Glaziovianin A (1) is a novel isoflavone derivative isolated from the leaves of the Brazilian tree Astelia glazioviana. Glaziovianin A (1) showed cytotoxic activity and was suggested to be an inhibitor of tubulin polymerization. We achieved the total synthesis of glaziovianin A (1) by using the Suzuki–Miyaura coupling as a key step.
Glaziovianin A (1) 是一种从巴西树 Astelia glazioviana 的叶子中分离出来的新型异黄酮衍生物。 Glaziovianin A (1) 显示出细胞毒活性,被认为是微管蛋白聚合的抑制剂。我们以 Suzuki-Miyaura 偶联为关键步骤,实现了 Glaziovianin A (1) 的全合成。
Practical Synthesis of Glaziovianin A, a Cytotoxic Isoflavone, and Its <i>O</i><sup>7</sup>-Propargyl Analogue
Glaziovianin A and its O7-propargyl analogue are potent cytotoxic isoflavones. We found that the O7-propargyl analogue completely arrested cell-cycle progression. We have achieved the large-scale synthesis of glaziovianin A and its O7-propargyl analogue for further in vivo experimentation.
