Table 2.

Percentage inhibition of individual HDAC isoforms by 12d, values are the mean of two measurements. IC50 values were determined for HDAC1, HDAC6 and HDAC8. Owing to differences in assay conditions, absolute values are not directly comparable with table 1.

class I isoforms
class IIa isoforms
class IIb and IV isoforms
HDAC1 57%, IC50 7.3 µM HDAC4 4% HDAC6 99%, IC50 160 nM
HDAC2 32% HDAC5 23% HDAC10 44%
HDAC3 38% HDAC7 9% HDAC11 10%
HDAC8 90%, IC50 2.1 µM HDAC9 1%
