Water-soluble derivative of 6-deoxy-tetracyclines

Abstract

This invention relates to a novel water soluble derivatives of 6-deoxy-tetracyclines, particularly of doxycycline, in which a methionine group is linked to the tetracycline group through a methylene bridge, thus obtaining a derivative which is not only water soluble at neutral pH, but also endowed with outstanding properties from the point of view of the therapeutical use.
