Disclosed is a kit for the administration and activation of a Prodrug. The kit comprises a Masking Moiety linked, directly or indirectly, to a Trigger moiety, which in turn is linked to a Drug, and an Activator for the Trigger moiety. The Trigger moiety comprises a dienophile and the Activator comprises a diene, whereby the dienophile is an eight-membered non-aromatic cyclic alkenylene group, preferably a cyclooctene group, and more preferably a trans-cyclooctene group. The Trigger and the Activator undergo a fast, bio-orthogonal reaction resulting in the release of the Masking Moiety, and activation of the drug.
本发明揭示了一种用于前药管理和激活的套件。该套件包括一个与触发物质直接或间接连接的掩蔽基团,该触发物质又连接到药物,以及触发物质的活化剂。触发物质包括二亚甲基丙烯酰基,活化剂包括二烯,其中二亚甲基丙烯酰基是一种八元非芳香环烯基基团,优选为环辛烯基团,更优选为反式环辛烯基团。触发物质和活化剂经历快速的生物正交反应,导致掩蔽基团的释放和药物的激活。
