Alteration in lymphocyte trafficking and prevention of graft rejection in rodents observed on exposure to FTY720 (1) or its corresponding phosphate ester 2 can be induced by the systemic administration of potent sphingosine-1-phosphate receptor agonists exemplified by 19. The similar S1P receptor profiles of 2 and 19 coupled with their comparable potency in vivo supports a connection between S1P receptor agonism and immunosuppressive efficacy.
