An efficient and functional group tolerant route to access hydroxy 1,8-naphthalimides has been used to synthesise a range of mono- and disubstituted hydroxy-1,8-naphthalimides with fluorescence emissions covering the visible spectrum. The dialkoxy substituted compounds prepared possess high quantum yields (up to 0.95) and long fluorescent lifetimes (up to 14 ns). The method has been used to generate
一种有效的且具有官能团耐受性的途径可接近羟基1,8-萘二甲酰亚胺,以合成一系列单和双取代的羟基-1,8-萘二甲酰亚胺,且荧光发射覆盖可见光谱。制备的二烷氧基取代的化合物具有高量子产率(高达0.95)和长荧光寿命(高达14 ns)。该方法已被用于生成脚本蛋白类似物,其通过微管蛋白乙酰化测定成功地在体外抑制HDAC6 ,证实这些化合物比tubastatin更有效。
