  Synthesis and evaluation of γ-lactam analogs of PGE2 as EP4 and EP2/EP4 agonists

  摘要：

  To identify topically effective EP4 agonists and EP2/EP4 dual agonists with excellent subtype selectivity, further optimization of the 16-phenyl omega-chain moiety of the gamma-lactam 5-thia prostaglandin E analog and the 2-mercaptothiazole-4-carboxylic acid analog were undertaken. Rat in vivo evaluation of these newly identified compounds as their poly (lactide-co-glycolide) microsphere formulation, from which sustained release of the test compound is possible, led us to discover compounds that showed efficacy in a rat bone fracture healing model after its topical administration without serious influence on blood pressure and heart rate. A structure-activity relationship study is also presented. (C) 2012 Elsevier Ltd. All rights reserved.

  A pharmaceutical composition for topical administration for prevention and/or treatment of diseases associated with decrease in bone mass comprising an EP 4 agonist as an active ingredient. An EP 4 agonist, in which includes a compound possessing prostaglandin skeleton as a representative, possesses promoting action on bone formation, so it is useful for prevention and/or treatment of diseases associated with decrease in bone mass (bone diseases such as primary osteoporosis, secondary osteoporosis, bone metastasis of cancer, hypercalcemia, Paget's disease, bone loss and bone necrosis, postoperative osteogenesis, alternative therapy for bone grafting).

  一种用于局部治疗预防和/或治疗与骨量减少相关疾病的药物组合物，包括EP4激动剂作为活性成分。EP4激动剂，其中包括具有前列腺素骨架的化合物作为代表，具有促进骨形成的作用，因此对于预防和/或治疗与骨量减少相关的疾病（如原发性骨质疏松症、继发性骨质疏松症、骨癌转移、高钙血症、帕吉特病、骨丢失和骨坏死、术后骨生成、骨移植替代疗法）非常有用。
