A stereoselective total synthesis of the cytotoxic natural products tubulysin U, tubulysin V, and its unnatural epimer epi-tubulysin V, is reported. Simplified analogues containing N,N-dimethyl-d-alanine as a replacement for the N-terminal N-Me-pipecolinic acid residue of the tubulysins are also disclosed. Biological evaluation of these natural products and analogues provided key information with regard
报道了细胞毒性天然产物微管溶素 U、微管溶素 V 及其非天然差向异构体表观微管溶素 V 的立体选择性全合成。含简化类似物Ñ,Ñ二甲基d丙氨酸作为N-末端的替代Ñ微管溶素的-Me-2-哌啶酸残基也被公开。这些天然产物和类似物的生物学评价提供了关于抗增殖活性和微管蛋白聚合抑制的结构和立体化学要求的关键信息。
