P21dhydrochloride is a potent and selective breast tumor Ki nase (Brk) inhibitor (IC50 = 30 nM). Exhibits >650-fold selectively for Brk over Aurora B Ki nase and Lck. Downregulates SNAIL protein, restores E-cadherin expression and suppresses migration in breast cancer cells. Also activein vivoand orally bioavailable.
BRK inhibitor P21dhydrochloride is a highly potent inhibitor of breast tumor kinase (BRK PTK6), displaying an IC50 of 30 nM. Additionally, it effectively suppresses p-SAM68 with an IC50 value of 52 nM. This compound, BRK inhibitor P21dhydrochloride, serves as a valuable tool for evaluating the efficacy of BRK inhibitors in xenograft breast tumor models, enabling the assessment of their in vivo activity.
