专利号:US-2008221377-A1 优先权日:2006-06-16 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; BRAUN CRISTI L 权利人:LOCKWOOD SAMUEL F; TANG PENG CHO; NADOLSKI GEOFF; JACKSON HENRY L; FANG ZHIQIANG; DU YISHU; YANG MIN; GEISS WILLIAM; WILLIAMS RICHARD; BURDICK DAVID; BRAUN CRISTI L 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.

专利号:US-8796454-B2 优先权日:2012-05-04 标 题 :Synthesis of [2.2.2]-diazabicyclic ring systems 发明人:SCHEERER JONATHAN R 权利人:COLLEGE WILLIAM & MARY 摘要:Herein we describe compositions and methods for the synthesis of [2.2.2]-diazabicyclic structures comprising a domino reaction sequence involving aldol condensation, alkene isomerization, and intramolecular hetero-Diels-Alder cycloaddition. Excellent diastereofacial control during the cycloaddition is enforced with a removable chiral phenyl aminal diketopiperazine substituent. The reaction sequence rapidly generates molecular complexity and is competent with both enolizable and non-enolizable aldehyde substrates. This method provides an efficient route to [2.2.2]-diazabicyclic structures, common to bioactive prenylated indole alkaloids such as the brevianamides and stephacidins.
专利号:US-3790555-A 优先权日:1972-01-20 标 题:Octapeptide derivative of gonadotropinreleasing hormone 发明人:FLOURET G; COLE J 权利人:ABBOTT LAB 摘要:THE SYNTHESIS OF THE OCTAPEPTIDE TRP-SER-TYR-GLY-LEUARG-PRO-GLY-AMIDE CARRYING EASILY REMOVABLE PROTECTIVE GROUPS ON THE SER, TYR, ARG AND TRP MOIETIES IS DESCRIBED. THE NEW SYNTHESIS USES AS THE STARTING MATERIAL TWO TETRAPEPTIDE FRAGMENTS CARRYING EASILY REMOVABLE PROTECTIVE GROUPS. ONE OF THESE FRAGMENTS, TRP-SER-TYR-GLY-OH WITH SUITABLE PROTECTIVE GROUPS, ALSO IS A PART OF THE PRESENT INVENTION. AFTER COUPLING OF THE TWO FRAGMENTS, THE PROTECTIVE GROUP ON THE AMINO-N OF THE TRYPTOPHANE MOIETY IS REMOVED TO OBTAIN AN OCTAPEPTIDE CARRYING EASILY REMOVABLE PROTECTIVE GROUPS WHICH CAN BE RETAINED VHILE BULIDING UP THE MOLECULE TO THE DECAPEPTIDE CHAIN WHICH IS THE GONADOTROPIN-RELEASING HORMONE, AFTER REMOVAL OF THESE PROTECTIVE GROUPS.
