ULK1 24.14 nM (EC50) |
ULK1 0.719 μM (Kd) |
BL-918 (compound 33i) binds to ULK1 with a high binding affinity (KD=0.719 μM)[1].
BL-918 (5 μM; for 24 hours) induces autophagy in Neuron-Like SH-SY5Y cells[1].
BL-918 (0.5-50 μM; for 24 hours) can partially reverse MPP+-induced cell death, which is determined by enhancing cell viability[1].
BL-918 (5 μM; for 6-36 hours) time-dependently elevates the expression levels of LC3-II, Beclin-1, and its phosphorylation status, whereas reduces the level of the selective autophagy substrate SQSTM1/p62. BL-918 elevates Ser317 and Ser555 phosphorylation of ULK1, as well as decreases Ser757 phosphorylation of ULK1[1].
