Ceralasertib (AZD6738) is a potent inhibitor of ATR kinase activity with an IC50 of 0.001 μM against the isolated enzyme and 0.074 μM against ATR kinase-dependent CHK1 phosphorylation in cells. Ceralasertib (AZD6738) induces cell death and senescence in non-small cell lung cancer (NSCLC) cell lines. Ceralasertib (AZD6738) impairs viability of four Kras mutant cell lines: H23, H460, A549, and H358. , with the lowest GI50 and greatest maximal inhibition in H460 and H23 cells (1.05 μM, 88.0% and 2.38 μM, 86.2%, respectively). Ceralasertib (AZD6738) potentiates the cytotoxicity of CDDP and NSC 613327 in NSCLC cell lines with intact ATM kinase signaling, and potently synergizes with CDDP in ATM-deficient NSCLC cells[1]. Ceralasertib (AZD6738) inhibits human breast cancer cell lines with IC50 values less than 1 μM using MTT assay. Ceralasertib (AZD6738) induces cell cycle arrest and apoptosis. It downregulates DNA damage response molecules and cell proliferative signaling molecules[2].

ATR inhibitor AZD6738 prevent NCI‐H929 TP53−/− cell growth in NSG mice. NSG mice were subcutaneously injected with 106 NCI‐H929 TP53−/− cells (left panel). After 1 week, mice with detectable tumors were randomly distributed into four groups of seven mice and treated with AZD6738 (25 mg/kg; i.g., 5 times a week for 2 weeks), as indicated by the arrows (middle panel). The graphs represent the tumor volume kinetics (mean±SD, middle panel) and the tumor volume on Day 12 (right panel).

Solvent & Solubility
DMSO : 70 mg/mL (169.69 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, 1 year; -20°C, 6 months. When stored at -80°C, please use it within 1 year. When stored at -20°C, please use it within 6 months.

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
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: ≥ 5 mg/mL (12.12 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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: ≥ 2.08 mg/mL (5.04 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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: 50% PEG300 50% Saline

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Ceralasertib (AZD6738) is dissolved in DMSO at 30 mM and diluted in DMSO to desired working concentrations. The final DMSO concentration in media for all conditions and controls is 0.1% for Ceralasertib (AZD6738) dose response experiments, 0.05% for Ceralasertib (AZD6738) + chemotherapy viability experiments, and 0.025% for all experiments involving 0.3 μM and 1.0 μM doses of Ceralasertib (AZD6738)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Mice[1]
Ceralasertib (AZD6738) is dissolved in DMSO at a concentration of 25 mg/mL or 50 mg/mL and diluted 1:5 in propylene glycol. Ceralasertib (AZD6738) is administered by oral gavage at 25 mg/kg (H23) or 50 mg/kg (H460) for 14 consecutive days. The dosing volume is 10 mL/kg.[1].
