Ein neuer Malariawirkstoff hemmt die Proteinsynthese von Plasmodium falciparum

Angewandte Chemie, Volume 137, Issue 49, December 1, 2025.
Die Verbindung 31 stellt einen vielversprechenden Ansatz für die Entwicklung eines Malariawirkstoffs mit einem starken Wirkungsprofil dar (PfNF54 IC50 ± s.d. = 3,9 ± 0,4 nM). Sie hat einen neuartigen Wirkmechanismus, indem sie an zytosolische Ribosomen‐Untereinheiten bindet und dadurch die Proteinsynthese im Parasiten hemmt.

Simultaneous Spectrophotometric Estimation of Artesunate and Mefloquine

Journal of Chemistry, 2013
A simple, rapid, precise, and accurate UV-visible spectrophotometric method has been developed for the simultaneous determination of Artesunate in combination with Mefloquine. For developing the method, methanol was used as a solvent.

Adherence to a Six-Dose Regimen of Artemether-Lumefantrine for Treatment of Uncomplicated Plasmodium Falciparum Malaria in Uganda. [PDF]

, 2004
Measuring baseline levels of adherence and identifying risk factors for non-adherence are important steps before the introduction of new antimalarials. In Mbarara in southwestern Uganda, we assessed adherence to artemether-lumefantrine (Coartem) in its ...

A Novel Antimalarial Agent that Inhibits Protein Synthesis in Plasmodium falciparum

Angewandte Chemie International Edition, Volume 64, Issue 49, December 1, 2025.
Compound 31 represents a promising avenue for the development as an antimalarial agent with a potent activity profile (PfNF54 IC50 ± s.d. = 3.9 ± 0.4 nM). It has a novel mode of action by binding to cytosolic ribosomal subunits, thereby inhibiting protein synthesis in the parasite.

Artemisinin: From Chinese Herbal Medicine to Modern Chemotherapy [PDF]

, 2019
Malaria is a disease that has blighted humankind since early times. The first antimalarial treatment available to Europeans was the dried bark of the cinchona tree from Peru. The main problem in its use was adulteration by other material.

Tandem Mass Spectrometry and Bio‐Guided Isolation of Secondary Metabolites With Antiplasmodial Activity From Dalbergia miscolobium Bark

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT Strategies have been employed to address antimalarial drug resistance, including the exploration of new therapeutic targets. In this study, the stem bark of Dalbergia miscolobium was investigated using in vitro assays against Plasmodium falciparum and pyruvate kinase II (PyrKII), an essential enzyme for parasite development.

Stimulation of Suicidal Erythrocyte Death by Artesunate

Cellular Physiology and Biochemistry, 2014
Background: The artemisinin derivative artesunate is effective in the treatment of severe malaria and is considered for the treatment of malignancy. Artesunate triggers tumor cell apoptosis, an effect at least in part mediated by mitochondria.

Artemether resistance in vitro is linked to mutations in PfATP6 that also interact with mutations in PfMDR1 in travellers returning with Plasmodium falciparum infections. [PDF]

, 2012
BACKGROUND: Monitoring resistance phenotypes for Plasmodium falciparum, using in vitro growth assays, and relating findings to parasite genotype has proved particularly challenging for the study of resistance to artemisinins.

Overcoming BET‐inhibitor JQ1 resistance in aggressive non‐small cell lung cancer by inducing ferroptosis via inhibition of the BRD2–FTH1 axis

The FEBS Journal, Volume 292, Issue 23, Page 6345-6364, December 2025.
Recent studies emphasize alternative functions of FTH1 relevant for nuclear processes, such as transcriptional regulation. This study shows a novel FTH1/BRD2 association in non‐small cell lung carcinoma (NSCLC). This nuclear interaction affects BRD2 protein stability in aggressive NSCLC cells.

Are transnational tobacco companies' market access strategies linked to economic development models? A case study of South Korea. [PDF]

, 2013
Transnational tobacco companies (TTCs) have used varied strategies to access previously closed markets. Using TTCs' efforts to enter the South Korean market from the late 1980s as a case study, this article asks whether there are common patterns in these
