Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it. Can plaquenil cause alopecia Hydroxychloroquine breastfeeding The mode of action of chloroquine is still controversial. Proposed mechanisms of action include 1 DNA intercalation, 2 lysosome accumulation and 3 binding to ferriprotoporphyrin IX. Recent data suggest that intercalation into parasite DNA can occur at physiological concentrations of the drug. Title Nucleus may be the key site of chloroquine antimalarial action and resistance development. Abstract The first proposed hypothesis about the mechanism of chloroquine CQ action on malaria parasites is DNA intercalation hypothesis which indicates that the site of CQ action is within the nucleus. Apr 02, 2019 While the drug can inhibit certain enzymes, its effect is believed to result, at least in part, from its interaction with DNA. However, the mechanism of plasmodicidal action of chloroquine is not completely certain. Activity in vitro and in vivo. Chloroquine is active against the erythrocytic forms of Plasmodium vivax. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

We have reported data on the antitumor action of complexes 1 and 5 against colon and liposarcoma cell lines 42 and in this paper we disclose new results concerning other tumor cells.

Possible results of the assay Substrate Compound a Relaxed DNA Compound is an intercalator but not a topo I inhibitor. The intercalation leads to a decreased twist and a consequent increased writhe positive supercoils. The topo I relaxes the DNA so writhe becomes zero. Chloroquine enters the red blood cell by simple diffusion, inhibiting the parasite cell and digestive vacuole. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion. Chloroquine diphosphate is a 4-aminoquinoline anti-malarial and anti-rheumatoid agent, also acting as an ATM activator. Chloroquine is a chemotherapeutic agent for the clinical treatment of malaria. Chloroquine is able to bind to DNA, and inhibit DNA replication and RNA synthesis which in turn results in cell death.
