antimicrobial activity of substituted hydrazides. To understand the relationship between physicochemical parameters and antimicrobial activity of substituted hydrazide derivatives, QSAR investigation was performed by the development of one-target and multi-target models. The multi-target model was found to be effective in describing the antimicrobial activity of substituted hydrazides in comparison to the
合成了一系列取代的酰肼衍生物,并对其进行了体外筛选对五种代表性微生物的抗菌活性。抗菌研究的结果表明,苯甲酸部分上吸电子基团的存在提高了抗菌活性。此外,杂环呋喃的存在不能改善取代的酰肼的抗微生物活性。为了解取代酰肼衍生物的理化参数与抗菌活性之间的关系,通过开发一靶标和多靶标模型进行了QSAR研究。与单靶标模型相比,发现多靶标模型可有效描述取代的酰肼的抗菌活性。此外,它还表明了拓扑参数,价三阶分子连接指数(3 χ v)和电子参数,最高能量在描述被取代的酰肼的抗微生物活性占据分子轨道(HOMO)。
