Description

General description

A cell-permeable α2-adrenoceptor agonist that lowers protein misfolding in stressed cells (EC₅₀ ~ 400 nM in tunicamycin treated HeLa cells) and acts as a proteostatis regulator. Shown to selectively bind PPP1R15A/GADD34 and disrupt the PPP1R15A-PP1c complex; sustain eIF2α phosphorylation and increase chaperone availability by attenuating translation.

Packaging

Packaged under inert gas

Warning

Toxicity: Standard Handling (A)
