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.
描述了一种方法,以及其中使用的一组药剂组合,通过该方法,可以迅速清除给予受试者的药剂在循环中的存在。这是通过提供具有反应基团的给药剂(例如,用于预先靶向的探针)和提供具有另一种反应基团的清除剂来实现的,所述反应基团形成
生物正交反应对。最好,反应对包括环
辛烯或
环辛炔作为一种反应物,二烯作为另一种反应物。该方法和组合可用于从循环中去除任何可结合分子,例如,在预先靶向方法中清除探针的过量,传递的靶向或成像剂,或已存在于循环中的任何
生物分子的清除。
