Epiberberine chloride (Synonyms:表小檗碱氯化物)
目录号 : KM16470 CAS No. : 889665-86-5 纯度 : 98%

Epiberberine chloride 是从黄连中得到的生物碱,为有效的 AChE 和 BChE 抑制剂,和非竞争性的 BACE1 抑制剂,IC50 值分别为 1.07,6.03 和 8.55 μM。Epiberberine chloride 具有抗氧化作用,能够清除 ONOO- (IC50,16.83 μM),可用于阿尔滋海默症和糖尿病的研究。在 3T3-L1 细胞分化早期,Epiberberine 能够下调 Raf/MEK1/2/ERK1/2 和 AMPKα/Akt 信号通路。

生物活性

Epiberberine chloride is an alkaloid isolated from Coptis chinensis, acts as a potent AChE and BChE inhibitor, and a non-competitive BACE1 inhibitor, with IC50s of 1.07, 6.03 and 8.55 μM, respectively. Epiberberine chloride has antioxidant activity, with peroxynitrite ONOO scavenging effect (IC50, 16.83 μM), and may protect against Alzheimer disease. Epiberberine chloride inhibits the early stage of differentiation of 3T3-L1 preadipocytes, downregulates the Raf/MEK1/2/ERK1/2 and AMPKα/Akt pathways. Epiberberine has the potential effect in the research of diabetic disease.

体外研究

Epiberberine (0, 12.5, 25, or 50 μM) dose-dependently inhibits cellular triglyceride accumulation in 3T3-L1 adipocytes, with an IC50 of 52.8 μM.
Epiberberine (12.5-50 μM) suppresses the Raf/MEK1/ERK1/2 and AMPKα/Akt pathways in the early stage of 3T3-L1 adipocyte differentiation.
Epiberberine (0.2, 1, 5 μg/mL) inhibits glucose uptake in HepG2 cells in a concentration-dependent manner.

体内研究

Epiberberine (225 mg/kg, p.o. daily for 40 days) reduces body weight, food consumption, water intake, and urinary output of KK-Ay mice.

    请依序添加每种溶剂: 10% DMSO    90% (20% SBE-β-CD in saline)

    Solubility: ≥ 2.5 mg/mL (6.72 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (6.72 mM,饱和度未知) 的澄清溶液。

    以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液中,混合均匀。
