CYM50358 is a potent and selective S1PR4 antagonist, with an IC50 of 25 nM. CYM50358 can be used for the research of influenza infection[1][2].
CYM50358 shows less potent inhibition of S1PR1 (IC50=6.4 μM)[1].CYM50358 (10 μM) has no effect on the collagen-induced HSP27 phosphorylation, markedly reverses the suppressive effect of S1P on the collagen-induced phosphorylation of HSP27[2].

Suppressive Effect of CYM50358 S1P4 Antagonist on Mast Cell Degranulation and Allergic Asthma in Mice
Biomol Ther (Seoul) 2021 Sep 1;29(5):492-497.PMID:33500376DOI:10.4062/biomolther.2020.206.
Levels of sphingosine 1-phosphate (S1P), an intercellular signaling molecule, reportedly increase in the bronchoalveolar lavage fluids of patients with asthma. Although the type 4 S1P receptor, S1P4 has been detected in mast cells, its functions have been poorly investigated in an allergic asthma model in vivo. S1P4 functions were evaluated following treatment of CYM50358, a selective antagonist of S1P4, in an ovalbumin-induced allergic asthma model, and antigen-induced degranulation of mast cells. CYM50358 inhibited antigen-induced degranulation in RBL-2H3 mast cells. Eosinophil accumulation and an increase of Th2 cytokine levels were measured in the bronchoalveolar lavage fluid and via the inflammation of the lungs in ovalbumin-induced allergic asthma mice. CYM50358 administration before ovalbumin sensitization and before the antigen challenge strongly inhibited the increase of eosinophils and lymphocytes in the bronchoalveolar lavage fluid. CYM50358 administration inhibited the increase of IL-4 cytokines and serum IgE levels. Histological studies revealed that CYM50358 reduced inflammatory scores and PAS (periodic acid-Schiff)-stained cells in the lungs. The pro-allergic functions of S1P4 were elucidated using in vitro mast cells and in vivo ovalbumin-induced allergic asthma model experiments. These results suggest that S1P4 antagonist CYM50358 may have therapeutic potential in the treatment of allergic asthma.
Sphingosine 1-phosphate (S1P) suppresses the collagen-induced activation of human platelets via S1P4 receptor
Thromb Res 2017 Aug;156:91-100.PMID:28609704DOI:10.1016/j.thromres.2017.06.001.
Sphingosine 1-phosphate (S1P) is as an extracellular factor that acts as a potent lipid mediator by binding to specific receptors, S1P receptors (S1PRs). However, the precise role of S1P in human platelets that express S1PRs has not yet been fully clarified. We previously reported that heat shock protein 27 (HSP27) is released from human platelets accompanied by its phosphorylation stimulated by collagen. In the present study, we investigated the effect of S1P on the collagen-induced platelet activation. S1P pretreatment markedly attenuated the collagen-induced aggregation. Co-stimulation with S1P and collagen suppressed collagen-induced platelet activation, but the effect was weaker than that of S1P-pretreatment. The collagen-stimulated secretion of platelet-derived growth factor (PDGF)-AB and the soluble CD40 ligand (sCD40L) release were significantly reduced by S1P. In addition, S1P suppressed the collagen-induced release of HSP27 as well as the phosphorylation of HSP27. S1P significantly suppressed the collagen-induced phosphorylation of p38 mitogen-activated protein kinase. S1P increased the levels of GTP-bound Gαi and GTP-bound Gα13 coupled to S1PPR1 and/or S1PR4. CYM50260, a selective S1PR4 agonist, but not SEW2871, a selective S1PR1 agonist, suppressed the collagen-stimulated platelet aggregation, PDGF-AB secretion and sCD40L release. In addition, CYM50260 reduced the release of phosphorylated-HSP27 by collagen as well as the phosphorylation of HSP27. The selective S1PR4 antagonist CYM50358, which failed to affect collagen-induced HSP27 phosphorylation, reversed the S1P-induced attenuation of HSP27 phosphorylation by collagen. These results strongly suggest that S1P inhibits the collagen-induced human platelet activation through S1PR4 but not S1PR1.
TGFβ1 evokes myoblast apoptotic response via a novel signaling pathway involving S1P4 transactivation upstream of Rho-kinase-2 activation
FASEB J 2013 Nov;27(11):4532-46.PMID:23913862DOI:10.1096/fj.13-228528.
In view of its multiple detrimental effects, transforming growth factor β1 (TGFβ1) is recognized as critical negative regulator of skeletal muscle repair. Apoptosis of skeletal muscle precursor cells driven by TGFβ1 contributes to the negative role exerted by the cytokine in tissue repair, although the underlying molecular mechanisms are still elusive. Herein we report the identification of a new signaling pathway, relying on Rho kinase-2 stimulation, subsequent to SMAD-dependent S1P4 up-regulation and transactivation via sphingosine kinase (SK)-2, that accounts for TGFβ1-induced apoptosis in cultured myoblasts. S1P4-specific gene silencing reduced by almost 50% activation of caspase-3 and poly-ADP ribosyl transferase cleavage elicited by TGFβ1. Moreover, the selective S1P4 antagonist CYM50358 also reduced the TGFβ1 proapoptotic effects. By employing pharmacological and molecular biological approaches, the involvement of SK2 and ROCK2 in the transmission of the TGFβ1 apoptotic action was also demonstrated. These results reinforce the notion that the SK/S1P axis plays a fundamental role in TGFβ1 mode of action in skeletal muscle cells and, by disclosing a novel mechanism by which TGFβ1 exerts its harmful action, pinpoint new molecular targets that in principle could be beneficial in the treatment of several skeletal muscle disorders or aging-dependent muscle atrophy.
