Biological Activity

Description BAF312 (Siponimod) is a next-generation S1P receptor agonist, 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.
Targets
S1P1 receptor [1] S1P5 receptor [1]
0.39 nM(EC50) 0.98 nM(EC50)
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. [1]BAF312 (1 h at 1 μM) promotes prominent internalization of S1P1 receptors by 91%.[2]
In vivo BAF312 effectively suppresses encephalomyelitis (EAE) in rats by internalizing S1P1 receptors, rendering them insensitive to the egress signal from lymph nodes. [1] BAF312 significantly reduces clinical scores when dosed prophylactically or therapeutically in mice at 0.3 mg/kg. [3]

Protocol (from reference)

Kinase Assay:[1]
  • GTPγ[35S] binding assay

    The cells are homogenized and centrifuged at 26900 × g for 30 min at 4°C. Membranes are re-suspended in 20 mM HEPES (pH 7.4), 100 mM NaCl, 10 mM MgCl2, 1 mM EDTA and 0.1% fat-free BSA at 2–3 mg protein/mL. GTPγ[35S] binding assay is performed with the membranes (75 mg protein /mL in 50 mM HEPES, 100 mM NaCl, 10 mM MgCl2, 20 μg/mL saponin and 0.1% fat-free BSA (pH 7.4), 5 mg/mL with wheat-germ agglutinin-coated scintillation proximity assay-bead, and 10 μM GDP for 10–15 min. The GTPγ[35S]-binding reaction is started by the addition of 200 pM GTPγ[35S]. After 120 min at room temperature, the plates are centrifuged for 10 min at 300 × g and counted.

  • Cell lines

    CHO

  • Concentrations

    ~1 μM

  • Incubation Time

    1 h

  • Method

    Agonist-mediated internalization of S1P1 receptors in CHO cells analysed by flow cytometry Myc-tag hS1P1 cells are incubated for 1 h with agonist at 37°C in standard culture medium followed by a PBS wash. An aliquot is kept on ice for 3 h, while another aliquot is left for 3 (or 12) h in culture medium (no agonist) at 37°C. The cells are then incubated either with 4 μg/mL monoclonal mouse anti C-myc IgG1 antibody or with isotype control mouse IgG1 for 60 min at 4°C, followed by an incubation with 1 μg/mL of Alexa488-labelled goat anti-mouse secondary conjugates. The cells are subjected to flow cytometry measurements using 10000 viable cells per sample.
Animal Study:[1]
  • Animal Models

    encephalomyelitis (EAE) model rat

  • Dosages

    0.03, 0.3 and 3 mg/kg

  • Administration
