C188-9 (TTI-101) 是 Stat3 的抑制剂，其 Kd 值为 4.7 nM。C188-9 抑制 G-CSF 诱导的 STAT3 激活和 STAT3 依赖性基因表达。C188-9 诱导 AML 细胞系和原代标本凋亡，抑制原代 AML 细胞集落形成。 Information C188-9 (TTI 101) is a potent inhibitor ofSTAT3that 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 (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. In vivo Treatment of nude mice bearing xenografts of UM-SCC-17B, a radioresistant HNSCC line, with C188-9, but not C188, prevented tumor xenograft growth. C188-9 was well tolerated in mice, showed good oral bioavailability, and was concentrated in tumors.
