diamino-D-gluco-based GAELs and their analogs, and screened them against a panel of human epithelial cancer cell lines and cancer stem cells. Most of the new GAEL analogs are more potent than chlorambucil, cisplatin and salinomycin. The most potent bisamine-based GAEL analogs 1, 2, 4 and 8 showed 2- to 3-fold enhanced cytotoxicity against various cancer cell lines when compared to β-GLN, indicating that the addition
糖基化抗肿瘤醚脂质(GAEL)是一类通过非凋亡途径杀死癌细胞的两亲性抗肿瘤药。以前的研究已经表明,2-氨基-2-脱氧d -葡萄糖为基础的盖尔如α-GLN和β-GLN显示出大大改善的抗上皮癌细胞的抗肿瘤活性和干细胞。为了进一步优化生物活性,我们制备了一系列二氨基的d -葡糖基础的盖尔和它们的类似物,并筛选它们免受人类上皮癌细胞系和癌症干细胞的一个面板。大多数新的GAEL类似物比苯丁酸氮芥,顺铂和沙利霉素更有效。最有效的基于双胺的GAEL类似物1,与β-GLN相比,图2,图4和图8显示出对各种癌细胞系的细胞毒性提高了2-3倍,这表明添加第二个氨基基团增强了细胞毒性作用。活性最高的GAEL 1和4对分离自乳腺癌(BT-474)和前列腺(DU-145)细胞系的癌症干细胞的影响表明,两种GAEL抑制肿瘤球的形成并导致> 95%的损失5μM时癌症干细胞的活力 GAEL 1对BT-474癌症干细胞的活性优于沙利霉素。
