Gastrointestinal nematodes are the major cause of animal diseases, and the indiscriminate use of synthetic anthelmintic contributes to the development of drug resistance. Natural bioproducts are noteworthy since they have proved to be promising for alternative antiparasitic therapies. This study evaluated the in vitro effect of WSMoL (water soluble Moringa oleifera lectin) on hatching of eggs and on the development of early-stage larvae of gastrointestinal nematodes from naturally infected goats. In addition, the interference of WSMoL on activity of proteases was determined and the affinity of the lectin for glycosylated molecules of these parasites was investigated using fluorescein isothiocyanate (FITC)-labeled WSMoL...

The flavonoid natural compound chlorflavonin was isolated from the endophytic fungus Mucor irregularis, which was obtained from the Cameroonian medicinal plant Moringa stenopetala. Chlorflavonin exhibited strong growth inhibitory activity in vitro against Mycobacterium tuberculosis (MIC90 1.56 μM) while exhibiting no cytotoxicity towards the human cell lines MRC-5 and THP-1 up to concentrations of 100 µM. Mapping of resistance-mediating mutations employing whole-genome sequencing, chemical supplementation assays, molecular docking studies as well as enzymatic characterization revealed that chlorflavonin specifically inhibits the acetohydroxyacid synthase catalytic subunit IlvB1, causing combined auxotrophies to branched chain amino acids and to pantothenic acid...
