HO-3867 is a novel curcumin analog and a selective inhibitor of STAT3. 
STAT3 (signal transducer and activator of transcription 3) belongs to the STAT protein family. It mediates various gene expressions for numerous cellular functions, including cell growth, division and apoptosis.
HO-3867 selectively blocked STAT3 phosphorylation, transcription, and DNA binding without inhibiting other STATs proteins. It activated apoptosis in ovarian cancer cells and showed minimal toxicity to healthy cells.  HO-3867 also significantly inhibited the proliferation of serum-stimulated SMCs and elevated the phosphorylated and total levels of PTENs in SMCs.  By inducing cell cycle arrest and apoptosis, HO-3867 reduced the high levels of pSTAT3 Ser727 in endometrial cancer cells. 
In mice tumor xenograft, HO-3867 inhibited the tumor growth without toxic side effects, it also blocked PSTAT3/JAK1 and increased apoptotic marker cleaved Caspase 3/PARP.   After rat carotid artery injury, HO-3867 inhibited neointima formation and upregulated PTEN expression.
