Abstract: Recently, our research group reported the identification of BMS-986104 (2) as a differentiated S1P receptor modulator. In comparison to fingolimod (1), a full agonist of S1P currently marketed for the treatment of relapse remitting multiple sclerosis (RRMS), 2 offers several potential advantages having demonstrated improved safety multiples in preclinical evaluations against undesired pulmonary and cardiovascular effects. In clinical trials, 2 was found to exhibit a pharmacokinetic half-life ( T) longer than that of 1, as well as a reduced formation of the phosphate metabolite that is required for activity against S1P. Herein, we describe our efforts to discover highly potent, partial agonists of S1P with a shorter T and increased in vivo phosphate metabolite formation. These efforts culminated in the discovery of BMS-986166 (14a), which was advanced to human clinical evaluation. The pharmacokinetic/pharmacodynamic (PK/PD) relationship as well as pulmonary and cardiovascular safety assessments are discussed. Furthermore, efficacy of 14a in multiple preclinical models of autoimmune diseases are presented.
