AG-024322 (AG024322) is a novel, potent and ATP-competitive pan-CDK inhibitor with anticancer effects. It is effective against cell cycle kinases CDK1, CDK2, and CDK4 with Ki values in the 1-3 nM range. AG-024322 displays broad-spectrum anti-tumor activity and induces cell apoptosis.

ln Vitro |
At concentrations below 3 μM, AG-024322 (0.1-30 μM; 24 hours) is less hazardous. The ATP concentration of human PBMC is used to determine their vitality, and the TC50 value of these cells is 1.4 μM [2]. On HCT-116 cells, AG-024322 (0-120 nM) inhibits cell proliferation. With an IC50 of 120 nM in functional cellular tests, it is marginally less powerful [2].

ln Vivo |
AG-024322 (IV; 2, 6, and 10 mg/kg; 5 days) had a mean plasma AUC (0-24.5) of 2.11 gh/mL and no side effects at 2 mg/kg. produces lymphocyte depletion and whole-blood bone marrow cytopenia at 6 mg/kg. Additionally, at 10 mg/kg, tubular degeneration was caused by vascular injury at the injection site [1]. Established human tumor xenografts are inhibited in growth by AG-024322 (20 mg/kg) by 32% to 86.4% tumor growth inhibition (TGI). It also demonstrates anticancer effects that are dose-dependent [3]. The MV522 tumor model showed 65% TGI caused by AG-024322 (20 mg/kg). At half the maximum tolerable dosage (MTD), it produced 52% TGI, and at 1/4 of the MTD, it just slightly exhibited antitumor activity [3].

Additional Infomation |
AG-024322 has been used in trials studying the treatment of Neoplasms and Lymphoma, Non-Hodgkin.
CDK1/2/4 Inhibitor AG-024322 is a cyclin-dependent kinase (CDK) inhibitor with antineoplastic activity. AG-024322 selectively inhibits cyclin-dependent kinases (particularly CDK1,2 and 4), enzymes that regulate cell cycle progression. Inhibition of CDK may result in cell cycle arrest, induction of apoptosis, and inhibition of DNA replication and tumor cell proliferation. |

Solubility (In Vitro) |

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.97 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 (5.97 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
