AC-4-130
Based on 8 publication(s) in Google Scholar
AC-4-130 is a potent STAT5 SH2 domain inhibitor. AC-4-130 directly binds to STAT5 and disrupts STAT5 activation, dimerization, nuclear translocation, and STAT5-dependent gene transcription. AC-4-130 induces cell cycle arrest and apoptosis in FLT3-ITD-driven leukemic cells. AC-4-130 has anti-cancer activity and can efficiently block pathological levels of STAT5 activity in acute myeloid leukemia (AML).

STAT5 |
AC-4-130 (0.1-100 μM; 72 hours) leads to a significant increase in apoptosis in a dose-dependent and time-dependent manner in MV4-11 or MOLM-13 cells[1].
?
AC-4-130 (2, 5 μM; 72 hours) induces cell cycle arrest with an increase in G0/G1 arrested cells and a concomitant reduction in cells in S or G2/M[1].
?
AC-4-130 (0.5-2; 24 hours) reveals reduced pY-STAT5 levels both in the cytoplasm and nucleus[1].
?
AC-4-130-mediated STAT5 inhibition efficiently blocks the proliferation and clonogenic growth of primary human AML cells, while healthy CD34+ cells are less sensitive[1].
