DS-437
Based on 1 publication(s) in Google Scholar
DS-437 is a dual PRMT5/7 inhibitor (IC50s of PRMT5/7=6 μM). DS-437 is selective for PRMT5 and PRMT7 over 29 other human protein-, DNA-, and RNA-methyltransferases. DS-437 is a S-adenosylmethionine (SAM)-competitive inhibitor of PRMT5. DS-437 also inhibits DNMT3A and DNMT3B, with IC50s of 52 and 62 μM, respectively. DS-437 inhibits the methylation of FOXP3.

DS-437 was able to inhibit methylation of an H4[1–24] peptide by the PRMT5–MEP50 complex under balanced conditions (cofactor and substrate concentrations set at their respective Km values) in a dose-dependent manner with an IC50 of 5.9 ± 1.4 μM[1].
DS-437 increased total CD8+ and CD8+ PD-1+ T cells[2].

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: ≥ 2.08 mg/mL (5.23 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 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 (5.23 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.
