Characterization of novel antimalarial compound ACT-451840: preclinical assessment of activity and dose-efficacy modeling (Publications)
cycle stages of the human malaria parasite Plasmodium falciparum (asexual and sexual) and Plasmodium vivax (asexual) as well as oral in vivo efficacies in two murine malaria models that permit infection [...] determination of the dose-efficacy relationship of ACT-451840 under curative conditions in rodent malaria models allowed prediction of the human efficacious exposure. CONCLUSION: The dual activity of ACT-451840
Parasite-host dynamics throughout antimalarial drug development stages complicate the translation of parasite clearance (Publications)
Ensuring continued success against malaria depends on a pipeline of new antimalarials. Antimalarial drug development utilizes pre-clinical murine and experimental human malaria infection studies to evaluate
The potential of secondary metabolites from plants as drugs or leads against protozoan neglected diseases - part I (Publications)
neglect of public awareness in high income countries. Another major tropical protozoan disease is malaria (caused by various Plasmodium species), which -although not mentioned currently by the WHO as a neglected [...] represents a major problem, especially to people living under poor circumstances in tropical countries. Malaria causes by far the highest number of deaths of all protozoan infections and is often (as in this review)
Evaluation of Olyset trade mark insecticide-treated nets distributed seven years previously in Tanzania (Publications)
BACKGROUND: Insecticide-treated nets represent currently a key malaria control strategy, but low insecticide re-treatment rates remain problematic. Olyset trade mark nets are currently one of two long-lasting [...] polyester nets. Hence, Olyset trade mark nets are one of the best choices for ITN programmes in rural malaria-endemic areas
Antigenicity and immunogenicity of a novel <em>Plasmodium vivax</em> circumsporozoite derived synthetic vaccine construct (Publications)
BACKGROUND: The circumsporozoite (CS) protein is a major malaria sporozoite surface antigen currently being considered as vaccine candidate. Plasmodium vivax CS (PvCS) protein comprises a dimorphic central [...] VK210 and VK247. We studied the natural immune response to this region in human sera from different malaria-endemic areas and its immunogenicity in mice. RESULTS: PvNR1R2 was more frequently recognized by
In vitro antiplasmodial activity and toxicity assessment of some plants from Nigerian ethnomedicine (Publications)
Plasmodium falciparum-resistant parasites to nearly all available antimalarial drugs pose a threat to malaria control and necessitates the need to continue the search for new effective and affordable drugs. [...] displayed antiplasmodial activity (IC(50) 2.3-16.9 microg/mL) with good selectivity (21-120) for malaria parasites. DISCUSSION AND CONCLUSION: The antiplasmodial activity of Terminalia catappa and Vitex
Anti-protozoal activity of aporphine and protoberberine alkaloids from <em>Annickia kummeriae</em> (Engl. & Diels) Setten & Maas (Annonaceae) (Publications)
BACKGROUND: Malaria, trypanosomiasis and leishmaniasis have an overwhelming impact in the poorest countries in the world due to their prevalence, virulence and drug resistance ability. Currently, there [...] there is inadequate armory of drugs for the treatment of malaria, trypanosomiasis and leishmaniasis. This underscores the continuing need for the discovery and development of new anti-protozoal drugs. Consequently
Antiprotozoal effect of <em>Artemisia indica</em> extracts and essential oil (Publications)
All solvent extracts and the volatile oil showed in vitro antimalarial activity, plus a potential malaria prophylactic effect by inhibiting at least two recombinant plasmodial fatty acid biosynthesis (PfFAS-II) [...] detailed study investigating both artemisinin and polymethoxyflavonoid content as well as in vitro malaria prophylactic and detailed antiprotozoal potential of A. indica extracts against a panel of protozoan
Parasitic infections, anemia and malnutrition among rural settled and mobile pastoralist mothers and their children in Chad (Publications)
Chad. Intestinal parasites were evaluated using direct fecal smears and the Kato-Katz technique. Malaria status was determined using Paracheck-Pf((R)) rapid diagnostic test, and anemia was assessed with [...] common protozoan. The hookworm prevalence was 14% (CI 8-20) in women and 18% (CI 13-23) in children. Malaria prevalence was low among women (1%, CI 0.5-2) and children (3% CI 2-5). No significant difference
Comparative ex vivo activity of novel endoperoxides in multidrug-resistant <em>Plasmodium falciparum</em> and <em>P. vivax</em> (Publications)
potent compounds for the treatment of malaria. In Papua Indonesia, where multidrug resistance has been documented against both P. falciparum and P. vivax malaria, comparative ex vivo antimalarial activity
