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) は、次世代S1P受容体モジュレーターであり、S1P1およびS1P5受容体に選択的で、EC50は0.39 nMおよび0.98 nMであり、S1P2、S1P3、S1P4受容体に対して1000倍以上の選択性を示します。フェーズ3。
in vitro Siponimod (BAF312) is a potent and selective S1P receptor agonist, exhibiting EC50 values of 0.39 nM and 0.98 nM for S1P1 and S1P5 receptors, with >1000-fold selectivity over S1P2, S1P3, and S1P4 receptors. This compound (1 h at 1 μM) promotes prominent internalization of S1P1 receptors by 91%.
in vivo Siponimod (BAF312) effectively suppresses encephalomyelitis (EAE) in rats by internalizing S1P1 receptors, rendering them insensitive to the egress signal from lymph nodes. It significantly reduces clinical scores when dosed prophylactically or therapeutically in mice at 0.3 mg/kg.

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.
