is performed by the MOBY DIGS package. Five selected descriptors are as follows: one two-dimensional (2D) autocorrelation descriptor (GATS4e), one edge adjacency indice (EEig06x), one RDF descriptor (RDF080v), one three-dimensional (3D) MoRSE descriptor (Mor09v), and one atom-centered fragment (H-052) descriptor. Quantitative structure–activity relationship studies demonstrated that the insecticidal
在继续进行旨在发现和开发基于天然产物的杀虫剂的程序的过程中,合成了33个在C和D环上修饰的鬼臼毒素和鬼臼毒素的肟衍生物,并通过质子核磁共振(1 H NMR)对其结构进行了表征。),高分辨率质谱(HRMS),电喷雾电离质谱(ESI-MS),旋光度,熔点(mp)和红外(IR)光谱。化合物5e,5f和9f的立体化学构型通过X射线晶体学确定。评估了它们对北方夜蛾蠕虫Mythimna separata(Walker)的三龄前幼虫的杀虫活性,体内。化合物5e,9c,11g和11h的杀虫活性尤其优于太桑丹宁,太桑丹宁是从Mel子草中提取的市售植物杀虫剂。。MOBY DIGS软件包执行了结合了多元线性回归(GA-MLR)计算的遗传算法。五个选定的描述符如下:一个二维(2D)自相关描述符(GATS4e),一个边缘邻接索引(EEig06x),一个RDF描述符(RDF080v),一个三维(3D)MoRSE描述符
