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. Plaquenil sjs Chloroquine ferroquine and ruthenoquine structure Oct 04, 2002 Plasmodium falciparum chloroquine resistance is a major cause of worldwide increases in malaria mortality and morbidity. Recent laboratory and clinical studies have associated chloroquine resistance with point mutations in the gene pfcrt. However, direct proof of a causal relationship has remained elusive and most models have posited a. Due to various difficulties in conducting prospective clinical studies on the prophylactic efficacy of the drug combination, especially in highly chloroquineresistant zones, in vitro drug sensitivity assays and specific molecular markers for chloroquine Plasmodium falciparum chloroquine-resistance transporter, pfcrt and cycloguanil a. B02 inhibited a drug-sensitive P. falciparum strain 3D7 and multidrug-resistant parasite Dd2 in culture, with IC50 values of 8 μM and 3 μM, respectively. We found that B02 is more potent against these P. falciparum strains than against mammalian cell lines. 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 demonstrate that uptake of the antimalarial drug chloroquine is temperature-dependent, saturable, and inhibitable in Plasmodium falciparum. These features are indicative of carrier-mediated transport and suggest that a P. falciparum-encoded protein facilitates chloroquine import. Although both chloroquine-resistant and susceptible parasite isolates exhibit facilitated chloroquine. Inhibitory concentration IC50 of 27 isolates of Plasmodium falciparum collected from Mae Sot, Tak Province to Isoquine, Amodiaquine, Desethylamodiaquine and Chloroquine were found to be ranged from 0.8-9.9 nM, 1.8-14.1 nM, 1.9-11.8 nM, and 6.0-118.4 nM respectively. Resistance to chloroquine CQ in Plasmodium falciparum has a major impact on malaria control worldwide. To gain insight into early parasite stress response, mRNA expression profiles were determined for a set of 10 antioxidant defence genes in synchronized CQ-sensitive 3D7 and CQ-resistant Dd2 clones under transient IC50 CQ-exposure Dd2, 200 nM; 3D7, 14 nM.
