Ex26 (S1P1-IN-Ex26) 是一种强效和选择性的 sphingosine 1-phosphate receptor 1 (S1P1) 拮抗剂 (IC50=0.93 nM)，对 S1P1 的选择性大于其他 Sphingosine 1-phosphate receptor 约 3,000 倍。Ex26 可用于实验性自身免疫性脑脊髓炎的研究。

Ex26 (S1P1-IN-Ex26) is a potent and selective sphingosine 1-phosphate receptor 1 (S1P1) antagonist (IC50=0.93 nM). Ex26 shows >3,000-fold selectivity for S1P1 over other Sphingosine 1-phosphate receptors. Ex26 can be used in experimental autoimmune encephalomyelitis reseach.

Ex26 (0-10 μM; 1 h) treatment shows excellent selectivity for S1P1 over other Sphingosine 1-phosphate receptors.Cell Viability Assay Cell Line:U2OS cells, and Chinese hamster ovary cells Concentration:0-10 μM Incubation Time:1 hour Result:Confirmed a potent and selective antagonist of S1P1 (IC50=0.93 nM).

Ex26 (i.p.; 3 mg/kg; once daily; 3 d) treatment disrupts S1P1 signaling inhibiting the lymphocyte and thymocyte egress.Ex26 (i.p.; 30 mg/kg; once daily; 15 d) treatment alleviates experimental autoimmune encephalomyelitis by S1P1 antagonism.Animal Model:Eight-week-old male C57Bl/6J mice Dosage:3 mg/kg Administration:Intraperitoneal injection; 3 mg/kg; once daily; 3 days Result:Induced lymphocyte sequestration at low doses, possessing an ED50 of 0.06 mg/kg after 2 hours treatment. Led to significant retention of T and B cells within the lymph nodes and significant decreases in T and B cells within the spleen.Animal Model:Eight-week-old male C57Bl/6J mice induced with experimental autoimmune encephalomyelitis Dosage:30 mg/kg Administration:Intraperitoneal injection; 30 mg/kg; once daily; 15 days Result:Inhibited both lymphocyte infiltration and destruction of the white matter in the spinal cord of mice euthanized at the end of the experiment.
