The invention provides a histone deacetylase fluorescence probe, and a preparation method and applications thereof. The structure formula of the histone deacetylase fluorescence probe is disclosed inthe invention. In synthesis, 6-(dimethylamino)-2-naphthaldehyde with two-photon effect is selected as a dye, so that further nucleophilic reaction is realized after deacetylation reaction, and fluorescence signals are generated; aldehyde group carbon is modified into cyanogroup alcohol structures, hydroxyl is connected with HDACs responsive groups, and the histone deacetylase fluorescence probe isused for detecting and imaging of the activity of histone deacetylase in tissue. According to the histone deacetylase fluorescence probe, cyanogroup with excellent electron-withdrawing capability isintroduced, so that after response of HDACs with the histone deacetylase fluorescence probe, intramolecular cyclization reaction is carried out rapidly, activation of fluorescence signals is realized,detecting and imaging on histone deacetylase in living cells and tissue are realized, and excellent clinical application value is achieved.
