  3-[2-((2S)-2-Cyano-pyrrolidin-1-yl)-2-oxo-ethylamino]-3-methyl-butyramide analogues as selective DPP-IV inhibitors for the treatment of type-II diabetes

  摘要：

  Based on the structures of NVP-DPP728 (1) and NVP-LAF237 (Vildagliptin, 2), three series of DPP-IV inhibitors were synthesized by linking substituted anilines, benzylamines, and phenylethylamines to (2S)-cyanopyrrolidine through a linker. More than 20 compounds were evaluated for their in vitro DPP-IV inhibition and selectivity profile over DPP-II, DPP8, and FAP enzymes. Selected compounds 5f and 7i showed in vivo plasma DPP-IV inhibition and inhibited glucose excursion in OGTT after oral administration in Wistar rats. Compound 5f (DPP-1V IC50 = 116 nM) has the potential for development as antidiabetic agent. (c) 2006 Elsevier Ltd. All rights reserved.

  the structure of the chiral auxiliary, which has allowed a diastereodivergent procedure to be set up for performing asymmetric aza-Michael reactions using the same chirality source. Finally, the adducts obtained in the asymmetric aza-Michael reaction have proven to be very versatile synthetic intermediates in the preparation of other interesting compounds such as β-amino esters, γ-amino alcohols, and

  金属苄酰胺与手性氨基醇衍生的α，β-不饱和酰胺的不对称aza-Michael反应（S，S）-（+）-伪麻黄碱已被详细研究。已经对最重要的实验参数（溶剂，温度，亲核体结构，添加剂的影响）进行了深入研究，表明该反应通常以良好的收率和非对映选择性进行，尽管必须根据取代条件修改实验条件共轭受体的模式。另外，在操纵手性助剂的结构时，观察到非常有趣的面部选择性反转，这允许建立非对映发散程序，以使用相同的手性来源进行不对称的aza-Michael反应。最后，
