单胺氧化酶(MAO)是线粒体外膜上的一种酶,可催化生物胺和外源性胺(如具有神经活性的血清素、去甲肾上腺素和多巴胺)的脱氨反应。单胺氧化酶存在两种同工型,即MAO-A和MAO-B。MAO-A主要分布在肠道、肝脏和外周肾上腺素能神经元中,可调节与情绪相关的神经递质,是抗抑郁药和抗焦虑药的关键作用靶点。除了在心理健康领域发挥作用外,MAO-A还会引发心脏组织的氧化应激,产生的过氧化氢可损伤线粒体并导致心力衰竭。因此,MAO-A抑制剂有望用于心血管疾病的治疗。MAO-A的高表达也与前列腺癌相关,抑制MAO-A可降低雄激素敏感型和雄激素抵抗型前列腺癌细胞的增殖能力。综上,MAO-A抑制剂在抑郁症、焦虑症、心力衰竭及部分癌症的治疗中具有潜在价值,使其成为药物研发的重要研究方向。
单胺氧化酶A(MAO-A)抑制剂筛选荧光检测试剂盒基于对过氧化氢的荧光检测法设计,用于筛选和表征人MAO-A的活性,过氧化氢是MAO-A底物氧化脱氨过程中产生的副产物之一。该试剂盒采用便捷的96孔板格式,配备了可完成100次酶反应的纯化MAO-A酶、底物、HydroRed探针、HydroRed显影剂以及检测缓冲液。
单胺氧化酶A(MAO-A)在氧气和水存在的情况下催化伯胺底物的氧化脱氨反应。MAO-A反应过程中产生的副产物过氧化氢(H₂O₂)可作为下游HydroRed显影反应的底物,该反应会氧化HydroRed探针,生成强荧光产物试卤灵。最终的荧光强度与MAO-A酶的活性呈正比。
