Faradiol
Faradiol is a STAT3 inhibitor. Faradiol exerts anti-inflammatory activity by reducing STAT3 phosphorylation in a concentration-dependent manner and inhibiting LPS-induced IL-6 release from human monocytes, while also exhibiting cytotoxicity against leukemia and non-small cell lung cancer cells. Faradiol can be used in research on leukemia, edema, cancer, non-small cell lung cancer, Phorbol 12-myristate 13-acetate (TPA) (HY-18739)-induced inflammation, and skin tumors.

In Vitro
Faradiol (10-4 M; 48 h) exhibits selective cytotoxicity against CCRF-CEM, K-582, SR, and EKVX human cancer cell lines, with GI50 values of 2.2-4.2 µM, and shows moderate cytotoxicity against the remaining tested NCI 60 cell lines (GI50, 10.5-86.9 µM)[6].
Faradiol (20 μM) reduces STAT3 phosphorylation in THP-1 monocytes without affecting NF-κB p65 phosphorylation[1].
Faradiol (20 µM; 30 min-24 h) inhibits LPS-induced IL-6 release in THP-1 human monocytes by 59%[2].
Faradiol (20 µM) reduces STAT3 phosphorylation but not NF-κB p65 phosphorylation in THP-1 human monocytes[2].
