Biological Activity
Pomstafib-2 (compound 8) (0-10 µM; 4 h) decreases the expression of pSTAT5b in a dose-dependent manner in STAT5b-GFP-transfected K562 cells[1].
Pomstafib-2 (0, 10, 20, 40, 60, 80 µM; 48 h) induces apoptosis in a dose-dependent manner in STAT5-dependent K562 cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
