determined by IR, (1)H NMR and mass spectroscopy, in addition, representative single-crystal structures were characterized by using X-ray diffraction analysis. Preliminary biological evaluation showed that the compounds could inhibit the growth of A549 cells in dosage- and time-dependent manners. The study on structure-activity relationships showed that compounds with 4-chlorophenyl group at pyrazole moiety
通过3-芳基-1-(2-溴乙基)-1H-吡唑-5-羧酸乙酯与胺的反应,合成了一系列新颖的吡唑并[1,5-a]吡嗪-4(5H)-衍生物。一般加热条件和微波辅助条件。通过IR,(1)H NMR和质谱确定化合物的结构,此外,通过使用X射线衍射分析表征代表性的单晶结构。初步生物学评估表明,该化合物可以剂量和时间依赖性抑制A549细胞的生长。结构-活性关系的研究表明,吡唑部分具有4-氯苯基的化合物,例如5-苄基-2-(4-氯苯基)-6,7-二氢吡唑并[1,5-a]吡嗪-4(5H) )-1(3o)具有更大的抑制作用。
