zide (4a-4o) were designed and synthesized. The structures of the synthesized compounds were elucidated using FT-IR, 1H-NMR, 13C-NMR, and HRMS spectral data. The inhibitory activity of the compounds 4a-4o against hMAO-A and hMAO-B enzymes was evaluated by using in vitro Amlex Red® reagent based fluorometric method. Due to lots of high-cost kits including this assay, we determined the ingredients of
在目前的工作中,有15种新的N'-(亚芳基)-4-(1-(prop-2-yn-1-yl)-1H-苯并[d]咪唑-2-基)苯并肼(4a-4o)设计和合成。使用FT-IR,1H-NMR,13C-NMR和HRMS光谱数据阐明了合成化合物的结构。通过使用基于试剂的体外荧光法评估化合物4a-4o对hMAO-A和hMAO-B酶的抑制活性。由于包括该分析在内的试剂盒价格昂贵,因此我们从多家供应商的数据表中确定了试剂盒的成分,并通过使用各种浓度和体积的这些成分来调整了实验方案。因此,与市售MAO试剂盒一样,该试剂盒可进行快速,灵敏的测定,且成本和成分均比试剂盒清晰。酶抑制试验表明,合成的化合物具有针对hMAO-B的选择性抑制能力。化合物4e和4f对hMAO-B的IC50值分别为0.075μM和0.136μM。参比药物司来吉兰(IC50 = 0.040μM)和雷沙吉兰(IC50 = 0.066μM)也显示出
