derivatives were designed and synthesized in high yields to assess their inhibitory activity and selectivity against human monoamine oxidase A and B. The most important chiral compounds were separated into their single enantiomers and tested. The impact of the substituents at N1, C3 and C5 positions as well the influence of the configuration of the C5 on the biological activity were analyzed. Bulky
以高收率设计并合成了新的N-乙酰基/ N-硫代氨基甲酰基吡唑啉衍生物,以评估其对人单胺氧化酶A和B的抑制活性和选择性。将最重要的手性化合物分离为单一对映体并进行测试。分析了取代基在N1,C3和C5位置的影响以及C5构型对生物活性的影响。在C5的大的芳香族基团是不能容忍的。C3上的对-苯甲酰氧基芳基部分使选择性朝向B同工型。分子模型研究也证实了这一结果,为合成特权结构提供了新的建议,这些特权结构可作为治疗情绪障碍和神经退行性疾病的先导化合物。
