Hodoodo CAT#: H530398

CAS#: 1216665-49-4

Description: APY29, also known as ASC-29, is a IRE1α inhibitor. The accumulation of unfolded proteins under endoplasmic reticulum (ER) stress leads to the activation of the multidomain protein sensor IRE1α as part of the unfolded protein response (UPR). ATP-competitive inhibitors of IRE1α promote dimerization and activation of RNase activity despite blocking kinase autophosphorylation.

Biological target: APY29 inhibits IRE1α autophosphorylation by binding to the ATP-binding pocket with an IC50 of 280 nM.
In vitro activity: To test the hypothesis that IRE1 self-regulates its expression under ER stress through the activity of its kinase domain and subsequent activation of JNK and JNK-dependent transcription, SH-SY5Y cells were pretreated with APY29 before inducing ER stress, and whether IRE1 levels were affected was analyzed (Fig. 6, A and B). In cells treated with APY29 and Tg, IRE1 protein levels were lower compared with cells treated with Tg, demonstrating that ER stress-dependent induction of IRE1 expression was impaired in these cells. There was no IRE1 phosphorylation detectable in APY29-treated cells, indicating effective inhibition of IRE1 kinase. Deficient IRE1 activation was further illustrated by low levels of spliced XBP1 in the APY29-treated cells. c-JUN phosphorylation was reduced in APY29-treated cells compared with Tg only–treated cells, indicating inhibition of JNK and suggesting that IRE1 kinase-dependent phosphorylation was an upstream event.
