Cycloechinulin

Cycloechinulin is an unusual diketopiperazine isolated from Aspergillus ochraceus. Cycloechinulin has not been extensively studied but exhibits insecticidal activity against the lepidopteran crop pest, Helicoverpa zea. Recently, cycloechinulin has found use as a secondary metabolite standard for polyphasic taxonomy in Aspergillus.

Cycloechinulin is soluble in ethanol, methanol, DMF and DMSO.
