Biological Activity

Description SBI-0206965 is a highly selective autophagy kinase ULK1 inhibitor with IC50 of 108 nM, about 7-fold selectivity over ULK2. SBI-0206965 inhibits autophagy and enhances apoptosis in human glioblastoma and lung cancer cells.
Targets
ULK1 [1]
(Cell-free assay)		 ULK2 [1]
(Cell-free assay)
108 nM 711 nM
In vitro

In HEK293T transfected with WT or KI Myc-tagged ULK1 and WT Vps34, SBI-0206965 inhibits Ser249 phosphorylation of overexpressed Vps34 and Beclin1 Ser15 phosphorylation. SBI-0206965 suppresses autophagy induced by mTOR inhibition in A549 cells, and prevents ULK1-dependent cell survival in WT MEFs. In addition, SBI-0206965 also synergizes with mTOR inhibition to induce cancer cell death. [1]

Protocol (from reference)

Kinase Assay:

[1]
  • ULK1 kinase assays

    γ-32P-ATP assays to measure ULK1 kinase activity are performed. Briefly, Flag-ULK1 is transfected into HEK-293T cells and 20 hours later treated as indicated. The immmunoprecipitate is washed in IP buffer 3 times, and washed in kinase buffer (25 mM MOPS, pH 7.5, 1 mM EGTA, 0.1 mM Na3VO4, 15 mM MgCl2,). Hot and cold ATP are added at a 100 μM final concentration. As substrates, GST or the recombinant protein GST-Atg101 purified from E. coli were used at 1 μg for each reaction. Reactions are boiled and run out on SDS-PAGE gels. Gels are dried and imaged using PhosphoImager software.
