生物活性

Pristimerin is a potent and reversible monoacylglycerol lipase (MGL) inhibitor with an IC50 of 93 nM.

体外研究

Pristimerin inhibits the activity of purified MGL with an IC50 of 93±8 nM and that of non-purified MGL (cell lysates of MGL-transfected HeLa cells) with an IC50 of 398±68 nM. Pristimerin inhibits MGL through a mechanism that is rapid, reversible and non-competitive. The binding of pristimerin to MGL might be strengthened by formation of a polar interaction with a regulatory cysteine, possibly Cys. Pristimerin inhibits HFLS-RA and HUVEC cell viability in a dose- and time-dependent manner. Pristimerin decreases VEGF-induced autophosphorylation of VEGFR2 and attenuates the activation of the VEGF-induced VEGFR2-mediated signaling pathway .

体内研究

Pristimerin inhibits inflammation and tumor angiogenesis. Pristimerin significantly reduces vessel density in synovial membrane tissues of inflamed joints and reduces the expression of pro-angiogenic factors in sera, including TNF-α, Ang-1, and MMP-9.

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    90% corn oil

    Solubility: ≥ 2 mg/mL (4.30 mM); Clear solution

    此方案可获得 ≥ 2 mg/mL (4.30 mM,饱和度未知) 的澄清溶液,此方案不适用于实验周期在半个月以上的实验。

    以 1 mL 工作液为例,取 100 μL 20.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。
