| Bioactivity | Nothofagin, a dihydrochalcone, is isolated from rooibos (Aspalathus linearis)[1]. Nothofagin downregulates NF-κB translocation through blocking calcium influx. Nothofagin has antioxidant activity and ameliorates various inflammatory responses such as the septic response and vascular inflammation[2]. | |||||||||
| Invitro | Nothofagin pre-treatment (0.1, 1, 10 μM) decreases the level of histamine release in RBL-2H3 and RPMCs cells. The production of cytokines are downregulated bynothofagin pre-treatment Nothofagin (TNF-α: 1-10 μM; IL-4: 0.1-10 μM, IL-6: 1-10 μM)[1]. Pre-treatment of DNPHSA-stimulated RBL-2H3 with Nothofagin (10 μM) markedly suppresses the phosphorylation of Lyn, Syk, and Akt[1]. Nothofagin (30 μM; for 6 hours) results in inhibited formation of LPS-induced (100 ng/mL; 4 hours) paracellular gaps with the formation of dense F-actin rings in HUVECs[2]. Nothofagin suppresses IgE-mediated mast cell degranulation both in vitro and in vivo[1]. | |||||||||
