Ethalfluralin
Ethalfluralin is a dinitroaniline herbicide and microtubule inhibitor. Ethalfluralin blocks nuclear division and cytokinesis of parasites by inhibiting intranuclear spindle formation. Ethalfluralin activates the phosphorylation levels of NF-κB and P38 MAPK, inhibits the PI3K/AKT signaling pathway, impairs mitochondrial function, and induces apoptosis, endoplasmic reticulum stress, autophagy, and ROS production. Ethalfluralin is applicable to research related to toxoplasmosis.

Ethalfluralin (1 μM; 0-24 h) acts for up to 24 h but does not inhibit nucleic acid synthesis of tachyzoites of the Toxoplasma gondii RH strain in primary human foreskin fibroblasts, even though it completely abolishes parasite activity[3].
Ethalfluralin (1 μM; 20 h) blocks nuclear division of tachyzoites of the Toxoplasma gondii RH strain in primary human foreskin fibroblasts by inhibiting intranuclear spindle formation, while preserving their subpellicular microtubules and causing expansion of the endomembrane compartment[3].
Ethalfluralin (1 μM) inhibits the release of tachyzoites of Toxoplasma gondii RH strain induced by calcium ionophores in primary human foreskin fibroblasts, and simultaneously causes shrinkage of the vacuolar space and increased refractivity of treated parasites after ionophore treatment[3].
