AbstractThis paper focuses on the design and antitubercular activity of molecules which are a hybrid of coumarin and pyrimidine nuclei. A set of 16 compounds, viz. 4-(substituted)phenyl-3,4-dihydro-1H-chromino[4,3-d]pyrimidine-2,5-diones and 4-(substituted)phenyl-2-thioxo-3,4-dihydro-1H-chromino[4,3-d]pyrimidin-5-ones have been synthesized using green chemistry principles and evaluated for antitubercular activity
摘要本文着重研究香豆素和嘧啶核的杂合分子的设计和抗结核活性。一组16种化合物,即。4-(取代)苯基-3,4-二氢-1 H-苯并[4,3-d]嘧啶-2,5-二酮和4-(取代)苯基-2-硫代-3,4-二氢-1 H -chromino [4,3-d] pyrimidin-5-ones已使用绿色化学原理合成,并通过微孔板Alamar蓝测定法(MABA)和基于发光的低氧回收测定法(LORA)利福平作为抗真菌活性进行了评估标准。使用带有驱动细菌荧光素酶的乙酰胺酶启动子的质粒培养LORA所需的结核分枝杆菌H37Rv菌株基因用于信号增强,并使其适应发酵罐中的低氧含量。化合物5d,5e和5g表现出最大的抗结核活性,基于MABA的%抑制值为58、55和45,基于128μM的LORA测试的抑制值为62、35和37。为了了解结构和活动之间的关系,开发了递归分区(RP)模型。建立了两种不同的RP模型,一种基于抗结核
