Product Description
GP-82996 (CINK-4) is a selective CDK4/6 pharmacological inhibitor. The IC50 values of GP-82996 for CDK4/cyclin D1, CDK6/cyclin D1, and Cdk5/p35 are 1.5, 5.6, and 25 μM, in that order. GP-82996 can be applied to cancer research.
Biological Activity I Assay Protocols (From Reference)
Targets
Cdk4/cyclin D1 (IC50 = 1.5 μM); CDK6/cyclinD1 (IC50 = 5.6 μM); CDK5/p35 (IC50 = 25 μM); CDK2/cyclinA (IC50 >50 μM); CDK1/cyclinB (IC50 >100 μM); CDK2/cyclin E (IC50 >50 μM); CDK4/cyclin D2 (IC50 >50 μM); Cdk6/cyclin D2 (IC50 >50 μM); V-abl (IC50 >10 μM); c-met (IC50 >10 μM); IGF-1R (IC50 >10 μM); Insulin-R (IC50 >10 μM)
ln Vitro
GP-82996 (5, 10 μM; 24 hours) causes an increase in the G0-G1/S ratio and G1 arrest in p16 positive (MRC-5) and p16 negative (U2OS) cells[1].GP-82996 (5, 10 μM; 24 hours) decreases pRb hyperphosphorylation, but does not alter CDK4 levels in MRC-5 and U2OS cells[1]. GP-82996 (5, 10 μM; 48 hours) causes 83% of U2OS cells to undergo apoptosis when exposed to a concentration of 10μM[1]. GP-82996 (0.1–40 μM; 24, 48, and 72 hours) inhibits A549, H358, SKLU-1, H23, and PC14 cells' ability to proliferate; at 72 hours, the IC50 values are 4–7 μM[2]. GP-82996 (3, 5, 10 μM; 48 hours) causes H23 and A549 cells to go into G1 arrest[2]. GP-82996 ((1, 3, 5, 10 μM; 72 hours) increases the sensitivity of Paclitaxel in lung cancer cells (A549, SKLU-1, H23 cells) harboring KRAS mutations [2]. GP-82996 (10 μM; 72 hours) increases the apoptosis of A549 and H23 cells when combined with Paclitaxel (3 nM; 72 hours)[2].
ln Vivo
GP-82996 (30 mg/kg, intraperitoneal for 29 days) in mouse xenograft models results in a reduced final tumor volume when compared to vehicle control[1].

Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 2.1902 mL 10.9510 mL 21.9020 mL
5 mM 0.4380 mL 2.1902 mL 4.3804 mL
10 mM 0.2190 mL 1.0951 mL 2.1902 mL

*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
