Abstract

The present invention provides novel compounds and pharmaceutical compositions for the prevention and/or treatment of cancer and precancerous conditions thereof, for the treatment of pain and fever, for the treatment of skin disorders, and for treating and/or preventing inflammation-related diseases and/or cardiovascular diseases. The compounds of the invention also have analgesic properties and anti-platelet properties. The compounds of the invention may be provided to animals, including mammals and humans, by administering a suitable pharmaceutical dose in a suitable pharmaceutical dosage form. The compounds of the invention have improved efficacy and safety, including higher potency and/or fewer or less severe side effects, than conventional therapies. The compounds of the invention comprise a biologically active moiety or portion (A) that has, or is modified to have at least one carboxyl group. The moiety A is preferably an aliphatic, aromatic or alkylaryl group, preferably derived from a non-steroidal anti-inflammatory drug or NSAID (A). The moiety A is bound to a linker moiety (B) via the carboxyl of group A and a linking atom that is selected from oxygen, nitrogen, and sulphur, to form a carboxylic ester, and amide, or a thioester, bond (X¹) between groups A and B. Moiety B is a single bond, an aliphatic group, a substituted benzene, or an alkylene substituted hydrocarbon chain, which in turn is bound to functional moiety Z, which facilitates access of the compound into cells. The moiety Z can comprise, for example, a phosphorous-containing group, a nitrogen-containing group, or a folic acid residue.
