Biological target:
DS-437 is a dual PRMT5/7 inhibitor (IC50s of PRMT5/7=6 μM).
In vitro activity:
Using available structures of PRMT5, this study designed DS-437, a PRMT5 inhibitor with an IC50 value of 6 μM against both PRMT5 and PRMT7 that is inactive against 29 other human protein-, DNA-, and RNA-methyltransferases and inhibits symmetrical dimethylation of PRMT5 substrates in cells. Reference: ACS Med Chem Lett. 2015 Mar 2;6(4):408-12. https://pubmed.ncbi.nlm.nih.gov/25893041/
In vivo activity:
By contrast, a PRMT7 inhibitor (DS-437) reduced mNaV1.9 currents in Scn11a+/+ mice. DS-437 significantly inhibited the action potential frequency of DRG neurons and relieved pain hypersensitivity in Scn11aA796G/A796G mice.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.

Preparing Stock Solutions

The following data is based on the product molecular weight 397.45 Batch specific molecular weights may vary from batch to batch due to the degree of hydration, which will affect the solvent volumes required to prepare stock solutions.
