title: Design and synthesis of a highly selective EP4-receptor agonist. Part 2: 5-thia and 9beta-haloPG derivatives with improved stability.
abstract: Further chemical modification to identify more chemically stabilized EP4-receptor selective agonists was continued. As a result, a further two EP4-receptor selective agonists 5-thiaPGE(1) 2a, 10 and 9beta-chloroPGF(2) analogue 11 were discovered.
