生物活性

Corylifol A inhibits IL-6-induced STAT3 activation and phosphorylation, with an IC50 of 0.81 μM.

IC50 & Target

STAT3

0.81 μM (IC50)

体外研究
(In Vitro)

Corylifol A shows an inhibitory effect on IL-6-induced STAT3 promoter activity in Hep3B cells with IC50 value of 0.81±0.15 μM, also inhibits STAT3 phosphorylation induced by IL-6 in Hep3B cells[1]. Corylifol A inhibits SARA PLpro in a dose-dependent manner with IC50s ranging between 4.2 and 38.4 μM[2]. Corylifol A is found to be a naturally occurring potent inhibitor of hCE2, with low Ki values ranging from 0.62 μM to 3.89 μM[3].
