Disclosed is an advancement in provoked chemical cleavage. Thereby the invention provides the use of a diene as a chemically cleavable group attached to a Construct, and the use of a dienophile to provoke the release of the Construct by allowing the diene to react with a dienophile capable of undergoing an inverse electron demand Diels Alder reaction with the diene. The invention includes a kit for releasing a Construct C A bound to a Trigger T R , the kit comprising a tetrazine and a dienophile, wherein the Trigger is the tetrazine. The invention also includes the use of the formation of a pyridazine by reacting a tetrazine comprising a Construct C A bound thereto and a dienophile, as a chemical tool for the release, in a chemical, biological or physiological environment, of said Construct. |
