UE01
UE01 is an oral, selective small-molecule modulator targeting both ULK1/ERK1/2. UE01 activates hULK1 with an EC50 of 695.30 nM and a KD of 114.3 nM for ULK1; it inhibits hERK1 with an IC50 of 179.90 nM and a KD of 114 nM for ERK1; it shows weak binding to ERK2 with a KD of 2.8 mM. UE01 induces the conformational transition of ULK1 from an inactive to an active state, enhances the phosphorylation of ULK1 Ser317 and mAtg13 Ser355, and reduces the phosphorylation of ULK1 Ser757. UE01 competitively occupies the ATP-binding pocket of ERK1, inhibits ERK1 kinase activity, and reduces the activity of the ERK1/2 signaling pathway. UE01 induces complete autophagy flux and apoptosis, upregulates Atg5, Atg7, LC3-II/LC3-I, Bax, cytochrome C (Cyt c), Cleaved-Caspase 3, Cleaved-PARP1 and E-cadherin, downregulates p62, Bcl-2, MMP-2 and MMP-9, reduces the phosphorylation of Exo70 Ser250, and promotes the proteasome-dependent degradation of Cav-1, thereby inhibiting EMT-related phenotypes and extracellular matrix degradation. UE01 can be used in studies related to triple-negative breast cancer.

UE01 activates human ULK1 with an EC50 of 695.30 nM, and inhibits ERK1 with an IC50 of 179.90 nM; the Kd values of UE01 for ULK1, ERK1 and ERK2 are 114.3 nM, 114 nM and 2.8 mM, respectively[1].
UE01 (20 μM; 6 h) increases the thermal stability and protease degradation resistance of ULK1, ERK1 and ERK2 in MDA-MB-231 cells, induces activation-associated conformational changes in ULK1, and competitively occupies the ATP-binding pocket of ERK1[1].
UE01 inhibits the proliferation of triple-negative breast cancer cells MDA-MB-231 and BT-549, with IC50 values of 21.86 μM and 24.24 μM, respectively[1].
UE01 (10-40 μM; 24 h) upregulates E-cadherin, downregulates MMP-2, MMP-9 and Cav-1, and reduces the phosphorylation level of Exo70 Ser250, thereby inhibiting EMT-related phenotypes and extracellular matrix degradation[1].
UE01 (20 μM; 48 h) significantly inhibits the migration of MDA-MB-231 and BT-549 cells in scratch wound healing assays, with stronger efficacy than single-target controls, and this effect is mediated by activating ULK1 and inhibiting ERK1/2/Exo70[1].
UE01 (20 μM; 48 h) significantly inhibits the migration of MDA-MB-231 cells in Transwell assays, with stronger efficacy than single-target controls, and this effect depends on the expression of ULK1 and ERK1[1].
UE01 (10-40 μM; 24 h) activates the ULK1 signaling pathway and inhibits the ERK1/2 signaling pathway in a concentration-dependent manner, and regulates metastasis-related proteins (upregulates E-cadherin, downregulates Cav-1, MMP-2, MMP-9) in MDA-MB-231 and BT-549 cells. These effects are mediated by the ULK1 and Cav-1/Exo70 pathways[1].
UE01 (20 μM; 24 h) upregulates the expression of E-cadherin and downregulates the expression of MMP-2 in MDA-MB-231 cells, and its downregulatory effect on MMP-2 is stronger than that of the single-target control[1].
UE01 (10-40 μM; 24 h) increases autophagy levels in MDA-MB-231 and BT-549 cells in a concentration-dependent manner, as determined by LC3B fluorescence assay[1].
