Questions And Answer

• Description

  BAF312 (Siponimod) is a next-generation S1P receptor modulator, selective for S1P1 and S1P5 receptors with EC50 of 0.39 nM and 0.98 nM, exhibits >1000-fold selectivity over S1P2, S1P3 and S1P4 receptors. Phase 3.;

• In vitro

  BAF312 (Siponimod) is a potent and selective S1P receptor agonist, with EC50 of 0.39 nM and 0.98 nM for S1P1 and S1P5receptors, exhibits >1000-fold selectivity over S1P2, S1P3 and S1P4 receptors. BAF312 (1 h at 1 μM) promotes prominent internalization of S1P1 receptors by 91%.;

• In vivo

  BAF312 effectively suppresses encephalomyelitis (EAE) in rats by internalizing S1P1 receptors, rendering them insensitive to the egress signal from lymph nodes. BAF312 significantly reduces clinical scores when dosed prophylactically or therapeutically in mice at 0.3 mg/kg.;
