Antimalarial potential of Kerala Ayurvedic Water "Pathimugam".

Background Objectives: The persistent threat of drug resistant malaria demands new cures. Low prevalence of malaria in the Indian state of Kerala compared with other proximal states led us to explore if there is any traditional practice in Kerala which may confer protection against malaria. In this context, our attention was drawn to "Pathimugam" i.

Novel quinolinepiperazinyl-aryltetrazoles targeting the blood stage of .

The emergence of drug resistance against the frontline antimalarials is a major challenge in the treatment of malaria. In view of emerging reports on drug-resistant strains of against artemisinin combination therapy, a dire need is felt for the discovery of novel compounds acting against novel targets in the parasite. In this study, we identified a novel series of quinolinepiperazinyl-aryltetrazoles (QPTs) targeting the blood stage of .

Identification of Novel, Potent, and Selective Compounds against Malaria Using Glideosomal-Associated Protein 50 as a Drug Target.

Phylum apicomplexan consists of parasites, such as and . These obligate intracellular parasites enter host cells an energy-dependent process using specialized machinery, called the glideosome. In the present study, we used GAP50, a glideosome-associated protein, as a target to screen 951 different compounds from diverse chemical libraries.

Annickia affinis (Exell) Versteegh & Sosef methanol stem bark extract, potent fractions and isolated Berberine alkaloid target both blood and liver stages of malaria parasites.

Ethnopharmacological Relevance: Having identified Annickia affinis as the most potent antiplasmodial plant constituent in a hepta-herbal Agbo-iba (HHA) formula commonly used to manage malaria in Benin city, Nigeria, we have in this study attempted to identify the specialized metabolites responsible for antiplasmodial activity of A. affinis through anti-blood stage malaria parasite activity guided isolation of potent molecules from its stem bark methanol extract. After that, phenotypic effects, including stage-specific kill kinetics, were investigated.
