摘要:An object of the present invention is to clone a gene which is involved in synthesis of fatty acid having trans-11-, cis-13-conjugated double bonds from fatty acid having a double bone at position Δ12. The present invention provides a gene having any one of the following nucleotide sequences:n (A) a nucleotide sequence encoding an amino acid sequence shown in SEQ ID NO: 1 or 12; (B) a nucleotide sequence encoding an amino acid sequence comprising a deletion, addition or substitution of one or several amino acids with respect to the amino acid sequence shown in SEQ NO: 1 or 12, and having an ability of synthesizing fatty acid having trans-11-, cis-13-conjugated double bonds from fatty acid having a double bond at position Δ12; (C) a nucleotide sequence shown in SEQ ID NO: 2 or 13; (D) a nucleotide sequence comprising a deletion, addition or substitution of one or several nucleotides with respect to the nucleotide sequence shown in SEQ ID NO: 2 or 13, and encoding a protein having an ability of synthesizing fatty acid having trans-11-, cis-13-conjugated double bonds from fatty acid having a double bond at position Δ12; and (E) a nucleotide sequence hybridizing with the nucleotide sequence shown in SEQ ID NO: 2 or 13 or a complementary sequence thereof under stringent conditions, and encoding a protein having an ability of synthesizing fatty acid having trans-11-, cis-13-conjugated double bonds from fatty acid having a double bond at position Δ12.

标题:Synthesis of conjugated fatty acid
发明人：SEIDEL MICHAEL C
摘要:A synthesis process is disclosed for producing a conjugated fatty acid at specified temperature in high yield, including providing an ester of a fatty acid having somewhere in its carbon chain a chain of four carbon atoms such that carbon one bears one hydrogen and one hydroxyl group, carbon two bears two hydrogen atoms, and a double bond is positioned between carbon three and carbon four and reacting with a chloride selected from the group consisting of toluenesulfonyl chloride, methanesulfonyl chloride, benzenesulfonyl chloride, alkylsulfonyl chloride, and arylsulfonyl chloride at a temperature in the range of 10° C.-100° C., preferably 20° C.-50° C. The synthesis process provides a conjugated fatty acid formed from the ester reacted with diazabicycloundecene. In one aspect, the ester is formed in a pyridine solvent. In one aspect, a mesylate is formed with mesyl chloride in acetonitrile and triethyl amine. In one aspect, the reaction with diazabicyclo-undecene is conducted in a polar, non-hydroxylic solvent of acetonitrile to form a preferred isomer at the specified temperature in high yield.

标 题 :Synthesis of conjugated eicosadienoic acid
发明人：SEIDEL MICHAEL C
摘要:A synthesis process for producing 11-cis, 13-trans eicosadienoic acid at room temperature in high yield is disclosed, including providing a tosylate or mesylate of a methyl lesquerolate and 11-cis, 13-trans eicosadienoic acid formed when the tosylate or mesylate reacts with diazabicyclo-undecene. In one aspect, the tosylate of the methyl lesquerolate is formed with tosyl chloride in a pyridine solvent. In one aspect, the mesylate of the methyl lesquerolate is formed with mesyl chloride in acetonitrile and triethyl amine. In one aspect, the tosylate or mesylate is reacted with diazabicyclo-undecene in a polar, non-hydroxylic solvent of acetonitrile to form the preferred isomer of 11-cis, 13-trans eicosadienoic acid at room temperature in high yield.

摘要:The invention provides novel synthetic methodologies for preparing cardiolipin, migrated caridiolipin (1,2-positional isomer of cardiolipin) and their analogues having varying fatty acids and/or alkyl chains with varying length and degrees of saturation/unsaturation. The method comprises (a) reacting an optically pure 1,2-O-dialkyl-sn-glycerol or 1,2-O-dialkyl-sn-glycerol with one or more phosphoramidite reagent(s), wherein a phosphite triester is produced; (b) coupling the product of (a) with glycerol, wherein a protected cardiolipin is produced; and (c) deprotecting the protected cardiolipin, such that cardiolipin is prepared. The cardiolipins and analogues thereof, prepared by the present methods, can be incorporated into liposomes, which can also include active agents such as hydrophobic or hydrophilic drugs, antisense nucleotides or diagnostic agents. Such liposomes can be used to treat diseases or can be used in diagnostic and/or analytical assays.

摘要:A method is described for synthesizing and administering carotenoid compounds with improved antioxidant characteristics. In some embodiments, extension or improvement of conjugation may be employed in structural modification of carotenoids. In other embodiments, reduction of ring/chain steric hindrance may improve the lambda max, and hence, the overall antioxidant capability, of particular compounds. In other embodiments, introduction and/or increase in synthetic handles for conjugation may improve the stoichiometric ratios of conjugating moieties to the polyene backbone. The methods may be used to improve natural and/or synthetic compounds for medicinal application in the treatment of disease.
