A series of fluorine and iodine analogues of clorgyline was synthesized and evaluated for inhibitory potency and selectivity toward monoamine oxidase A (MAO-A). Among them, N-[3(2, 4-dichloro-6-iodophenoxy)propyl]-N-methyl-2-propynylamine (3d), N-[3-(4-chloro-2-fluorophenoxy)propyl]-N-methyl-2-propynylamine (3f) and N-[3-(2-chloro-4-fluorophenoxy)propyl]-N-methyl-2-propynylamine (3g) were found to have high inhibitory potency and selectivity toward MAO-A comparable to those of clorgyline itself. Thus, they were considered for advanced development as radiofluorinated and radioiodinated ligands that may be useful for functional MAO-A studies in the living brain with positron emission tomography and single photon emission computer tomography.
合成了一系列氯吉林的氟和碘类似物,并评估了其对单胺氧化酶 A (MAO-A) 的抑制效力和选择性。其中,N-[3(2,4-二氯-6-碘苯氧基)丙基]-N-甲基-2-丙炔胺(3d)、N-[3-(4-氯-2-氟苯氧基)丙基]-N发现-甲基-2-丙炔胺 (3f) 和 N-[3-(2-氯-4-氟苯氧基)丙基]-N-甲基-2-丙炔胺 (3g) 对 MAO-A 具有高抑制效力和选择性与氯吉林本身的效果相当。因此,它们被认为是作为放射性氟化和放射性碘化配体进行高级开发,可能有助于利用正电子发射断层扫描和单光子发射计算机断层扫描对活体大脑进行功能性 MAO-A 研究。
