描述 | APD334 is a newly designed, highly specific antagonist targeting S1P1 receptors. In CHO cells expressing HA-tagged S1P1 receptors, APD334 demonstrates an IC50 value of 1.88 nM. While showing some degree of activation at human S1P4 and S1P5 receptors, this activation is notably weaker compared to S1P1, both in terms of potency and efficacy. Notably, APD334 does not exhibit any agonistic or antagonistic effects on human S1P2 and S1P3 receptors. Pharmacokinetic studies across various preclinical species demonstrate favorable central exposure and a promising pharmacokinetic profile. S1P1 receptor activity is maintained in mice (EC50=0.44 nM), rats (EC50=0.32 nM), dogs (EC50=0.34 nM), and monkeys (EC50=0.32 nM) [1]. |
