| 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. |

The cytotoxic activity of diterpenoids from Isodon species.[Pubmed:22978208]
Nat Prod Commun. 2012 Aug;7(8):977-8.
Fifteen Isodon diterpenoids (1-15) were evaluated for their cytotoxic activity against HeLa and HL-60 human cancer cell lines, and against murine vincristine (VCR)-resistant P388 cells. Kamebanin (14) showed efficient cytotoxic activity against HeLa and HL-60 cells. In addition, although dihydroenmein (2) and trichorabdal B (7) were inactive against several tested cell types, they were found to have cytotoxic-enhancing activity of VCR against VCR-resistant P388 cells.
The natural diterpenoid kamebanin.[Pubmed:12050429]
Acta Crystallogr C. 2002 Jun;58(Pt 6):o323-4. Epub 2002 May 11.
Kamebanin, alternatively called rel-(-)-(1R,4R,8S,9R,10S,13S,16R)-2,8,16-trihydroxy-5,5,9-trimethyl-14-methylenet etracyclo[11.2.1.0(1,10).0(4,9)]hexadecan-15-one, C(20)H(30)O(4), is a natural diterpenoid which has cytotoxic and antibacterial activity. The molecule is composed of three six-membered rings, which all adopt chair conformations, and one five-membered ring, which adopts an envelope conformation. The conjugated alpha-methylenecyclopentanone ring is the active part in the molecule due to the ring strain. All three hydroxy groups serve as hydrogen-bond donors and acceptors, forming a continuous two-dimensional network.
