| Targets&IC50 | S1P1:0.93 nM |
| In vitro | In U2OS cells and Chinese hamster ovary cells, Ex26 (0-10 μM; 1 hour) was confirmed as a potent and selective antagonist of S1P1 (IC50=0.93 nM)[1]. |
| In vivo | In eight-week-old male C57Bl/6J mice, S1P1-IN-Ex26 (3 mg/kg; intraperitoneal injection; once daily; 3 days) induced lymphocyte sequestration at low doses, with an ED50 of 0.06 mg/kg after 2 hours of treatment. This led to significant retention of T and B cells within the lymph nodes and significant decreases in T and B cells within the spleen[1]. |
