STAT3-IN-3 is a potent and selective inhibitor of signal transducer and activator of transcription 3 (STAT3).

STAT3-IN-31 (compound K2071), derived from STATtic, acts as an inhibitor of both STAT3 and mitotic processes. This compound interrupts mitotic progression and impacts the formation of the mitotic spindle. Additionally, STAT3-IN-31 hampers migration in glioblastoma cells, suppresses cellular proliferation within tumor spheroids, induces senescence in glioblastoma, and inhibits the growth of Temozolomide-resistant cells while reducing the secretion of the pro-inflammatory cytokine monocyte chemoattractant protein (MCP-1).

STAT3-IN-34 (Compound 15E) acts as a STAT3 inhibitor, blocking both the nuclear translocation and the transcriptional regulator activity of STAT3. It effectively inhibits HaCaT cell proliferation with an IC50 value of 0.008 μM. Additionally, STAT3-IN-34 reduces IL-17A expression and mitigates Imiquimod-induced psoriasis in mouse models.

STAT3-IN-36 (compound 11g) is a tritarget inhibitor that selectively targets LRPPRC, STAT3, and CDK1, exhibiting potent anticancer activity. This compound binds to LRPPRC, STAT3, and CDK1, demonstrating more effective anticancer effects than those of TMF or Capecitabine. Additionally, STAT3-IN-36 exhibits an IC50 value of 1.8 μM in HGC27 cells.

STAT3-IN-39 (compound 10K) is an orally active inhibitor of STAT3, demonstrating effective inhibition of STAT3 phosphorylation with an IC50 of 0.47 μM in NIH-3T3 cells. It hinders TGF-β1-induced fibrotic responses and prevents epithelial-mesenchymal transition in A549 cells. STAT3-IN-39 is applicable for research related to idiopathic pulmonary fibrosis.

STAT3-IN-38 (Compound 4m) is a STAT3 inhibitor with a dissociation constant (K_D) of 45.33 µM for rhSTAT3, and is a derivative of Celastrol. It binds to the SH2 domain of the STAT3 protein, inhibiting phosphorylation at the pTyr705 site and suppressing downstream gene expression of Survivin and Mcl-1. STAT3-IN-38 can arrest the cell cycle and induce apoptosis in colorectal cancer cells.

STAT3-IN-37 (Compound 101) is an inhibitor of STAT3, with an IC50 of 15 nM as measured by DNA-HTRF assay and 2 nM as determined through human whole blood SOCS3 qPCR assay.
