KH CB19 is a potent and selective inhibitor of CLK1 and CLK4 with IC50 values of 19.7 and 530 nM for CLK1 and CLK3, respectively [1] [2].
The cdc2-like kinases (CLKs) are dual specificity protein kinases that phosphorylate the serine- and arginine-rich (SR) proteins, which are involved in regulating the alternative pre-mRNA splicing process [1].
KH CB19 is a potent and selective inhibitor of CLK1 and CLK4. In endothelial cells, KH CB19 inhibited the phosphorylation of serine- and arginine-rich (SR) proteins stimulated by TNF-α and decreased the mRNA expression of tissue factor splice variants [1]. KH CB19 bound to the ATP binding site in CLK3 and CLK1. In enzyme kinetic assays, KH CB19 inhibited DYRK1A with IC50 value of 55.2 nM. In human microvascular endothelial cells (HMEC-1), KH-CB19 (10 µM) reduced the phosphorylation of SRp75, SRp55 and SRp20. However, in TNF-α stimulated HMEC-1, KH-CB19 (10 µM) inhibited the phosphorylation of SRp75, SRp55, SRp40, SC35, SF2/ASF and SRp20. In HMEC-1, KH CB19 (10 µM) significantly reduced the expression of the membrane bound full-length tissue factor (flTF) as well as the soluble asHTF in TNF-α-induced and TNF-α-non-induced cells [2].

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
