[No.04-0004] CHIR99021 (2 mg)
The aminopyrimidine CHIR99021 is the most selective inhibitor of glycogen synthase kinase 3 β (GSK-3β) reported to date1,2. Unlike other potent inhibitors of GSK-3, CHIR99201 does not exhibit cross-reactivity against cyclin-dependent kinases (CDKs) and shows a 350-fold selectivity toward GSK-3β compared to CDKs3. Along with the elimination of differentiation-inducing signaling from mitogen-activated protein kinases, using CHIR99021 to block the activity of GSK-3β enables the self-renewal of embryonic stem cells4.
