Artemisinin, a natural product isolated from Artemisia annua L., shows a unique anti-cancer activity by an iron dependent mechanism. Artemisinin was covalently conjugated to a transferrin-receptor targeting peptide, HAIYPRH that binds to a cavity on the surface of transferrin receptor. This enables
Targeting the intersubunit cavity of Plasmodium falciparum glutathione reductase by a novel natural inhibitor: computational and experimental evidence.

Glutathione reductase (GR), a homodimeric FAD-dependent disulfide reductase, is essential for redox homeostasis of the malaria parasite Plasmodium falciparum and has been proposed as an antimalarial drug target. In this study we performed a virtual screening against PfGR, using the structures of
An in-silico insight into the substrate binding characteristics of the active site of amorpha-4, 11-diene synthase, a key enzyme in artemisinin biosynthesis.

The enzyme amorphadiene synthase (ADS) conducts the first committed step in the biosynthetic conversion of the substrate farnesyl pyrophosphate (FPP) to artemisinin, which is a highly effective natural product against multidrug-resistant strains of malaria. Due to the either low abundance or low
Isothermal titration calorimetry method for determination of cyclodextrin complexation thermodynamics between artemisinin and naproxen under varying environmental conditions.

A novel isothermal titration calorimetry method was used to determine the complexation thermodynamics for hydroxypropyl-beta-cyclodextrin with artemisinin and naproxen at varying temperature and pH. The new method is very useful for studying complexation reactions between cyclodextrin and drugs with

OBJECTIVE
With the current snags from the use of Artemisinin - combination therapies (ACTs) in malaria treatment in addition to fear of cross- resistance to unrelated drugs, raising the immunocompetence of individuals in malaria endemic areas by vaccination is the best approach to malaria - free
Nuclear magnetic resonance and molecular modeling analysis of the interaction of the antimalarial drugs artelinic acid and artesunic acid with beta-cyclodextrin.
