It is reported that transmembrane anion/cation symport can induce cell death by disrupting the ionic homeostasis of cells. Herein,we designed and synthesized aza-crown ether-squaramide conjugates and studied their anion/cation symport properties and anti-tumor activity(Fig.1).The results indicate that these conjugates exhibit potent liposomal and in vitro anion/cation symport,and are able to trigger cell apoptosis by modifying the intracellular pH,inducing the basification of acidic organelles in live cells and facilitating the influx of chloride and sodium ions into cells.
