stimulate insulin secretion in a glucose-dependent manner. In the present study, we have developed three series of substituted N-(thieno[2,3-b]pyridin-3-yl)-guanidine (2a-l), N-(1H-pyrrolo[2,3-b]pyridin-3-yl)-guanidine (3a-l), and N-(1H-indol-3-yl)-guanidine (4a-l) as new class of antidiabetic agents. In vitro glucose-dependent insulinotropic activity of test compounds 2a-l, 3a-l, and 4a-l was evaluated using
磺脲类药物可独立于血糖浓度刺激胰岛素分泌,因此会在2型糖尿病患者中引起低血糖症。在过去的几年中,已发现许多芳基-咪唑啉衍生物以葡萄糖依赖性方式刺激胰岛素的分泌。在本研究中,我们开发了三个系列的取代N-(硫代[2,3-b]吡啶-3-基)-胍(2a-1),N-(1H-吡咯并[2,3-b]吡啶-3-基)-胍(3a-1)和N-(1H-吲哚-3-基)-胍(4a-1)是新型的抗糖尿病药。使用基于RIN5F(大鼠胰岛素样瘤细胞)的测定评估测试化合物2a-1、3a-1和4a-1的体外葡萄糖依赖性促胰岛素活性。所有测试化合物仅在存在葡萄糖负荷(16.7mmol)时才显示出浓度依赖性的胰岛素分泌。一些测试化合物(2c,3c,
