Polymorphism in plasmodium falciparum drug transporter proteins and reversal of in vitro chloroquine resistance by a 9,10-dihydroethanoanthracene derivative.

چکیده
BG958 reverses resistance in chloroquine-resistant isolates from different countries. Five mutations in the Plasmodium falciparum crt (pfcrt) gene resulting in the amino acid changes K76T, M74I, N75E, A220S, and R371I are systematically identified in resistance-reversed Asian, African, and Brazilian parasites which possess the pfcrt (CIET) haplotype. In combination with BG958, the activity of chloroquine is increased in parasites with the N86Y mutation in pfmdr1.

Dihydroethanoanthracene derivatives as in vitro malarial chloroquine resistance reversal agents.
The ability of four 9,10-dihydroethanoanthracene derivatives (BG920, BG932, BG958, and BG996), as well as verapamil and promethazine, to reverse chloroquine resistance was assessed against 24 chloroquine-resistant and 10 chloroquine-susceptible strains of Plasmodium falciparum from different countries. The 9,10-dihydroethanoanthracene derivatives clearly increase chloroquine susceptibility only...
متن کاملClinical Pharmacology of the Antimalarial Chloroquine in Children and Their Mothers
Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, and Plasmodium knowlesi are the parasites that infect humans. Plasmodium falciparum and Plasmodium vivax cause most of the malarial infections worldwide. Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, and Plasmodium knowlesi are susceptible to chloroquine. Chloroquine was the world's most widely used antim...
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 کاملTreatment of Malaria Parasitaemia in Infants and their Mothers
Malaria is an infection sustained by three parasites namely: Plasmodium falciparum, Plasmodium vivax, and Plasmodium ovale. Plasmodium falciparum is the most common and virulent parasite. These parasites are present in different areas of the sub-Saharan African countries and Asia. In 2010, there were an estimated 219 million cases of malaria resulting in 660,000 deaths and, approximately, two-t...
متن کاملسیر مقاومت داروئی مالاریا در ایران طی سال های 80-1362
One of the main problems in malaria control is the resistance of Plasmodium falciparum to chloroquine and some other antimalarial drugs. This resistance is now quite common in most regions where falciparum malaria is endemic. Between 1968 and 1976, two in-vivo studies were carried out in endemic areas in the south of Iran and they showed P. falciparum to be chloroquine-sensitive. In 1983, the D...
