Norpterosin B exhibits potential in antimicrobial applications, particularly against certain Gram-positive bacteria. Studies suggest it may interfere with bacterial cell membrane integrity, leading to reduced viability. It has also shown moderate antifungal activity in preliminary in vitro tests. Due to its natural origin and structural profile, Norpterosin B is being explored as a lead compound in the development of new antimicrobial agents, especially in contexts where resistance to conventional antibiotics is a concern. Additionally, it may play a role in anti-inflammatory pathways, though this activity remains under investigation.
