| 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. |

Precise discovery of a STAT3 inhibitor from Eupatorium lindleyanum and evaluation of its activity of anti-triple-negative breast cancer.[Pubmed:29086600]
Nat Prod Res. 2017 Oct 31:1-9.
Michael reaction acceptors (MRAs) are a class of active compounds. There is a great prospect to screen STAT3 inhibitors from Eupatorium lindleyanum, furthermore, to discover lead compounds for anti-triple-negative breast cancer (TNBC). In this study, glutathione (GSH) was employed, and a UPLC-MS screening method was developed to discover MRAs. We screened MRAs which can inhibit STAT3 using a STAT3-dependent reporter system. Six sesquiterpene lactones, including a new compound Eupalinolide O (1), together with five known compounds, Eupalinolide I (2), Eupalinolide K (3), Eupalinolide H (4), Eupalinolide J (5) and Eupalinolide G (6) were isolated. Eupalinolide J was identified as MRA that decreased luciferase activity of STAT3. Preliminary activity assessment showed that Eupalinolide J could inhibit the viability of TNBC cell lines. We demonstrated that Eupalinolide J, which is a natural typical MRA, has a notable inhibition of STAT3 activity and a potential cytotoxic activity against TNBC cell lines.
