Overview

Wedelolactone, a compound originally extracted from Eclipta alba, has been shown to inhibit caspase-11, which is a key regulator of proinflammatory cytokine IL-1β maturation and pathological apoptosis. Mechanistic studies suggest that caspase-11 is inhibited by reduction of NF-κB-mediated transcription. Furthermore, this compound has been shown to inhibit IKKγ, a kinase that is crucial for activation of NF-κB, as well as IKK α and IKK β. Weldelolactone also displays potent trypsin inhibition capacities. Additional studies suggest that Wedelolactone contains antagonistic properties towards two PLA2 myotoxins that were isolated from Agkistrodon contortix laticinctus and Crotalus virdis virdis. This agent has also been noted to contain antihepatotoxic behavior consequentially protecting primary cultured liver cells from the toxicity of CC14, Phalloidin, and galactosamine, and inhibit 5-lipoxygenase (5-LO)) activity in porcine leukocytes.
Inhibits caspase-11; a key regulator of proinflammatory cytokine IL-1β maturation and apoptosis.

Note

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 -20°C. Generally, these will be useable for up to one month. 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.
