STAT3-IN-32
STAT3-IN-32 is an orally active, selective STAT3 SH2 domain inhibitor with a Kd of 21.3 nM, showing selectivity over STAT1/5. STAT3-IN-32 binds to the STAT3 SH2 domain, blocks Tyr705 and Ser727 phosphorylation, abrogates nuclear transcription and mitochondrial oxidative phosphorylation functions. STAT3-IN-32 inhibits tumor growth in mouse pancreatic cancer xenograft models. STAT3-IN-32 can be used for the research of pancreatic cancer.

STAT3-IN-32 (compound 4c) potently inhibits STAT3 luciferase activity in HEK293T cells with an IC50 of 5.3 nM[1].
STAT3-IN-32 inhibits ATP production in BxPC-3 pancreatic cancer cells with an IC50 of 4.2 nM[1].
STAT3-IN-32 potently inhibits proliferation of STAT3-dependent BxPC-3, Capan-2, CFPAC-1, and MIA PaCa-2 pancreatic cancer cells with single-digit to low nanomolar IC50 values, but does not affect STAT3-negative PC-3 cell proliferation[1].
STAT3-IN-32 does not inhibit human CYP1A2, CYP2C9, CYP2C19, CYP2D6, or CYP3A4-M isoforms at concentrations up to 50 μM[1].
STAT3-IN-32 (0-1000 nM; 0-24 h) concentration- and time-dependently inhibits STAT3 Tyr705 and Ser727 phosphorylation and downstream c-Myc and Cyclin D1 expression in BxPC-3 and Capan-2 pancreatic cancer cells without altering total STAT3 levels, and has no effect on c-Myc or Cyclin D1 in STAT3-negative PC-3 cells[1].
STAT3-IN-32 does not inhibit STAT3 upstream kinases JAK1, JAK2, EGFR, SRC, ERK1, JNK1, or P38δ at concentrations up to 10 μM[1].
STAT3-IN-32 (0-30 nM) concentration-dependently blocks IL-6-induced STAT3 Tyr705 phosphorylation and subsequent nuclear translocation in BxPC-3 and Capan-2 pancreatic cancer cells[1].
STAT3-IN-32 (0-30 nM) concentration-dependently inhibits mitochondrial respiration, including basal respiration, maximal respiration, and ATP production-linked oxygen consumption, in BxPC-3 and CFPAC-1 pancreatic cancer cells[1].
