生物活性

Madecassoside is a pentacyclic triterpene isolated from Centella asitica (L.), as an anti-inflammatory, anti-oxidative activities and anti-aging agent. [1] In vitro: Madecassoside exhibit significant anti-proliferative and anti-invasive effect in HGF-induced HepG2 and SMMC-77 cells. Madecassoside inhibit the HGF-induced activation of cMET-PKC-ERK1/2-COX-2-PGE2cascade. [1] In vivo: Administration of madecassoside, p.o. , exhibit a direct anti-PF effect in mice. Madecassoside increase the expression of hepatocyte growth factor (HGF) in colon tissues, and HGF receptor antagonists attenuated its anti-PF effect. madecassoside in mice are not mediated by its metabolites or itself after absorption into blood. Instead, madecassoside increases the activity of PPAR-γ, which subsequently increases HGF expression in colonic epithelial cells. [2] The reference for administration is 12 mg/kg. [3]

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

    Solubility: ≥ 2.5 mg/mL (2.56 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (2.56 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。
