| Cell experiment [1]: | |
|
Cell lines |
HeLa cells |
|
Preparation method |
Soluble in DMSO >12.5mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
|
Reacting condition |
2μl of 10 mM TG003 dissolved in Me2SO, final concentration at 10μM, 3 days |
|
Applications |
TG003 had a potent inhibitory effect on the activity of Clk1(Cdc2 like kinase1). TG003 inhibited SF2(Splicing factor2) -dependent splicing of β-globin pre-mRNA in vitro by suppression of Clk-mediated phosphorylation. This drug also suppressed serine/arginine-rich protein phosphorylation, dissociation of nuclear speckles, and Clk1-dependent alternative splicing in cells. |
| Animal experiment [2]: | |
|
Animal models |
Seven-week-old, male Jcl:TCR mice |
|
Dosage form |
30mg/kg TG003 suspended in 5% DMSO, 5% Solutol, 9% Tween-80, and 81% saline，subcutaneously injection |
|
Application |
TG003, an inhibitor of CLK1 in mice, could act as a splice-modifying compound for exon-skipping therapy. TG003 promoted skipping of dystrophin exon 31 with the c.4303G > T mutation. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

TG003 is a potent and selective inhibitor of Clk-family kinases with IC50 values of 15, 20, 200 nM and >10 μM for mClk4, 1, 2 and 3, respectively [1]. Also, TG003 is also an inhibitor of casein kinase 1 (CK1) [2].
Cdc2-like kinases (Clks) family consist of Clk1, 2, 3 and 4 and play an important role in mRNA splice site selection. Clks phosphorylate serine/arginine-rich proteins that involved in pre-mRNA processing and release them into the nucleoplasm.
TG003 is a potent and selective Clk-family kinases inhibitor. TG003 competed with ATP with Ki value of 0.01 μM on Clk1/Sty. In HeLa cytosolic S100 extract, TG003 inhibited Clk1/Sty-mediated phosphorylation of SF2/ASF, which played an important role in alternative splicing. Also, TG003 inhibited the splicing of β-globin pre-mRNA when complemented with rSF2/ASF. In HA-Clk1/Sty-overexpressing HeLa cells, TG003 (10 μM) reversibly inhibited phosphorylation of SR proteins and caused HA-Clk1/Sty localized in nuclear speckles [1].
In mice, TG003 inhibited the alteration of splicing site selection induced by Clk1/Sty and affected the alternative splicing of endogenous genes. In X. laevis embryo, TG003 (10μM) rescued the morphological abnormalities in the dorsal ectoderm and mesoderm induced by the overexpression of xClk kinase [1].
