(E/Z)-TG003

mCLK4:15 nM|mCLK1:20 nM|mCLK2:200 nM

TG003通过抑制IL-1β异核RNA的剪接阻断血小板产生IL-1β RNA。在3T3-L1脂肪细胞分化过程中,TG003也阻断PKCβII的可变剪接和PPARγ1和PPARγ2的表达。TG003通过抑制Clk1/Sty介导的磷酸化抑制人类β珠蛋白在体外的SF2/ASF依赖性剪接。TG003抑制哺乳动物细胞中Clk1/Sty激酶活性,而对10 μM浓度的HeLa和COS-7细胞的生长没有毒性作用。

10 μM TG003能够治疗非洲爪蟾体内过度Clk活性诱导的胚胎缺陷.

Ethanol:<1 mg/mL,DMSO:6 mg/mL (24.06 mM),warmed

2 × 105 HeLa cells or 1.5 × 105 COS-7 cells resuspended in 2 mL of medium are plated on 6-well dishes, and 2 μL of 10 mM TG003 dissolved in Me2SO (final concentration at 10 μM), or 2 μL of Me2SO, is added to some wells. Cells are trypsinized, and the density is counted every 24 h for 3 days. Cells are then fixed with 1 mL of ice-cold 70% ethanol, washed with PBS, incubated in 1 ml of PBS containing 1 μg/mL DNase-free RNase A and 50 μg/mL propidium iodide for 20 min at 37 °C, and proceeded to cell cycle analysis by FACSCalibur.(Only for Reference)
