Accurate diagnosis of glucose-6-phosphate dehydrogenase (G6PD) deficiency is required to avoid the risk of acute hemolysis associated with 8-aminoquinoline treatment. The performance of the BinaxNOW G6PD test compared with the quantitative spectrophotometric analysis of G6PD activity was assessed in 356 Plasmodium vivax-infected subjects in Brazil, Peru, Thailand, and India. In the quantitative...
During their pathogenic blood stage, malaria parasites invade host erythrocytes where they digest hemoglobin. In the process, they release large quantities of potentially toxic hematin, which they convert to hemozoin. This is an insoluble microcrystalline product. The quinoline antimalarials, such as chloroquine form complexes with hematin and inhibit the formation of synthetic hemozoin (β-hema...
4-Aminoquinolines were hybridized with artemisinin and 1,4-naphthoquinone derivatives via the Ugi-four-component condensation reaction, and their biological activities investigated. The artemisinin-containing compounds 6a-c and its salt 6c-citrate were the most active target compounds in the antiplasmodial assays. However, despite the potent in vitro activities, they also displayed cytotoxicity...
Chagas disease is a neglected tropical disease caused by the flagellated protozoan Trypanosoma cruzi. The current drugs used to treat this disease have limited efficacy and produce severe side effects. Quinolines, nitrogen heterocycle compounds that form complexes with heme, have a broad spectrum of antiprotozoal activity and are a promising class of new compounds for Chagas disease chemotherap...
background: the emergence and spread of chloroquine resistant plasmodium falciparum in the world stimulated some investigators to consider different aspects of chloroquine resistance in human and rodent plasmodia . using animal plasmodia , particularly primate and rodent plasmodia can be useful model for human plasmodia studies. in this study we have tried to consider and compare the sequence ...
Significantly more potent second generation 4-amino-7-chloroquinoline (4,7-ACQ) based inhibitors of the botulinum neurotoxin serotype A (BoNT/A) light chain were synthesized. Introducing an amino group at the C(3) position of the cholate component markedly increased potency (IC50 values for such derivatives ranged from 0.81 to 2.27 μM). Two additional subclasses were prepared: bis(steroidal)-4,...
