administration. Despite its good potency in vitro, the high lipophilicity of 1 is a concern in long-term in vivo studies. Further medicinal chemistry efforts identified 4 as an improved lead compound with good in vitro ADME profile applicable to long term in vivo studies. A rat fracture study was conducted with 4 for 4 weeks to validate its utility in bone fracture healing. The results suggest that this
我们描述了一种药物
化学方法,可发现具有高效力和良好药代动力学的新型EP 1拮抗剂。我们的出发点是1,一种EP 1受体拮抗剂,在静脉内给药后在膀胱测量模型中显示出药理学功效。尽管其在体外具有良好的效能,但长期的体内研究仍关注1的高亲脂性。进一步的药物
化学努力将4鉴定为具有良好体外A
DME谱的改良
铅化合物,适用于长期体内研究。一项大鼠骨折研究进行了4持续4周以验证其在骨折愈合中的效用。结果表明,该EP 1受体拮抗剂刺激愈伤组织形成,因此4具有增强骨折愈合的潜力。
