promising class of flavanone–metal ion complexes can act as selective cholinesterase inhibitors (ChEIs), which has led our group to synthesize a new series of flavanone derivatives (hesperidin, hesperetin, naringin, and naringenin) complexed to either copper (II) or zinc (II) and to evaluate their potential use as selective ChEIs. Most of the synthesized complexes exhibited greater inhibitory activity
金属螯合物强烈影响类黄酮中药理活性的性质和大小。近年来的研究表明,一类有前景的黄烷酮-金属离子络合物可以用作选择性胆碱酯酶抑制剂(ChEIs),这促使我们小组合成了一系列新的黄烷酮衍生物(橙皮苷,橙皮素,柚皮苷和柚皮苷)与铜(II)或锌(II)配合使用,并评估其作为选择性ChEIs的潜在用途。大多数合成的复合物对乙酰胆碱酯酶(AChE)的抑制作用均比对丁酰胆碱酯酶(BChE)的抑制作用强。这些复合物中有9种构成具有抑制力(IC 50)和抑制常数(K i)范围从0.02到4.5μM。具有黄烷酮-联吡啶衍生物的铜配合物提供了对AChE和BChE的最佳抑制活性。复杂的Cu(柚皮苷)(2,2'-联吡啶)(11)给出的huAChE的IC 50和K i值分别为0.012±0.002和0.07±0.01μM,低于标准加兰他敏( IC 50 = 206±30.0和K i = 126±18.0μM)。评
