The synthesis and physicochemical properties of a series of N-[N',N'-disubstituted-amino)acetyl]arylamines are described. A QSAR method is applied to local anesthetic activity and acute toxicity by means of a "nonclassic" substituent variation involving a modification on both aryl and amino moieties. The choice of the different parameters (partition coefficient, pKa, connectivity index, molar refraction
描述了一系列N- [N',N'-二取代-
氨基)乙酰基]芳基胺的合成和理化性质。Q
SAR方法通过涉及对芳基和
氨基部分的修饰的“非经典”取代基变化而应用于局部麻醉活性和急性毒性。讨论了不同参数(分配系数,pKa,连通性指数,摩尔折射和摩尔体积)的选择,并描述了它们的不同测定方法。摩尔折射是最能解释局部麻醉药活性变化的参数,MR的二次回归导致“后验”合成具有最佳活性的一种化合物。但是,分配系数是静脉毒性的最明确的参数。
