membranes, disrupts ion homeostasis, and thus leads to the induction of apoptosis in cancer cells. It is important to note that the transporter was relatively nontoxic to cells of noncancerous origin. 1c was also shown to induce the deacidification of lysosomes, thereby disrupting autophagy in cancer cells. Taken together, these findings provide a rare example of an artificial ion channel that specifically
已知由合成离子转运蛋白介导的细胞内氯离子浓度波动会通过破坏离子稳态来诱导细胞毒性。然而,这些转运蛋白在调节自噬中的活性在很大程度上仍未得到探索。在这里,我们报告了一种苯甲酰苯甲酰肼 ( 1c ),它自组装形成超分子纳米通道腔,允许氯离子选择性和高效地跨细胞膜转运,破坏离子稳态,从而导致癌细胞凋亡的诱导。重要的是要注意转运蛋白对非癌性来源的细胞相对无毒。1c还显示诱导溶酶体脱酸,从而破坏癌细胞中的自噬。总而言之,这些发现提供了一个罕见的人工离子通道示例,该通道通过破坏自噬诱导细胞凋亡来特异性靶向癌细胞。
