NSAH (2-hydroxy-N'-[(E)-(2-hydroxynaphthalen-1-yl)methylidene]benzohydrazide) 是一种可逆竞争性非核苷类的核苷酸还原酶抑制剂，无细胞 IC50 为 32 μM，基于细胞的 IC50 约为 250 nM。

CN-SAH is a potent and selective inhibitor of DOT1L.

Suberoylanilide hydroxamic acid (SAHA) is a class I and class II histone deacetylase (HDAC) inhibitor that binds directly to the catalytic site of the enzyme thereby blocking substrate access. [1] coumarin-Suberoylanilide hydroxamic acid (c-SAHA) is a SAHA derivative where the anilino cap group is replaced by 7-amino-4-methylcoumarin to produce a fluorescent probe that competitively binds HDAC. [2] The fluorescence excitation and emission maxima of free c-SAHA is 325 and 400 nm
