Biological Activity

Description SGC707 is a potent, selective and cell-active allosteric inhibitor of protein arginine methyltransferase 3 (PRMT3) with IC50 and Kd of 31 nM and 53 nM, respectively.
Targets
PRMT3 [1] PRMT3 [1]
31 nM 53 nM(Kd)
In vitro In cells, SGC707 binds to PRMT3 and reduces PRMT3-dependent H4R3me2a. SGC707 also stabilizes PRMT3 in both HEK293 and A549 cells with EC50 values of 1.3 μM and 1.6 μM, respectively. [1]
In vivo In CD-1 male mice, SGC707 (30 mg/kg, i.p.) gives good plasma exposure over 6 h with the peak plasma level of 38000 nM, which suggests that SGC707 is suitable for animal studies. [1]

Protocol (from reference)

Kinase Assay: [1]
  • PRMT3 biochemical assay

    A radioactivity-based assay is optimized and used to determine the inhibition of PRMT3 in vitro. In a scintillation proximity assay (SPA), tritiated S-adenosylmethionine (3H-SAM) served as a methyl donor to methylate biotinylated histone peptide substrate. After completion of the reaction, the reaction mixture is transferred to the wells of a streptavidin / scintillant-coated microplate. The Biotinylated peptides binding to streptavidin coated resin, brings the incorporated 3H-methyl and the scintillant to close proximity. The amount of methylated peptide is quantified by tracing the radioactivity (counts per minute) as measured by the TopCount NXT™ Microplate Scintillation and Luminescence Counter. Due to the very acidic nature of the 3H-SAM solution, non-tritiated (cold) SAM is used to supplement the reactions. The C-terminally biotinylated peptide composed of the first 24 amino acids residues of histone H4 (H4 1-24) is used as substrate. The typical assay mixture contained 0.01% Tween-20, 5 mM DTT, 20 nM PRMT3, 0.3 µM B-H4 1-24 and 28 µM (5 µM 3H-SAM plus 23 µM cold SAM) SAM in 20 mM Tris-HCl (pH 7.5) and a final volume of 20 µL. The IC50 values are determined at Km concentrations of both substrates by titration of the compound in the reaction mixture in a range between 2000-0.2 nM.
