Cited by: 350 Publish Year: 1993 Author: Andrew F.G. While the drug can inhibit certain enzymes, its effect is believed to result, at least in part from its interaction with DNA. Hydroxychloroquine shares the same mechanism of action as chloroquine, but its more tolerable safety profile makes it the preferred drug to treat malaria and autoimmune conditions. While the drug can inhibit certain enzymes, its effect is believed to result, at least in part, from its interaction with DNA. 3. implications chloroquine. As discussed above, glycosylation inhibition might represent a major mechanism for the antiviral effects of chloroquine, suggesting that specific interactions of chloroquine with sugar-modifying enzymes or glycosyltransferases may occur within human cells . To perform this action you need to be signed in to your My CABI account. Chloroquine is very toxic in overdosage; overdosage is extremely hazardous and difficult to treat. Gametocytocide drugs target the parasite during its various sexual stages in the blood,. Malaria is common in areas such as Africa, South America, and Southern Asia.
