s and 2-fluoro-2-phenylcyclopropylalkylamines, as well as 2-fluoro-1-phenylcyclopropylamines and 2-fluoro-1-phenylcyclopropylmethylamines, were synthesized in order to study the effects of fluorine substitution on monoamine oxidase inhibition. Inhibitory activity was assayed using commercially available microbial tyramine oxidase. Characterization of tyramine oxidase, carried out prior to the inhibition
为了研究效果,合成了两个非对映体纯的苯基环丙胺类似物2-氟-2-苯基环丙胺和2-氟-2-苯基环丙基烷基胺,以及2-氟-1-苯基环丙胺和2-氟-1-苯基环丙基甲胺。取代对单胺氧化酶抑制的影响 使用可商购的微生物酪胺氧化酶测定抑制活性。在抑制实验之前进行酪胺氧化酶的表征,证实了较早的建议,即该酶是对氨基脲敏感的含铜单胺氧化酶。最有效的竞争性抑制剂是反式-2-氟-2-苯基环丙胺,其IC(50)值比非氟化化合物tranylcypromine低10倍。发现2-氟-1-苯基环丙基甲基胺是酪胺氧化酶的弱非竞争性抑制剂。直接与环丙烷环键合的游离氨基和与氨基成顺式关系的氟原子的存在是增加酪氨酸氧化酶抑制作用的结构特征。
