Flumethrin
Based on 1 Customer Validation
Flumethrin (FCR 2769) is a pyrethroid insecticide and acaricide. Flumethrin targets voltage-gated sodium channels and estrogen receptor α (ERα). Flumethrin induces cytotoxicity, apoptosis, genotoxicity and DNA damage in breast cancer cells by regulating the expression of BCL2, BAX, TP53 and P21 genes. Flumethrin is applicable to relevant studies on ectoparasite infections (tick and flea burdens) in dogs and cats, as well as breast cancer.

Biological Activity
Flumethrin (10 μM) binds preferentially to the open state of voltage-gated Na+ channels in isolated Spodoptera frugiperda neuronal cells, preventing channel closure only after channel activation by current pulses[1].
Flumethrin (0.000064-5 μg/cm2; 24 h; 48 h), applied as a surface coating, dose-dependently kills adult Ctenocephalides felis fleas in vitro, with 100% mortality achieved at ≥1 μg/cm2 by 48 h and an ED50 of 0.039 μg/cm2 for 48 h mortality[1].
Flumethrin (0.0001-10 μM; 144 h) acts as a partial to full estrogen agonist in MCF-7 human breast carcinoma cells, inducing proliferation with relative proliferative effects of 77% at 0.1 μM and 80% at 1 μM compared to 17β-estradiol[2].
Flumethrin (0.1 μM) upregulates estrogen-responsive genes TFF1, ESR1, and PGR in MCF-7 human breast carcinoma cells, confirming estrogenic activity[2].
Flumethrin (0.1-2000 μM; 24 h) reduces viability of MCF-7 human breast carcinoma cells with an IC50 of 1671 μM after 24 h incubation, and induces significant concentration-dependent cytotoxicity at concentrations of 100 μM and higher[2].
Flumethrin (1-2000 μM; 24 h) induces significant lipid peroxidation in MCF-7 human breast carcinoma cells at concentrations of 1000 μM and higher after 24 h incubation[2].
Flumethrin (1-1000 μM; 24 h) induces concentration-dependent apoptosis in MCF-7 human breast carcinoma cells, with significant increases in late apoptotic cells at 100 μM and 1000 μM after 24 h incubation[2].
Flumethrin (1000 μM; 24 h) induces apoptosis in MCF-7 human breast carcinoma cells via a mitochondrial pathway, upregulating BAX, TP53, and p21CDKN1A and downregulating BCL2 mRNA expression after 24 h incubation[2].
Flumethrin (1-1000 μM; 24 h) induces significant genotoxicity in MCF-7 human breast carcinoma cells at all tested concentrations (1, 10, 100, 1000 μM) after 24 h incubation, increasing MN, NBUD, and NPB frequencies without altering nuclear division index[2].
Flumethrin (1-1000 μM; 24 h) induces significant DNA strand breaks in MCF-7 human breast carcinoma cells at concentrations of 10 μM and higher after 24 h incubation, as measured by increased Olive tail moment, tail moment, tail % DNA, and tail length in the comet assay[2].
