position of the α-tetralone moiety is a requirement for MAO-A and MAO-B inhibition, and that a benzyloxy substituent on this position is more favourable for MAO-A inhibition than phenylethoxy and phenylpropoxy substitution. For MAO-B inhibition, alkyl and halogen substituents on the meta and para positions of the benzyloxy ring enhance inhibitory potency. It may be concluded that α-tetralone derivatives
在本研究中,合成了一系列15种α-四氢萘酮(3,4-dihydro-2 H-萘-1-酮)衍生物,并作为重组人单胺氧化酶(MAO)A和B的抑制剂进行了评估。所研究的四氢萘酮衍生物在结构上与一系列色酮(1-苯并吡喃-4-酮)衍生物有关,该酮先前已被证明可充当MAO-B抑制剂。结果表明,α-四氢萘酮是高效的MAO-B抑制剂,所有化合物的IC 50值均在纳摩尔范围内(<78 nM)。尽管大多数化合物是MAO-B的选择性抑制剂,但α-四氢萘酮类也是有效的MAO-A抑制剂,其中十种化合物的IC 50均达到IC 50值在纳摩尔范围内(<792 nM)。最有效的MAO-B抑制剂6-(3-碘苄氧基)-3,4-二氢-2 H-萘-1-酮的IC 50值为4.5 nM,对MAO-B的选择性为287倍MAO-A异构体,而最有效的MAO-A抑制剂6-(3-氰基苄氧基)-3,4-二氢-2 H-萘-1-酮的IC 50MAO-A的选择性为24
