Entinostat, also known as SNDX-275 and MS-275, is a benzamide histone deacetylase inhibitor undergoing clinical trials for treatment of various cancers.[1][2][3][4]

Entinostat inhibits class I HDAC1 and HDAC3 with IC50 of 0.51 μM and 1.7 μM, respectively.[5]

Syndax pharmaceuticals currently holds the rights to entinostat and recently received $26.6 million in funds to advance treatments of resistant cancers using epigenetic tools.[6]

It has also been investigated as a potential male contraceptive drug.[7]
