organic syntheses. IC50 values for inhibition were determined for compounds 5, 10 and 15 in order to determine their specificity for binding to MAO-B. Compound 5 inhibited MAO-B with an IC50 of 664 ± 48.08 nM. No further investigation was carried out with this compound. Compound 10 inhibited MAO-B with an IC50 of 208.5 ± 13.44 nM and compound 15 featured an IC50 of 131.5 ± 0.71 nM for its MAO-B inhibitory
该项目的目的是合成和评估三种新型的炔丙基胺的氟18标记的衍生物,作为潜在的PET放射性配体,以可视化单胺氧化酶B(MAO-B)的活性。 炔丙胺的三种氟化衍生物((S)-1-氟-N,4-二甲基-N-(丙-2-炔基)-戊-4-烯-2-胺(5),(S)-N -(1-氟-3-(呋喃-2-基)丙-2-基)-N-甲基丙-2-yn-1-胺(10)和(S)-1-氟-N,4-二甲基- ñ - (丙-2-炔基)戊-2-胺(15))在多步有机合成方法合成。IC 50个测定为化合物为抑制值5,10和15为了确定它们与MAO-B结合的特异性。化合物5抑制MAO-B,IC 50为664±48.08 nM。没有对该化合物进行进一步的研究。化合物10抑制MAO-B的IC 50为208.5±13.44 nM,化合物15具有抑制MAO-B的IC 50为131.5±0.71 nM。没有一种化合物能抑制MAO-A活性(IC 50
