corresponding chalcones. These corresponding chalcones were reacted with hydrazine hydrate, urea, thiourea, and hydroxylamine hydrochloride, which led to the formation of corresponding novel pyrazole, pyrimidine, and isooxazole derivatives, respectively. All newly synthesized compounds were evaluated for their antimycobacterial activities against Mycobacterium tuberculosis using agar dilution. The results
在本研究中,4-硝基苯乙酮与适当的醛在乙醇氢氧化钠溶液中缩合,生成相应的查耳酮。这些相应的查耳酮与水合肼,尿素,硫脲和羟胺盐酸盐反应,分别导致形成相应的新型吡唑,嘧啶和异恶唑衍生物。使用琼脂稀释液评估所有新合成的化合物对结核分枝杆菌的抗分枝杆菌活性。结果表明,大多数化合物具有更好的体外抗结核活性,化合物1g的MIC为1.56μgmL -1。QSAR分析表明,分子描述符意味着电性状态(MS)和平均化合价的连接性指数卡0(0 χ平均),而3-路径的Kierα-改性形状指数(积极的贡献3 κ α)带负贡献。我们研究的目的是产生新的线索并优化其结构以显示有效的功效。
