Assay
Cancer Cell Toxicity
vibi D, E, G and H were analysed using fluorometric microculture cytotoxicity assay using a lymphoma cell line. The IC50 values ranged between 0.96 and 5.0 uM for vibi E, G and H, and vibi D was not cytotoxic at 30 uM. [...]Herrmann A et al. (2008) Phytochemistry 69:939-952
