Disclosed are biotinidase resistant biotinyl-conjugates, and uses thereof. The conjugates comprise a biotinyl moiety coupled to a therapeutic or diagnostic moiety by a triazole group. The conjugates have applications as diagnostic or therapeutic agents, in methods of diagnosis or treatment of a subject, for example as MRI contrast agents in MRI imaging of a subject. In particular, biotinyl-chelate complexes find utility in two and three step pretargeting strategies and have high affinity for avidin, streptavidin and related proteins. Also disclosed are biotinylating agents and kits, and the use of compounds for biotinylation, including for the synthesis of biotinyl-chelate complexes and biotinyl-conjugates.
本发明涉及耐生物素酶的生物素基共轭物及其用途。该共轭物包括通过三唑基团将生物素基团与治疗或诊断基团耦合而成。该共轭物可用于诊断或治疗剂,用于诊断或治疗主体的方法,例如用于主体的MRI成像中作为MRI对比剂。特别是,生物素基螯合物复合物在两步或三步预靶向策略中具有实用性,并具有高亲和力,可与亲合素、链霉亲合素和相关蛋白结合。本发明还涉及生物素化试剂和试剂盒,以及用于生物素化的化合物的使用,包括用于合成生物素基螯合物复合物和生物素基共轭物的化合物。
