Halofantrine
Based on 2 publication(s) in Google Scholar
Halofantrine (SKF-102886 hydrochloride; WR-171669 hydrochloride) is a blocker that delays the delayed rectifier potassium current by inhibiting human ERG channels, and it is a potent antimalarial agent with oral activity. Halofantrine inhibits the Cap1-dependent oxidative stress response of Candida albicans, suppresses ROS responses, and enhances the antifungal (Fungal) activity of oxidative damage agents. Halofantrine exhibits antifungal activity in the Galleria mellonella model, and shows antimalarial activity against Plasmodium strains both in vitro and in animal models. Halofantrine can be used in studies related to invasive candidiasis, falciparum malaria, and vivax malaria.

Halofantrine (24-48 h) acts synergistically with oxidative damage agents Plumbagin (HY-N1497), menadione, and H2O2 against Candida albicans strains SC5314 and SN152, with FICI values of 0.0938, 0.1563, and 0.2526, respectively[1].
The combination of halofantrine (24 h) and H2O2 retains synergistic activity against Candida albicans hog1Δ/Δ and rad53Δ/Δ strains (with FICI values of 0.5 and 0.2813, respectively), but shows no synergistic activity against cap1Δ/Δ, ybp1Δ/Δ or gpx3Δ/Δ strains when combined with H2O2, indicating that its oxidative stress inhibitory effect depends on the Cap1-Ybp1 pathway[1].
Halofantrine inhibits chloroquine (HY-17589A)-sensitive Plasmodium falciparum in vitro, with an IC50 value of 1.5-2.5 μg/L[2].
Halofantrine (1.3-3.9 μg/L) inhibits chloroquine-resistant Plasmodium falciparum in vitro, with an IC50 value of 1.3-3.9 μg/L[2].
Halofantrine (10 μM) inhibits glucose-dependent proton efflux in Plasmodium berghei-infected mouse erythrocytes at a concentration of 10 μmol/L in vitro[2].
Halofantrine inhibits Plasmodium falciparum in vitro, with an ID50 of 4.0 μg/L[2].
