Product Introduction

Bioactivity

Description	Isoliquiritigenin (ISL) is a flavonoid natural product that inhibits influenza virus replication (EC50=24.7 μM) and aldose reductase activity (IC50=320 nM). Isoliquiritigenin has antitumor activity.
Targets&IC50	HepG2 cells:27.71 μM, influenza virus:24.7 μM (EC50), Hep b3B cells:42.84 ± 2.01 µM, HUVECs:41.17 μM, Aldose reductase:320 nM, SiHa cells:53.8 μM, C2C12 cells:26.34 μg/mL, LO2 cells:> 60 µM, U-373MG cells:68 μM, HeLa cells:58.1 μM, 3T3-L1 cells:96.4 μM, C-33-A cells:32.83 μM, A549 cells:> 20 μM, SK-MEL-28 cells:75 μM, HEK293T cells:3.42 μg/mL
In vitro	METHODS: Normal human hepatocyte cell line LO2 and HCC cell line Hep3B were treated with Isoliquiritigenin (30-60 µM) for 24-72 h. Cell viability was measured by MTT assay. RESULTS: Isoliquiritigenin showed significant cytotoxicity against Hep3B cells with an IC50 of 42.84±2.01 µM at 48 h. This effect was concentration and time dependent. However, at the same Isoliquiritigenin stimulation intensity, the survival of LO2 cells was significantly less affected with an IC50 >60 µM.[1] METHODS: Human colorectal cancer cells HCT-116 were treated with Isoliquiritigenin (20 µM) for 24 h. Apoptosis was detected by Flow cytometry. RESULTS: Treatment of HCT-116 cells with Isoliquiritigenin resulted in a significant increase in apoptosis (17.26%) in the treated group compared to the NC group (7.37%). [2]
In vivo	METHODS: To assay anti-tumor activity in vivo, Isoliquiritigenin (50 mg/kg) was injected intraperitoneally into BALB/c-nu/nu mice bearing Hep3B xenografts once daily for three weeks. RESULTS: Isoliquiritigenin-treated mice had reduced tumor burden in terms of mean tumor size or xenograft weight. [1]
Synonyms	Isoliquiritigen, ISL, GU17

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
