KU-55933 is a potent and specific ATM inhibitor with IC50/Ki of 12.9 nM/2.2 nM in cell-free assays, and is highly selective for ATM as compared to DNA-PK, PI3K/PI4K, ATR and mTOR. KU‑55933 (ATM Kinase Inhibitor) inhibits the activation of autophagy‑initiating kinase ULK1 and ...
KU-55933 is a cell-permeable ATP-competitive inhibitor of ATM (IC50 = 13 nM; Ki = 2.2 nM) with selectivity over other PIKK family kinases (IC50 = 2.5, 9.3, 16.6 μM for DNAPK, mTOR, PI 3-K, respectively; IC50 > 100 μM for PI 4-K and ATR). Buy ATM/ATR in
