Biological Activity
Small molecule inhibitor of STAT3. Inhibits binding of tyrosine-phosphorylated peptide motifs to STAT3 SH2 domain and inhibits STAT3 activation, dimerization and nuclear translocation. Displays selectivity over STAT1, STAT5, c-Myc/Max, Jun/Jun and Lck. Induces apoptosis in STAT3-dependent cancer cell lines.
