Betaenone

Betaenones are phytotoxins found in the fungus Pleospora betae.[1] The compounds were found to inhibit a variety of protein kinases.[2]

Molecular structures of betaenone A, B and C.

Two further betaenones were found in a species of the fungus Microsphaeropsis, which was isolated from the marine sponge Aplysina aerophoba.[3]
