SBP-5147
SBP-5147 is an orally active ULK1/ULK2 inhibitor, with an IC50 of 2 nM against ULK1 and an IC50 of 53 nM against ULK2. SBP-5147 inhibits the phosphorylation of Beclin-1 and Vps34, reduces autophagy flux, downregulates the expression of ATG13 and ATG101, upregulates the expression of MHC-I, induces caspase-dependent apoptosis, and decreases the viability of non-small cell lung cancer cells. SBP-5147 is applicable to research related to non-small cell lung cancer[1].

SBP-5147 (Compound 5) binds to intracellular ULK1 in HEK293T cells in NanoBRET assays, with an IC50 of 47 nM[1].
SBP-5147 (10 μM; 1 h) inhibits the phosphorylation levels of ULK1 downstream substrates Beclin-1 (Ser15) and Vps34 (Ser249) by approximately 80% in transfected HEK293T cells[1].
SBP-5147 (10 μM; 18 h) inhibits autophagic flux in A549 cells under nutrient starvation and reduces the population of cells with high autophagic flux[1].
SBP-5147 (72 h) reduces the viability of A549, HCC827, H1373 and H1975 cells, with IC50 values of 91, 49, 40 and 35 nM, respectively[1].
SBP-5147 (1 μM; 8-24 h) induces caspase-dependent apoptosis in A549 cells[1].
SBP-5147 (15-30 nM; 72 h) significantly upregulates the expression of total MHC-I protein in H1373, HCC827 and A549 cells[1].
SBP-5147 potently inhibits ULK1 kinase activity (IC50 = 2 nM) and ULK2 kinase activity (IC50 = 53 nM) in biochemical ADP-Glo assays[2].
SBP-5147 (48 h) induces the degradation of ATG13 in A549 non-small cell lung cancer (NSCLC) cells, with an IC50 of 4.5 μM[2].

Animal Model:C57BL/6J (8-week-old female)[1]
-
Dosage:10 mg/kg
-
Administration:p.o.; single dose
-
Result:Caused progressive, significant decrease in ATG13 and ATG101 protein levels in liver and lung tissues.
Maintained significantly reduced ATG13 and ATG101 levels at 24 hours postdosing (plasma SBP-5147 almost completely eliminated) compared to vehicle-treated samples.
Confirmed statistically significant reductions in both proteins at 4, 8, and 24 hours postdosing relative to vehicle controls.
