C188 is a cell-permeable naphthol compound and a STAT3 inhibitor. C188 inhibits IL-6-stimulated STAT3 Tyr705 phosphorylation and nuclear translocation in HepG2 cells by targeting STAT3 SH2 domain peptide-binding pocket, while exhibiting little effect agai
AP-22161 selectively binds the Src SH2 domain by targeting highly conserved phosphotyrosine binding to cysteine residues in the pocket. AP-22161 selectively inhibits Src SH2 binding and can be used to inhibit osteoclast absorption.
AC-4-130, a powerful inhibitor of the SH2 domain of STAT5, effectively hinders STAT5 activation, dimerization, nuclear translocation, and transcription of genes reliant on STAT5. This compound directly binds to STAT5, ultimately leading to cell cycle arrest and apoptosis in FLT3-ITD-driven leukemic cells. AC-4-130 exhibits notable anti-cancer properties and effectively suppresses abnormal STAT5 activity in acute myeloid leukemia (AML), making it a promising therapeutic option [1].
