Conjugates of an immune response modifier, a linker, and an antigen are disclosed. The linker is represented by formula (I): wherein A is CH or N, p is in a range from 1 to 50, R″ is a bond or -alkylene-O—, R′ is alkylene that is optionally interrupted or terminated with one or more amide or ether groups, and E is an amine- or thiol-reactive group. Pharmaceutical compositions containing the compound or the conjugate, methods of making a conjugate, and methods of use of the compounds or conjugates as immunomodulators for inducing cytokine biosynthesis in an animal and for vaccinating an animal are also disclosed. An antigen modified by the linker is also disclosed.
本文揭示了一种免疫应答调节剂、连接剂和抗原的共轭体。连接剂由式(I)表示:其中A为CH或N,p在1到50的范围内,R″为键或-烷基-O-,R′为烷基,可选地中断或终止于一个或多个酰胺或醚基团,E为胺基或硫醇反应基团。还揭示了含有该化合物或共轭体的制药组合物,制备共轭体的方法,以及将化合物或共轭体用作免疫调节剂在动物体内诱导细胞因子生物合成和预防动物的方法。还揭示了由连接剂修饰的抗原。
