TG 003

Pricing Availability Delivery Time Qty
Cat.No. 4336 - TG 003 | C13H15NO2S | CAS No. 719277-26-6
Description: Potent inhibitor of Clk-family kinases; also inhibits DYRK1A/B
Chemical Name: (1Z)-1-(3-Ethyl-5-methoxy-2(3H)-benzothiazolylidene)-2-propanone
Purity: ≥98% (HPLC)

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.
