Chemical Name: (1Z)-1-(3-Ethyl-5-methoxy-2(3H)-benzothiazolylidene)-2-propanone

Biological Activity

Potent, ATP-competitive inhibitor of Clk-family kinases (IC50 values are 15, 20 and 200 nM for mClk4, 1 and 2 respectively and >10 μM for mClk3). Also inhibits DYRK1A/B (IC50 values are 24 and 34 nM respectively). Suppresses serine/arginine-rich protein phosphorylation; affects the regulation of alternative splicing by phosphorylation of SR protein both in vitro and in vivo.

Technical Data

Soluble to 100 mM in DMSO and to 75 mM in ethanol
>98 %
Store at +4°C
