TG 003 (CAS 719277-26-6): R&D Systems
Catalog Number: 4336
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.
