Application

S3I-201 has been used as a signal transducer and activator of transcription 3 (STAT3) inhibitor:
  • to confirm the role of STAT3 phosphorylation in interleukin (IL)-33 production in lung epithelial cells and IL-22 mRNA expression in sorted group 3 innate lymphoid cells (ILC3s)
  • to study the cellular response of STAT3 triggered by β-hexaclorocyclohexane (β-HCH) in various cell lines
  • to examine the influence of STAT3 in response to angiotensin II (ang II) on induction of fibrotic proteins in kidney epithelial cells

Biochem/physiol Actions

Inhibition of signal transducer and activator of transcription 3 (STAT3) activity by S3I-201 may be a potential therapeutic strategy for hypertensive kidney disease.
S3I-201 is a cell-permeable Stat3 inhibitor that binds to the Stat3-SH2 domain, prevents Stat3 phosphorylation/activation, dimerization, and DNA-binding.

Cisplatin (CDDP) is frequently used in combination chemotherapy with paclitaxel for treating urothelial carcinoma of the urinary bladder (UCUB). CDDP cross-resistance has been suggested to develop with paclitaxel, thus hindering successful UCUB treatment. Therefore, elucidating the mechanisms underlying CDDP-induced anticancer
