NAPHTHOQUINONE ANTIMALARIALS

Synthetic Antimalarials

Marine Antimalarials

Malaria is an infectious disease causing at least 1 million deaths per year, and, unfortunately, the chemical entities available to treat malaria are still too limited. In this review we highlight the contribution of marine chemistry in the field of antimalarial research by reporting the most important results obtained until the beginning of 2009, with particular emphasis on recent discoveries....

Drug Antibiotic Interactions-antimalarials

The antimicrobial effects of four antimalarials were determined. The effect of the chosen drugs when combined with a selected number of antibiotics was studied on Staphylococcus aureus and Escherichia coli to determine the types of interaction. Most antimalarials showed either no effect or a synergistic action. However, some exhibited antagonistic effects, which may be either due to some physic...

Antioxidant action of antimalarials.

The effects of antimalarials, chloroquine and quinacrine, on the generation of reactive oxygen species were examined both in polymorphonuclear leucocytes and in the xanthine-xanthine oxidase system. Antimalarials showed inhibitory effects on the production of reactive oxygen species probably by affecting cell functions, such as membrane phospholipid methylation. It is suggested that antimalaria...

Antibodies to 1,2-naphthoquinone.

SUMMARY We have prepared an antibody against 1,2-naphthoquinone. This was accomplished by conjugating the quinone to bovine gamma-globulin. The conjugation product showed a visible light absorption peak of 445 m/u. The globulin-quinone antigen was used to produce rabbit antibodies shown to be specific for 1,2-naphthoquinone. The antibodies could be demonstrated by tanned cell hemagglutination a...
