| Hazard Information | Back Directory | [Description]
Prostaglandin E2 (PGE2) exerts its effects through four separate G coupled-protein receptors (EP1-4). L-161,982 is a potent and selective EP4 receptor antagonist. It demonstrates selective binding to human EP4 receptors with a Ki value of 0.024 μM compared to other receptors of the prostanoid family, EP1, EP2, EP3, DP, FP, and IP, with Ki values of 17, 23, 1.9, 5.1, 5.6, and 6.7 μM, respectively. L-161,982 at 10 mg/kg/day suppresses PGE2-stimulated bone formation in young rats and at 100 nM reverses the anti-inflammatory action of PGE2 in LPS-activated human macrophages. At 10 μM L-161982 blocks PGE2-induced cell proliferation in HCA-7 colon cancer cells. | [Uses]
L-161,982 is an EP4 receptor antagonist, which blocks prostaglandin E2-induced signal transduction and cell proliferation in HCA-7 colon cancer cells. | [Definition]
ChEBI: N-[2-[4-[[3-butyl-5-oxo-1-[2-(trifluoromethyl)phenyl]-1,2,4-triazol-4-yl]methyl]phenyl]phenyl]sulfonyl-3-methyl-2-thiophenecarboxamide is a member of biphenyls. | [Biological Activity]
EP 4 receptor antagonist that is selective over all other members of the prostanoid receptor family (K i values are 0.024, 0.71, 1.90, 5.10, 5.63, 6.74, 19 and 23 μ M for human EP 4 , TP, EP 3 , DP, FP, IP, EP 1 and EP 2 receptors respectively). Suppresses PGE 2 -induced bone formation in rats and prevents the nociceptive response induced by misoprostol in formalin-injected mice. | [Biochem/physiol Actions]
