In vitro activities of pyronaridine, alone and in combination with other antimalarial drugs, against Plasmodium falciparum.
The in vitro activities of pyronaridine, alone and in combination with established antimalarial drugs, were assessed by isotopic microtest. Pyronaridine was highly active against all Cameroonian isolates. A positive correlation was observed between the response to pyronaridine and that to chloroquine. Drug combination studies showed synergy between pyronaridine and primaquine, additive effects ...
متن کاملInteractions of DB75, a novel antimalarial agent, with other antimalarial drugs in vitro.
Pafuramidine is a novel orally active antimalarial. To identify a combination partner, we measured the in vitro antimalarial activities of the active metabolite, DB75, with amodiaquine, artemisinin, atovaquone, azithromycin, chloroquine, clindamycin, mefloquine, piperaquine, pyronaridine, tafenoquine, and tetracycline. None of the drugs tested demonstrated antagonistic or synergistic activity i...
متن کاملIn vitro activity of pyronaridine against multidrug-resistant Plasmodium falciparum and Plasmodium vivax.
Pyronaridine, a Mannich base antimalarial, has demonstrated high in vivo and in vitro efficacy against chloroquine-resistant Plasmodium falciparum. Although this drug has the potential to become a prominent artemisinin combination therapy, little is known about its efficacy against drug-resistant Plasmodium vivax. The in vitro antimalarial susceptibility of pyronaridine was assessed in multidru...
متن کاملPotentiation of antimalarial drug action by chlorpheniramine against multidrug-resistant Plasmodium falciparum in vitro.
Chlorpheniramine, a histamine H1 receptor antagonist, was assayed for in vitro antimalarial activity against multidrug-resistant Plasmodium falciparum K1 strain and chloroquine-resistant P. falciparum T9/94 clone, by measuring the 3H-hypoxanthine incorporation. Chlorphenirame inhibited P. falciparum K1 and T9/94 growth with IC50 values of 136.0+/-40.2 microM and 102.0+/-22.6 microM respectively...
