The present investigation was undertaken to find more effective autitumor agents than 1-(4-diethylaminobenzyl)-4-n-hexyl-2, 3-dioxopiperazine (1), which was found in our laboratory in previous studies. 1-(4-Diethylamino-3- or 2-substituted benzyl)-2, 3-dioxopiperazine derivatives and 1-(4-substituted aminobenzyl)-2, 3-dioxopiperazine derivatives were designed and synthesized with the aim of suppressing the metabolism of the Et2N- group of 1. The structureactivity relationships and metabolism of these compounds were studied. It was found that 1-benzyl-4-[4-(2-pyrimidinylamino)benzyl]-2, 3-dioxopiperazine (17c) possessed the highest in vitro and in vivo activities.
本研究旨在寻找比 1-(4-二乙基氨基苄基)-4-正己基-2, 3-二氧代哌嗪(1)更有效的自体瘤药剂,我们实验室在以前的研究中发现了这种药剂。为了抑制 1 的 Et2N-基团的代谢,我们设计并合成了 1-(4-二乙基氨基-3-或 2-取代苄基)-2,3-二氧代哌嗪衍生物和 1-(4-取代氨基苄基)-2,3-二氧代哌嗪衍生物。结果发现,1-苄基-4-[4-(2-嘧啶基氨基)苄基]-2,3-二氧代哌嗪(17c)具有最高的体外和体内活性。
