As a contribution to the development of novel coumarin-oxime ether conjugates with therapeutically interesting properties, a series of coumarin-oxime ether (1a–1j) was synthesised using SN2 reaction of bromomethyl coumarins with butane-2,3-dione monoxime. Invitro anti-tuberculosis activityagainstMTBH37Rv strain was established for the coumarin-oxime ether (1a–1j). Most of the compounds exhibited significant
为了开发具有治疗意义的新型香豆素-肟醚共轭物,使用溴甲基香豆素与丁烷-2,3-二酮一肟的S N 2反应合成了一系列香豆素-肟醚(1a-1j)。针对香豆素-肟醚(1a – 1j)建立了针对MTBH 37 Rv菌株的体外抗结核活性。大多数化合物在0.04–3.12μgmL -1的最小抑菌浓度(MIC)下表现出显着的活性。化合物(1h)被鉴定为MIC值为0.04μgmL -1的命中候选物。,接近于异烟肼的MIC值(0.02μgmL -1),这是一种用于治疗肺结核的市售药物。化合物1h在Vero细胞中也表现出低水平的毒性和良好的体外安全性。还发现显示出有效的抗结核活性的化合物能更有效地裂解DNA,从而表现出核酸酶活性。进一步研究了活性最高的化合物(1h),以推论与模型血清蛋白牛血清白蛋白(BSA)的相互作用方式。
