clk1/2-in-1

CLK1 2-IN-1 is a CLK1 and CLK2 inhibitor and it also inhibits SRPK1 and SRPK2.

CLK1 2-IN-3 (Cpd-3) is a potent and selective CLK1 and CLK2 inhibitor with antiproliferative activity and inhibits the activities of CLK1, CLK2, SRPK1, SRPK2, and SRPK3.CLK1 2-IN-3 induces nuclear speckle enlargement, which induces S6K pre-mRNA-selective splicing and subsequent inhibition of cell growth of multiple cancer cell types. cancer cell types cell growth.

CLK1-IN-1 is a potent and selective inhibitor of Cdc2-like kinase 1 (CLK1) with an IC50 of 2 nM.

Haspin-IN-2 (compound 4) is a potent and selective inhibitor of haspin, with an IC50 of 50 nM, and also inhibits CLK1 and DYRK1A with IC50 values of 445 nM and 917 nM, respectively [1].

CLK1-IN-2, a metabolically stable Clk1 inhibitor, exhibits selective activity for Clk1 with an IC50 value of 1.7 nM. It is applicable in researching tumor, Duchenne's muscular dystrophy, and viral infections including HIV-1 and influenza.
