Abstract

The sphingosine-1-phosphate-1 receptor (S1P1) and its endogenous ligand sphingosine-1-phosphate (S1P) cooperatively regulate lymphocyte trafficking from the lymphatic system. Herein, we disclose 4-methoxy-N-[2-(trifluoromethyl)biphenyl-4-ylcarbamoyl]nicotinamide (8), an uncommon example of a synthetic S1P1 agonist lacking a polar headgroup, which is shown to effect dramatic reduction of circulating lymphocytes (POC = -78%) in rat 24 h after a single oral dose (1 mg/kg). The excellent potency that 8 exhibits toward S1P1 (EC50 = 0.035 μM, 96% efficacy) and the >100-fold selectivity that it displays against receptor subtypes S1P2-5 suggest that it may serve as a valuable tool to understand the clinical relevance of selective S1P1 agonism.
