The emergence of chloroquine resistance in Plasmodium falciparum has necessitated the development of alternate strategies for chemotherapy and chemoprophylaxis. One approach has been the identification of drugs that do not possess any intrinsic antimalarial activity when used alone but that potentiate the effect of currently available antimalarial drugs, such as chloroquine. We identified fluox...
We synthesized C-10 substituted triazolyl artemisinins by the Huisgen cycloaddition reaction between dihydroartemisinins (2) and variously substituted 1, 2, 3-triazoles (8a-8h). The antimalarial activities of 32 novel artemisinin derivatives were screened against a chloroquine-resistant parasite. Among them, triazolyl artemisinins with electron-withdrawing groups showed stronger antimalarial ac...
background: malaria remains the world’s most devastating human parasitic infection. our goal was to assess the capacity of increasing concentrations of five antimalarial drugs (fansidartm, halfantm, quinine, coartemtm and chloroquine phosphate) to elicit the generation of methemoglobin in three human erythrocyte genotypes (hb aa, hb as and hb ss). materials and methods: spectrophotometric metho...
The Hartree-Fock method and the 6-31G** basis set were employed to calculate the molecular properties of artemisinin and 20 derivatives with antimalarial activity. Maps of molecular electrostatic potential (MEPs) and molecular docking were used to investigate the interaction between ligands and the receptor (heme). Principal component analysis and hierarchical cluster analysis were employed to ...
The antimalarial activity of some bisbenzylisoquinoline (BBIQ) alkaloids were studied using in vitro culture of both chloroquine (CQ)-sensitive and chloroquine-resistant strains of Plasmodium falciparum. The combination of chloroquine and tetrandrine gave a 44 fold potentiation of malarial killing. Fangchinoline, hernandezine, pycnamine, berbamine and isotetrandrine had similar antimalarial act...
