Stafib-2 is a potent and selctive inhibitor of the transcription factor STAT5b, with an IC50 of 82 nM and 1.7 μM for STAT5b and STAT5a, respectively. Stafib-2 exhibits poor cell permeability[1].
Stafib-2 has an extremely high affinity for STAT5b (Ki=8.8 nM)[1].
Stafib-2 (3-10 μM; 4-48 h) does not show significant activity in K562 and MDA-MB-231 cells[1].
