Pretreatment with Eckol (25-100 μg/mL; 2 h) significantly reduces β-hexosaminidase release in IgE/BSA-stimulated BMCMC in a dose-dependent manner[3].
Eckol (25-100 μg/mL; 1 h) inhibits the production of Th2-type cytokines, such as IL-4, IL-5, and IL-13 as well as proinflammatory cytokines, such as IL-6[3].
Eckol (25-100 μg/mL) attenuates cytokine mRNA levels such as IL-1β, IL-4, IL-5, IL-6, IL-13, IFN-γ, and TNF-α in IgE/BSA-stimulated BMCMC[3].
Eckol (25-100 μg/mL; 1 h) inhibits NF-κB activation in IgE/BSA-stimulated BMCMC[3].
Eckol showes a moderate IC50 value (89.5 µM) against the influenza A/Bervig-Mission/1/18 (H1N1) virus[4].

Cell Line:Bone marrow-derived cultured mast cells (BMCMC)
-
Concentration:25, 50 and 100 μg/mL
-
Incubation Time:1 h
-
Result:Inhibited the degradation of IκB-α within the cytosol and the translocation of the NF-κB/p65 subunit into the nucleus that were induced by IgE/BSA.
