The present invention relates to novel Mannose-binding lectin (MBL)-associated serine protease (MASP) inhibitory compounds, as well as analogues and derivatives thereof, to processes for the preparation thereof, to the use thereof alone or in combinations for treatment and/or prevention of diseases and to the use thereof for production of medicaments for treatment and/or prevention of diseases, especially for treatment and/or prevention of renal and cardiovascular disorders and of ischemia reperfusion injuries.
Described is a pretargeting method, and related kits, for targeted medical imaging and/or therapeutics, wherein use is made of abiotic reactive chemical groups that exhibit bio-orthogonal reactivity towards each other. The invention involves the use of [4+2] inverse electron demand (retro) Diels-Alder chemistry in providing the coupling between a Pre-targeting Probe and an Effector Probe. To this end one of these probes comprises an electron-deficient tetrazine or other suitable diene, and the other a cyclooctene or cyclooctyne.
Described is a method, and a combination of agents for used therein, by which an agent administered to a subject can be rapidly cleared from circulation. This is achieved by providing an Administration Agent (e.g. a probe for pretargeting) with a reactive group and providing a Clearing Agent with another reactive group, said reactive groups forming a bio-orthogonally reactive pair. Preferably, the reactive pair comprises a cyclooctene or cyclooctyn as one reactant, and a diene as the other reactant. The method and combination can be used for the removal of any bindable molecule from circulation, such as an excess of a pre-targeting probe in the course of a pre-targeting method, a targeting or imaging agent delivered, or the removal of any biomolecule already present in circulation.
