| | C188-9 Usage And Synthesis |
| Uses | C188-9 (TTI-101) is a STAT3 inhibitor, with a Kd of 4.7 nM. C188-9 inhibits G-CSF-induced STAT3 activation and STAT3-dependent gene expression. C188-9 induces apoptosis in AML cell lines and primary samples and inhibits colony formation by primary AML blasts[1][2][3][4]. | | Biological Activity | C188-9 (TTI 101) is a potent STAT3 inhibitor, binds STAT3 with high affinity, Kd=4.7±0.4 nM. It is well tolerated in mice, has good oral bioavailability, and is mainly enriched in tumor tissues. | | in vitro | C188-9 is a small molecule inhibitor of STAT3, targeting the phosphotyrosine peptide binding site in the SH2 region of STAT3 with a Ki value of 136 nM. It does not inhibit upstream Jak or Src kinases. | | in vivo | C188-9 inhibited tumor growth in mice bearing UM-SCC-17B xenografts after administration of C188-9. C188-9 was well tolerated in mice, had good oral bioavailability, and was concentrated in tumor tissue after administration. | | target | | Target | Value | STAT3
