alkynyl), preferably a terminal alkynyl. The bifunctional linker is used in a cycloaddition to tether two entities, for example a protein or antibody, and an active agent, to form a bisconjugate. The bifunctional linker also be used to form a conjugate, followed by cycloaddition in the presence of a comonomer composition to form a bisconjugate including a protein or antibody linked to an adhesive polymer network. Catalysis can be provided by a copper-containing paint on a surface to adhere the bisconjugate to the surface. Methods of synthesis and use of the bisconjugates imaging, diagnostic, and therapeutic applications are also described.
公式1的双官能团连接剂,其中在公式I中,至少一个R1至R4为—COOR5,且R5为—C0-C10烷基(C2-C10炔基)或—C0-C10烷基-C2-C10烯基(C2-C10炔基),优选为末端炔基。该双官能团连接剂用于环加成反应,将两个实体(例如蛋白质或
抗体)和一个活性剂连接起来,形成一个双共轭体。该双官能团连接剂还可用于形成共轭体,随后在共单体组成物的存在下进行环加成反应,形成包括连接到粘附性聚合物网络的蛋白质或
抗体的双共轭体。催化剂可以由涂在表面上的含
铜涂料提供,以将双共轭体粘附到表面上。还描述了制备和使用双共轭体的方法,包括成像、诊断和治疗应用。
