The secondary metabolite composition of the gorgonian octocoral Eunicea pinta from San Andrés Island, Colombia, is described for the first time and the structures proposed earlier for several uprolide-type cembranolides need revision and that a minor stereochemical correction is also in order for succinolide.
Bielschowskysin, a gorgonian-derived biologically active diterpene with an unprecedented carbon skeleton.
Bielschowskysin was shown to exhibit antimalarial activity against Plasmodium falciparum as well as strong anticancer activity against two human cancer cell lines.
A novel series of vanadium-sulfite polyoxometalates: synthesis, structural, and physical studies.
Compound 3 comprises a rare example of a non-oxo vanadium(IV) species isolated from aqueous solution and in the presence of the reducing agent SO3(2-), while compound 4 represents a rare examples of an open-framework species isolated at room temperature (20 degrees C).
