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.
专利号:US-11220513-B2 优先权日:2015-04-30 标题:Chromium-mediated coupling and application to the synthesis of halichondrins 发明人:KISHI YOSHITO; YAN WUMING; LI JINGWEI; LI ZHANJIE; YAHATA KENZO 权利人:HARVARD COLLEGE 摘要:The present invention provides unified synthesis of the C1-C19 building blocks of halichondrins and analogs thereof using selective coupling of poly-halogenated nucleophiles in chromium-mediated coupling reactions. The present invention also provides a practical and efficient synthesis of C20-C38 building blocks of halichondrins and analogs thereof. Also provided herein are general methods of selective activation and coupling of poly-halogenated analogs with an aldehyde. The provided coupling reactions are selective for halo-enone and halo-acetylenic ketal over vinyl halide and halide attached to a sp hybridized carbon. The provided efficient selective coupling reactions can allow easy access to the C1-C19 building blocks and C20-C38 building blocks of halichondrins and analogs thereof with limited or no purification or separation of the intermediates.
专利号:US-9788548-B2 优先权日:2013-12-13 标题:Synthesis of pure diallyl morpholinium monomers in high yields and using antibacterial effect of their spiro polymers 发明人:BICAK TUGRUL CEM; INCE AHMET; BICAK NIYAZI 权利人:BICAK TUGRUL CEM; Tugrul Cem BICAK 摘要:Herein, the synthesis of N,Ndiallyl morpholinium monomers and polymerization of the same to form rings at high yield and purity are explained. The process involves the synthesis of N,Ndiallyl morpholinium bromide and chloride and subsequently partially or completely exchanging their anions with borate, p-toluenesulfonate, oleate, and acetate anions. The cyclopolimerization of monomers yields water soluble polymers carrying quaternary ammonium groups in each repeated unit, whose aqueous solutions act as a bactericide solution. These solutions are advantageous in preparation of antibacterial formulations intended for domestic use. The polymer with bromide and borate anions is an efficient antibacterial which is able to kill “ Pseudomonas Aeruginosa â€?, the hardest hospital bacterium to cope with, as well as various common bacteria. These formulations are suitable for producing bactericide wet wipes and forming abacterial surfaces and, when combined with air conditioners, generating bacteria free air.
专利号:US-10730904-B2 优先权日:2012-11-14 标 题:Method for liquid-phase synthesis of nucleic acid 发明人:NONOGAWA MITSURU; NAGATA TOSHIAKI; SAITO HIDEKI; YASUMA TSUNEO 权利人:TAKEDA PHARMACEUTICALS CO 摘要:In this method, an oligonucleotide represented by formula (II) [wherein Y 1 , Q, Base, r and r′ are each as defined in claim 1 ] is prepared by using, as a synthesis unit, a novel nucleoside monomer compound represented by formula (I) [wherein X, R 1 , Y, Base, Z, Ar, R 2 , R 3 and n are each as defined in claim 1 ]. The novel nucleoside monomer compound is a nucleoside, the base moiety of which is substituted with an aromatic-hydrocarbon-ring-carbonyl or -thiocarbonyl group having at least one hydrophobic group. The method can dispense with column-chromatographic purification in every reaction, and enables base elongation not only in the 3′-direction but also in the 5′-direction, thus attaining efficient liquid-phase mass synthesis of an oligonucleotide.

专利号:US-7435861-B2 优先权日:2005-04-29 标 题 :Methods for synthesis of carotenoids, including analogs, derivatives, and synthetic and biological intermediates 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 for synthesizing intermediates for use in the synthesis of carotenoid synthetic intermediates, carotenoid analogs, and/or carotenoid 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.
