| | HDAC-1 and HDAC-6 Activity Inhibition Experiment |
| Description: | HDAC activity was measured by the Synergy MX Multi-Function Microplate Reader. The compounds were dissolved with DMSO, and transferred to a 384 well test plate using an Echo non-contact nanoscale sonic pipetting system. 15 μl of enzyme (HDAC1/HDAC6, respectively) solvent was added, and incubated at room temperature for 15 minutes, then 10 μl of substrate (trypsin and Ac-peptide) solution was added. Fluorescence intensity signal was read directly on Synergy MX (fluorescence excitation 355 nm, emission fluorescence 460 nm) after cultivated at room temperature for 60 minutes. Fluorescence intensity signal was convented into inhibition rate data (% inhibition rate=(max−fluorescence intensity)/(max−min)*100). The max refers to the fluorescence intensity of the DMSO control, and min refers to the fluorescence intensity of the enzyme-free control. The curve was drawn with the compound concentration and inhibition rate as the horizontal and vertical coordinates, and the curve was fitted with the GraphPad Prism V5.0 Software, and IC50 was calculated. |
