Antimalarial agents have been widely used as disease-modifying antirheumatic drugs in the treatment of systemic lupus erythematosus (SLE) and other rheumatological diseases, although their mechanism of action has not yet been fully defined. It is known, however, that effective response to treatment is variable among patients. Thus, the identification of genetic predictors of treatment response ...

Comprehensive assessment of antimalarial drug resistance should include measurements of antimalarial blood or plasma concentrations in clinical trials and in individual assessments of treatment failure so that true resistance can be differentiated from inadequate drug exposure. Pharmacometric modeling is necessary to assess pharmacokinetic-pharmacodynamic relationships in different populations ...

Chalcones (1, 3, diaryl-2-propen-1-ones), are one of the plant secondary metabolite belonging to flavonoid family and has been widely explored in past decennium for its various pharmacological activities including antimalarial activity. Plasmodium aspartate proteases and cysteine proteases are the promising targets in malarial chemotherapy to overcome the drug resistance. Chalcones supposed to ...

The emergence of chloroquine resistance in Plasmodium falciparum has necessitated the development of alternate strategies for chemotherapy and chemoprophylaxis. One approach has been the identification of drugs that do not possess any intrinsic antimalarial activity when used alone but that potentiate the effect of currently available antimalarial drugs, such as chloroquine. We identified fluox...

Drug resistance is a recurrent problem in the fight against malaria. Genetic and epidemiological surveillance of antimalarial resistant parasite alleles is crucial to guide drug therapies and clinical management. New antimalarial compounds are currently at various stages of clinical trials and regulatory evaluation. Using ∼2000 Plasmodium falciparum genome sequences, we investigated the genetic...

A large number of piperidyl quinolinemethanols were investigated for antimalarial activity in avian infections because of close chemical similarity to quinine, as part of the wartime search for new and more effective antimalarial agents. In preliminary observations, SN-10,275,3 or 6,8-dichloro-2phenyl-a-2-piperidyl4-quinolinemethanol (Figure 1), gave greatest indication of promise. It is a comp...

The leaf, root, and stem extracts of Brucea javanica were screened for phytochemical properties and antimalarial activity, after extractions with various organic solvents. Qualitative analysis of the phytochemical constituents showed the presence of the following secondary metabolites: terpenoids, saponins, flavonoids, steroids, phenols, glycosides, alkaloids, and anthraquinones. The extracts s...

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...

A rapid, semiautomated microdilution method was developed for measuring the activity of potential antimalarial drugs against cultured intraerythrocytic asexual forms of the human malaria parasite Plasmodium falciparum. Microtitration plates were used to prepare serial dilutions of the compounds to be tested. Parasites, obtained from continuous stock cultures, were subcultured in these plates fo...

Development of new and more powerful antimalarial drugs has become more complex because of emergence of multidrug resistant strains of P. falciparum. Due to resistance of malaria parasite against well-known available drugs, the chemotherapy of malaria has become more complex and challenging. In this review we have discussed the life cycle of malaria parasite followed by quinoline based antimala...
