| | In vitro enzymatic HDACs assays |
| Description: | All Examples were tested in HDAC1, 2, 3, 6 and 8 in vitro enzymatic assays. The assay principle is well known (Hauser et al. 2009, Bradner et al. 2010) and all necessary reagents like enzymes, substrates, developer and reference compounds are commercially available (see e.g. BPS Biosciences http://www.bpsbioscience.com/). A series of dilutions of the compounds were prepared with a top concentration of 200 μM (2 μM for HDAC6). The enzymatic reactions were conducted in a mixture containing assay buffer, bovine serum albumin, HDAC substrate, and a test compound. After enzymatic reaction, developer was added and after an additional incubation time, fluorescence intensity was measured at an excitation wavelength of 360 nm and an emission wavelength of 460 nm. A selection of the Examples were tested in a full HDAC panel containing HDAC1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11 in vitro enzymatic assays. The tests were performed as above except that a series of dilutions of the compounds were prepared with a top concentration of 10 μM for all HDACs. |
