and acid–base dissociation constants of the compounds as well as with the calculated electronic properties of individual anilide substituents expressed as Hammett’s σ parameters. The substitution in the meta- or para-position of anilide of derivatives with higher lipophilicity by an electron-withdrawing moiety is favourable for higher activity. The optimum thermodynamic pK Ta value was found to be
摘要筛选了一系列环取代的3-羟基萘-2-甲酰苯胺对布鲁氏锥虫的野生型S427(血流形式)的体外活性。3-羟基-N-(3-三氟甲基苯基)-和3-羟基-N-(4-三氟甲基苯基)萘-2-甲酰胺显示出最高的生物活性(分别为MIC = 1.56和2.08μmol/ dm 3)。抗锥体虫活性与用表达为哈米特个别苯胺的取代基的所计算出的电子性质的化合物的以及试验确定亲脂性和酸-碱的解离常数相关σ参数。在meta或para中的替换具有较高亲脂性的衍生物的苯胺通过吸电子部分的位置有利于较高的活性。发现最佳热力学p K T a值为约。7.5。讨论了所有化合物的结构活性关系。 图形概要
