We report novel conformationally locked GFP chromophore amino-derivatives containing indole and indoline moieties. Optical properties of these compounds were studied. The introduction of the indoline group produces a shift in the absorption and emission maxima to the long-wavelength region and stabilizes the quantum yield of fluorescence. The introduce of the indole group leads to a hypsochromic shift and a noticeable decrease of fluorescence intensity.

GFP发色团的构象锁定吲哚和二氢吲哚衍生物的合成和光学性质

我们报告了含有吲哚和二氢吲哚部分的新型构象锁定 GFP 生色团氨基衍生物。研究了这些化合物的光学性质。二氢吲哚基团的引入产生了吸收和发射最大值向长波长区域的偏移,并稳定了荧光的量子产率。吲哚基团的引入导致低色移和荧光强度的显着降低。
