Flexibilisquinone, a new anti-inflammatory quinone from the cultured soft coral Sinularia flexibilis

Molecules. 2013 Jul 10;18(7):8160-7. doi: 10.3390/molecules18078160.

Abstract

A new quinone derivative, flexibilisquinone (1), was isolated from the cultured soft coral Sinularia flexibilis, originally distributed in the waters of Taiwan. The structure of quinone 1 was established by extensive spectroscopic methods, particularly 1D and 2D NMR experiments. In the in vitro anti-inflammatory effects test, quinone 1 was found to significantly inhibit the accumulation of the pro-inflammatory iNOS and COX-2 proteins of the LPS-stimulated RAW264.7 macrophage cells.
