4α/β-acyloxypodophyllotoxin derivatives were synthesized, and were evaluated against the pre-third-instar larvae of B. mori, A. dissimilis and M. separate in vivo at the concentration of 1 mg ml−1, respectively. Among all derivatives, compounds 2 g, h and 4c, d showed more promising insecticidal activities than their precursors – podophyllotoxin and epipodophyllotoxin. Furthermore, derivatives 2 g, h and 4c, d exhibited
由于我们在基于天然产物杀虫剂的研究正在进行的工作,一些4α/β-acyloxypodophyllotoxin衍生物的合成,反对的预第三龄幼虫进行了评价家蚕,A. dissimilis和M.分开体内分别为1 mg ml -1的浓度。在所有衍生物中,化合物2 g,h和4c,d显示出比其前体鬼臼毒素和表鬼臼毒素更有希望的杀虫活性。此外,导数2 g,h和4c,d与前体鬼臼毒素和表鬼臼毒素相比,它们显示出更多的相对友好活性。该结果表明鬼臼毒素衍生物中的4β-酰氧基部分对于获得更有效的化合物是重要的。
