Amiselimod hydrochloride is a novel sphingosine 1-phosphate receptor-1 (S1P1) modulator, designed to reduce the bradycardia effects associated with fingolimod and other S1P receptor modulators. target: S1P1 In vivo: After oral administration of amiselimod or fingolimod at 1 mg/kg, the concentration of amiselimod-P in rat heart tissue was relatively lower than that of fingolimod-P, potentially contributing to the minimal cardiac effects of amiselimod. Amiselimod-P showed potent selectivity for S1P1 , high selectivity for S1P5 , minimal agonist activity for S1P4 , no distinct agonist activity for S1P2 or S1P3 , and approximately 5-fold weaker GIRK activation than fingolimod-P. [1] Amiselimod 0·2 mg and 0·4 mg significantly reduced the total number of gadolinium-enhanced T1-weighted lesions. [2]
