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 Research: [1]
  • 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 Research:[1]
  • Animal Models: encephalomyelitis (EAE) model rat
  • Dosages: 0.03, 0.3 and 3 mg/kg
  • Administration: oral gavage

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
