Malaria remains a serious worldwide health danger and massive economic trouble to disease-endemic nations. Presently, 250 million of malarial cases are expected worldwide. The emergence of fighting of the Plasmodium parasite against the first-line antimalarial drugs has fueled research attention in the way of designing new scaffolds as well as strategies to counter the drug resistance.

Malaria is a global health problem leading to the death of 435,000 cases in tropical and sub-tropical zones. Spread and emergence of increasing resistance to the antimalarial drugs are the major challenges in the control of malaria. Therefore, searching for alternative antimalarial drugs is urgently needed, and combination treatment preferred as an approach to address this. This study aimed to evaluate in vivo antimalarial activity of zingerone (ZN), and its combination with dihydroartemisinin (DHA) against Plasmodium berghei infected mice.

Salinipostin A (Sal A) is a potent antiplasmodial marine natural product with an undefined mechanism of action. Using a Sal A-derived activity-based probe, we identify its targets in the Plasmodium falciparum parasite. All of the identified proteins contain α/β serine hydrolase domains and several are essential for parasite growth. One of the essential targets displays a high degree of homology to human monoacylglycerol lipase (MAGL) and is able to process lipid esters including a MAGL acylglyceride substrate.

NOT Open Access | Potential antimalarial activity of Coccinia barteri leaf extract and solvent fractions against Plasmodium berghei infected mice

Coccinia barteri (Hook. F.) is traditional used in Southeast of Nigeria in management of fever. This study aimed to evaluate the antimalarial activities of hydro-methanol crude extract and solvent fractions of Coccinia barteri leaf.

Not Open Access | Schistosoma haematobium infection modulates Plasmodium falciparum parasite density and antimalarial antibody responses

Schistosomiasis and malaria are endemic in sub‐Saharan Africa where Schistosoma haematobium (Sh) and Plasmodium falciparum (Pf) coinfections are thus frequent. We explored the effect of Sh infection on antibody responses directed to Pf merozoite antigens and on malaria susceptibility in Beninese children.

NOT Open Access | Multiple-targets Directed Screening of Flavonoid Compounds from Citrus Species to find out Antimalarial Lead with Predicted Mode of Action: An In Silico and Whole Cell-based In vitro Approach

In this study, 44 flavonoids found mainly in the fruit juice of Citrus species having traditional use in malaria-associated fever were selected for in silico multiple-target directed screening against three vital targets of the parasite namely dihydrooroate dehydrogenase (PfDHODH), dihydrofolate reductase thymidine synthase (PfDHFR-TS) and plasma membrane P-type cation translocating ATPase (PfATP4) to find out new lead molecule(s).

Evaluation of Antimalarial Activity of Hydromethanolic Crude Extract and Solvent Fractions of the Leaves of Nuxia congesta R. Br. Ex Fresen (Buddlejaceae) in Plasmodium berghei Infected Mice

In Ethiopia, malaria control has been complicated due to resistance of the parasite and its vectors to the current drugs. Therefore, new drugs are required to avert the problem posed by drug-resistant Plasmodium strains. There is need to investigate alternative sources of antimalarial agents and plants are potential source of antimalarial drugs. This study aimed to investigate the antimalarial activity of the leaves of N. congesta crude extract (hydromethanolic extract) and solvent fractions (n-hexane, chloroform, and aqueous fractions of crude extract) traditionally used to treat malaria in many parts of Ethiopia.

Discovery and development of antimalarial drugs have long been dominated by single-target therapy. Continuous effort has been made to explore and identify different targets in malaria parasite crucial for the malaria treatment. The single-target drug therapy was initially successful, but it was later supplanted by combination therapy with multiple drugs to overcome drug resistance.
