Valinomycin (NSC 122023), a cyclic depsipeptide antibiotic, act as a potassium selective ionophore. Valinomycin (NSC 122023) inhibits lymphocyte proliferation by its effects on the cell membrane, and induces apoptosis in CHO cells[1]. Valinomycin induces activation of PINK1 leading to Parkin Ser65 phosphorylation[2].
