Product Description
YKL-5-124 TFA is a specific and irreversible covalent inhibitor of CDK7 with IC50 of 53.5 nM and 9.7 nM for CDK7 and CDK7/Mat1/CycH, respectively. YKL-5-124 TFA is more than 100-fold selective for CDK7 over CDK9 and CDK2 and has no activity against CDK12 and CDK13. YKL-5-124 TFA induces strong cell cycle arrest and inhibits E2F-driven gene expression with little effect on RNA polymerase II phosphorylation status.
Biological Activity I Assay Protocols (From Reference)
Targets
CDK7 53.5 nM (IC50) CDK7/Mat1/CycH 9.7 nM (IC50) CDK2 1300 nM (IC50) CDK9 3020 nM (IC50)
ln Vitro
G1- and G2/M-phase cell numbers rise while S-phase cell numbers decrease in a dose-dependent manner in response to YKL-5-124 (0-2000 nM; 72 hours; HAP1 cells) treatment[1]. ?In a concentration-dependent manner, YKL-5-124 (0-2000 nM; 24 hours; HAP1 WT cells) treatment suppresses the phosphorylation of CDK1 T-loop and, to a lesser extent, CDK2 T-loop[1]. ?The pull-down of CDK7-cyclin H is blocked when cells treated with YKL -5-124 as a competitor at a concentration of roughly 30 nM, but it has no effect on the pull-down of cyclin K-CDK12/13 in HAP1 cells. CDK7-cyclin H binding to bioTHZ1 is reduced by >50% after 30 minutes of treatment with 100 nM YKL-5 -124[1].

Solubility Data
Solubility (In Vitro)
DMSO: ≥ 100 mg/mL (158.82 mM)
H2O: 50 mg/mL (79.41 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (3.97 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.5 mg/mL (3.97 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.


Solubility in Formulation 4: 50 mg/mL (79.41 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box

Instructions to calculate molar mass (molecular weight) of a chemical compound:
  • To calculate molar mass of a chemical compound, please enter the chemical/molecular formula and click the “Calculate’ button.
Definitions of molecular mass, molecular weight, molar mass and molar weight:
  • Molecular mass (or molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
  • Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
