Research Abstract |
Nigricanoseides, isolated from the green alga Avrainvillea nigricans, belong to a monogalactosyldiacylglycerol family and exhibit potent growth inhibitory activity against cancer cells. Because of the scarce supply from natural source and the unknown stereochemistry, nigricanosides are not explored biologically in detail. Therefore, studies aiming at the elucidation of their stereochemistry and biological activity have commenced with the partial synthesis of a congener, nigricanoseide A dimethyl ester. As a result, methods for the construction of the two ether linkages have been established, and the stereochemistry of the ether junction between the galactose moiety and the lower acyl chain has been clarified.
