Nepetoidin B exhibits strong antioxidant properties, making it valuable in protecting cells from oxidative stress and free radical damage. It has shown potential in anti-inflammatory applications by inhibiting key inflammatory pathways, which may support its use in managing chronic inflammatory conditions. Research also indicates neuroprotective effects, suggesting possible roles in preventing neurodegenerative disorders such as Alzheimer’s and Parkinson’s diseases. Additionally, Nepetoidin B demonstrates antiviral activity, particularly against certain enveloped viruses, highlighting its relevance in developing antiviral therapies. Its ability to modulate metabolic enzymes may contribute to hepatoprotective effects, offering benefits in liver health and detoxification processes. These diverse biological activities make Nepetoidin B a promising candidate for pharmaceutical and nutraceutical development.
