This research attempted to study the effect of lipophilicity on the anticancer activity of N-substituted norcantharimide derivatives. Twenty-three compounds were synthesized and their cytotoxicities against five human cancer cell lines studied. The lipophilicity of each derivative was altered by its substituent, an alkyl, alkyloxy, terpenyl or terpenyloxy group at the N-position of norcantharimide. Further, among all synthesized derivatives studied, the compounds N-farnesyloxy-7-oxabicyclo[2.2.1]heptane-2,3-dicarboximide (9), and N-farnesyl-7-oxabicyclo[2.2.1]heptane-2,3-dicarboximide (18), have shown the highest cytotoxicity, anti-proliferative and apoptotic effect against human liver carcinoma HepG2 cell lines, yet displayed no significant cytotoxic effect on normal murine embryonic liver BNL CL.2 cells. Their overall performance led us to believe that these two compounds might be potential candidates for anticancer drugs development.
本研究试图探讨脂亲和性对N取代氮卡那阳胺衍生物抗癌活性的影响。合成了23种化合物,并研究了它们对五种人类癌细胞系的细胞毒性。每种衍生物的脂亲和性受到其在氮位上取代基的影响,这些取代基包括烷基、烷氧基、萜基或萜氧基。此外,在所有合成的衍生物中,化合物N-法尼基氧基-7-氧双环[2.2.1]庚烷-2,3-二羧酰亚胺(9)和N-法尼基-7-氧双环[2.2.1]庚烷-2,3-二羧酰亚胺(18)显示出对人类肝癌HepG2细胞系的最高细胞毒性、抗增殖和诱导凋亡效应,但对正常小鼠胚胎肝BNL CL.2细胞未显示出显著的细胞毒性。它们的整体表现使我们相信这两种化合物可能是抗癌药物开发的潜在候选药物。
