Homogeneous suspension
CMC-NA
≥5mg/ml Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 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 Siponimod (BAF312) is a potent and selective S1P receptor agonist, with EC50 of 0.39 nM and 0.98 nM for S1P1 and S1P5receptors, and exhibits >1000-fold selectivity over S1P2, S1P3 and S1P4 receptors.[1] This compound (1 h at 1 μM) promotes prominent internalization of S1P1 receptors by 91%.[2]
in vivo Siponimod (BAF312) effectively suppresses encephalomyelitis (EAE) in rats by internalizing S1P1 receptors, rendering them insensitive to the egress signal from lymph nodes. [1] It significantly reduces clinical scores when dosed prophylactically or therapeutically in mice at 0.3 mg/kg. [3]

キナーゼアッセイ 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.
細胞アッセイ 細胞株 CHO
濃度 ~1 μM
反応時間 1 h
実験の流れ Agonist-mediated internalization of S1P1 receptors in CHO cells analysed by flow cytometry Myc-tag hS1P1 cells are incubated for 1 h with Siponimod (BAF312) 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.
