molecules capable of inhibiting transcription initiation in bacteria has resulted in the synthesis of N,N′-disubstituted hydrazines and imine-carbohydrazides comprised of indole, pyridine, pyrrole, furan and thiophene using the respective trichloroacetyl derivatives, carbohydrazides and aldehydes. Replacement of the indole moiety by smaller heterocycles linked by CONHNC linkers afforded a broad variety
寻找能够抑制细菌中转录起始的小分子已导致使用各自的三氯乙酰基衍生物,碳酰肼和醛合成了N,N'-二取代的肼和亚胺-碳酰肼,它们由吲哚,吡啶,吡咯,呋喃和噻吩组成。由较小的杂环由连接的吲哚部分的代用CO NH Ñ Ç接头得到各种各样有效地靶向RNA聚合酶化合物的σ 70 / σ甲相互作用如通过ELISA测定和表现出增加的生长的抑制大肠杆菌相比枯草芽孢杆菌在培养中。通过分子建模和结构-活性关系(SAR)研究,确定了抗菌活性所需的合成转录起始抑制剂的结构特征。
