Abstract: The present invention describes a uPAR-targeting peptide conjugate comprising a fluoro bore, a peptide binding to uPAR and a linker group which are connected by covalent bonds, wherein the uPAR-targeting peptide conjugate may be used as fluorescence probe in real time optical imaging and delineation of cancer tumors or metastases during surgery.

Abstract: There is provided a 177-Lu labelled peptide for site-specific targeting of the Urokinase Plasminogen Activator Receptor (uPAR) thereby enabling treatment of a cancer disease associated with high uPAR expression; e.g. treatment of colorectal cancer by administering to a patient an effective amount of the 177-Lu labelled peptide.

Abstract: There is provided a novel conjugate that binds to the cell surface receptor uPA (uPAR). The conjugate is based on a fluorescence-labeled peptide useful as a diagnostic probe to the surfaces of cells expressing uPAR. The conjugate is capable of carrying a suitable detectable and imageable label that will allow qualitative detection and also quantitation of uPAR levels in vitro and in vivo. This renders the surgical resection of tumors more optimal.

Abstract: The present invention relates to a method of inducing cancer cells into dormancy and treating cancer in a subject. This method involves administering to a subject an effective amount of a compound that disrupts interaction between urokinase plasminogen activator receptor and integrin, thereby including cancer cells into dormancy and treating cancer in the subject. Also disclosed is a method of disrupting interaction between integrin and urokinase plasminogen activator receptor on cancer cells. The present invention also relates to a method of screening for compounds effective in inducing tumor dormancy and treating cancer in a subject.

Abstract: A novel set of inhibitors of the binding interaction between human urokinase plasminogen activator (uPA) and its cell surface receptor (uPAR) has been developed. The inhibitors comprise of peptide fragments, monomeric or in multiple copies attached to a common scaffold, in which the amino acid sequence may include uncommon substituted amino acids to partially comprise of peptoid sequences. The present invention also relates to the use of such peptides in therapy, in particular for the treatment of cancer, having developed a modified non-human mammalian receptor to which the novel inhibitors are antagonistic.

Abstract: A polypeptide presenting an epitope cross-reactive with an epitope of urokinase-type plasminogen activator receptor, and/or having uPA binding activity, is described.

Abstract: Activation of plasminogen to plasmin is inhibited by preventing the binding of a receptor binding form of urokinase-type plasminogen activator to a urokinase-type plasminogen activator receptor in a mammal, thereby preventing the urokinase-type plasminogen activator from converting plasminogen into plasmin. DNA fragments which encode for soluble, active fragments of the urokinase-type plasminogen activator receptor are provided.

Abstract: The invention relates to an antibody which inhibits the binding between u-PA and u-PAR to an extent of at least 90% in an assay as defined in the specification, or an active fragment or immunological equivalent of said antibody. Examples of such antibodies are deposited Jul. 7, 1994 at Deutsche Sammlung von Mikroorganismen und Zellkulturen (DSM) with accession numbers DSM ACC2178 and DSM ACC2179 under the terms and conditions of the Budapest Treaty. The invention furthermore relates to a method for detecting or quantifying u-PAR or a glycosylation variant of u-PAR in a sample by use of an antibody according to the invention.Furthermore, the invention relates to a method for the manufacture of a therapeutic agent for preventing or counteracting localized proteolytic activity using of an antibody of the invention as well as to use of an antibody according to the invention for the preparation of a diagnostic agent which is capable of targeting a diagnostic to a cell that contains a u-PAR on the surface.

Abstract: Activation of plasminogen to plasma is inhibited by preventing the binding of a receptor binding form of urokinase-type plasminogen activator to a urokinase-type plasminogen activator receptor in a mammal, thereby preventing the urokinase-type plasminogen activator from converting plasminogen into plasmin. DNA fragments which encode for soluble, active fragments of the urokinase-type plasminogen activator are provided.
