preserve the exquisite biological activity of acid 1 and offer the opportunity for effective conjugation to cell type-targeting moieties. All analogues had antiproliferative activities in the high picomolar to low nanomolar range and caused apoptosis and mitotic arrest as measured in a high content nuclear morphology assay. The ten synthetic agents described herein spanned a range of almost 4 orders of
我们报告了第二代合成的非常有力的抗有丝分裂剂N 14 -desacetoxytubulysin H(1)以及该铅结构的九个类似物的制备。我们合成工作的重点包括高效的后期功能化,可用于制备新的侧链和主链修饰的类似物。我们还发现了保留酸1精湛生物活性的C末端修饰并提供了与细胞类型靶向部分有效结合的机会。所有类似物均具有高皮摩尔至低纳摩尔范围的抗增殖活性,并导致细胞凋亡和有丝分裂阻滞,如通过高含量核形态学测定所测。本文所述的十种合成剂的生物学活性跨越了几乎四个数量级的范围,并且说明了发现基于天然产物前导物的非常有效的抗增殖化合物的持续潜力。
