Article Abstract
Malaria is a significant cause of morbidity and mortality, with 263 million cases and 597,000 deaths estimated in 2023. While effective drug combinations are available to prevent and treat malaria, Plasmodium parasite drug resistance is compromising all current options. This situation means that new drugs that act on novel Plasmodium drug targets are needed. Natural products, including artemisinin, derived from Artemisia annua, and its derivatives, have been an important source of antimalarials. In this study we investigated a panel of 43 compounds from the NatureBank natural product library for in vitro activity against asexual stage P. falciparum parasites. Four compounds isolated from Australian plant and marine samples were identified with novel antiplasmodial activity - tambjamine F (IC 1.06 μM) and tambjamine C (IC 3.40 μM) from the marine ascidian Sigillina signifera, bilocularin B (IC 2.18 μM) from the rainforest plant Maytenus bilocularis and hymenialdisine (IC 2.90 μM) from the marine sponge Acanthella costata.

Malaria, a protozoan parasitic disease caused by Plasmodium species, poses significant health risks in endemic regions and contributes to substantial morbidity and mortality. The intricate lifecycle of the parasite, coupled with the emergence of drug-resistant strains, has severely impacted the effectiveness of current anti-malarial treatments. In response, the present study attempts to demonstrate the blood-stage anti-plasmodial action of 30 triazole derivatives designed based on molecular hybridisation technique, and physicochemical properties.

Increased resistance of malaria parasite to first line antimalarial drugs has led to the search for alternatives in the management of malaria. This study evaluated the anti-plasmodial and immunomodulatory effect of dichloromethane plant extract of in infected mice. Chloroquine-resistant infected mice were separated into five treatment groups (200 mg/Kg, 400 mg/Kg, and 600 mg/Kg) with a negative control (given distilled water only) and a positive control (treated with Piperaquine-Dihydro-artemisinin), a standard drug.
