6-[[2-[[4-(2,4-Dichlorophenyl)-5-(5-methyl-1H-imidazol-2-yl)-2-pyrimidinyl]amino]ethyl]amino]-3-pyridinecarbonitrile Hydrochloride; CHIR 911 Hydrochloride; CT 99021 Hydrochloride

CHIR-99021 is a potent and highly selective inhibitor of glycogen synthase kinase 3 (GSK-3). CHIR-99021 activates glycogen synthesis in CHO-IR cells and in isolated type 1 diabetic rat skeletal muscle. CHIR-99021 has also been shown to induce the reprogramming of murine and human somatic cells into stem cells.
