Synthesis, Characterization, and Acute Cytotoxicity Evaluation of Chloroquine Encapsulating Liposomes

Micro, 2023
Liposomes encapsulating chloroquine were synthesized and characterized. Cryogenic transmission electron microscopy and dynamic light scattering confirmed a liposome size of ~100 nm and uniform shape.

Lack of Evidence for Chloroquine-Resistant Plasmodium falciparum Malaria, Leogane, Haiti

Emerging Infectious Diseases, 2012
Plasmodium falciparum malaria in Haiti is considered chloroquine susceptible, although resistance transporter alleles associated with chloroquine resistance were recently detected.

Chloroquine increases phosphorylation of AMPK and Akt in myotubes

Heliyon, 2016
Aims: There are reports that ataxia telangiectasia mutated (ATM) can activate the AMP-activated protein kinase (AMPK) and also Akt, two kinases that play integral parts in cardioprotection and metabolic function.

Recovery and stable persistence of chloroquine sensitivity in Plasmodium falciparum parasites after its discontinued use in Northern Uganda

Malaria Journal, 2020
Background Usage of chloroquine was discontinued from the treatment of Plasmodium falciparum infection in almost all endemic regions because of global spread of resistant parasites.

Characterization of the commercially-available fluorescent chloroquine-BODIPY conjugate, LynxTag-CQGREEN, as a marker for chloroquine resistance and uptake in a 96-well plate assay. [PDF]

PLoS ONE, 2014
Chloroquine was a cheap, extremely effective drug against Plasmodium falciparum until resistance arose. One approach to reversing resistance is the inhibition of chloroquine efflux from its site of action, the parasite digestive vacuole.

Molecular surveillance of chloroquine-resistant Plasmodium falciparum in sub-Saharan African countries after withdrawal of chloroquine for treatment of uncomplicated malaria: A systematic review

Journal of Infection and Public Health, 2022
Background: A wide spread of chloroquine resistance prompted its discontinued use for treatment of uncomplicated malaria in several African countries. However, disappearances of chloroquine-resistant parasites have been reported in areas with restricted ...

Plasmodium vivax trophozoites insensitive to chloroquine

Malaria Journal, 2008
Background Plasmodium vivax is a major cause of malaria and is still primarily treated with chloroquine. Chloroquine inhibits the polymerization of haem to inert haemozoin. Free haem monomers are thought to catalyze oxidative damage to the Plasmodium spp.

Chloroquine resistant Plasmodium vivax: in vitro characterisation and association with molecular polymorphisms. [PDF]

PLoS ONE, 2007
Treatment failure of chloroquine for P. vivax infections has reached high levels in the eastern provinces of Indonesia, however, in vitro characterization of chloroquine resistance and its associated molecular profile have yet to be determined.Using a ...

Assessment of the activities of Chasmanthera dependens Hochst. combined with other plants on chloroquine-sensitive and chloroquine-resistant Plasmodium berghei

Scientific African, 2022
The prevalence of Plasmodium strains resistant to conventional monotherapy drugs has necessitated the need for more effective and affordable antimalarial agents.

Lack of significant recovery of chloroquine sensitivity in Plasmodium falciparum parasites following discontinuance of chloroquine use in Papua New Guinea

Malaria Journal, 2018
Background Chloroquine treatment for Plasmodium falciparum has been discontinued in almost all endemic regions due to the spread of resistant isolates. Reversal of chloroquine susceptibility after chloroquine discontinuation has been reported in dozens ...
