合成了一系列吡唑啉衍生物,并通过IR,1 H NMR,13 C NMR,质谱和元素分析对它们的结构进行了表征。该新化合物被设计为结核分枝杆菌iki酸酯激酶(MtSK)抑制剂基于使用Sybyl-X 2.0软件的对接研究。在计算机模拟中ADMET的预测表明,所有化合物均具有最小的毒性作用,并具有良好的吸收性和溶解性。因此,这些化合物可作为开发新的抗结核药物的潜在先导化合物。在测试的化合物4c,5b和6a中,它们显示出有希望的抗结核活性。另外,还使用色氨酸蓝排除法评估了某些化合物对EAC细胞系的细胞毒活性。

In an effort to develop selective MAO (monoamine oxidase) B inhibitors, structure based virtual screening was initiated on an in-house library. Top 10 HITS were synthesized and evaluated for MAO (A and B) inhibitory activity, both against human and rat enzymes. All the compounds were found selective, reversible and active in nM range (100 times more potent than selegeline) towards MAO-B. Outstanding co-relation between predicted and experimental K(i) values were observed. (C) 2011 Elsevier Ltd. All rights reserved.
