生物活性

Atg4B-IN-2 is a potent competitive Atg4B inhibitor with Ki value of 3.1 μM, also possesses declining PLA2 inhibitory potency, IC50s of 11 μM and 3.5 μM for Atg4B and PLA2, respectively. Atg4B-IN-2 enhances the anticancer activity of anti-castration-resistant prostate cancer drugs via autophagy inhibition[1].

IC50 & Target

IC50: 11 μM (Atg4B), 3.5 μM (PLA2)[1]
Ki: 3.1 μM (Atg4B)[1]
体外研究
(In Vitro)

Atg4B-IN-2 (compound 21f) (1-10 μM; 2 hours) restores the p62 expression in cells treated with AF (amino acid-free) in a dose-dependent manner[1].
Atg4B-IN-2 (1 and 5 μM; 2 hours) decreases moderately autophagic vesicles at 1 μM, and almost completely inhibits autophagy at 5 μM[1].
Atg4B-IN-2 (5 μM; 2 hours) inhibits Abi-induced autophagy and significantly augments apoptotic cell death and sensitivity to Abi[1].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
