General description

A cell-permeable aminopyrimidine compound that acts as potent, ATP-competitive, and highly selective GSK-3 inhibitor (IC50 = 10 and 6.7 nM against GSK-3α and GSK-3β, respectively). Exhibits little or no activity toward 46 other enzymes (IC50 >8.8 µM against 20 kinases and Ki ≥5 µM against 23 non-kinase enzymes) and shows only weak binding to 22 pharmacologically relevant receptors (Kd ~4 µM). This compound is orally available and is shown to effectively improve glucose metabolism in both murine and rat type 2 diabetes models in vivo. The solid form of this compound (Cat. No. 361559) is also available.

Mitochondrial metabolism is critical in hematopoietic stem cell maintenance and differentiation. Here, we present a step-by-step protocol to efficiently differentiate human induced pluripotent stem cells into myeloid progenitors by a robust feeder- and serum-free system. Furthermore, we provide a protocol

Wnt/β-Catenin signaling pathway plays an important role in maintaining self-renewal and pluripotency of human and mouse embryonic stem cells (ESCs). Activation of Wnt/β-Catenin signaling pathway by glycogen synthase kinase-3 (GSK3) inhibitor, the Wnt signaling agonist, could maintain the pluripotency of
