diabetic patients. In the present study we designed a novel series of 2-acetylbenzofuran hydrazones (L1-L7) and their metal (II) complexes Cu (II), Co (II), Zn (II) and Mn (II) (8–29) and screened for inhibitory activity against the yeast α-glucosidase. The synthesis of hydrazones incorporated the use of I2 as a catalyst which resulted in excellent yield of 94%. The ligand L3, showed good activity (IC50 = 47
抑制α-葡萄糖苷酶是设计抗糖尿病药物的重要方法之一,因为它在减少碳水化合物消化,避免糖尿病患者餐后血糖水平升高中起着重要的作用。在本研究中,我们设计了一系列新颖的2-乙酰基苯并呋喃(L1-L7)及其金属(II)络合物Cu(II),Co(II),Zn(II)和Mn(II)(8 – 29)并筛选了对酵母α-葡萄糖苷酶的抑制活性。的合成并入使用I 2作为催化剂,从而获得了94%的优异收率。配体L3表现出良好的活性(IC 50 与参考的阿卡波糖IC 50 = 378.25±0.12 µM相比, 它的金属络合物(10)表现出强大的活性(IC 50 = 1.15±0.001 µM)= 47.51±0.86 µM。类似地,在Cu(II)络合物与配体L5和L6显示出优异的α葡萄糖苷酶抑制(IC 50 = 0.15±0.003 12和0.21±0.002μM为13,分别地),而,钴(II),Mn的金属配合物(
