MedKoo CAT#: 406527

CAS#: 1172133-28-6

Description: HO-3867 is a selective and potent STAT3 inhibitor. HO-3867 selectively inhibited STAT3 phosphorylation, transcription, and DNA binding without affecting the expression of other active STATs. HO-3867 exhibited minimal toxicity toward noncancerous cells and tissues but induced apoptosis in ovarian cancer cells. Pharmacologic analysis revealed greater bioabsorption and bioavailability of the active (cytotoxic) metabolites in cancer cells compared with normal cells. HO-3867 may be useful to treat ovarian cancer and other solid tumors where STAT3 is widely upregulated.
