Biological Activity

TG003 is a potent and ATP-competitive Cdc2-like kinase (Clk) inhibitor with IC50 of 20 nM, 200 nM, and 15 nM for Clk1, Clk2, and Clk4, respectively. No inhibitory effect on Clk3, SRPK1, SRPK2, or PKC.

Cell Experiment
Cell lines HeLa cells and COS-7 cells
Preparation method 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 count the density every 24 h for 3 days. Then fixed the cells with 1 mL of ice-cold 70% ethanol, washed with PBS, incubated in 1 ml of PBS which is 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
Concentrations ~10 μM
Incubation time 3 days
Animal Experiment
Animal models Xenopus laevis embryos
Formulation DMSO
Dosages ~10 μM
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
