 Use of DS-437


DS-437 is a potent, selective, dual inhibitor of PRMT5 and PRMT7 with IC50 of 6.0 uM for both, DS-437 is inactive against 29 other human protein-, DNA-, and RNA-methyltransferases; inhibits methylation of full-length histone 4 by PRMT5-MEP50 with an IC50 of 37 ± 1.2 μM in a biochemical assay; inhibits symmetrical dimethylation of PRMT5 substrates in cells.

In Vitro 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].
In Vivo DS-437 (10 mg/kg; i.p.; 5 times a week) has some beneficial effects on inhibiting tumor growth. The combination of DS-437 and the anti-p185erbB2/neu antibody 4D5 had even more dramatic effects[1]. Animal Model: Six to Ten weeks old female Balb/c mice (bearing  CT26Her2 tumor cells)[1] Dosage: 10 mg/kg Administration: i.p.; 5 times a week Result: Had some beneficial effects on inhibiting tumor growth.
