Diapolycopenedioic Acid Xylosyl Esters A, B, and C, Novel Antioxidative Glyco-C sub(30)-carotenoic Acids Produced by a New Marine Bacterium Rubritalea squalenifaciens

Diapolycopenedioic Acid Xylosyl Esters A, B, and C, Novel Antioxidative Glyco-C sub(30)-carotenoic Acids Produced by a New Marine Bacterium Rubritalea squalenifaciens

Novel acyl glyco-carotenoic acids, diapolycopenedioic acid xylosyl esters A, B, and C, were isolated as red pigments by using chromatographic methods from a marine bacterium, Rubritalea squalenifaciens, belonging to subdivision 1 of Verrucomicrobia. The structures of these diapolycopenedioic acid xy...

Zusammenfassung:Novel acyl glyco-carotenoic acids, diapolycopenedioic acid xylosyl esters A, B, and C, were isolated as red pigments by using chromatographic methods from a marine bacterium, Rubritalea squalenifaciens, belonging to subdivision 1 of Verrucomicrobia. The structures of these diapolycopenedioic acid xylosyl esters were determined to be 4-[2-O-acyl-b-D-xylopyranosyl] hydrogen 4,4'- diapo-[psi],[psi]-carotene-4,4'-dioate by spectroscopic analysis. Diapolycopenedioic acid xylosyl ester A showed potent antioxidative activity in a super(1)O sub(2) suppression model.
