Heavy metal chelator. Reacts with both Zn-proteome and Zn-metallothionein (MT) in LLC-PK1 cells; acts as an intracellular chelator of proteomic Zn2+. Activity decreases intracellular zinc levels, and induces apoptosis in HeLa and cultured human retinal pigment epithelium (RPE) cells. Cell permeable.
