Swinholide J, a Potent Cytotoxin from the Marine Sponge Theonella swinhoei
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 determinat...
متن کاملTowards new ligands of nuclear receptors. Discovery of malaitasterol A, an unique bis-secosterol from marine sponge Theonella swinhoei.
Malaitasterol A, an unprecedented bis-secosterol, was isolated from a Solomon collection of Theonella swinhoei. The structure was elucidated on the basis of a combination of comprehensive 1D and 2D NMR analysis, high-resolution mass spectrometry and DFT (13)C chemical shift calculations. The biological characterization of malaitasterol A provided evidence that this compound is a potent agonist ...
متن کاملDraft Genome Sequence of “Candidatus Synechococcus spongiarum” m9, Binned from a Metagenome of South China Sea Sponge Theonella swinhoei
"Candidatus Synechococcus spongiarum" represents the widespread cyanobacterial symbionts found in marine sponges with relatively high genomic variability and likely important ecological roles. We present here the draft genome sequence of "Candidatus Synechococcus spongiarum" m9, which was assembled from a metagenome of Theonella swinhoei sampled in the South China Sea.
متن کاملKoshikamide A2, a cytotoxic linear undecapeptide isolated from a marine sponge of Theonella sp.
Koshikamide A2 (2) was isolated as a cytotoxic metabolite from a marine sponge of Theonella sp. Its structure was elucidated to be a linear undecapeptide by spectroscopic and chemical methods, together with enzymatic conversion to known koshikamide A1 (1). The new peptide moderately inhibited the growth of P388 murine leukemia cells.
متن کامل4-Methylenesterols from a Sponge Theonella swinhoei
Three new 4-methylenesterols, theonellasterol K (1), acetyltheonellasterol (2) and acetyldehydroconicasterol (3), along with two known sterols, theonellasterol (4) and theonellasterone (5), were isolated from the sponge Theonella swinhoei. The structures of these compounds were elucidated on the basis of their spectroscopic data and comparison of the NMR data with those of known analogues. Comp...
