Discovery of a potent and selective agonist of the prostaglandin EP4 receptor
摘要:
Analogues of PGE(2) wherein the hydroxycyclopentanone ring has been replaced by a lactam have been prepared and evaluated as ligands for the EP4 receptor. An optimized compound (19a) shows high potency and agonist efficacy at the EP4 receptor and is highly selective over the other seven known prostaglandin receptors. (C) 2003 Elsevier Science Ltd.

subtype of prostaglandin E2 receptors, their use or a formulation thereof in the treatment of glaucoma and other conditions that are related to elevated intraocular pressure in the eye of a patient. This invention also relates to the use of such compounds to provide a neuroprotective effect to the eye of mammalian species, particularly humans.
