S1PR4 Agonist

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.

Ponesimod (ACT-128800) is a potent, selective and orally active agonist of S1P₁, with an IC₅₀ of 6 nM in a radioligand binding assay. Ponesimod activates S1P₁-mediated signal transduction with high potency (EC₅₀=5.7 nM). Ponesimod can protect against lymphocyte-mediated tissue inflammation.

CYM-5478 is a potent and highly selective S1P₂ agonist with an EC₅₀ of 119 nM in a TGFα-shedding assay. CYM-5478 protects neural-derived cell lines against Cisplatin toxicity.

Cenerimod (ACT-334441) is a potent, selective and orally active S1P1 receptor modulator, with an EC₅₀ of 1 nM. Cenerimod shows more than 36 fold selctivity for hS1P1 over hS1P2, hS1P3, hS1P4, and hS1P5 receptor subtypes (EC₅₀s=>10000, 228, 2134, and 36 nM, respectively). Cenerimod can attenuate murine experimental autoimmune encephalomyelitis (EAE) and murine sclerodermatous.

VPC 23153 is a S1P₄ receptor agonist and vasoconstrictor. VPC 23153 activates the S1P₄ receptor, thereby triggering vasoconstriction. VPC 23153 induces pulmonary artery contraction. VPC 23153 can be used in studies related to pulmonary arterial hypertension.

CYM50179 (compound 22n) is a potent and selective S1P4-R (Sphingosine-1-phosphate4 receptor) agonist with an EC₅₀ of 46 nM.

Siponimod (BAF-312) hemifumarate 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 hemifumarate 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 hemifumarate can be used in research related to multiple sclerosis.
