摘要:
Die Erfindung betrifft neue Cyclopeptide der Formel I Cyclo-(Arg-B-Asp-D-E) I, worin B, D und E die in Anspruch 1 angegebene Bedeutung besitzen, sowie deren Salze. Diese Verbindungen wirken als Integrin-Inhibitoren und können insbesondere zur Prophylaxe und Behandlung von Erkrankungen des Kreislaufs und in der Tumortherapie verwendet werden.
摘要:
The invention relates to a novel purified recombinant α V β 3 adhesion receptor which shows an unimpaired ligand binding activity, and a process for preparing said soluble non-membrane bound receptor in excellent yields by recombinant techniques using a baculovirus-insect cell expression system. The so-synthesized soluble receptor may be used very easily as screening tool for new therapeutic compounds which may inhibit the natural α V β 3 adhesion receptor. Such therapeutic compounds which can be discovered very easily, fast and without health risk by means of the souluble receptors according to the invention may be, for example, RGD peptides or non-peptidic compounds mimicking the natural ligand epitopes. The invention relates, furthermore, to a corresponding process for preparing recombinant full-length α V β 3 adhesion receptor in excellent yields, additionally using detergents to solve the membrane bound receptor from the surface of the host cell.
