In Vitro	Eckol (25-100 μg/mL; 2 h) 预处理以剂量依赖的方式显著降低 IgE/BSA 刺激的 BMCMC 中 β-hexosaminidase 的释放[3]。 Eckol (25-100 μg/mL; 1 h) 抑制 Th2 型细胞因子的产生，如 IL-4、IL-5、 IL-13 以及促炎细胞因子，如 IL-6[3]。 Eckol (25-100 μg/mL) 减弱 IgE/BSA 刺激的 BMCMC 细胞中细胞因子 mRNA 水平，如IL-1β、IL-4、IL-5、IL-6、IL-13、IFN-γ 和 TNF-α[3]。 Eckol (25-100 μg/mL; 1 h) 在 IgE/BSA 刺激的 BMCMC 中抑制 NF-κB 的激活[3]。 Eckol 抑制 influenza A/Bervig-Mission/1/18 (H1N1) 病毒，IC50 为 89.5 µM[4]。 Western Blot Analysis[3] 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.
In Vivo	叶面喷施 Eckol (1 μM) 显著提高了茎长和根长、茎干鲜重、叶面积和叶数[2]。 Eckol (50 or 100 μg/mouse; intradermal; once) 降低被动皮肤过敏反应 (PCA) 诱导小鼠的过敏性炎症反应[3]。 Animal Model: BALB/c mice (8 weeks old), IgE/BSA-induced passive cutaneous anaphylaxis (PCA) model[3] Dosage: 50 or 100 μg/mouse Administration: Intradermal injection, applied on mice ear 2 h prior to anaphylaxis induction Result: Reduced allergic inflammatory responses.
