The present invention provides novel tubulysin analogues, methods of making and methods of using such analogues and conjugates thereof. The essential features for the potent cytotoxicity of tubulysin D have been established for the first time by the synthesis and evaluation of a series of analogues. By identifying functionality that surprisingly is not necessary for activity, highly potent cell-growth inhibitors have been developed that are smaller and considerably more stable than tubulysin D.
本发明提供了新型的管芽菌素类似物,以及制备和使用这些类似物及其共轭物的方法。通过合成和评估一系列类似物,首次确定了管芽菌素D的强效细胞毒性的基本特征。通过确定出令人惊讶的不必要的活性功能,开发出了比管芽菌素D更小、更稳定的高效细胞生长
抑制剂。
