Description

18β-Glycyrrhetinic acid is the major bioactive component of Glycyrrhiza uralensis and possesses anti-ulcerative, anti-inflammatory and antiproliferative properties.

In Vitro

18β-Glycyrrhetinic acid is the major bioactive component of Glycyrrhizae Radix and possesses anti-ulcerative, anti-inflammatory and antiproliferative properties. MTS assay demonstrates that 24 h treatment of 18β-Glycyrrhetinic acid suppresses cell proliferation in both cell lines in a dose-dependent manner. 18β-Glycyrrhetinic acid at 160 μM significantly decreases the percentage of viable cells to around 40.5±10.5% in A549 and 38.3±4.6% in NCI-H460 (p<0.01 respectively). When the cells are treated with 320 μM 18β-Glycyrrhetinic acid, a greater inhibitory effects on cell proliferation is shown, as the percentage of viable cells is below 30% compare with untreated controls (p<0.001). Treatment with 18β-Glycyrrhetinic acid at 160 μM and 320 μM decreases the levels of full-length PARP and increases the levels of cleaved-PARP^[1].

In Vivo

Rats in 18β-Glycyrrhetinic acid+Triptolide (TP) group which receive low-dose 18β-Glycyrrhetinic acid (50 mg/kg) have significant reductions in the three serum parameters when compare with TP rats. Rats in 18β-Glycyrrhetinic acid+TP group which receive the high-dose 18β-Glycyrrhetinic acid (100 mg/kg) have slightly lowered the levels of three liver enzymes, the reductions do not reach statistical significance compare with TP group. Contrastingly, preadministration of low-dose 18β-Glycyrrhetinic acid protects animals from TP-induced hepatic lesions. On the contrary, low-dose 18β-Glycyrrhetinic acid (50 mg/kg) markedly suppresses the release of the four cytokines above^[3].

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: ≥ 2.17 mg/mL (4.61 mM); Clear solution

This protocol yields a clear solution of ≥ 2.17 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (21.7 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% Corn Oil
Solubility: ≥ 2.17 mg/mL (4.61 mM); Clear solution

This protocol yields a clear solution of ≥ 2.17 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 (21.7 mg/mL) to 900 μL Corn oil, and mix evenly.

Working solution concentration: mg/mL

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.

Cell Assay ^[2]	Primary microglia cultures are used in this study. For treatment assay, microglia are incubated with complete DMEM and stimulated with or without 100 ng/mL IFN-γ in the presence or absence of 18β-Glycyrrhetinic acid (25 μM and 50 μM) at 37°C in a humidified incubator with 5% CO₂. For cell migration assay, the isolated primary microglia that seeded in complete DMEM medium are stimulated with or without IFN-γ (100 ng/mL), and treated with different doses of 18β-Glycyrrhetinic acid, 24 h later, the microglia culture supernatants are collected and added to the lower chambers of Transwell inserts^[2].

Animal Administration ^[3]	Healthy Wistar rats (male, 200±20 g) are used and divided into five groups with 10 individuals for each group randomly. Animals in normal control (NC) group receive distilled water for 6 days and 0.5% CMC-Na for the last 3 days. Rats in Triptolide model group (TP), 18β-Glycyrrhetinic acid low-dose group (GAL+TP), and 18β-Glycyrrhetinic acid high-dose group (GAH+TP) receive distilled water, 18β-Glycyrrhetinic acid (50 mg/kg, p.o., dissolved in distilled water), or 18β-Glycyrrhetinic acid (100 mg/kg, p.o., dissolved in distilled water) for consecutive 6 days, respectively, and liver injury is induced by TP (2.4 mg/kg, p.o., suspended in 0.5% CMC-Na) for the last 3 days. Animals in the above three groups receive TP 6 hours after distilled water or 18β-Glycyrrhetinic acid treatment on the last 3 days^[3].
