Provided herein is dendrimer-targeting agent conjugate comprising: (a) a dendrimer comprising i) a core unit (C); and ii) building units (BU), wherein the dendrimer has from two to six generations of building units; and wherein the core unit is covalently attached to at least two building units; and the dendrimer further comprising: b) a targeting agent which is covalently linked to the dendrimer by a spacer group; c) one or more first terminal groups attached to an outermost building unit of the dendrimer, wherein the first terminal group comprises a complexation group for complexing a radionuclide; and d) one or more second terminal groups attached to an outermost building unit of the dendrimer, wherein the second terminal group comprises a pharmacokinetic-modifying moiety, or a salt thereof. Also provided are compositions comprising the dendrimer-targeting agent conjugates, and methods of using the dendrimer-targeting agent conjugates and compositions comprising them in therapeutic and imaging applications.
本文提供了一种树状分子靶向药物复合物,包括:(a)一种树状分子,包括i)一个核心单元(C);和ii)构建单元(BU),其中该树状分子具有从两个到六个代的构建单元;核心单元与至少两个构建单元共价连接;该树状分子还包括:(b)一种靶向药物,通过一个空间基团与树状分子共价连接;(c)一个或多个第一端基团,连接在树状分子的最外层构建单元上,其中第一端基团包括一个络合基团,用于络合放射性核素;(d)一个或多个第二端基团,连接在树状分子的最外层构建单元上,其中第二端基团包括一个药代动力学修饰基团或其盐。还提供了包括该树状分子靶向药物复合物的组合物,以及使用该树状分子靶向药物复合物和组合物在治疗和成像应用中的方法。
