生物活性

Punicalagin is a polyphenol ingredient isolated from Pomegranate (Punica granatum L.) or the leaves of Terminalia catappa L.. Punicalagin is a reversible and non-competitive 3CLpro inhibitor and inhibits SARS-CoV-2 replication in vitro. Punicalagin is an anti-hepatitis B virus (HBV) agent and has antioxidant, anti-inflammatory, and anticancer effects. Punicalagin has the potential for the research of COVID-19[1][2][3].

体外研究
(In Vitro)

Punicalagin (100 mg/ml) induces apoptosis in HT-29, HCT116 colon cells[1].
Punicalagin slightly inhibits the PLpro activity with an IC50 of over 50 μM. Punicalagin inhibits the plaque formation of SARS-CoV-2 in a dose-dependent manner, with EC50 values of 7.20 μM[4].
Punicalagin binds at an allosteric site in the dimer interface. Punicalagin inhibit SARS-CoV-2 replication by a mechanism other than preventing S-mediated viral entry[4].

体内研究
(In Vivo)

Punicalagin (10 mg/kg) inhibits the edema rate of 58.15% in rats[2].

  • 1.

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

    Solubility: ≥ 2.17 mg/mL (2.00 mM); Clear solution

    此方案可获得 ≥ 2.17 mg/mL (2.00 mM，饱和度未知) 的澄清溶液。

    以 1 mL 工作液为例，取 100 μL 21.7 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。

    将 0.9 g 氯化钠，完全溶解于 100 mL ddH₂O 中，得到澄清透明的生理盐水溶液
