Reversal of chloroquine resistance in Plasmodium falciparum using combinations of chemosensitizers.
Research into chloroquine resistance reversal in Plasmodium falciparum has revealed a widespread range of functionally and structurally diverse chemosensitizers. However, nearly all of these chemosensitizers reverse resistance optimally only at concentrations that are toxic to humans. Verapamil, desipramine, and trifluoperazine were shown to potentiate chloroquine accumulation in a chloroquine-...
متن کاملRESISTANCE OF PLASMODIUM FALCIPARUM TO CHLOROQUINE IN SOUTH EASTERN IRAN
In vivo and in vitro assessments of the response of P. falciparum to chloroquine using WHO standard kits and techniques were carried out in I ran Shahr, Sistan and Baluchestan province of Iran in 1985. In the in vivo assessment, 24 malaria patients treated with chloroquine (25mg/kg over three days) were followed up for one to four weeks. The mean parasite clearance time was 4.3 days and in...
متن کاملPlasmodium falciparum and Plasmodium vivax Demonstrate Contrasting Chloroquine Resistance Reversal Phenotypes
High-grade chloroquine (CQ) resistance has emerged in both Plasmodium falciparum and P. vivax The aim of the present study was to investigate the phenotypic differences of CQ resistance in both of these species and the ability of known CQ resistance reversal agents (CQRRAs) to alter CQ susceptibility. Between April 2015 and April 2016, the potential of verapamil (VP), mibefradil (MF), L703,606 ...
متن کاملReversal of Plasmodium falciparum resistance to chloroquine in Panamanian Aotus monkeys.
An Aotus-Plasmodium falciparum model was used to determine if chloroquine resistance could be reversed in vivo. The putative resistance modulators tested all reverse chloroquine resistance in vitro and included verapamil, chlorpromazine, prochlorperazine, cyproheptadine, ketotifen, a tiapamil analog (Ro 11-2933), and a chlorpromazine analog (SKF 2133-A). Combinations of chloroquine plus chlorpr...
متن کاملOn the Mechanism of Chloroquine Resistance in Plasmodium falciparum
Resistance to chloroquine of malaria strains is known to be associated with a parasite protein named PfCRT, the mutated form of which is able to reduce chloroquine accumulation in the digestive vacuole of the pathogen. Whether the protein mediates extrusion of the drug acting as a channel or as a carrier and which is the protonation state of its chloroquine substrate is the subject of a scienti...
