Abstract: Described herein are cyclic peptides targeting fibroblast activation protein (FAP), and their incorporation into compounds for radioligand imaging and therapies, as well as methods and/or uses of such compounds for the imaging, treatment and/or prevention of FAP-implicated diseases and disorders.

Abstract: The present invention provides methods and compositions useful in the screening for agents that modulate activity of a deubiquitinating enzyme. In one embodiment, the invention relates to methods for measuring a deubiquitination activity comprising combining a deubiquitinating enzyme (DUB) with a substrate comprising a ubiquitin moiety and a fluorescently labeled compound under conditions allowing for deubiquitinating activity and measuring an altered fluorescence polarization and/or fluorescence lifetime of the released fluorescently labeled compound The invention also relates to a substrate library comprising peptides of the formula (Z)a(X)mK(X)n(Z)b useful e.g. for the determination of the substrate specificity of a deubiquitinating enzyme.

Abstract: The present invention provides a method for preventing or treating acute or chronic graft rejection in a recipient of cell, tissue or organ allo- or xenotransplant, inflammatory or autoimmune diseases or malignant proliferative disease, comprising the use of an inhibitor of Vav. Further provided are Vav inhibitors, uses, pharmaceutical compositions and therapeutic combinations comprising Vav inhibitors, and screening methods therefore.
