The present invention concerns compounds of the general formula ##STR1## wherein X represents a direct linkage or a linear or branched oxyalkyl group containing one or more carbon atoms, as well as pharmaceutically acceptable salts of such compounds wherein X represents an oxyalkyl group, methods for their preparation by reaction of either piperazine or of its 1,4-bis-hydroxyalkyl derivatives with activated derivatives of acetylsalicylic acid such as halogenides, symmetric or mixed anhydrides, or with a haloalkylester of acetylsalicylic acid, and related pharmaceutical compositions having use as antipyretic, analgesic, anti-inflammatory and anti-histaminic agents.
The present invention describes nanoprodrugs of non-steroidal anti-inflammatory drug (NSAIDs) and nanoprodrugs of α-lipoic acid-containing and NSAIDs. These nanoprodrugs have antioxidant properties and stimuli-responsiveness, which can be used to treat various disease conditions.
