PFI-2 is a potent and selective inhibitor of SETD7 methyltransferase with IC50 value of 2.0 nM [1].
SET domain containing (lysine methyltransferase) 7 (SETD7) is a protein lysine methyltransferase that acts as monomethyltransferase of lysine 4 on histone H3 (H3K4) and regulates DNA methyltransferase 1 (DNMT1) [1].
PFI-2 is a potent and selective SETD7 methyltransferase inhibitor. (R)-PFI-2 inhibited human SETD7 methyltransferase activity with IC50 value of 2.0 nM. However, (S)-PFI-2 was 500-fold less active with IC50 value of only 1.0 µM. (R)-PFI-2 potently inhibited SETD7 with Morrison Kiapp value of 0.33 nM. (R)-PFI-2 occupied the peptide binding groove and effectively inhibited the binding of SETD7 substrates. In the presence of 20 μM SAM, (R)-PFI-2 bound to SETD7 with KD value of 4.2 nM in a SAM-dependent way. In HEK293 cells, (R)-PFI-2 (10 µM) bound to and stabilized SETD7. In Setd7+/+ murine embryonic fibroblasts (MEFs), (R)-PFI-2 increased nuclear localization of Yes-associated protein (YAP) and the expression of YAP target genes Ctgf, Gli2 and Cdc20 [1].
