ß-Carboline-based light and pH dual stimuli-responsive ion transporters induce cancer cell death.

ABSTRACT

Light and pH dual-responsive ion transporters offer better applicability for cancer due to higher tunability and low cytotoxicity. Herein, we demonstrate the development of pH-responsive ß-carboline-based ionophores and photocleavable-linker appended ß-carboline-based proionophores to facilitate the controlled transport of Cl- across membranes, leading to apoptotic and autophagic cancer cell death.
