The present invention relates to certain N-(substituted glycyl)-2-cyanopyrrolidines of formula I
1
wherein Y is as defined herein, in free form or in acid addition salt form. Compounds of formula I inhibit DPP-IV (dipeptidyl-peptidase-IV) activity. They are therefore indicated for use as pharmaceuticals in inhibiting DPP-IV and in the treatment of conditions mediated by DPP-IV, such as non-insulin-dependent diabetes mellitus, arthritis, obesity, osteoporosis and further conditions of impaired glucose tolerance.
本发明涉及某些 N-(取代的甘
氨酰)-
2-氰基吡咯烷,其式为 I
1
其中 Y 如本文所定义,以游离形式或酸加成盐形式存在。式 I 的化合物可抑制
DPP-IV(二肽基肽酶-IV)的活性。因此,它们可用作抑制
DPP-IV 和治疗由
DPP-IV 介导的疾病的药物,如非
胰岛素依赖型糖尿病、关节炎、肥胖症、骨质疏松症和其他糖耐量受损疾病。
