  Development of a highly selective EP2-receptor agonist. Part 1: identification of 16-hydroxy-17,17-trimethylene PGE2 derivatives

  摘要：

  Design and synthesis of an EP2-receptor selective agonist began with the chemical modification of alpha- and omega-chains of butaprost 1a, which exhibits an affinity for the IP-receptor. Two series of prostaglandin (PG) analogues with a 16-hydroxy-17,17-trimethylene moiety as an omega-chain were identified. Among those tested, 4a,b,e,f,h and 6a,b,e,f,h were found to be highly selective EP2-receptor agonists. Structure activity relationships are discussed. (C) 2002 Elsevier Science Ltd.
