The present invention provides compositions and methods for the targeted delivery, release and/or formation of a drug compound at a target site(s) within the body of an individual, such as a diseased and/or inflamed tissue in the body of the individual. These compositions may comprise a halogenated phenol ring cleavably linked to a core structure of a drug compound. Due to the variety of substituents that may be utilized in forming the different types of linkages, numerous examples of drug compounds linked to a halogenated phenol ring are proposed. The present invention further provides compositions comprising halogenated phenol starting compounds that do not undergo cleavage during a dehalogenation reaction to form a drug compound in a targeted tissue when administered to an individual. Methods of administering these non-cleaving compounds are further provided.
