S1092 KU-55933 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 results in a significant decrease of autophagy.

S8597 LYN-1604 LYN-1604 is a potential ULK1 agonist with IC50 of 1.66 μM against MDA-MB-231 cells and it binds to wild-type ULK1 with a binding affinity in the nanomole range (Kd=291.4 nM). The ULK1 (Y89A) mutant protein caused a sharp decrease in binding affinity with lower response and Kd than wild-type ULK1, ULK1 (K50A) and ULK1 (L53A) mutants.
