2, 3-Dioxopiperazine derivatives, which are antitumor agents of a new type, were synthesized and the structure-activity relationship was investigated from the viewpoint of lipophilic-hydrophilic balance. It was found that 1-(4-diethylaminobenzyl)-4-n-hexyl-2, 3-dioxopiperazine (12n) possessed significant in vitro cytotoxicity and in vivo antitumor activity against transplanted tumor, but this in vivo antitumor activity did not reflect the in vitro cytotoxicity. The metabolism of 12n in rats and mice was then studied. It was found that the Et2N-group of 12n was easily metabolized to an AcNH-group in vivo.
一种新型抗癌剂——2,3-二氧哌嗪衍生物被合成,并且从亲脂-亲水平衡的角度探讨了其构效关系。研究发现,1-(4-二乙氨基苄基)-4-正己基-2,3-二氧哌嗪(12n)具有显著的体外细胞毒性和体内抗移植瘤活性,但这种体内抗癌活性并未反映出其体外细胞毒性。接下来对12n在大鼠和小鼠体内的代谢进行了研究。结果发现,12n的Et2N基团在体内易于代谢为AcNH基团。
