leukemia (K562), and breast cancer (HMLE), with IC50 between 0.55 and 1.7 μM. The underlying mechanism of 6b against tumor cells is to block autophagic flux, mainly through neutralizing lysosomal acidity. Our results indicated that compound 6b is a potent lysosomal deacidification agent and is accordingly able to block autophagic flux and inhibit tumor cell growth.
合成了一系列12N-取代的槐定胺衍生物,并评估了它们在人HepG2肝癌细胞中的细胞毒活性。构效关系表明,在N'端引入合适的亚芳基或芳基乙基可以大大增强抗扩散能力。其中,具有N'-三甲氧基苯基亚甲基的化合物6b对包括HepG2,白血病(K562)和乳腺癌(HMLE)在内的三种人类肿瘤细胞系表现出有效的抗增殖作用,IC50在0.55至1.7μM之间。6b对抗肿瘤细胞的潜在机制是主要通过中和溶酶体酸性来阻断自噬通量。我们的结果表明,化合物6b是有效的溶酶体脱酸剂,因此能够阻断自噬通量并抑制肿瘤细胞的生长。
