Rapanone

Rapanone is a natural benzoquinone. Rapanone exhibits a broad spectrum of biological actions, including anti-tumor, antioxidant, anti-inflammatory, antibacterial and antiparasitic. Rapanone also is a potent and selective human synovial PLA2 inhibitor, with an IC50 of 2.6 μM[1][2][3][4].

ChEBI: Rapanone is a member of dihydroxy-1,4-benzoquinones.

PLA2: 2.6 μM (IC₅₀)
