General description

A cell-permeable quinolinyl thiazolinone compound that acts as a potent and ATP-competitive inhibitor of Cdk1 (Ki = 35 nM and 110 nM for Cdk1/B1 and Cdk1/A, respectively). It affects Cdk2/E, PKCδ, and SGK only at much higher concentrations (Ki = 340, 318, and 497 nM, respectively), and shows little effect against Cdk4/D and six other commonly studied kinases (Ki =2 M). Short-term treatment for up to 20 hrs results in fully reversible G2/M cell cycle arrest, while prolonged treament (>48 hrs) results in apoptotic cell death in proliferating cancer cells, but not in nontumorigenic epithelial cell lines. The solid form of this compound (Cat. No. 217699) is also available.

Lysosomes are membrane-surrounded cytoplasmic organelles filled with a powerful cocktail of hydrolases. Besides degrading cellular constituents inside the lysosomal lumen, lysosomal hydrolases promote tissue remodeling when delivered to the extracellular space and cell death when released to the cytosol.
