Based on the intracellular CCR9 antagonist vercirnon, we developed the first small-molecule-based fluorescentligand targeting the intracellularallostericbindingsite (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
