Based on the intracellular CCR9 antagonist vercirnon, we developed the first small-molecule-based fluorescent ligand targeting the intracellular allosteric binding site (IABS) of a GPCR. This tool enabled binding studies via NanoBRET, fluorescence microscopy, and the discovery of a new intracellular CCR9 antagonist with improved affinity. To induce CCR9 degradation, we developed the first PROTAC targeting
基于细胞内 CCR9 拮抗剂 vercirnon,我们开发了第一个基于小分子的荧光配体,靶向 GPCR 的细胞内变构结合位点 (IABS)。该工具能够通过 NanoBRET、荧光显微镜进行结合研究,并发现具有更高亲和力的新型细胞内 CCR9 拮抗剂。为了诱导 CCR9 降解,我们开发了第一个针对 GPCR 的 IABS 的 PROTAC。
