the key step in the synthesis of tetrahydropyran derivatives. A phenotypic screen led to the identification of compounds that inhibit mitosis (as seen by the accumulation of round cells with condensed DNA and membrane blebs; see picture). These compounds were termed tubulexins as they target the CSE1L protein and the vinca alkaloid binding site of tubulin.
聚合物结合的醛与均丙醇之间的Prins环化反应是合成四氢吡喃衍生物的关键步骤。通过对表型的筛选,可以鉴定出抑制有丝分裂的化合物(如带有浓缩DNA和膜泡的圆形细胞的积累所见;见图)。这些化合物被称为微管毒素,因为它们靶向CSE1L蛋白和微管蛋白的长春花生物碱结合位点。
