In the present work, a series of new coumarino-azetidinones (3a-l) were designed, synthesized and evaluated for biological activities. The newly synthesized compounds (3a-l) were fully characterized by several spectroscopic techniques and elemental analyses. The synthesized compounds (3a-l) were screened for their preliminary in-vitro antitubercular and antimicrobial activities. Almost all the coumarino-azetidinones
在本工作中,设计,合成并评估了一系列新的香豆素-氮杂环丁烷酮(3a-1)的生物活性。通过几种光谱技术和元素分析对新合成的化合物(3a-1)进行了全面表征。筛选合成的化合物(3a-1)的初步体外抗结核和抗菌活性。几乎所有香豆素-氮杂环丁烷酮对结核分枝杆菌(M. tuberculosis) H 37均显示出有希望的活性Rv株。相反,一些香豆素-氮杂环丁烷酮显示出有趣的抗菌活性。此外,测试了大多数活性化合物的细胞毒性研究,并对Vero细胞表现出低水平的细胞毒性。最后但并非最不重要的一点是,分子对接结果显示与结核分枝杆菌InhA-D148G突变体(PDB。4TZK)和大肠杆菌(E. coli)(PDB。4JX8)有极好的相互作用。生物学评估的结果表明,香豆素-氮杂环丁烷酮是有望用于后续研究以寻找新的抗结核和抗菌药物的先导化合物。
