WH-4-023 is a potent and selective Lck and Src inhibitor (IC50 values are 2 and 6 nM respectively). Exhibits >300-fold selectivity against p38α and KDR. Also potently inhibits SIK (IC50 values are 10, 22 and 60 nM for SIK 1, 2 and 3 respectively) and displays selectivity over a range of closely related kinases. Supports self-renewal of naive hESCs in combination with PD 0325901, CHIR 99021 and SB 590885.
