| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Two novel sesquiterpene lactones, cytotoxic vernolide-A and -B, from Vernonia cinerea.[Pubmed:12672998]
Chem Pharm Bull (Tokyo). 2003 Apr;51(4):425-6.
Bioassay-directed fractionation of an ethanolic extract of stems of Vernonia cinerea has resulted in the isolation of two novel sesquiterpene lactones, vernolide-A and -B. Their structures were elucidated on the basis of spectroscopic analysis. Biological evaluation showed that vernolide-A demonstrated potent cytotoxicity against human KB, DLD-1, NCI-661, and Hela tumor cell lines (ED(50)=0.02, 0.05, 0.53, 0.04 microg/ml for KB, DLD-1, NCI-661, and Hela, respectively); vernolide-B had marginal cytoxicity (ED(50)=3.78, 5.88, 6.42 microg/ml for KB, NCI-661, and Hela, respectively).
Sesquiterpene lactones with potent cytotoxic activities from Vernonia chinensis.[Pubmed:16254828]
Planta Med. 2005 Oct;71(10):949-54.
Five new sesquiterpene lactones, namely vernchinilides A-E (1-5), along with five known compounds, 8 beta-(2-methylacryloyloxy)hirsutinolide 13-O-acetate (6), 8 alpha-(2-methylacryloyloxy)-1beta,4beta-epoxy-1alpha-methoxy-13-O-acetate-10 betaH-germacra-5 E,7(11)-dien-12,6-olide (7), 8 beta-(2-hydroxymethylacryloyloxy)hirsutinolide 13-O-acetate (8), 8 alpha-tigloyloxyhirsutinolide 13-O-acetate ( 9) and vernolide-B (10) were isolated from Vernonia chinensis. The structures of these new compounds were elucidated on the basis of spectral data, especially 2D-NMR techniques. Compounds 2, 5 and 6 exhibited potent cytotoxic activities against P-388 and A-549 tumor cell lines.
