generation DPP-4 inhibitors, we endeavored to identify distinct structures with long-acting (once weekly) potential. Taking advantage of X-ray cocrystal structures of sitagliptin and other DPP-4 inhibitors, such as alogliptin and linagliptin bound to DPP-4, and aided by molecular modeling, we designed several series of heterocyclic compounds as initial targets. During their synthesis, an unexpected chemical
在开发第二代DPP-4抑制剂的过程中,我们努力确定具有长效作用(每周一次)的独特结构。利用西他列汀和其他DPP-4抑制剂(例如与DPP-4结合的阿格列汀和利拉列汀)的X射线共晶体结构,并借助分子建模,我们设计了一系列杂环化合物作为初始靶标。在其合成过程中,意外的化学转化提供了一种新颖的三环支架,这超出了我们的原始设计。利用这一偶然发现,我们将这种支架制成了非常有效和选择性的DPP-4抑制剂前导序列,如化合物17c所强调的那样。
