Aucubin 是一种可从许多传统的草药中提取的环烯醚萜苷。Aucubin 具有许多生物学活性，例如抗氧化，抗衰老，抗炎，抗菌，抗纤维化，抗癌，保肝，神经保护和骨保护作用。
| 生物活性 | Aucubin, an iridoid glucoside, is isolated fromPlantago asiatica,Eucommia ulmoides, the leaves of Aucuba japonica and more recently from butterfly larva. Aucubin has many biological activities, such as antioxidant,anti-aging, anti-inflammatory, antimicrobial, anti-fibrotic, anti-cancer, hepatoprotective, neuroprotective and osteoprotective effects[1][2][3]. |
体外研究
(In Vitro) | Aucubin (0.001-1 μg/mL; pretreated for 30 min) dose-dependently inhibits IgE-induced TNF-α and IL-6 production and expression in RBL-2H3 cells, with IC50s of 0.101 and 0.19 μg/mL, respectively[2].
Aucubin (0.01 μg/mL; pretreated for 30 min) inhibits IgE-induced nuclear translocation of p65 subunit of NF-κB and degradation of IκBα in RBL-2H3 cells[2].
Aucubin (0.001-1 mM; 12 h) increases PC12 cellular viability and markedly inhbits H2O2-induced apoptotic cell death[4].

体内研究
(In Vivo) | Aucubin (5 mg/kg; i.p. for 15 d) has antioxidant and pancreas-protective effects on rats with streptozotocin-induced diabetes[1].
Aucubin (40-200 mg/kg; a single i.p.) exhibits significant protective activity against α-amanitin intoxication in mice[5].
Aucubin (5 mg/kg/day; i.p. for 21 d) decreases the breathing frequency, increases the lung dynamic compliance, alleviates lung parenchymal fibrotic changes, and reduces the intrapulmonary collagen disposition and inflammatory injury of BLM-stimulated mice[6].
| Animal Model: | Male Wistar rats (200-230 g) induced diabetes by a injection of streptozotocin[1] | | Dosage: | 5 mg/kg | | Administration: | I.p. twice daily for the first 5 days, followed by single injections daily for the last 10 days | | Result: | Increased the body weight of streptozotocin-diabetic rats.
Lowered the blood glucose level.
Decreased the level of lipid peroxidation and increased the activities of antioxidant enzymes.
Increased in insulin immunoreactivity and the number of immunoreactive β cells compared with untreated diabetic rats. |
