专利号:US-7247752-B2 优先权日:2004-10-01 标 题 :Methods for the synthesis of astaxanthin 发明人:LOCKWOOD SAMUEL F; TANG PENG CHO; NADOLSKI GEOFF; JACKSON HENRY L; FANG ZHIQIANG; DU YISHU; YANG MIN; GEISS WILLIAM; WILLIAMS RICHARD; BURDICK DAVID 权利人:CARDAX PHARMACEUTICALS INC 摘要:A method used for synthesizing intermediates for use in the synthesis of carotenoids and carotenoid analogs, and/or carotenoid derivatives. In some embodiments, the invention includes methods for synthesizing optically active intermediates useful for the synthesis of optically active carotenoids. Synthesis of optically active carotenoids, in one embodiment, may be accomplished by forming an optically active dihydroxy intermediate from ketoisopherone. The optically active dihydroxy intermediate may be converted into optically active astaxanthin derivatives.

The carotenoid analog, derivative, or intermediate may be administered to a subject for the inhibition and/or amelioration of any disease that involves production of reactive oxygen species, reactive nitrogen species, radicals and/or non-radicals. In some embodiments, the invention may include methods for synthesizing chemical compounds including an analog or derivative of a carotenoid. Carotenoid analogs or derivatives may include acyclic end groups. In some embodiments, a carotenoid analog or derivative may include at least one substituent. The substituent may enhance the solubility of the carotenoid analog or derivative such that the carotenoid analog or derivative at least partially dissolves in water.
