Abstract
A new derivative of the macrolide antibiotic SF-837 substance is manufactured by treating a 9,2'-diacyl- or 9-acyl-SF-837 composition with dimethylsulfoxide and acetic anhydride, and, subsequently, with an alcohol or water-containing solvent to yield the novel compound, 9-Acyl-3'-thiomethoxymethyl-SF-837 composition. In addition to high therapeutic effectiveness and low acute toxicity, this novel compound of the present invention has the great advantages that it does not have the bitter taste originally accompanying the parent compounds, and the further advantage that it is suitable for pediatric and veterinary use.
