Siponimod (BAF-312) is an orally active, blood-brain barrier penetrant dual agonist of S1P1/S1P5, with EC₅₀ values of 0.39 nM and 0.98 nM, respectively. Siponimod induces S1P1 internalization, activates GIRK channels, inhibits lymphocyte egress, reduces peripheral lymphocyte counts, triggers transient bradycardia, prevents synaptic neurodegeneration, promotes remyelination, alleviates demyelination, and prevents the loss of GABAergic interneurons. Siponimod can be used in research related to multiple sclerosis.

In Vitro

Siponimod (10-1000 nM; 4-13 h) induces significant and persistent internalization of human S1P₁ receptors in CHO cells. Obvious internalization is detectable even at concentrations as low as 10 nM, and the receptors remain localized intracellularly after drug washout^[1].
Siponimod regulates microglial function by reducing IL6 secretion in cultured microglia^[4].
Siponimod improves oligodendrocyte degeneration by alleviating demyelination in organotypic brain slice cultures^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Siponimod (0.03-3 mg/kg; p.o.; daily; day 11 to day 34 post-immunization) dose-dependently suppresses established chronic experimental autoimmune encephalomyelitis in female DA rats, with significant efficacy observed at doses of 0.3 mg/kg and 3 mg/kg^[1].
Siponimod (0.14-1 mg/kg; p.o.; single dose) causes a rapid, dose-dependent reduction in peripheral lymphocyte counts in Lewis rats, with an ED₅₀ of 0.14 mg/kg at 6 hours post-dose, and counts return to normal within 48 hours^[2].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
