Tetraethylthiuram disulfide (Antabuse) inhibits the human malaria parasite Plasmodium falciparum.
Plasmodium falciparum in culture grows optimally at 3% oxygen. Oxygen levels down to 0.5% still support growth, but anaerobic conditions do not. These findings, and the absence of the Krebs cycle in Plasmodium, suggested that in this organism oxygen may not function in electron transport but rather may act through metalloprotein oxygenases. Tetraethylthiuram disulfide (Antabuse, disulfiram) and...
متن کاملThe A/T-specific DNA alkylating agent adozelesin inhibits Plasmodium falciparum growth in vitro and protects mice against Plasmodium chabaudi adami infection.
There is an urgent need for new anti-malarial drugs to combat the resurgence of resistance to current therapies. To exploit the A/T richness of malaria DNA as a potential target for anti-malarial drugs we tested an A/T-specific DNA synthesis inhibitor, adozelesin, for activity against Plasmodium falciparum in vitro and Plasmodium chabaudi adami in mice. Adozelesin is a DNA alkylating agent that...
متن کاملTargeting NAD+ Metabolism in the Human Malaria Parasite Plasmodium falciparum
Nicotinamide adenine dinucleotide (NAD+) is an essential metabolite utilized as a redox cofactor and enzyme substrate in numerous cellular processes. Elevated NAD+ levels have been observed in red blood cells infected with the malaria parasite Plasmodium falciparum, but little is known regarding how the parasite generates NAD+. Here, we employed a mass spectrometry-based metabolomic approach to...
متن کاملClinical Pharmacology of the Antimalarial Artemisinin-Based Combination and other Artemisinins in Children
In 2010, there were estimated 219 million cases of malaria resulting in 666,000 deaths and two-thirds were children. Children are more vulnerable than adults to malaria parasites. In sub-Saharan African countries, maternal malaria is associated with up to 200,000 estimated infant deaths yearly. Malaria is caused by five Plasmodium parasites namely: Plasmodium falciparum, Plasmodium vivax, Plasm...
متن کاملA new model for hemoglobin ingestion and transport by the human malaria parasite Plasmodium falciparum.
The current model for hemoglobin ingestion and transport by intraerythrocytic Plasmodium falciparum malaria parasites shares similarities with endocytosis. However, the model is largely hypothetical, and the mechanisms responsible for the ingestion and transport of host cell hemoglobin to the lysosome-like food vacuole (FV) of the parasite are poorly understood. Because actin dynamics play key ...
