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. Chloroquine dosage lupus Chloroquine side effects treatment Hydroxychloroquine tablets ip 400 mg Chloroquine, like other intercalators, may work by altering three-dimensional structure. For exam- ple, there is evidence that DNA may form left-handed helices Z-DNAin transcriptionally active regions. We have found that chloroquine prevents the transition of DNA to the Z form in vitro, at concentrations as low as 20 Ref. 17. Oct 01, 2018 Mechanism of Action Chloroquine, a 4-aminoquinoline, is an anti-protozoal agent. The precise mechanism by which Chloroquine exhibits activity is not known. Chloroquine, may exert its effect against Plasmodium species by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme. Also, a concentration-dependent inhibition of chloroquine was obtained with prodigiosin-treated DNA. Chloroquine is an intercalating agent that unwinds DNA, resulting in a decrease in negative superhelicity and thus in the negative superhelical free energy activity. 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.

Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. Chloroquine - Wikipedia.

Clinical trials investigating the safety/efficacy of chloroquine or hydroxychloroquine monotherapy or combination therapy. Investigative agents Conditions Trial ID number Phase Location Status Ref. In our study, we used an intercalating drug, chloroquine, which is known to decrease the twist of the double helix and thus altered the conformation of the whole DNA. During our experiments, a chloroquine solution was added while imaging a few highly condensed plasmid nanoparticles in solution.
