LPS increases the expression of CD68, iNOS and MPO but decreases the expression of CD206 in murine kidney, while ISL reduces the expression of CD68, iNOS and MPO then increases the expression of CD206 in mice kidney after LPS injection.

The expressions of IκB-α and p-IκB are measured by western blot. The samples are harvested from cells and mice. The results show that ISL could effectively decrease protein levels of p-IκB in HK₂ of the LPS-induced mice but increase IκB-α.

Description

IC₅₀ & Target

IC50: 320 nM (Aldose reductase)

In Vitro

Isoliquiritigenin may prevent diabetic complications through inhibiting rat lens aldose reductase with IC₅₀=320 nM and sorbitol accumulation in human red blood cells with IC₅₀=2.0 μM^[1]. Isoliquiritigenin (100 μM) markedly inhibits the hypoxia-induced prolonged TPS and TR90 of cardiomyocytes. Isoliquiritigenin significantly triggers AMPK Thr172 phosphorylation as compared with vehicle group. Isoliquiritigenin treatment also induces extracellular signal-regulated kinase (ERK) signaling pathway in the cardiomyocytes. Isoliquiritigenin treatment significantly decreases the intracellular ROS levels of isolated cardiomyocytes during hypoxia/reoxygenation^[3]. Isoliquiritigenin not only downregulates IL-6 expression but also significantly decreases levels of phosphorylated ERK and STAT3 and can inhibit phosphorylation levels of ERK and STAT3 induced by recombinant human IL-6, which are critical signaling proteins in IL-6 signaling regulation networks^[4].

In Vivo

Isoliquiritigenin shows concentration-dependent inhibition of the tonic contraction of mouse jejunum induced by various types of stimulants such as CCh (1 mM), KCl (60 mM) and BaCl₂ (0.3 mM) with IC₅₀ values of 4.96±1.97 mM, 4.03±1.34 mM and 3.70±0.58 mM, respectively^[2]. Isoliquiritigenin exhibits significant anti-tumor activity in MM xenograft models and synergistically enhances the anti-myeloma activity of adriamycin^[4].

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.

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.
