ionophore

a compound that can increase the permeability of cell membranes to ions. Channel-forming ionophores form pores in the membrane allowing the passage of different ions, whilst mobile carrier ionophores diffuse in the membrane and can be ion-specific.

ionophore

ionophore antibiotic
monocarboxylic polyether antibiotics. They may be monovalent (e.g. monensin, salinomycin) or divalent (e.g. lasolocid). They facilitate transport of ions across biological membranes by forming lipid-soluble complexes with mono or divalent cations; latter day additions to the list include narasin, maduramycin.
