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. |

About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

New colchicinoids from a native Jordanian meadow saffron, colchicum brachyphyllum: isolation of the first naturally occurring dextrorotatory colchicinoid.[Pubmed:15730238]
J Nat Prod. 2005 Feb;68(2):173-8.
As part of our continuing investigation of Jordanian Colchicum species, the biologically active components of Colchicum brachyphyllum were pursued. Using bioactivity-directed fractionation, nine colchicinoids were isolated and characterized. One of these has a novel ring system, to which we have ascribed the trivial name (+)-demecolcinone (9), and it represents the first naturally occurring dextrorotatory colchicinoid. Another isolated compound was a new colchicinoid analogue, (-)-2,3-didemethyldemecolcine (8), while the remaining seven known colchicinoids were new to the species: (-)-colchicine (1), (-)-3-Demethylcolchicine (2), (-)-cornigerine (3), beta-lumicolchicine (4), (-)-androbiphenyline (5), (-)-demecolcine (6), and (-)-3-demethyldemecolcine (7). The brine shrimp lethality test was used to direct the isolation of these colchicinoids. Moreover, all pure compounds were evaluated for cytotoxicity against a human cancer cell panel, for antimicrobial activity in an array of bacteria and fungi (including yeast), and for their potential to be allosteric modulators of the gamma-aminobutyric acid type A receptor.
