STAT3-IN-32

Description

STAT3-IN-32 compound 2p is an orally active, potent STAT3 dual phosphorylation inhibitor with an indole-containing tetra-aromatic heterocycle scaffold. STAT3-IN-32 exhibits STAT3 luciferase inhibition activity using HEK293T cells with an IC50 of 5.3 nM and ATP production inhibition activity using BxPC-3 cells with an IC50 of 4.2 nM. STAT3-IN-32 significantly blocks p-Tyr705 and p-Ser727 and causes the abrogation of the corresponding nuclear transcription and mitochondrial oxidative phosphorylation functions of STAT3 by targeting the STAT3 SH2 domain KD=21.3 nM . STAT3-IN-32 exhibits significant suppressive effects in a pancreatic cancer xenograft model.
