A system and method for authentication of secure products is disclosed. The security feature contains a first component in the form of an emitter capable of emitting light in response to external pump light. The security feature also contains a second component in the form of a taggant that absorbs light in a spectrally narrow range compared to the broader excitation spectrum of the first material. In this manner the emitter and taggant work in combination with one another to create an emission response significantly dependent on the illumination wavelengths and unique to the specific combination of the components. The emitter and taggant can be in the form of a mixture. Further the emitter and taggant may be applied in close proximity to one another, such as within two separate coating layers on a suitable substrate.

The present invention is a mitochondria-targeted antioxidant prodrug useful for the prevention or treatment of diseases or conditions associated with mitochondrial dysfunction resulting from changes in the mitochondrial redox environment. Antioxidant prodrugs of the invention are produced by modifying an antioxidant to a fatty acid so that the resulting prodrug is targeted to and activated by an enzyme of mitochondrial fatty acid beta-oxidation.
