Biological Activity

Anti-inflammatory, antioxidant and free radical scavenger. Inhibits LPS-induced TNF-α, IL-6 and inducible nitric oxide production and blocks NF-κB and AP-1 activation. Also inhibits TNF-α -induced COX-2 expression. Antiproliferative and chemopreventative; inhibits proliferation of Lewis lung carcinoma cells in vivo. Inhibits influenza virus replication in vitro by preventing viral entry. Molecular docking studies also indicate binding to SARS-CoV-2 main protease (Mpro or 3CLpro).

Preparing Stock Solutions

The following data is based on the product molecular weight 286.24. Batch specific molecular weights may vary from batch to batch due to the degree of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
0.5 mM 6.99 mL 34.94 mL 69.87 mL
2.5 mM 1.4 mL 6.99 mL 13.97 mL
5 mM 0.7 mL 3.49 mL 6.99 mL
25 mM 0.14 mL 0.7 mL 1.4 mL
