compounds screened for activity, 9 phenylpropanoates, 3 cinnamates, and 4 benzoates were found to be highly active antifeedants. To understand the structure-activity relationships of these compounds, a multivariate analysis study was performed. A number of molecular and substituent descriptors were calculated and correlated to results from two-choice feeding tests with H. abietis. Three local models were developed
在松树象鼻虫(Hylobius abietis)上测试了主要是苯丙酸酯,肉桂酸酯和苯甲酸酯的拒食活性。在筛选出活性的105种化合物中,发现9种苯基丙酸酯,3种肉桂酸酯和4种苯甲酸酯是高活性的拒食剂。为了了解这些化合物的构效关系,进行了多变量分析研究。计算了许多分子和取代基描述子,并将其与由过双歧杆菌进行的二选饲喂试验的结果相关联。建立了三个具有良好内部预测能力的局部模型。外部测试集显示出中等预测性。通常,低极性,小尺寸和高亲脂性是具有良好拒食活性的化合物的特征。
