  摘要：

  作为用于治疗2型糖尿病的潜在药物，二肽基肽酶IV（DPP-IV）抑制剂已引起人们的关注，因为它们可防止胰高血糖素样肽1（GLP-1）降解并延长其作用时间。我们之前曾报道过2-氰基-4-氟吡咯烷类可作为有效的DPP-IV抑制剂，并且已经在吡咯烷的1位上进行修饰以获得更有用的抑制剂。发现L-叔丁基甘氨酸衍生物是稳定且有效的DPP-IV抑制剂，其在体内表现出降低葡萄糖的作用。在这里，我们报告上述衍生物的合成和生物学数据。

  The present invention provides a controlled release composition showing release of an active ingredient (proton pump inhibitor) controlled in two or more steps at different release rates, which contains 1) a release-controlled part A capable of controlling release of the active ingredient to occur at a predetermined rate, 2) a release-controlled part B capable of controlling release of the active ingredient to occur at a predetermined rate lower than the release rate of the release-controlled part A, and where necessary, 3) a release-controlled part C capable of controlling release of the active ingredient to occur at a predetermined rate faster than the release rate of the release-controlled part B, wherein the release of the active ingredient from the release-controlled part B precedes the release of the active ingredient from the release-controlled part A (when release-controlled part C is contained, the release of the active ingredient from the release-controlled part C precedes the release of the active ingredient from the release-controlled part B).

  本发明提供了一种控制释放组合物，该组合物显示出活性成分（质子泵抑制剂）在不同的释放速率下控制释放，其中包括1）能够控制活性成分以预定速率释放的释放控制部分A，2）能够控制活性成分以比释放控制部分A更低的预定速率释放的释放控制部分B，必要时还包括3）能够控制活性成分以比释放控制部分B更快的预定速率释放的释放控制部分C，其中活性成分从释放控制部分B的释放先于从释放控制部分A的释放（当包含释放控制部分C时，从释放控制部分C的释放先于从释放控制部分B的释放）。
