STAT3 Inhibitor VI, S3I-201

A cell-permeable amidosalicylic acid compound that binds Stat3-SH2 domain and prevents Stat3 phosphorylation/activation, dimerization, DNA-binding, and Stat3-dependent transcription. Shown to arrest Stat3-dependent tumor growth both in cultures in vitro (effective conc. ≤100 µM) and in a murine xenograft model in vivo (5 mg/kg, i.v.).
