Atg4B-IN-3
Atg4B-IN-3 is a ATG4B inhibitor with a Kd value of 18.01 nM against the human target. Atg4B-IN-3 stably regulates the closed conformation of the loop, prevents substrates from accessing the catalytic site Cys74, and thereby inhibits the proteolytic activity of ATG4B. Atg4B-IN-3 blocks autophagic flux, reduces LC3-II levels, promotes p62 accumulation, disrupts autophagy homeostasis and enhances cell death. Atg4B-IN-3 inhibits cell proliferation, migration and clonogenic survival capacity. Atg4B-IN-3 can be used in studies related to esophageal squamous cell carcinoma.

ATG4B 18.01 nM (Kd) |
Atg4B-IN-3 (2.5-10 μM; 24 h) inhibits EBSS-induced autophagy in ECA-109 and TE-1 ESCC cells, as shown by reduced LC3 puncta formation, restored p62 levels, and decreased LC3-II conversion[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:ECA-109; TE-1
-
Concentration:2.5 μM, 5 μM, 10 μM
-
Incubation Time:24 h
-
Result:Did not significantly alter ATG4B protein levels, increased p62 accumulation, and decreased LC3-II levels in a concentration-dependent manner.
Atg4B-IN-3 (5-20 mg/kg; i.p.; once every two days) dose-dependently inhibits hematogenous metastasis of esophageal squamous cell carcinoma in BALB/c nude mice, as evidenced by reduced systemic tumor burden, decreased number of lung metastatic foci, and downregulated expression levels of epithelial-mesenchymal transition markers N-cadherin and MMP-2[1].
