||Brevilin A is a strong impetus for the development of selective JAK-STAT inhibitors and therapeutic drugs in order to improve survival of patients with hyperactivated JAKs and STATs. Brevilin A shows antigiardial activity (IC50 = 16.1 μM) and is similarly active in vitro against Entamoeba histolytica (IC50 between 4.5 and 9 μM) and against Plasmodium falciparum (IC50 = 9.42 μM).|

|Antiprotozoal activities of Centipeda minima.[Reference: WebLink]|
METHODS AND RESULTS:
In vitro activity against Giardia intestinalis was used for bioassay-guided fractionation of crude extracts from C. minima. The sesquiterpene lactone, Brevilin A was isolated and found to have antigiardial activity (IC50 = 16.1 μM) and was similarly active in vitro against Entamoeba histolytica (IC50 between 4.5 and 9 μM) and against Plasmodium falciparum (IC50 = 9.42 μM).
Three flavonoids, quercetin, quercetin 3-methyl ether and kaempferol 7-glucosylrhamnoside were also isolated.

||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: firstname.lastname@example.org
||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

|Brevilin A, a novel natural product, inhibits janus kinase activity and blocks STAT3 signaling in cancer cells.[Pubmed: 23704931]|
|Signal abnormalities in human cells usually cause unexpected consequences for individual health. We focus on these kinds of events involved in JAK-STAT signal pathways, especially the ones triggered by aberrant activated STAT3, an oncoprotein which participates in essential processes of cell survival, growth and proliferation in many types of tumors, as well as immune diseases. |
METHODS AND RESULTS:
By establishing a STAT3 signal based high-throughput drug screening system in human lung cancer A549 cells, we have screened a library from natural products which contained purified compounds from medicinal herbs. One compound, named Brevilin A, exhibited both strong STAT3 signal inhibition and STAT3 signal dependent cell growth inhibition. Further investigations revealed that Brevilin A not only inhibits STAT3 signaling but also STAT1 signaling for cytokines induced phosphorylation of STAT3 and STAT1 as well as the expression of their target genes. In addition, we found Brevilin A could attenuate the JAKs activity by blocking the JAKs tyrosine kinase domain JH1. The levels of cytokine induced phosphorylation of STATs and other substrates were dramatically reduced by treatment of Brevilin A. The roles of Brevilin A targeting on JAKs activity indicate that Brevilin A may not only be used as a STAT3 inhibitor but also a compound blocking other JAK-STAT hyperactivation.
Thus, these findings provided a strong impetus for the development of selective JAK-STAT inhibitors and therapeutic drugs in order to improve survival of patients with hyperactivated JAKs and STATs.

|To study the chemical constituents from Centipeda minima.
METHODS AND RESULTS:
The constituents were isolated by column chromatography on silica gel, Sephadex LH-20 and HPLC-ODS, and identified by spectroscopic methods.
Ten compounds, (-)-cis-chrysanthenol-O-beta-D-glucopyranoside (1), methy 3,5-dicaffeoylquinate (2), 3,5-di-O-caffeoyl quinicacid (3), tricin (4), 2-amino-4-methyl-pentanoicacid (5), 2-amino-3-phenyl-propionic acid (6), 4-amino-4-carboxychroman-2-one (7), brevilin-A (8), arnicolide C (9), arnicolide D (10) were isolated and identified.
Compounds 1-7 were isolated from the plant for the first time.
