In our ongoing search for new pharmacologically active leads from Solomon organisms, we have examined the sponge Theonella swinhoei. Herein we report the isolation and structure elucidation of swinholide A (1) and one new macrolide, swinholide J (2). Swinholide J is an unprecedented asymmetric 44-membered dilactone with an epoxide functionality in half of the molecule. The structural determination was based on extensive interpretation of high-field NMR spectra and HRESIMS data. Swinholide J… Expand

The results indicated that the 14-/15-oxygenated moiety played an important role in the antiproliferative activity and the macrolide derivatives dominated the anti-proliferative effect of the sponge Theonella sp. Expand
Structural insights into Estrogen Related Receptor-β modulation: 4-Methylenesterols from Theonella swinhoei sponge as the first example of marine natural antagonists
The first homology model of active and inactive conformations of the Estrogen Related Receptor β (ERRβ) is reported, benchmarked with the well known agonists gsk4716 and genistein, and the antagonists 4-hydroxytamoxifen and diethylstilbestrol. Expand
Natural Products from the Lithistida: A Review of the Literature since 2000
This review provides an update on the current taxonomic classification of the Lithistida, describes structures and biological activities of 131 new natural products, and discusses highlights from the total syntheses of 16 compounds from marine sponges of the Order lithiumistida providing a compilation of the literature since the last review published in 2002.

4-Methylenesterols from Theonella swinhoei sponge are natural pregnane-X-receptor agonists and farnesoid-X-receptor antagonists that modulate innate immunity
It is demonstrated that swinhosterol B counter-regulates induction of pro-inflammatory cytokines in a PXR-dependent manner and pave the way to development of a dual PX R agonist/FXR antagonist with a robust immunomodulatory activity and endowed with the ability to modulate the expression of bile acid-regulated genes in the liver.
