General description
A non-toxic thiourea derivative that acts as a blocker of Orai1, the pore subunit of Ca2+-release-activated Ca2+ (CRAC) in T cells. Exhibits a strong blocking effect on store-operated Ca2+ entry in HeLa-O+S cells and in Th17 cells. Preferentially reduces Th17 differentiation and ameliorates Th17-mediated autoimmune disease. Blocks the infiltration of T cells into the CNS and reduces the number of IL-17 producing cells. Also shown to reduce the expression of retinoic acid receptor-related orphan receptors a (RORa) and RORgt. Reduces the symptoms and delays the onset of experimental autoimmune encephalomyelitis (EAE) in myelin oligodendrocyte glycoproteins 35-55 (MOG35-55) immunized mice (2 mg/kg, i.p.).
