Tissue distribution and excretion of radioactively labelled compounds in the Wistar rat after administration of [N-methyl-14C]-erythromycin A
(1987)
Tissue distribution and excretion of radioactively labelled compounds was studied in the Wistar rat after i.v. administration of [N-methyl-14C]-erythromycin A. Whole-body autoradiography and liquid scintillation counting ...
Translactonization in Erythromycins
(1987)
When erythromycin A is heated in diethylamine-acetic acid. an erythromycin hemiketal is obtained, which can be further transformed into a new enol ether and spiroketal. The new euol ether is also obtained in equilibrium ...
Identification of novel erythromycin derivatives in mother liquor concentrates of streptomyces erythraeus
(1987)
The identification of five novel compounds, pseudo-erythromycin A-6,9-hemiketal, 8,9- anhydro-pseudo-erythromycin A-6,9-hemiketal, 8,9-anhydro-pseudo-N-demethylerythromycin A-6,9-hemiketal, 5-0-fl-o-desosaminylerythronolide ...
Optimization of the separation of erythromycin and related substances by high-performance liquid chromatography
(1987)
An improved high-performance liquid chromatographic method for analysis of erythromycin is described. The separation can be performed under mild conditions of pH (6.5) and temperature (35T) on C, and CIS silica-based ...
