flavone MAO inhibitor studied is Az2k19 (1.6 mum for MAO-A, 2.1 mum for MAO-B), while Az1k15 and Az2k15 displayed better selectivity toward MAO-B (SI > 10). Docking studies are in accordance with our hypothesis that these inhibitors are most likely located at both the substrate cavity and the "aromatic cage". Our results show that it is considerable to develop new MAO inhibitors from C6 substitution of flavone
设计并使用6-N3 -2-苯基苯甲酮(Az1-Az2)和一系列N-苯并二甲基苯并色酮之间的点击化学反应(CuAAC反应)合成了针对单胺氧化酶两个活性位点(“芳香族笼”和底物腔)的黄酮衍生物新库。炔烃(k1-k20)。评价了它们对MAO同工型(MAO-A和MAO-B)的抑制活性。具有氟,酰胺键或氨基键的化合物显示出更好的抑制作用。研究的最有效的黄酮类MAO抑制剂是Az2k19(MAO-A为1.6 mM,MAO-B为2.1 mm),而Az1k15和Az2k15对MAO-B表现出更好的选择性(SI> 10)。对接研究符合我们的假设,即这些抑制剂最有可能位于基质腔和“芳香笼”中。
