In vitro potentiation of antibiotic activities by a catecholate iron chelator against chloroquine-resistant Plasmodium falciparum.
نویسندگان
چکیده
FR160, a catechol iron chelator, and tetracyclines or norfloxacin exert in vitro additive or synergistic activity against a chloroquine-resistant Plasmodium falciparum clone. FR160 shows antagonistic effects in association with macrolides, ofloxacin, and rifampin.

Synthesis and study of effects of new 4-chloro – amodiaquine analogues against two resistant and sensitive forms to chloroquine Plasmodium Falciparum, in vitro
Background: Resistance to chloroquine (CQ) in Plasmodium falciparum malaria has become a major health concern of the developing countries.This resistance has prompted a re-examination of the pharmacology of alternative antimalarials that may be effective against resistant strains. Amodiaquine (AQ) is a 4-aminoquinoline antimalarial which is effective against many chloroquine-resistant strains o...
متن کاملIn Vitro Activity of Mefloquine and its Enantiomers Against Plasmodium falciparum
The in vitro activity of rac-mefloquine hydrochloride and its pure enantiomers was tested against a chloroquine-resistant (PF.IBS2) strain of Plasmodium falciparum. The parasite isolated from Iranian patients was cultured in vitro by the candle jar method described by Tranger and Jensen and was exposed to the racemic mefloquine or its enantiomers over the concentration range of 10-9 to 10-4 M. ...
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...
متن کاملEvaluation of the sensitivity in vitro of Plasmodium falciparum and in vivo of Plasmodium chabaudi Malaria to various drugs and their combinations.
K1 strain of Plasmdoium falciparum is resistant in vitro to chloroquine, pyrimethamine and sulfadoxine. Response of this strain to combinations of antimalarial drugs in the in vitro hypoxanthine incorporation test was coupled with that of a line of strain NF54 relatively sensitive to chloroquine and fully sensitive to other antimalarials. Pyrimethamine and sulfadoxine showed potentiative synerg...
