target validation

FKBP12 PROTAC dTAG-13是一种PROTAC和选择性降解剂，通过接合FKBP12 F36V和CRBN从而降解 FKBP12 F36V，可用于药物发现过程中的靶标验证。

PSB-KD477 is an Agonist of the Cannabinoid-Activated Orphan G-Protein-Coupled Receptor GPR18. PSB-KD477 displayed significantly higher potency and efficacy than THC, determined in a GPR18-dependent β-arrestin recruitment assay, and were found to be selective versus the CB-sensitive receptors CB1, CB2, and GPR55. Structure-activity relationships were steep, and indole substitution was crucial for biological activity. These first selective agonists, which are structurally distinct from the lipidic agonist(s), will allow target validation studies and may eventually contribute to the deorphanization of GPR18.
