Article Abstract
The flagship member of the antiplasmodial isocyanoterpenes, 7,20-diisocyanoadociane (DICA), was synthesized from dehydrocryptone in 10 steps, and in 13 steps from commercially available material. Our previous formal synthesis was reengineered, leveraging only productive transformations to deliver DICA in fewer than half the number of steps of our original effort. Important contributions, in addition to the particularly concise strategy, include a solution to the problem of axial nucleophilic methylation of a late-stage cyclohexanone, and the first selective synthesis and antiplasmodial evaluation of the DICA stereoisomer with both isonitriles equatorial.

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.

Malaria kills more people than any other infectious disease. It claims over 600,000 lives each year. Despite ongoing efforts, an effective scientific endeavor to eradicate it has yet to be realized.

The use of teas made from locally cultivated Artemisia annua to fight malaria in remote areas where access to care is difficult is a matter of debate. This study aimed at document differences in the composition of A. annua teas cultivated in Benin to be sold as antimalarial teas, and in France, and their impact on antiplasmodial activity.

Purpose: Resistance to malaria parasites has overwhelming impacts on the host's antioxidant microenvironment, stimulating oxidative stress during nutrient hunt. Hence, settlers in malaria-ravaged communities have resorted to plant use for fever and malaria due to its availability and affordability. This work assessed the oxidative stress status through antioxidant parameters of sub-fractions of Capsicum frutescens L.

The emergence and spread of artemisinin-partial resistant, malaria-causing provide the impetus for developing novel antimalarials. Pantothenamides are potent inhibitors of malaria parasite proliferation; however, their clinical use is hindered by pantetheinase-mediated degradation in human serum. Here, we report the synthesis and biological activity of a series of pantothenamide-mimics in which the thiazole ring replaces the labile amide bond with various orientations.
