STAT3-IN-51
STAT3-IN-51 is a STAT3 inhibitor that directly binds to the STAT3 SH2 domain. STAT3-IN-51 induces apoptosis, ferroptosis, and immunogenic cell death (ICD) to potentiate anti-tumor immunity. STAT3-IN-51 inhibits STAT3 activation (phosphorylation, p-STAT3) and its downstream signaling. STAT3-IN-51 induces ROS generation, decreases Bcl-2 expression, disruptes mitochondrial function, suppresses GPX4 activity, and promotes lipid peroxidation. STAT3-IN-51 can be used for the study of colorectal carcinoma, breast adenocarcinoma, non-small cell lung cancer (NSCLC) and Cisplatin (HY-17394)-resistant pulmonary adenocarcinoma.

In Vitro
STAT3-IN-51 (Compound 8d) (48 h) exhibits IC50 values of 0.26 μM, 0.34 μM, 0.61 μM, and 0.67 μM against SW480, MDA-MB-231, A549, and A549/DDP cells, respectively[1].
STAT3-IN-51 (0.3 μM; 24 h) induces apoptosis in SW480 cells through mitochondrial dysfunction and caspase activation[1].
STAT3-IN-51 (0.3 μM; 24 h) effectively inhibits both total STAT3 and p-STAT3 in SW480 cells[1].
STAT3-IN-51 (0.3 μM; 24 h) enhances CD8+ T lymphocyte infiltration and expansion[1].
STAT3-IN-51 (0.3 μM; 24 h) enhances dendritic cell maturation and reduces HMGB1 levels[1].
STAT3-IN-51 (0.3 μM; 24 h) induces ferroptosis in SW480 cells through GPX4 suppression and lipid peroxidation[1].

-
Animal Model:Male BALB/c mice (5-week-old) bearing CT26 tumor xenografts[1]
-
Dosage:5 mg/kg, 10 mg/kg
-
Administration:i.p. (intraperitoneal); every two days for 13 days
-
Result:Achieved 63.17% tumor growth inhibition (TGI) at 5 mg/kg, and 75.62% TGI at 10 mg/kg.
At 10 mg/kg, shows better tolerability.
