A series of 3-arylpropionic acids were synthesized as S1P(1) receptor agonists. Structure-activity relationship studies on the pendant phenyl ring revealed several structural features offering selectivity of S1P(1) binding against S1P(2-5). These highly selective SIP, agonists induced peripheral blood lymphocyte lowering in mice and one of them was found to be efficacious in a rat skin transplantation model, supporting that S1P(1) agonism is primarily responsible for the immunosuppressive efficacy observed in preclinical animal models.
