clk-1-in-1

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

DCLK1-IN-1 是选择性的、体内相容的双皮质素样激酶1（DCLK1）激酶结构域化学探针，也是一种高选择性的 DCLK1 2 抑制剂，通过结合和激酶测定IC50值分别为9.5 57.2 nM（DCLK1） 和 31 103 nM（DCLK2）。它具有低毒性，用于研究 DCLK1 生物学并确定其在癌症中的作用。

CLK1 2-IN-3(Cpd-3) 是一种具有高效性和选择性的 CLK1 和 CLK2 抑制剂，抗增殖活性，抑制 CLK1、CLK2、SRPK1、SRPK2、SRPK3 的 的活性。CLK1 2-IN-3 可诱导核斑点扩大，可诱导S6K pre-mRNA选择性剪接和随后抑制多种癌细胞类型细胞生长。

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

Ipivivint, a first-in-class, orally active and potent CDC-like kinase (CLK) inhibitor, inhibits CLK1 (IC50=1.4 μM), CLK2 (IC50=0.002 μM) and CLK3 (IC50=0.022 μM). Ipivivint reduces Wnt pathway signaling gene expression through inhibiting CLK activity and serine and arginine rich splicing factor (SRSF) phosphorylation and disrupting spliceosome activity. Ipivivint can be used for the research of cancer[1]. Ipivivint (SW480 cells; 0.01~10 μM; 1 hour) potently inhibits SRSF5 6 phosphorylation[1].Ipivivint (SW480 cells; 0.03 μM~3 μM; 48 hour) induced apoptosis[1]..Ipivivint (HEK-293T cells; 0.03 μM~3 μM; 1 hour) inhibits Wnt β-catenin signaling induced by Wnt3a[1].Ipivivint (SW480 cells; 0.3~10 μM; 6 hour) increases nuclear speckle enlargement[1].Ipivivint (SW480 cells; 0.3~3μM; 24hours) significantly decreases expression of Wnt target genes (AXIN2, LEF1, MYC, and TCF7) and TCF7L2. SM08502 (SW480 cells; 0.03~3μM; 24hours) inhibits cytoplasmic or nuclear fractions protein expression. Ipivivint (NCI-N87 cells) inhibits proliferation[1].Ipivivint strongly inhibits Wnt pathway signaling activity (EC50 = 0.046 μM) in SW480 colon cancer cells[1]. Ipivivint (25 mg kg; p.o.) potently inhibits tumor SRSF6 phosphorylation[1]. [1]. Tam BY, et al.

Potent and selective CLK inhibitor (IC50 values are 28, 88 and 510 nM for CLK4, 1 and 2, respectively). Exhibits no significant activity at CLK3, DYRK, CDK or GSK3 at a concentration of 10 μM. Inhibits growth of a range of cancer cell lines in vitro at subnanomolar concentrations. Walter et al (2018) Molecular structures of cdc2-like kinases in complex with a new inhibitor chemotype.
