Synthetic investigations of ustiloxin natural products are described. The first total synthesis of ustiloxin F was completed in 15 steps via ethynyl aziridine ring-opening by a phenol derivative. The results of biological tests of synthetic ustiloxins D and F, and two analogs, O-Me-ustiloxin D and 6-Ile-ustiloxin, demonstrated that the free hydroxyl group ortho to the ether linkage is critical for
描述了对ustiloxin天然产物的合成研究。ustiloxin F的第一个全合成反应是通过苯乙炔衍生物通过乙炔基氮丙啶开环在15个步骤中完成的。合成的金属毒蛋白D和F以及两个类似物O-Me-ustiloxin D和6-Ile-ustiloxin的生物学测试结果表明,与醚键邻位的游离羟基对于活性和Val / V的变化至关重要。 Ala位点在生物学活性上产生变化,表明需要在该位点进一步扰动以更广泛地研究微管蛋白的结合。
