Jusbetonin, an indolo[3,2-b]quinoline alkaloid glycoside originally isolated from Justicia betonica, and its derivatives were synthesized. The key steps in the synthetic strategy were the construction of indolo[3,2-b]quinoline skeleton and efficient coupling with the saccharides, in which the alpha-D-glycopyranosyl bromides were shown to be effective donors. Primary screening showed that all synthesized
兽药Jusbetonin是一种最初从本草中分离得到的吲哚[3,2-b]喹啉生物碱苷,并合成了其衍生物。合成策略中的关键步骤是吲哚[3,2-b]喹啉骨架的构建和与糖类的有效偶联,其中α-D-甘露糖基溴化物被证明是有效的供体。初步筛选显示所有合成的化合物均具有中等的增殖抑制活性。
