ar, Hal, Het, Het1, n, m, o, p, q, s, t have the meanings cited in claim 1, Q is absent or is an organic spacer molecule, X1 is an anchor molecule selected from the group cited in claim 1, and the salts thereof, which can be used as integrin inhibitors particularly for treatment of illness, deficiencies and inflammations caused by implants and osteolytic illnesses such as osteoporosis, thrombosis, cardiac infarction and arteriosclerosis, in addition to the acceleration and strengthening of the integration process of implants or the biocompatib

Abstract: The invention relates to compounds of formula (1) I-Q-X1, wherein B is bioactive cell adhesive mediating molecule. Q is absent or is an inorganic spacer molecule and X1 is an anchor molecule, selected from the group Lys.(CO—CH —(CH2)n—PO3H2)2(I)-Lys[-Lys-(CO—CH2—(CH2)a—PO3H2)2]2(ii) or -Lys-(Lys[-Lys-(CO—CH2—(CH2)n—PO3H2]2 (iii), and n independently represents 0, 1, 2 or 3, wherein a free amino group of group B is linked in peptide form to a free carboxyl group of the spacer molecule Q or of the anchor molecule X1 or a free amino group of the radical Q is linked in peptide form to a free carboxyl group of the radical X1. The invention also relates to the salts thereof.
