investigated for MAO and ChE inhibition properties. Most of the compounds showed preferential inhibition towards MAO-B. Compound 4, (1-(1-(4-Bromophenyl)ethylidene)-4-(5-nitrothiazol-2-yl)semicarbazide) emerged as lead candidate (IC50 = 0.212 µM, SI = 331.04) against MAO-B; whereas compounds 21 1-(5-Bromo-2-oxoindolin-3-ylidene)-4-(5-nitrothiazol-2-yl)semicarbazide (IC50 = 0.264 µM) and 17 1-((4-Chlorophenyl)
设计,合成和研究了一系列2-氨基-5-硝基噻唑衍生的半咔唑类化合物对MAO和ChE的抑制性能。大多数化合物显示出对MAO-B的优先抑制。化合物4(1-(1-(4-溴苯基)亚乙基)-4-(5-硝基噻唑-2-基)半咔唑)作为抗MAO-B的候选候选化合物(IC50 = 0.212 µM,SI = 331.04);而化合物21 1-(5-Bromo-2-oxoindolin-3-yylne)-4-(5-nitrothiazol-2-yl)semicarbazide(IC50 = 0.264 µM)和17 1-((4-Chlorophenyl)(phenyl)亚甲基)-4-(5-硝基噻唑-2-基)氨基脲(IC50 = 0.024 µM)分别作为AChE和BuChE的铅抑制剂。化合物21的活性几乎等同于他克林。动力学研究表明,化合物4表现出竞争性和可逆性MAO-B抑制,而化合物21和17分别表现出混合
