XST-14 is a potent, competitive and highly selective ULK1 inhibitor with an IC50 of 26.6 nM. XST-14 induces autophagy inhibition by reducing the phosphorylation of the ULK1 downstream substrate. XST-14 induces apoptosis in hepatocellular carcinoma (HCC) cells and has antitumor effects[1].
XST-14 inhibits ULK1 (IC50=13.6 nM), MAP2K1/MEK1 (IC50=721.8 nM), MAPK14/p38 alpha (IC50=283.9 nM), TGFBR2 (IC50=809.3 nM), ACVR1/ALK2 (IC50=183.8 nM), ULK2 (IC50=70.9 nM) and CAMK2A (IC50=66.3 nM) by the 10-point titration results from SelectScreen Kinase Profiling Services[1]. XST-14 (20-80 μM; for 24 h) leads a decrease in cell proliferation activity[1]. XST-14 (5 μM; for 24 h) induces apoptosis in HepG2 and human primary HCC cells[1]. XST-14 (5 μM; for 12 h) strongly inhibits the conversion of LC3-I to LC3-II in CHO cells stably expressing GFP-LC3[1]. XST-14 (5 μM; for 12 h) inhibits the Ser249 phosphorylation of PIK3C3 and Ser15 phosphorylation of BECN1[1].
XST-14 (15, 30 mg/kg/day; IP; for 4 consecutive weeks) displays anti-HCC efficacies, resulting in decreased tumor weights and suppressed tumor growth of HCC cells in nude mice[1]. XST-14 (2 mg/kg for IV; 10 mg/kg for IP) has a T1/2 of 2.31 hours for IV and a T1/2 of 2.69 hours for IP[1]. | [References]
