Trypanosome Infection

Venturicidin A (Aabomycin A1) is a natural product derived from Streptomyces, possessing antifungal, anti-Trypanosoma brucei, anti-Leishmania donovani, and ATP synthase inhibitory activities. Venturicidin A acts as an antibiotic adjuvant, promoting the uptake of aminoglycoside antibiotics and enhancing bactericidal efficacy. Venturicidin A inhibits ATP synthesis by blocking proton translocation through the F_O subunit. In bloodstream-form Trypanosoma brucei, Venturicidin A causes collapse of the mitochondrial membrane potential; in fungi, it disrupts cell membrane integrity, induces leakage of cytoplasmic contents, elevates ROS levels, and downregulates the expression of fungal pathogenicity-related genes. Venturicidin A exhibits antifungal activity against Botrytis cinerea. Venturicidin A is used in research on bacterial infections, trypanosome/leishmania infections, and gray mold disease.
