    Product Description

    ER-819762 is an antagonist of the prostaglandin E2 (PGE2; Item No. 14010) receptor subtype EP4 (IC50 = 70 nM).1 It is selective for EP4 over EP1, EP2, and EP3 in a cAMP reporter assay at 10 µM. ER-819762 reduces differentiation of mouse helper T cells when used at concentrations ranging from 0.1 to 10 nM and decreases IL-23 secretion by mouse dendritic cells from 0.04 to 5 nM. It also reduces the levels of Marek's disease virus (MDV) in chicken embryonic fibroblasts (CEFs) when used at a concentration of 1 µM.2 Oral administration of ER-819762 (30 and 100 mg/kg) prevents and reverses paw swelling, edema, and inflammation in a mouse model of rheumatoid arthritis induced by glucose-6-phosphate isomerase (GPI).1
