摘要:
Disclosed herein is a process for promoting the integration of a biocompatible device or implant into a tissue of a subject. The process comprises covalently bonding to the surface of the device or implant a compound of the formula I R-Q-X I wherein R is cyclo-(Arg-Gly-Asp-Z), and wherein Q, X and Z are as defined herein.
摘要:
Compounds of the formula I R—Q—X I, in which R, Q, and X are as defined herein, can be used as integrin inhibitors. In particular, compounds of formula I are suitable for the treatment of disorders caused by implants, defects, inflammations and of osteolytic disorders such as osteoporosis, thrombosis, cardiac infarct and arteriosclerosis. These compounds are also suitable for the acceleration and reinforcement of the integration process of implants and biocompatible surfaces into tissue.
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 invention relates to compounds of formula (1) B-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—CH2—(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. The inventive compounds can be used as integrin inhibitors for the treatment of illnesses, deficiencies, 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 biocompatible surface in tissue.

摘要:
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.
摘要:
The invention relates to implant materials that are based on hydraulic cements in the form of one or more pastes, suspensions or dispersions that contain mineral and/or organic and/or organomineral solids and that react, when combined or when reacted with an aqueous liquid, to a solid in a cement-type initiation reaction. The invention also relates to the use of these materials as technical, medical-technical and/or pharmaceutical products, especially as bone cements, bone replacement materials, bone glues, dental filling materials and implantable active ingredient carriers. The implant materials according to the invention in the form of one or more pastes, suspensions or dispersions that contain mineral and/or organic and/or organomineral solids are formulated in an excipient liquid in such a manner that the pastes, suspensions or dispersions are stable in storage at normal conditions over a prolonged period of time and that they react, when combined with an aqueous liquid or when added to an aqueous liquid, in a cement-type initiation reaction and set to a solid. The excipient liquid of the mineral paste, suspension or dispersion is substantially water-free, and water immiscible or insoluble or hardly soluble in water in the chemical sense.

The invention relates to a process for the preparation of bone cements comprising active compound and to bone replacement materials or implantable drug depots produced therefrom. The bone cement is composed of a solid component and a liquid component. The liquid component is dissolved in an organic solvent whose proportion does not exceed 50% by weight based on the liquid component, and this solution is mixed with the solid component.
摘要:
The invention relates to methods for producing a partial or complete bioactive coating of an iron and/or zinc based metal implant material with calcium phosphates, a bioactively coated iron and/or zinc based metal implant, which is partially or completely coated with calcium phosphates, and bone implants containing an implant material according to the invention. In order to produce the coating according to the invention, iron and/or zinc based metal implant materials are brought in contact with acidic aqueous solutions, which have a pH value of 6.0 or less and contain calcium phosphates, whereby a calcium phosphate layer is deposited on the surface of the implant materials. The iron and/or zinc based metal implant materials, which are used in methods according to the invention, are materials consisting of base iron alloys or pure iron or materials that contain other substances, which are coated with pure iron, with a base iron alloy and/or with zinc.
