ps423

PS423 is a substrate-selective protein kinase PDK1 inhibitor that acts by binding to the PIF-pocket allosteric docking site.

PS210 is a potent and selective activator of PDK1 (Kd: 3 μM), specifically targeting the PIF-binding pocket of PDK1 without affecting other protein kinases such as S6K, PKB Akt, or GSK3. Its prodrug, PS423, serves as a substrate-selective inhibitor of PDK1 in cells, inhibiting the phosphorylation and activation of S6K.
