Description

STAT3-IN-3 is a potent and selective inhibitor of signal transducer and activator of transcription 3 (STAT3), with anti-proliferative activity. STAT3-IN-3 induces apoptosis in breast cancer cells. STAT3-IN-3 acts as a promising mitochondria-targeting STAT3 inhibitor for cancer research.

How to use

In Vitro:

STAT3-IN-3 has no influence on the phosphorylation levels of STAT1, JAK2, Src and Erk1/2. STAT3-IN-3 inhibits the growth of MDA-MB-231, HCT-116, HepG2, and MCF-7 cells with IC50s of 1.43 μM, 1.89 μM, 2.88 μM, and 3.33 μM, respectively. STAT3-IN-3 down-regulates the expression of STAT3 target genes Bcl-2 and Cyclin D1. STAT3-IN-3 inhibits STAT3 tyrosine phosphorylation and serine phosphorylation. STAT3-IN-3 inhibits STAT3 DNA-binding activity. STAT3-IN-3 (1-4 μM; 24 hours) increases ROS production and remarkably reduces the mitochondrial membrane potential to induce mitochondrial apoptotic pathway. STAT3-IN-3 (1-4 μM; 24 hours) can induce the cleavage of caspase-9, caspase-3 and PARP.

In Vivo:

STAT3-IN-3 (10mg/kg-20 mg/kg; i.p.; daily; for 14 days) possesses potent antitumor activity against implanted 4T1 breast tumors growth.
