Desmethylastemizole is a β-hematin (βH) inhibitor and a Histamine H1 receptor antagonist. It exhibits potent antiplasmodium activity against Plasmodium falciparum, with IC50 values of 0.12, 0.11, and 0.06 μM for the Pf3D7, PfDd2, and PfItG strains, respectively. Additionally, Desmethylastemizole effectively blocks hERG K+ channels and inhibits histone-lysine N-methyltransferase EZH2 activity. This compound is relevant for research in long QT syndrome and malaria.
