S1P1 Agonist 1 (1.3mg/kg) attenuates EAE disease. EAE is the animal model of multiple sclerosis which is extensively used for investigating clinical studies for multiple sclerosis drugs. S1P1 Agonist 1 treatment reduces peripheral total blood lymphocyte and T lymphocyte counts significantly. The reduction in total lymphocytes and T cells are 48% and 41% in AKP-11 treated animals, respectively. The reduction in the CD4+ and CD8+ T cell populations are 41% and 40% in S1P1 Agonist 1 treated animals, respectively. S1P1 Agonist 1 treatment reduces CNS infiltration of T cells and Cytokines and enhances neuroprotection. S1P1 Agonist 1 treatment has little effect on the heart rate of animals. The decrease in blood pressure is also smaller with S1P1 Agonist 1 treatment as compared animals treated with FTY720[1].
