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. |

Cytotoxic constituents from the skin of the toad Bufo bufo gargarizans.[Pubmed:21279874]
J Asian Nat Prod Res. 2011 Feb;13(2):111-6.
To study the chemical composition of the skin of Bufo bufo gargarizans, various chromatographic methods were used in the isolation procedures and the structures of isolated compounds were determined based on NMR and MS analysis. As a result, two new compounds were isolated from its ethanolic extract and characterized as N-[2-hydroxy-2-(4-hydroxyphenyl)ethyl]-N-methylurea (1) and 19-Oxocinobufotalin 3-adipoylarginine ester (2), together with 11 known compounds. Isolated bufadienolides showed significant inhibition effect against human hepatocellular carcinoma cell line SMMC-7721 in vitro.
