CHIR99021 is a small-molecule chemical inhibitor of glycogen synthase kinase 3β (GSK3β), and is highly selective, showing nearly thousandfold selectivity against a panel of related and unrelated kinases, with an IC50 = 6.7 nM against human GSK3β and nanomolar IC50 values against rodent GSK3β homologs.
