Web1 apr. 2003 · Ionophores are highly lipophilic polyethers that accumulate in cell membranes and catalyze rapid ion movement. When sensitive bacteria counteract futile ion flux with membrane ATPases and transporters, they are eventually de-energized. WebTriorganotins also inhibit the Na + -K + ATPase of cell membranes and the Ca 2+ -translocating ATPase of sarcoplasmic reticulum. Triorganotins are also ionophores which mediate an exchange of Cl -, Br -, SCN - ,I -, or F - ions for OH - ions across biological and artificial phospholipid membranes.
