Synthesis and structure-activity relationships of a new class of selective EP3 receptor agonist, 13,14-didehydro-16-phenoxy analogues of prostaglandin E1

Article abstract of DOI:10.1016/S0968-0896(99)00288-6

A series of 13,14-didehydro-16-phenoxy analogues of prostaglandin E₁ was synthesized and their agonistic activity on EP receptor subtypes was evaluated. 13,14-Didehydro-16-phenoxy-1-decarboxy analogues, 7e and 7f, display highly selective activity on the EP₃ receptor subtype, thus, their utility as a selective anti-ulcer agent can be expected.
