Drug points: Interaction of thyroxine sodium with antimalarial drugs

Interaction of antimalarial drugs with hemin.

Hemin (ferriprotoporphyrin IX) is shown to form complexes with the chloroquine class of antimalarial drugs. The Soret band of hemin becomes optically active upon the addition of chiral drugs. Results on the hemin-induced quenching of the fluorescence of chloroquine are consistent with the formation of a 2:1 hemin:drug complex with a formation constant of 1.4 x 10(7) at 298 K. Also a direct comp...

Plasmodium falciparum: interaction of shikimate analogues with antimalarial drugs.

The shikimate pathway for aromatic biosynthesis presents a target for antimalarial drug development as this pathway is absent from animals. This study extends previous work on inhibitors of the shikimate pathway, by examining their interaction with the antimalarial drugs pyrimethamine and atovaquone. Combinations of atovaquone with several shikimate analogues exhibited synergistic effects. Thes...

Effectiveness of antimalarial drugs.

Antimalarial drug quality: methods to detect suspect drugs

Malaria continues to be one of the major public health problems in Africa, Asia and Latin America. Plasmodium falciparum malaria is estimated to be the direct cause of 500 million cases and over 1 million deaths per year, mostly in women and children under the age of 5 years [1,2]. In children, progression of disease from mild to severe is particularly rapid [3]. Plasmodium falciparum has becom...
