常见问题列表

生物活性
Nothofagin 是一种二氢查尔酮,是从如意宝 (Aspalathus linearis) 中分离得到的。Nothofagin 通过阻断钙 (calcium) 内流来下调 NF-κB 的转运。Nothofagin 具有抗氧化活性,可改善各种炎症反应,例如脓毒症反应和血管炎症。
体外研究

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).
Pre-treatment of DNPHSA-stimulated RBL-2H3 with Nothofagin (10 μM) markedly suppresses the phosphorylation of Lyn, Syk, and Akt.
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.
Nothofagin suppresses IgE-mediated mast cell degranulation both in vitro and in vivo.

体内研究

Nothofagin (1 mg/kg; orally; once a day; for 7 days) significantly increases the urinary volume of both normotensive (NTR) and spontaneously hypertensive rats (SHR).

Animal Model: Male Wistar normotensive and spontaneously hypertensive rats (3-4 months old)
Dosage: 1 mg/kg
Administration: Orally; once a day; for 7 days
Result: Significantly increased the urinary volume of both NTR and SHR.
