[Abstract]; Chondrocytes are pretreated with Engeletin (10 μM and 20 μM) for two hours, and then TNF-α (20 ng/mL) is added to the culture medium and incubated for another 24 hours. The protein expression levels of collagen II, aggrecan, MMP9 and MMP3 are determined by Western blotting.

Description

IC₅₀ & Target^[1]

NF-κB

In Vitro

Engeletin is a flavanonol glycoside isolated from hymenaea martiana, inhibits NF-κB signaling-pathway activation^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Engeletin (25, 50, 100 mg/kg, i.p.) markedly reduces LPS-increased myeloperoxidase activity in mice, activates NF-κB-pathway activation, decreases the production of inflammatory mediators (iNOS and COX-2), and suppresses the expression of TLR4-signaling downstream molecules such as MyD88, IRAK1, TRAF6, and TAK1 proteins^[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (4.79 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (4.79 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.08 mg/mL (4.79 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 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 (20.8 mg/mL) to 900 μL Corn oil, and mix evenly.

Method for preparing stock solution: mg drug dissolved in μL DMSO (Stock solution concentration: mg/mL).

The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.

If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

Animal Administration
^[1]

Mice^[1]
The mice are classified at random into the following six groups of 10 mice each to cause the endometritis model: blank group, LPS group, Engeletin (25, 50, and 100 mg/kg) + LPS groups, and Engeletin (100 mg/kg) group. Engeletin is solubilized by heated normal saline to give the final concentrations of 25, 50, and 100 mg/kg. Briefly, each uterus is infused with 50 μL of LPS (1 mg/mL) to induce endometritis. At 24 h after the instillation, Engeletin groups receive an intraperitoneal injection of diverse Engeletin concentrations (25, 50, and 100 mg/kg) three times (once every 6 h). The Engeletin group is given an intraperitoneal injection of Engeletin (100 mg/kg). The blank group receive the normal saline. Afterward, the mice are killed by CO₂ inhalation. Uterus tissues are harvested and kept in −80°C^[1].

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
