A method for inhibiting and/or ameliorating the occurrence of diseases
associated with reactive oxygen species, reactive nitrogen species,
radicals and/or non-radicals in a subject whereby a subject is
administered a carotenoid analog or derivative, either alone or in
combination with another carotenoid analog or derivative, or
co-antioxidant formulation. The analog or derivative is administered such
that the subject's risk of experiencing diseases associated with reactive
oxygen species, reactive nitrogen species, radicals and/or non-radicals
may be thereby reduced. In some embodiments, the invention may include a
chemical compound including an at least partially water soluble
carotenoid analog or derivative. The carotenoid analog may include a
conjugated polyene with between 7 to 14 double bonds. The conjugated
polyene may include a cyclic ring including at least one substituent. The
substituent may be coupled to the cyclic ring with an ether
functionality.
