the first target specific, highly diastereoselective synthesis of new class of pyranoquinolinyl/furoquinolinyl-acrylic acid diastereomers and evaluation of their invitro α-glucosidase inhibitory activity. All the products were thoroughly characterized by 1H NMR, 13C NMR, FT-IR, Mass spectral and CHN analysis. A highly diastereoselective target specific route of synthesis for the biologically active
在本研究中,我们报告了新型的吡喃喹啉基/呋喃喹啉基-丙烯酸非对映异构体的第一个靶标特异性,高非对映选择性合成方法,并对它们的体外α-葡萄糖苷酶抑制活性进行了评估。所有产物均通过1 H NMR,13 C NMR,FT-IR,质谱和CHN分析进行了彻底表征。通过使用手性三(3-七氟丙基羟甲基)]-(-)-樟脑phor(A)或三[3-(三氟甲基)羟甲基]-(+)-樟脑(B)。发现在所获得的一组4个非对映体产物中,吡喃喹啉基丙烯酸加合物的外对映体表现出相对较高的α-葡糖苷酶抑制活性。与标准阿卡波糖(IC50 = 0.65±0.02μM)相比,新合成的化合物的IC50值在(0.40±0.02-30.3±0.84μM)范围内。发现发现化合物11a,11c,11d和12d比标准阿卡波糖更具活性。还发现未取代的化合物(11a)或具有氯或甲氧基取代基的化合物(11c,11d,12d)显示出潜在的α-葡糖苷酶
