生物活性:
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.

体内研究:
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. 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. Animal Model:Nude mice bearing HepG2 tumor xenografts
Dosage:15, 30 mg/kg
Administration:IP; daily; for 4 consecutive weeks
Result:Displayed anti-HCC efficacies, resulting in decreased tumor weights and suppressed tumor growth of HCC cells in nude mice.
Animal Model:Sprague-Dawley rat
Dosage:2 mg/kg for IV; 10 mg/kg for IP (Pharmacokinetic Analysis)
Administration:IV or IP
Result:Had a T1/2 of 2.31 hours, a CL of 26.28 mL/min?kg, and and an AUC of 1269 hr?ng/mL for IV. Had a T1/2 of 2.69 hours, a Cmax of 2033 ng/mL, and an AUC of 5979 hr?ng/mL for IP.

体外研究:
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. XST-14 (20-80 μM; for 24 h) leads a decrease in cell proliferation activity. XST-14 (5 μM; for 24 h) induces apoptosis in HepG2 and human primary HCC cells. XST-14 (5 μM; for 12 h) strongly inhibits the conversion of LC3-I to LC3-II in CHO cells stably expressing GFP-LC3. XST-14 (5 μM; for 12 h) inhibits the Ser249 phosphorylation of PIK3C3 and Ser15 phosphorylation of BECN1.
