Betaenone

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

Members of this class of chemical compounds include:
 * Betaenone A
 * Betaenone B
 * Betaenone C



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