    Product Description

    HO-3867 is an analog of curcumin (Item No. 81025) that selectively suppresses STAT3 phosphorylation, transcription, and DNA binding without affecting the expression of other active STATs.1,2 It has been shown to induce apoptosis in BRCA-mutated ovarian cancer cells with minimal toxicity to normal cells.2,3 HO-3867 is reported to demonstrate synergistic inhibition of chemotherapy-resistant ovarian xenograft tumors when combined with cisplatin (Item No. 13119).1,2

    WARNING This product is not for human or veterinary use.
