Abstract: High water-soluble erythromycin A derivatives wherein the desosamine moiety is quaternized with an acyloxy-, benzoyloxy- or alkoxycarbonyl-(or carboxy)-acylmethyl iodide, bromine or chloride and esterified in the 2-position with loweralkyl or -(CH2)nCO2R sec , wherein R sec is H, loweralkyl or substituted loweralkyl and n is an integer from 1-5. These new esters readily convert to erythromycin A upon administration to warm-blooded animals.
