Corylifol A inhibits IL-6-induced STAT3 activation and phosphorylation, with an IC 50 of 0.81 μM. In Vitro Corylifol A shows an inhibitory effect on IL-6-induced STAT3 promoter activity in Hep3B cells with IC 50 value of 0.81±0.15 μM, also inhibits STAT3 phosphorylation induced by IL-6 in Hep3B cells. Corylifol A inhibits SARA PLpro in a dose-dependent manner with IC 50 s ranging between 4.2 and 38.4 μM. Corylifol A is found to be a naturally occurring potent inhibitor of hCE2, with low K i values ranging from 0.62 μM to 3.89 μM. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:STAT3 0.81 μM (IC 50 )
