This product has been discontinued.



A cell-permeable N-methylindolyl-enaminonitrile that acts as a potent inhibitor against CLK1, DYRK1A (IC50 = 19.7 and 55.2 nM, respectively), and likely CLK4, while exhibiting much lower potency against CLK3 (IC50 = 0.53 µM) and little activity toward a panel of 71 other protein kinases. Shown to be more effective than TG003 (Cat. No. 219479) in suppressing both basal and TNF-α-stimulated SRp55 and SRp75 phosphorylation, as well as human tissue factor spliced variants, flTF and asHTF, mRNA levels in human microvascular endothelial cells HMEC-1 (5 to 10 µM).

Revision16-April-2012 JSW
Synonyms(E)-Ethyl-3-(2-amino-1-cyanovinyl)-6,7-dichloro-1-methyl-1H-indole-2-carboxylate, Clk Inhibitor IV
DescriptionA cell-permeable N-methylindolyl-enaminonitrile that acts as a more potent inhibitor than TG003 (Cat. No. 219479) against CLK1 activity (IC50 = 19.7 and 48.6 nM, respectively) by targeting the kinase ATP binding site in a non-ATP mimetic fashion. KH-CB19 is also reported to exhibit higher potency than TG003 against DYRK1A (IC50 = 55.2 vs. 156.1 nM, respectively) and CLK3 (IC50 = 0.53 vs. >4 µM, respectively), while exhibiting no activity against a panel of 71 other protein kinases. Thermostability shift assay reveals stronger interaction of KH-CB19 toward CLK4 than CLK1, predicting better or at least comparable potency against CLK4. KH-CB19 is shown to be more effective than TG003 in suppressing both basal and TNF-α-stimulated phosphorylation of serine/arginine rich proteins SRp55 (77.5% vs. 45% inhibition by 5 µM respective inhibitor against stimulated level) and SRp75 (80% vs. 27.5% inhibition by 5 µM respective inhibitor against stimulated level), as well as human tissue factor spliced variants, flTF and asHTF, mRNA levels in human microvascular endothelial cells HMEC-1.
