Chemical Name: 5-(6-Quinolinylmethylene)-2-[(2-thienylmethyl)amino]-4(5H)-thiazolone

Biological Activity

ATP-competitive, potent cyclin-dependent kinase (cdk) 1 inhibitor (Ki values are 35 and 110 nM for cdk1/cyclin B1 and cdk1/cyclin A respectively). Induces G2/M phase cell cycle arrest and apoptosis. Downregulates the expression of antiapoptotic proteins such as Bcl-2 and survivin and enhances downstream p53 signaling in acute myeloid leukemia (AML).

Technical Data

Soluble to 50 mM in DMSO
>98 %
Store at +4°C
