Ninety samples from the extracts of plants from traditional Chinese medicines were screened for antitumor activity. Paeoniflorigenone (PFG) was isolated as an active ingredient from the root of moutan cortex, which showed the strongest activity. In addition, our data indicated that PFG was cytotoxic and induced apoptosis selectively in the cancer cell lines. These effects were cancelled by the addition of caspase inhibitor Z-VAD-FMK, suggesting that it was mediated by caspase-3 activation.

Renal cell carcinoma (RCC) is among the top ten most common forms of cancer and is the most common malignancy of the kidney. Clear cell renal carcinoma (cc-RCC), the most common type of RCC, is one of the most refractory cancers with an incidence that is on the rise. Screening of plant extracts in search of new anti-cancer agents resulted in the discovery of englerin A, a guaiane sesquiterpene with potent cytotoxicity against renal cancer cells and a small subset of other cancer cells. Though a few cellular targets have been identified for englerin A, it is still not clear what mechanisms account for the cytotoxicity of englerin A in RCC, which occurs at concentrations well below those used to engage the targets previously identified...
