Chemical modification of a polyether ionophore antibiotic, cationomycin, was attempted to clarify the structure-activity relationship and to obtain derivatives with higher activity. Deacylcationomycin showed the same ion selectivity as the parent compound, but it was less effective in sodium ion transport and anticoccidial activity. Thirteen acyl or alkyl derivatives were prepared by regioselective reactions. No derivatives were more effective in sodium ion transport. There are apparent relationships between sodium ion transport of acetyl derivatives and their biological activities.
