Identification
Biological Activities
Uvaria alba serves as a significant source of bioactive compounds, particularly through its associated endophytic fungi. Research indicates that the endophytic fungus Diaporthe perseae, isolated from this endemic Philippine medicinal plant, produces potent antimicrobial secondary metabolites. Specifically, the study identified several anthraquinones, including rugulosin A, which demonstrate broad-spectrum activity against various bacterial strains. Notably, rugulosin A exhibits strong inhibitory effects against both Gram-negative bacteria and Mycobacterium tuberculosis by targeting the essential enzyme DNA gyrase. These findings highlight the therapeutic potential of metabolites derived from the biological environment of Uvaria alba in the development of new antibiotics.
