Compounds of formulae (I A), (I B), (X A), (X B), (Y A) or (Y B) 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.
本发明涉及一种化合物。本发明涉及公式(I A)、(I B)、(X A)、(X B)、(Y A)或(Y B)的化合物,其中R'代表,R"代表氢、羟基、C1-C7烷氧基、C1-C8-烷酰氧基或R5R4N-CO-O-,其中R4和R5独立地为C1-C7烷基或苯基,该苯基未取代或取代物选自C1-C7烷基、C1-C7烷氧基、卤素和三氟甲基,其中R4还可以是氢;或R4和R5一起代表C3-C6烷基,以自由形式或以药学上可接受的酸加合盐的形式存在。公式(I A)、(I B)、(X A)、(X B)、(Y A)或(Y B)的化合物抑制DPP-IV(二肽基肽酶-IV)活性。因此,它们适用于作为药物用于抑制DPP-IV和治疗由DPP-IV介导的疾病,如非胰岛素依赖性糖尿病、关节炎、肥胖症、骨质疏松症和其他糖耐量受损的疾病。
