Antitrypanosomal Activity and Molecular Docking Studies of Lobetyolin From <i>Lobelia rhynchopetalum</i> Hemsl. Root Extract Against <i>Trypanosoma congolense</i> Field Isolates.

ABSTRACT: Currently available drugs for trypanosomiasis are few, and their use is limited by toxicity and growing resistance. This highlights the need for safer and more effective alternatives. In this study, the in vitro and in vivo antitrypanosomal activities of an 80% methanol root extract of Lobelia rhynchopetalum and its major constituent were evaluated against Trypanosoma congolense field isolates. Phytochemical separation of the extract yielded lobetyolin (a polyacetylene compound), confirmed through spectroscopic analysis. At 4 mg/mL, both the crude extract and lobetyolin inhibited parasite motility, with lobetyolin acting slightly faster (25 min) than the extract (30 min). The blood incubation assay demonstrated dose-dependent protection, with 4 mg/mL of DA, the lobetyolin-ric
