Fipronil
Based on 1 Customer Validation
Fipronil is a broad-spectrum insecticide effective against Lepidoptera species as well as thrips, locusts, ants, cockroaches, fleas and ticks. Fipronil selectively inhibits GABA receptor with IC50s of 30 nM and 1600 nM for cockroach and rat GABA receptors, respectively. Glutamate-gated chloride channels (GluCls), which are present in cockroaches but not in mammals, are sensitive to the blocking effect of Fipronil. Fipronil also induces apoptosis in HepG2 cells and promotes the expression of CYP1A1 and CYP3A4 mRNA in human hepatocytes.

Fipronil (0.1-25 µM; 72 h) dose-dependently induces expression of CYP1A1 and CYP3A4 mRNA in human hepatocytes[1].
Fipronil (0.1-25 µM; 72 h) induces caspase-3/7 activity in a time- and dose-dependent manner, in HepG2 cells (caspase-3/7 activity is an important marker of the cellular apoptotic process)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Human hepatocytes
-
Concentration:0.1-25 µM
-
Incubation Time:72 h
-
Result:Remarkably increased the expression of CYP1A1 and CYP3A4 mRNA in a dose-dependent manner.
-
Cell Line:HepG2 cells
-
Concentration:0.05, 0.1, 0.5, 1, 3.125, 6.25, 12.5, 25, 50 µM
-
Incubation Time:24, 48, 72 h
-
Result:Exhibited time- and dose-dependent induction of caspase-3/7 activity from 0.1 to 6.25 µM, while slowly decreasing from 12.5 to 50 µM.
Fipronil is more selective for cockroach GABA receptors than for rat GABA[2].
Fipronil blocks cockroach GABA receptors in both resting and activated states, with IC50s of 28 and 35 nM, respectively[2].

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.
