合成了一系列胺取代的萘二甲酰亚胺类似物,并以10μM的单剂量浓度评估了针对60种肿瘤细胞系的体外抗肿瘤活性。这些新的类似物显示出对各种癌细胞系的潜在抗癌活性。化合物5d显示出显着的生长抑制,并且在五个剂量浓度水平下被评价为60个细胞组。事实证明,化合物5d的活性是标准抗肿瘤药物5-氟尿嘧啶(5-FU)的五倍,其MG-MID GI 50和TGI值分别为5.05和38.71。最活泼化合物5d的ct-DNA结合研究揭示了强大的相互作用特性。在活性结合位点的分子对接研究为获得的实验生物学数据提供了补充的理论支持。
Four 1,8-naphthalimide derivatives (3a-3d) were designed and synthesized from 1,8-naphthalic anhydride and their structures were characterized by 1H NMR and MS. Their recognition ability to metal ions was then investigated. The results showed the quenching constants (KCV) and binding constants (Ka) values were found in the range of 102-104 M-1, indicating important metal ions recognition abilities of compounds 3a-3d. All the compounds showed recognition of ferric ion, while compounds 3a-3d showed the best recognition ability of silver, cadmium, ferric and ferrous ions, respectively.
