Methods for treating eye diseases associated with inflammation and / or vascular proliferation in subjects are disclosed. The methods include administering therapeutically effective amounts of a tranilast compound, in particular (E)-2-[[3-(3-Methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid or (E)-2-[[3,4-Bis(difluoromethoxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid or pharmaceutically acceptable salts or solvates thereof.
acid anhydride is postulated to be the active intermediate responsible for this successful amidation. This direct amidation is an atom- and step-economical reaction. A novel and facile boric acid catalyzed direct amidation between amino-azaarene compounds and carboxylicacids has been developed. The amidation proceeded cleanly and provided good to excellent yields of the desired amides. Boric acid
