Lasalocid sodium is a polyether ionophore with potent antibacterial activity. Lasalocid was developed as an animal health product for treatment of coccidia. Lasalocid sodium is able to form neutral complexes with monovalent and divalent cations and transport the ions through apolar phase (including lipid bilayer membranes). Interestingly, lasalocid can also transport larger organic cations, e.g. protonated dopamine.
