    Galiellalactone

    $277.35 - $970.71
    Galiellalactone was originally isolated from Galiella rufa as a plant growth regulator.

    Galiellalactone is soluble in ethanol, methanol, DMF or DMSO. Poor water solubility.
    Mechanism of ActionRecently Galiellalactone was shown to inhibit IL-6 induced SEAP expression with IC50 values of 250-500 nM, 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.
