Biological Activity
Description: Kongensin A is an effective heat shock protein 90 (HSP90) inhibitor that has potential anti-necroptosis and anti-inflammation applications.
Targets: HSP (e.g. HSP90)
In vitro:
.Cell Chem Biol. 2016 Feb 18;23(2):257-66.
Natural Product Kongensin A is a Non-Canonical HSP90 Inhibitor that Blocks RIP3-dependent Necroptosis.[Pubmed: 27028885 ]
RIP3-dependent necroptosis has recently garnered significant interest because of the unique signaling mechanisms and pathologic functions involved in this process. Accordingly, a number of chemical screens have identified several effective small-molecule inhibitors that specifically block necroptosis.
METHODS AND RESULTS:
Here, we report the discovery that Kongensin A (KA), a natural product isolated from Croton kongensis, is a potent inhibitor of necroptosis and an inducer of apoptosis. Using a new bioorthogonal ligation method (TQ ligation), we reveal that the direct cellular target of KA is heat shock protein 90 (HSP90). Further studies demonstrate that KA covalently binds to a previously uncharacterized cysteine 420 in the middle domain of HSP90 and dissociates HSP90 from its cochaperone CDC37, which leads to inhibition of RIP3-dependent necroptosis and promotion of apoptosis in multiple cancer cell lines.
CONCLUSIONS:
Collectively, our findings demonstrate that KA is an effective HSP90 inhibitor that has potential anti-necroptosis and anti-inflammation applications.

Source: The herbs of Croton cascarilloides
Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage: 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: service@chemfaces.com

After receiving: 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.
