GtoPdb Ligand ID: 7007

Synonyms: BAY 86-5274 | MS-275 | SNDX-275 | ZK 244894
Compound class: Synthetic organic
Comment: Entinostat (MS-275) inhibits Class I histone deacetylases (HDACs 1, 2, 3 & 8), but has been shown to be somewhat selective for HDAC1 [1,4]. Studies in rodent models of inflammation suggest that inhibition by entinostat may be clinically useful [2,6-8], perhaps more so than broader acting Class I HDAC inhibitors such as vorinostat (SAHA) [6].
