ovale, the use of primaquine is recommended ( Fernando et al., 2011 Mikolajczak et al., 2015 LalГЁve et al., 2016). For preventing relapse from dormant liver stages after infections with P. Chloroquine accumulates in the parasite's digestive vacuole and interferes with heme-detoxification during hydrolysis of hemoglobin from the host ( Slater, 1993 ThomГ© et al., 2013 WHO, 2015). For a number of decades, chloroquine was used for monotherapy until massive resistance occurred. vivax, Plasmodium ovale, Plasmodium malariae, or Plasmodium knowlesi are equally treated with an artemisinin combination therapy or with chloroquine depending on the sensitivity of the infecting strain. To maintain this highly efficient therapeutic option in view of an increasing number of mutant parasite strains with varying degrees of resistance to the artemisinins ( Jambou et al., 2005), these compounds are combined with drugs that exhibit longer half-lives ( WHO, 2001 Kavishe et al., 2017). The half-life of the fast-acting artemisinins is very short, typically around 1 h. The mechanisms of how artemisinin and its derivatives, such as artesunate and artemether, attain antimalarial activity are thought to reside in generating oxidative stress by liberating reactive oxygen species from an internal peroxo-moiety, and in affecting a calcium ATPase (SERCA or PfATP6) of the sarcoplasmic-endoplasmic reticulum ( Moore et al., 2011). falciparum malaria is an oral artemisinin-based combination therapy ( WHO, 2015). The current first-line treatment of uncomplicated P. Hence, current research aims at identifying suitable epitopes for future immunization programs, and discovery of new drug targets to establish novel modes of antimalarial drug action. Ongoing efforts to eradicate malaria are hampered by the lack of effective antisera and the spreading of resistant strains against antimalarial treatment ( WHO, 2017b). In the subtropical zones outside of Africa, Plasmodium vivax is responsible for up to 64% of the cases. About 90% of the cases occur in the WHO African Region and are caused almost exclusively by the species Plasmodium falciparum. The death toll of malaria is still >400,000 per year. With more than 200 million new infections per year, malaria-causing Plasmodium spp. Human-pathogenic Protozoa, Current Treatment, Resistance Apicomplexa (leishmaniasis), and the amoeba Entamoeba histolytica (amoebiasis). (malaria) and Toxoplasma gondii (toxoplasmosis), with kinetoplastids Trypanosoma brucei (sleeping sickness), Trypanosoma cruzi (Chagas disease), and Leishmania ssp. In this review, we will focus on the progress made on targeting channels and transporters at different levels and the potential for use against infections with apicomplexan parasites mainly Plasmodium spp.

Remarkably, several of the compound hits have been found to inhibit membrane proteins at the periphery of the parasites, i.e., channels and transporters for ions and metabolites.

In recent years, collections of drug-like compounds derived from large-scale phenotypic screenings, such as the malaria or pathogen box, have been made available to researchers free of charge boosting the identification of novel promising targets. Many of the current anti-parasite drugs target soluble enzymes, generate unspecific oxidative stress, or act by an unresolved mechanism within the parasite. Therapeutic options are scarce and massively challenged by the emergence of resistant parasite strains.
