compounds for the control of Brontispa longissima larvae, eight spin-labeled camptothecin derivatives 7a–h and the intermediate 2 were first tested for their insecticidal activities against fifth-instar larvae of Brontispa longissima. Among all the tested compounds, especially compounds 7a and 2 showed promising insecticidal activities with the corrected mortality rates of 69.55% and 74.07% against
继续我们寻找基于天然产物的化合物来控制 Brontispa longissima 幼虫,首先测试了八种自旋标记的喜树碱衍生物 7a-h 和中间体 2 对 Brontispa longissima 的五龄幼虫的杀虫活性。在所有测试的化合物中,尤其是化合物7a和2显示出有希望的杀虫活性,对B. longissima 5龄幼虫的校正死亡率分别为69.55%和74.07%。这些化合物的不同杀虫活性范围表明这些化合物中l-氨基酸结构的变化显着影响了该类化合物的活性谱,并从中揭示了一些重要的SAR信息。© 2011 Wiley Periodicals, Inc. 杂原子化学 22:687–691, 2011; 在 wileyonlinelibrary.com 上在线查看这篇文章。DOI 10.1002/hc.20734
