CAS#: 1906920-28-2 (BAY598 R-isomer)

Description: BAY-598 R-isomer is the R-isomer of BAY589. BAY-598 R-isomer may be used as a reference compound. BAY-598 is a potent, peptide-competitive chemical probe for SMYD2. BAY-598 has a unique chemotype relative to the current SMYD2 chemical probe LLY-507. BAY-598 inhibits in vitro methylation of p53K370 with IC50 = 27 nM and has more than 100-fold selectivity over other histone methyltransferases and other non-epigenetic targets. BAY-598 inhibits the methylation of p53K370 in cells with IC50 < 1 µM. (Further to this, BAY-598 has properties that are compatible with in vivo experiments.) A control compound, BAY-369, has also been developed. BAY-369 inhibits the in vitro methylation of p53K370 with IC50 > 70 micromolar.
