    The ubiquitin/proteasome system plays a major role in overall protein turnover, especially in fast dividing eukaryotic cells including plasmodia. Previous studies show that the 20S proteasome is expressed and catalytically active in plasmodia and treatment with proteasome inhibitors arrests parasite growth.

    Drug sensitivity of progeny. The progeny were placed into two groups depending on whether they had the HB3 or 3D7‐like genotype at the pfmdr1 locus. There was a clear allelic association between possession of the HB3‐like pfmdr1 genotype and increased sensitivity to mefloquine, halofantrine, lumefantrine, artemisinin, artemether and arteflene. K1 chloroquine-resistant and 3D7 chloroquine-sensitive reference strains were used as controls. Results Growth profile of all field isolates was identical to that of reference parasites. The IC50 values of all the drugs were also similar against field isolates and reference parasite strains, except K1, exhibited high IC50 value 275±12.5.

    Epoxomicin, YU101, YU102, MG132, MG115, Z-L), gliotoxin, PR11 and PR39 were tested and compared to chloroquine- and artesunate-activities in a standardized in vitro drug susceptibility assay against P. Freshly obtained field isolates from Lambaréné, Gabon, were used to measure the activity of chloroquine, artesunate, epoxomicin, MG132, lactacystin and bortezomib. This is the first comprehensive screening of proteasome inhibitors with different chemical modes of action against laboratory strains of P. Subsequently, a selection of inhibitors was tested in field isolates from Lambaréné, Gabon.

  6. Whereas the IC50 and IC90 values of compounds which exhibited in vivo suppressive activity in mice ranged between 10 and 307 nm and 61 and 965 nM, respectively, against 3D7 and 75 and 806 nm and 241 and 1232 nM against the K1 strain of P. falciparum.

    There was nearly a two-fold decrease in the IC50 value determined for chloroquine in this study compared to that determined in 2004 57.56 nM. This observation is important, since it suggests a significant improvement in the efficacy of chloroquine, probably as a direct consequence of reduced drug pressure after cessation of its use. The naturally occurring benzoquinone ansamycin compound, geldanamycin GA, is a specific inhibitor of heat shock protein 90 Hsp90 and is a potential anticancer agent. Since Plasmodium falciparum has been reported to have an Hsp90 ortholog, we tested the possibility that GA might inhibit it and thereby display antiparasitic activity. We provide direct recombinant DNA evidence for the Hsp90. Further modification generated tetrazole-chloroquine hybrids 33, and all hybrids showed promising in vitro antiplasmodial activities against chloroquine-sensitive 3D7 and chloroquine-resistant K1 and W2 strains of P. falciparum with IC 50 in a range of 0.006–3.505 μM.

    Hydroxychloroquine Dosage - Malaria Home Page The recommended hydroxychloroquine dosage for treating rheumatoid arthritis is 400 to 600 mg daily. For the treatment of lupus, the suggested dose is 400 mg once or twice daily. To prevent malaria in adults traveling to an area of high risk, the recommended dosage is 400 mg once weekly, starting two weeks before anticipated exposure.
