The in vitro cytotoxicity of bipinnatins 4, 6, and 7 against the NCI tumor cells MCF breast cancer, NCI-H460 non-small cell lung cancer, and SF-268 CNS cancer was evaluated and only bipinnatin Q displayed significant cytotoxic activity.
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).
