产品描述:
Prostaglandin E2 (PGE2) activates four E prostanoid (EP) receptors, EP1-4. EP4 is a Gs protein-coupled receptor that, by elevating the second messenger cAMP, plays important roles in bone formation and resorption, cancer, and atherosclerosis.{16772,16773,16619} L-902,688 is a highly potent agonist of the human PGE2 receptor, EP4. It demonstrates a Ki value of 0.38 nM and an EC50 value of 0.6 nM and is >4,000-fold selective for EP4 over other EP and prostanoid receptors.{17923} L-902,688 induces thermal hyperalgesia when injected into guinea pig forepaw and increases vasodilation of human pulmonary vein.{18105,16074}
