In Vitro
STAT3 antagonist-1 (Compound P42) (10-50 μM) selectively targets the STAT3 SH2 domain over the DNA-binding domain, as demonstrated by potent inhibition in the STAT3127-688:phosphopeptide FP assay (85% at 10 μM) with a selectivity ratio of 5.00[1].
STAT3 antagonist-1 (24-72 h) exhibits potent growth inhibition in KRAS-mutant MIA PaCa-2 (GI50 ~0.85 μM at 72 h) and HCT 116 (GI50 ~4.4 μM at 72 h) cancer cell lines[1].
STAT3 antagonist-1 (10 μM; 72 h) exhibits selective cytotoxicity toward cancer cell lines at 10 μM, with the highest growth inhibition in MIA PaCa-2 (75%), DLD-1 (77%), and HCT 116 (62%), and minimal effect on non-cancerous MC3T3-E1 cells[1].
STAT3 antagonist-1 (0.1-10 μM; 24-48 h) inhibits STAT3 phosphorylation in MIA PaCa-2 and HCT 116 cells without affecting the total protein levels of upstream kinases JAK2 and SRC[1].
STAT3 antagonist-1 (0.3-30 μM; 24-48 h) induces autophagy-associated cell death in MIA PaCa-2 and HCT 116 cells[1].
STAT3 antagonist-1 (0.3-30 μM; 24-48 h) activates autophagy in MIA PaCa-2 and HCT 116 cells, characterized by increased LC3II/I ratios and decreased p62 levels[1].
STAT3 antagonist-1 (0.3-30 μM) abrogates cancer stemness potential in MIA PaCa-2 and HCT 116 cells by inhibiting colony formation[1].
STAT3 antagonist-1 (0.3-3 μM) down-regulates EMT/stemness markers SNAIL and ZEB1 in MIA PaCa-2 and HCT 116 cells[1].
