Effusanin B is primarily used for its antimicrobial properties, particularly against Gram-positive bacteria. It shows potential in pharmaceutical applications where natural compounds are explored for antibiotic development. Research indicates activity in inhibiting biofilm formation, which is valuable in treating persistent bacterial infections. It has also been investigated for antifungal use, especially in agricultural settings to control plant pathogens. Due to its natural origin, Effusanin B is studied as a lead compound in developing safer antimicrobial agents with lower toxicity and environmental impact.
