APTSTAT3-9R 

APTSTAT3-9R, a specific STAT3-binding peptide, inhibits STAT3 activation and downstream signaling by specifically blocking STAT3 phosphorylation. APTSTAT3-9R exerts antiproliferative effects and antitumor activity^[1].

APTSTAT3-9R (7.5, 15, and 30 μmol/L; 6 hours) significantly reduces STAT3–DNA-binding activity in a dose-dependent manner in human lung carcinoma cells (A549)^[1].
APTSTAT3-9R (30 μM; for 2 weeks) suppresses cell viability and proliferation of cancer cells and significantly suppresses colony formation. APTSTAT3-9R has IC50s of 10 to 20 μM in A549, B16F1 and HepG2 cells^[1].
APTSTAT3-9R (7.5, 15, and 30 μmol/L; 6 hours) effectively inhibits phosphorylation of STAT3 but does not affect the level of AKT phosphorylation, indicating specificity of the aptide^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

APTSTAT3-9R (8 mg/kg in 50 μL; intratumorally injected every other day for a total of four injections) suppresses tumor growth in 6-week-old female BALB/c nude mice with A549 cells^[1].
