Praeruptorin E

カスタマーレビュー

Based on 1 Customer Validation

Praeruptorin E is an orally active pyranocoumarin compound. Praeruptorin E can be isolated from the dried roots of Peucedanum praeruptorum Dunn. Praeruptorin E reduces the expression of NF-κB. Praeruptorin E upregulates the expression of PXR and CYP3A4. Praeruptorin E inhibits Th2 cytokines, TNF-α, IL6, MPO, and blocks the Ca²⁺ slow channel. Praeruptorin E promotes pulmonary tissue repair and relaxes porcine coronary artery strips. Praeruptorin E protects mice from lipopolysaccharide- and hydrochloric acid-induced acute lung injury. Praeruptorin E can be used in studies related to asthma and acute lung injury.

体外実験

Praeruptorin E (60 μM; 24 h) reduces NF-κB p65 expression and increases PXR and CYP3A4 expression in LPS-induced human L-02 fetal hepatocytes, and this effect is partially dependent on PXR expression^[1].
Praeruptorin E (60 μM) reduces the binding of NF-κB p65 to the PXR gene promoter in human L-02 fetal hepatocytes, as evidenced by a significant decrease in NF-κB enrichment at this region^[1].
Praeruptorin E (4.7 μM) acts as a calcium antagonist on potassium-depolarized swine coronary artery strips with a pD₂' value of 5.2, inhibiting Ca²⁺-induced maximum contraction and shifting the Ca²⁺ concentration-response curve rightward in a non-parallel manner^[3].

体内実験

Praeruptorin E (administered via gavage; once daily for 7 consecutive days at doses of 2.5-40 mg/kg) enhances the anti-asthmatic effect of Aminophylline (HY-B0140) on Ovalbumin (HY-W250978)-induced asthmatic mice by alleviating airway inflammation, mucus secretion and collagen deposition, while also reducing Aminophylline-induced cardiotoxicity, with the 40 mg/kg dose exerting the strongest effect^[1].
Praeruptorin E (20-80 mg/kg; p.o.; single administration 1 hour prior to LPS challenge) dose-dependently attenuates LPS-induced acute lung injury in male BALB/c mice. At the dose of 80 mg/kg, it inhibits neutrophil (PMNs) infiltration by 53%, TNF-α release by 56%, and IL-6 release by 51%, while also suppressing the activation of the NF-κB pathway and ameliorating histopathological changes in lung tissue^[2].
Praeruptorin E (80 mg/kg; p.o.; single administration 1 h prior to hydrochloric acid challenge) protects male BALB/c mice against hydrochloric acid-induced acute lung injury by reducing polymorphonuclear neutrophil (PMNs) infiltration, IL-6 release, protein extravasation and pulmonary histopathological damage^[2].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (5.83 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
