The inhibitory effects on protein synthesis in vivo of erythromycin base and several erythromycin esters have been determined. An experimental method was used, especially suited for studies on short-lived antibiotics causing low levels of inhibition. Most of the tested derivatives were 23% as active as erythromycin base while a split product of erythromycin, anhydroerythromycin, was 4% as effective.
