CHIR-98014 (CT98014) is a selective GSK3 inhibitor; potentiate insulin activation of glucose transport and utilization in vitro and in vivo.

CHIR98014 is a reversible, cell-permeable inhibitor of GSK3α and GSK3β (IC50s: 0.65 and 0.58 nM). Through its effects on GSK3, CHIR98014 stimulates glycogen synthase in cells (EC50: 106 nM), potentiates insulin-dependent glucose transport in isolated musc

CHIR 98024 is a potent GSK-3α/β inhibitor with IC50 of 0.65 nM/0.58 nM in cell-free assays, with the ability to distinguish GSK-3 from its closest homologs Cdc2 and ERK2.
