Targeting the intra-erythrocytic life cycle of Plasmodium falciparum unveils antimalarial drug discovery starting points from Drymaria cordata and Macaranga monandra.

Ethnopharmacological Relevance: Drymaria cordata and Macaranga monandra are two medicinal plants traditionally used in Cameroon to treat malaria, but their scientific validation remains unclear.

Aim Of The Study: To validate the antiplasmodial action of extracts and fractions derived from Drymaria cordata and Macaranga monandra.

Materials And Methods: Aqueous, methanolic, ethanolic, and hydroethanolic extracts of D.

A bio-guided investigation of Mitragyna inermis (Willd) O. Kuntze (Rubiaceae) unveils natural product isolates with potent cross-activity against sensitive and multidrug resistant Plasmodium falciparum strains in vitro.

Ethnobotanical Relevance: Malaria remains a significant global health challenge, especially in sub-Saharan Africa, with rising resistance to artemisinin-based therapies highlighting the urgent need for new, effective, and safer treatments from medicinal plants which have been used by the indigenous people.

Aim Of The Study: This study investigates the antiplasmodial potential of natural products from Mitragyna inermis.

Methods: Crude extracts from the stem bark and twigs of Mitragyna inermis were prepared using various solvents (water, ethanol/water, ethanol, and methanol) and tested for activity against Plasmodium falciparum strains Dd2 and 3D7 using the SYBR Green I-based fluorescence assay.

Bio-guided investigation of nine Niger's ethnomedicinal plants reveals nature-derived antimalarial chemical pharmacophores for drug discovery.

Malaria is a significant concern due to the emergence of artemisinin-resistant parasites. This study aims to unveil the selective inhibitory potential of extracts and derivatives of some Niger's plants against Plasmodium falciparum. Plant extracts were screened on chloroquine-sensitive (Pf3D7) and multidrug-resistant (PfDd2) P.

Natural products as transmission-blocking agents against malaria: a comprehensive review of bioactive compounds and their therapeutic potential.

Malaria eradication is hindered by the persistence of transmission stages of Plasmodium falciparum that enable parasite transfer from humans to mosquitoes. Current therapeutic strategies, such as artemisinin-based combination therapy (ACT) combined with primaquine, are insufficient due to limited efficacy on mature gametocytes and safety concerns in populations with glucose-6-phosphate dehydrogenase deficiency. This highlights the critical need for innovative, safe, and effective transmission-blocking interventions.

Repurposing DrugBank compounds as potential Plasmodium falciparum class 1a aminoacyl tRNA synthetase multi-stage pan-inhibitors with a specific focus on mitomycin.

Plasmodium falciparum aminoacyl tRNA synthetases (PfaaRSs) are potent antimalarial targets essential for proteome fidelity and overall parasite survival in every stage of the parasite's life cycle. So far, some of these proteins have been singly targeted yielding inhibitor compounds that have been limited by incidences of resistance which can be overcome via pan-inhibition strategies. Hence, herein, for the first time, we report the identification and in vitro antiplasmodial validation of Mitomycin (MMC) as a probable pan-inhibitor of class 1a (arginyl(A)-, cysteinyl(C), isoleucyl(I)-, leucyl(L), methionyl(M), and valyl(V)-) PfaaRSs which hypothetically may underlie its previously reported activity on the ribosomal RNA to inhibit protein translation and biosynthesis.

Anti-Shigella and antioxidant-based screening of some Cameroonian medicinal plants, UHPLC-LIT-MS/MS fingerprints, and prediction of pharmacokinetic and drug-likeness properties of identified chemicals.

Ethnopharmacological Relevance: Shigella infection is a public health problem responsible for approximately 700,000 deaths annually. The management of this disease is impaired by the emergence of multidrug-resistant Shigella species, highlighting the urgent need to search for alternative treatment options. In this regard, investigating medicinal plants traditionally used for the treatment of dysentery, diarrheal infections, and/or associated symptoms in endemic regions might provide an opportunity to identify phytochemicals that could be further used as a basis for the development of future anti-shigella drug candidates.

In vitro antiplasmodial activity and toxicological profile of extracts, fractions and chemical constituents of leaves and stem bark from Dacryodes edulis (Burseraceae).

Background: Dacryodes edulis is a plant that belongs to the Burseraceae family. It is widely used traditionally alone or in association with other plants in Cameroonian folk medicine to cure wounds, fever, headaches, and malaria. The aim of this work was to investigate the leaves and stem bark of D.

In vitro antiplasmodial activity-directed investigation and UPLC-MS fingerprint of promising extracts and fractions from Terminalia ivorensis A. Chev. and Terminalia brownii Fresen.

Ethnopharmacological Significance: Medicinal plants from the Terminalia genus are widely used as remedies against many infectious diseases, including malaria. As such, Terminalia ivorensis A. Chev.

Constituents from ripe figs of Ficus vallis-choudae Delile (Moraceae) with antiplasmodial activity.

Ripe figs, barks, and wood of Ficus vallis-choudae are used in traditional medicine against several conditions including nausea and malaria. However, its use is still to be scientifically documented and validated. Hence, the aim of the present work was to evaluate the antiplasmodial activity of the dichloromethane-methanol (DCM-MeOH (1:1)) crude extract, their hexane, dichloromethane, ethyl acetate, and methanoli fractions, as well as the isolated chemical constituents.
