Summary
Funalenone is a fungal phenalenone that inhibits HIV-1 integrase and type I collagenase (MMP-1).
Details
Funalenone is a phenalenone secondary metabolite originally isolated from Aspergillus niger. It inhibits type I collagenase (MMP-1) and displays selective inhibition of HIV-1 integrase with micromolar potency, leading to suppression of viral replication in vitro. The compound shows greater activity against MMP-1 than against type IV collagenases and demonstrates favorable selectivity in antiviral assays. As a dual integrase and metalloproteinase inhibitor, funalenone represents a valuable phenalenone scaffold for antiviral and matrix biology research.
