GEM144
Based on 1 Customer Validation
GEM144 is a potent and orally active DNA polymerase α (POLA1) and HDAC 11 dual inhibitor. GEM144 induces acetylation of p53, activation of p21, G1/S cell cycle arrest, and apoptosis. GEM144 has significant antitumor activity in human orthotopic malignant pleural mesothelioma xenografts.

HDAC11 8.23 μM (IC50) |
GEM144 (0-10 μM; 24 hours) exhibits antiproliferative activity in tested cancer cell lines with IC50s of 0.26 ~ 2.2 μM[1].
GEM144 (0.1 - 0.4 μM; 24 hours) strongly increases levels of H2AX phosphorylation on Ser 39 (γH2AX), and strongly upregulates p21 expression in a dose-dependent manner[1].
GEM144 (0.26 μM in NCI-H4609, 0.95 μM in A2780 and 1.4 μM in MM473; 72 hours) induced G1/S cell cycle arrest[1].

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.
Please enter the basic information of animal experiments:

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.
