STAT3-IN-13

Research use only, not for human use.

STAT3-IN-13 is a potent STAT3 inhibitor.STAT3-IN-13 has antiproliferative and anticancer activity and acts by binding to the structural domain of STAT3 SH2.

STAT3-IN-13 (compound 6f) is a potent STAT3 inhibitor. STAT3-IN-13 has anti-proliferative effects and binds to the STAT3 SH2 domain with a KD of 0.46 μM. STAT3-IN-13 inhibits the phosphorylation of STAT3 Y705 and downstream target gene expression. STAT3-IN-13 induces apoptosis in vitro and suppresses the growth and metastasis of tumor in vivo. STAT3-IN-13 can be used for cancer research.

STAT3-IN-13 (compound 6f) (48 hours) has anti-proliferative activity with IC50 values of 0.25, 0.11 and 0.55 μM for 143B, HOS and MG63 cells, respectively.STAT3-IN-13 (compound 6f) (0.001-100 μM) binds to STAT3 and interacts with STAT3586?685 in a concentration dependent manner with a KD of 0.96 μM.STAT3-IN-13 (compound 6f) (0-1.0 μM; 24 hours; 143B and HOS cells) inhibits STAT3 Y705 phosphorylation and suppresses STAT3 in tumor cells.STAT3-IN-13 (compound 6f) (0-1.0 μM; 48 hours; 143B cells) induces apoptosis in a dose-dependent manner.Apoptosis Analysis Cell Line:143B cells Concentration:0, 0.2, 0.5, and 1 μM Incubation Time:48 hours Result:Increased the percentage of apoptosis rates of 3.4%, 8.7%, 10.7%, and 23.3% at 0, 0.2, 0.5 and 1 μM, respectively. Western Blot Analysis Cell Line:143B and HOS cells Concentration:0, 0.2, 0.5 and 1.0 μM Incubation Time:24 hours Result:Inhibited STAT3 Y705 phosphorylation and downstream target gene expression including Bcl-2 and VEGF, retained good antitumor activities against control tumor cells without STAT3 knockdown.

STAT3-IN-13 (compound 6f) (10-20 mg/kg; i.p.; twice daily, for 4 weeks; nude mice) blocks osteosarcoma growth and metastasis in vivo.Animal Model:Nude mice Dosage:10 and 20 mg/kg Administration:Intraperitoneal injection; twice daily, for 4 weeks Result:Suppressed tumor weight at a dose of 10 mg/kg.
