    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.

    标题:Regioselective synthesis of 1,3-disubstituted glycerides
    发明人:MAZUR ADAM W; HILER II GEORGE D
    权利人:PROCTER & GAMBLE
    摘要:A process for the selective esterification of glycerol and 1-glyceryl derivatives to 1,3-disubstituted glycerides is disclosed. This process uses a water immiscible solvent, either a hydrocarbon or halogenated hydrocarbon, a 1,3-lipase and fatty acid anhydrides. This reaction mixture selectively esterifies the primary alcohol groups of glycerol or glycerol derivatives. The preferred derivatives of glycerol are alkyl ethers, alkyl phosphates, phospholipids, alkyl and diaklyl phosphates, and sugar glycosides.

    权利人:PPG INDUSTRIES INC
    摘要:Sulfonyl peroxides represented by the formula ##STR1## wherein R and R' independently are alkyl, cycloalkyl, or substituted alkyl or cycloalkyl groups having 1 to 20 carbons, are prepared in a liquid reaction phase by the sulfoxidation of an alkane or cycloalkane reactant with SO 2 and O 2 and acylation of the sulfoxidation product with a carboxylic acid anhydride. In the practice of this invention, an inert, immiscible organic solvent for the sulfonyl peroxide is introduced into the liquid reaction phase to dissolve the peroxide as it is formed and to produce a lower crude product phase containing the sulfonyl peroxide already dissolved in the inert solvent.
