Biological Activity

Description C188-9 (TTI 101) is a potent inhibitor of STAT3 that binds to STAT3 with high affinity (KD=4.7±0.4 nM). C188-9 is well tolerated in mice, shows good oral bioavailability, and is concentrated in tumors.
Targets
STAT3 [1]
(Cell-free)
4.7 nM(Kd)
In vitro

C188-9 is a small-molecule inhibitor of Stat3 that targets the phosphotyrosyl peptide binding site within the Stat3 Src homology 2 (SH2) domain with Ki 136 nM. It does not inhibit upstream Jak or Src kinases[1].
