Abstract
Abstract Novel 6-deoxyerythromycin derivatives are disclosed, as are methods for their preparation and use as antiinfective agents. The compounds of the invention include 6-deoxyerythromycins and 6-deoxy-15-norerythromycins which are represented by the structural formula ##STR1## in which R 1 is selected from OH and H, and R 2 and R 3 are independently selected from H and CH 3 , as well as the pharmaceutically acceptable salts and esters of the above compounds. Additionally disclosed are genetically modified microorganisms which produce the compounds of the invention and means for the preparation of those microorganisms.
