生物活性

Corydaline ((+)-Corydaline), an isoquinoline alkaloid isolated from Corydalis yanhusuo, is an AChE inhibitor with an IC50 of 226 µM. Corydaline is a μ-opioid receptor (Ki of 1.23 µM) agonist and inhibits enterovirus 71 (EV71) replication (IC50 of 25.23 µM). Corydaline has anti-angiogenic, anti-allergic and gastric-emptying and antinociceptive activities.

体外研究

Corydaline (12.5-50 µM; 24 hours) treatment inhibits EV71 replication by suppressing the COX-2 expression and the phosphorylation of JNK MAPK and P38 MAPK but not ERK MAPK in vitro.
Corydaline could inhibit the viral RNA synthesis in a dose dependent manner.

Western Blot Analysis

Cell Line: Vero cells infected with EV71
Concentration: 12.5 µM, 25 µM, 50 µM
Incubation Time: 24 hours
Result: Reduced the phosphorylation of P38 MAPK and JNK MAPK and the expression of COX-2.
体内研究

Corydaline (10 mg/kg; subcutaneous administration; once) treatment shows antinociceptive effects in mice by significantly inhibiting the writhing behavior.

Animal Model: Male CD1 mice (30-35 g, 7-8 weeks old) injected with acetic acid
Dosage: 10 mg/kg
Administration: Subcutaneous administration; once
Result: Showed antinociceptive effects in mice.

In Vivo:

请根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:

——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用; 以下溶剂前显示的百

  • 1.

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% saline

    Solubility: ≥ 2.5 mg/mL (6.77 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (6.77 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 400 μL PEG300 中,混合均匀;向上述体系中加入50 μL Tween-80,混合均匀;然后继续加入 450 μL生理盐水定容至 1 mL。
