  摘要：

  A novel series of beta-amino amides incorporating fused heterocycles, i.e., triazolopiperazines, were synthesized and evaluated as inhibitors of dipeptidyl peptidase IV (DPP-IV) for the treatment of type 2 diabetes. (2R)-4-Oxo-4-[3-(trifluoromethyl)-5,6-dihydro[1,2,4]triazolo[4,3-a]pyrazin-7(8H)-yl]-1-(2,4,5-trifluorophenyl)butan-2-amine (1) is a potent, orally active DPP-IV inhibitor (IC(50) = 18 nM) with excellent selectivity over other proline-selective peptidases, oral bioavailability in preclinical species, and in vivo efficacy in animal models. MK-0431, the phosphate salt of compound 1, was selected for development as a potential new treatment for type 2 diabetes.

  设计和合成作为二肽基肽酶IV抑制剂的4-（2,4,5-三氟苯基）丁烷-1,3-二胺

  摘要：

  糖尿病在世界范围内的流行已激发了许多有关开发新的抗糖尿病药物的研究。结果，二肽基肽酶IV（DPP4）被认为是经过验证的靶标。为了发现新的DPP4抑制剂，我们分析了Protein Data Bank中DPP4的复杂结构，并设计了一系列三唑化合物。通过酶活性测定和结合相互作用模式的晶体学验证，我们发现三唑化合物可通过微摩尔IC 50抑制DPP4。价值观。在该系列上进行了肝微粒体稳定性和细胞色素P450代谢测试，揭示了三唑化合物的不良药代动力学特征。为了克服这一责任，我们用酰胺或脲基团取代了三唑环，以生产一系列新的DPP4抑制剂。基于其酶活性，代谢稳定性以及对DPP8和DPP9的选择性，我们选择了化合物21 r进行口服葡萄糖耐量试验（OGTT），以进一步研究其在小鼠体内的作用。结果显示，在3mg kg -1的剂量下21 r具有与西他列汀相似的功效。21 r的晶体结构 与DPP4结合的结果还表明，
