TG003

SKU: orb1689653

Description

TG003 is a small molecule inhibitor of Clk1 and Clk4 kinases. It demonstrates anti-proliferative and pro-apoptotic effects in cancer cell studies and is also a valuable research tool for investigating splicing-related diseases such as Duchenne muscular dystrophy in cellular models.

• Target: CDK
• Solubility: 10% DMSO+40% PEG300+5% Tween 80+45% Saline:4 mg/mL (16.04 mM);DMSO:100 mg/mL (401.07 mM)

Bioactivity

• Target IC50:
  CLK1/Sty:15–20 nM|CLK2:200 nM|CLK4:15–20 nM
• In Vivo:
  Intrathecal injection of either TG003 (1-100 pM) or IC261 (0.1-1 nM) dose-dependently reduces mechanical allodynia and thermal hyperalgesia induced by carrageenan or CFA.
• In Vitro:
  The small drug TG003 increases endogenous expression of p53β and p53γ protein isoforms by modulation of TP53 intron 9 alternative splicing. TG003 exhibits the most potent effect on Clk1/Sty and Clk4 (IC50, 15–20 nM) with lesser effect on Clk2 (IC50=200 nM). TG003 inhibits SF2/ASF-dependent splicing of β-globin pre-mRNA in vitro by suppression of Clk-mediated phosphorylation.
