    Abstract: In the present invention, there are described bromotiacumicin compounds of the general formula I, in which Re1 and Re2 are independently selected from the group consisting of hydrogen and alkanoyl containing 1 to 4 carbon atoms; Re3 and Re4 are selected from the group consisting of (a) Re3 represents hydrogen and Re4 denotes hydroxy, (b) Re3 represents hydroxy and Re4 denotes hydrogen, (c) Re3 and Re4 taken together are =O; or selected from the group consisting of hydrogen and hydroxy; and Re5 and Re6 are independently selected from the group consisting of hydrogen, bromine and chlorine, with the proviso that at least one of Re5 and Re6 must be bromine. Also described are pharmaceutical compositions comprising such compounds, and use of these compounds for the preparation of a medicament intended for treating bacterial infection. Process for preparing the above-described compounds comprises culturing a microorganism belonging to the species dactylosporangium aurantiacum subsp. hamdenensis in a bromide enriched nutrient medium.
