Cayman BIO

BIO is a cell-permeable bis-indolo (indirubin) compound that acts as a highly potent, selective, reversible, and ATP-competitive inhibitor of GSK3α/β (IC₅₀ = 5 nM). ^1,2 Its specificity has been tested against various cyclin-dependent kinases (CDKs) (IC₅₀s = 83, 300, 320, and 10,000 nM for Cdk5/p25, Cdk2/A, Cdk1/B, and Cdk4/D₁, respectively). BIO was also tested for its specificity towards many other commonly studied kinases (IC₅₀ ≥10 µM), including MAP kinases, PKA, PKC isoforms, PKG, CK, and IRTK. ^1,2 Inhibition of GSK by BIO has been shown to result in the activation of the Wnt signaling pathway and sustained pluripotency in human and mouse embryonic stem cells (ESCs).³ BIO is reported to maintain self-renewal in human and mouse ESCs as well as induce the differentiation of neonatal cardiomyocytes.⁴
