Gatsuciclib
Based on 1 publication(s) in Google Scholar
Gatsuciclib (AZD8421) is a selective CDK2 inhibitor (IC50 = 9 nM) as well as achieving CDK family selectivity in cells versus key off-targets (CDK1, CDK4/6, CDK9). Gatsuciclib has no significant kinase inhibition outside the CDK family. Gatsuciclib inhibits cancer cell proliferation by inhibiting pRB phosphorylation, inducing cell cycle arrest in G1/S phase and senescence. Gatsuciclib can be studied in research for breast cancer and ovarian cancer.

In Vitro
Gatsuciclib (AZD8421) inhibits endogenous phospho-substrate at 58nM with >327-fold selectivity over CDK9 phospho-substrate pSer2 of RNAPIl (>19.2 μM)[1].
Gatsuciclib potently inhibites cell proliferation (69nM, OVCAR3), correlates with inhibition of pRB, arrest in G1/S phase of the cell cycle and induction of senescence in a CCNE1 amplified cell line[1].
Gatsuciclib (AZD8421) (Compound CDK2i) (500 nM, 72 h) effectively downregulates p130 in combination with Abemaciclib (HY-16297) (50 nM) in p53KO cells[2].
Gatsuciclib (500 nM, 8 d) blocks cell-cycle re-entry upon drug withdrawal in combination with Abemaciclib in p53KO cells[2].
Gatsuciclib (500 nM, 10 d) enables long-term growth suppression of p53KO cells when combined with Abemaciclib, which is associated with potent induction of SA-β-Gal expression[2].
Gatsuciclib (500 nM, 6 d) suppresses the phosphorylation of both Rb and p130, long-term growth, growth after withdrawal of the drug, and induces SA-β-Gal activity when combined with Abemaciclib in HR+/HER2- p53 mutant primary breast cancer cell line and PD BC line #5[2].

In Vivo
Gatsuciclib shows robust monotherapy activity in a CCNE1 amplified ovarian model OVCAR3 with regressions seen with monotherapy and in combination with Palbociclib (HY-50767)[1].
Gatsuciclib (AZD8421) (100 mg/kg, p.o., 5 d) markedly reduces MKI67, p130 phosphorylation, E2F1, and cyclin A2 levels in combination with Ribociclib (HY-15777) (25 mg/kg) compared to single agents[2].

Solvent & Solubility
In Vitro:
DMSO : 100 mg/mL (226.98 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.67 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.67 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
