Description

Biochem/physiol Actions

Potent and selective ULK1 inhibitor that sensitizes cancer cells to nutrient stress by suppressing autophagy induction and autophagic flux.

ULK-101 is a potent and selective ULK1 inhibitor (ULK1/2 IC50 = 8.3/30 nM) that inhibits ULK1-dependent cellular Beclin 1 phosphorylation (pSer15 IC50 = 390 nM) with greater kinome selectivity (4 off-target hits using a 327-kinase panel) and potency than SBI-0206965 (IC50 = 38 nM/cell-free ULK1 kinase assay, 2.4 μM/cellular Beclion 1 pSer15). ULK-101 sensitizes cells to nutrient stress in U2OS (EC50 = 6.3 μM vs. 22.3 μM with full media) and in KRAS mutant lung cancer cultures (full media/nutrient withdrawal EC50 ratio >5) by suppressing autophagy induction and autophagic flux.
