YE-120 is a GPR35 agonist (EC50 = 32 nM in DMR assays). YE-120 also displays partial agonist activity in a β-arrestin translocation assay (EC50 = 10.2 μM). GPR35 is a Class A, rhodopsin-like G protein-coupled receptor which is predominantly expressed in immune and gastrointestinal tissue, with notable expression in the ileum (rat and human GPR35), the spleen (rat and murine GPR35) and the pancreas (human GPR35).
