with several analogs were synthesized and evaluated for in vitro inhibition of dipeptidyl peptidase IV. The experimental data indicated that most designed compounds exhibited significant dipeptidyl peptidase IV inhibitory activity. Among them, compounds 35f displayed the greatest potency against dipeptidyl peptidase IV in vitro with the IC50 value of 78 nm. In an oral glucose tolerance test in normal
抑制二肽基肽酶IV是治疗2型糖尿病的重要方法。在这项研究中,我们报告了一个多阶段虚拟筛选工作流程,该工作流程集成了3D药效团模型,结构共有停靠和分子力学/广义Born表面积结合能计算,以识别新型二肽基肽酶IV抑制剂。在筛选了我们的内部数据库后,确定了两种命中化合物HWL-405和HWL-892,它们在虚拟筛选的所有阶段均具有持久的高性能。合成了这两种命中化合物以及几种类似物,并评估了其对二肽基肽酶IV的体外抑制作用。实验数据表明,大多数设计的化合物均显示出显着的二肽基肽酶IV抑制活性。他们之中,化合物35f在体外显示出对二肽基肽酶IV的最大效力,IC50值为78 nm。在正常雄性昆明小鼠的口服葡萄糖耐量试验中,化合物35f以剂量依赖性方式降低了血糖偏移。
