PfDHODH-IN-2, a dihydrothiophenone derivative (Compound 11), is a potent Plasmodium falciparum dihydroorotate dehydrogenase (PfDHODH) inhibitor with an IC50 of 1.11 μM. PfDHODH-IN-2 acts as an antimalarial agent and can be used for the research of malaria.IC50 & Target: IC50: 1.113 μM (PfDHODH)IC50: >50 μM ( hDHODH)In Vitro: Malaria is a global parasitic infectious disease caused by Plasmodium parasites, among which Plasmodium falciparum is the most dangerous one with the highest rates of complications and mortality.PfDHODH-IN-2 shows an overall selectivity for PfDHODH (IC50=1.113 μM) over hDHODH (IC50>50 μM). PfDHODH-IN-2 demonstrats in vitro potency against the 3D7 and Dd2 strains of P. falciparum with IC50 values of both >20 μM, respectively in whole cell assays.
