Galiellalactone was originally isolated from Galiella rufa as a plant growth regulator. Recently it was shown to inhibit IL-6 induced SEAP expression with IC50 values of 250-500nM by blocking the binding of the activated Stat3 dimers to their DNA binding sites without inhibiting the tyrosine and serine phosphorylation of the Stat3 transcription factor.
