C188-9

Chemical Information
STAT3 Inhibitor C-188-9 is an orally bioavailable, binaphthol-sulfonamide-based inhibitor of signal transducer and activator of transcription 3 (STAT3), with potential antineoplastic activity. Upon oral administration, the STAT3 inhibitor C-188-9 specifically targets and binds to the phosphotyrosyl peptide binding site within the Src homology 2 (SH2) domain of STAT3. This inhibits the Janus kinase (JAK)-mediated tyrosine phosphorylation and activation of STAT3. This impedes nuclear translocation of STAT3, prevents STAT3 binding to responsive gene promoters and blocks STAT3-mediated regulation of gene expression. STAT3 regulates the transcription of genes involved in several cellular functions. STAT3 is constitutively activated in a variety of human cancers and plays a key role in neoplastic transformation, uncontrolled tumor cell proliferation, resistance to apoptosis, metastasis, immune evasion, tumor angiogenesis, epithelial-mesenchymal transition (EMT) and the Warburg effect.
