    streamlined total syntheses of natural tubulysins such as V (Tb45) and U (Tb46) and pretubulysin D (PTb-D43), and their application to the synthesis of designed tubulysin analogues (Tb44, PTb-D42, PTb-D47-PTb-D49, and Tb50-Tb120), are described. Cytotoxicity evaluation of the synthesized compounds against certain cancer cell lines revealed a number of novel analogues with exceptional potencies [e.g., Tb111:

To find structurally simpler pretubulysin analogs, a series of 2-(3-(methylamino)propyl)thiazole-4-carboxamides are designed and synthesized, and their anticancer activities are screened using MCF-7 (breast cancer), and NCI-H157
    Pretubulysin 是微管溶素的生物合成前体,在多种肿瘤细胞系中显示出强大的生物活性。尽管已有多种微管溶素和预微管溶素全合成路线的报道,但由于结构复杂,商业化仍受到阻碍。为了寻找结构更简单的预管溶素类似物,设计并合成了一系列 2-(3-(甲基基)丙基)噻唑-4-甲酰胺,并使用 MCF-7(乳腺癌)和 NCI-H157 筛选了它们的抗癌活性。肺癌)细胞系紫杉醇 (IC 50  = 0.01 µM) 和 pretubulysin 用作对照。化合物8c (IC 50  = 0.05 µM, MCF-7; 0.09 µM, NCI-H157) 和8h (IC 50 = 0.01 µM,MCF-7;0.02 µM, NCI-H157) 表现出与紫杉醇相当的某些抗肿瘤活性。Pretubulysin 的尿素类似物可能是进一步开发新型抗肿瘤药物的有前途的支架。

  • Pretubulysin derived probes as novel tools for monitoring the microtubule network via activity-based protein profiling and fluorescence microscopy

    Microtubules (mt) are highly dynamic polymers composed of alpha- and beta-tubulin monomers that are present in all dividing and non-dividing cells. A broad variety of natural products exists that are known to interfere with the microtubule network, by either stabilizing or de-stabilizing these rope-like polymers. Among those tubulysins represent a new and potent class of cytostatic tetrapeptides originating from myxobacteria. Early studies suggested that tubulysins interact with the eukaryotic cytoskeleton by inhibition of tubulin polymerization with EC50 values in the picomolar range. Recently, pretubulysins have been described to retain the high tubulin-degradation activity of their more complex tubulysin relatives and represent an easier synthetic target with an efficient synthesis already in place. Although tubulin has been suggested as the dedicated target of tubulysin a comprehensive molecular target analysis of pretubulysin in the context of the whole proteome has not been carried out so far. Here we utilize synthetic chemistry to develop two pretubulysin photoaffinity probes which were applied in cellular activity-based protein profiling and imaging studies in order to unravel and visualize dedicated targets. Our results clearly show a remarkable selectivity of pretubulysin for beta-tubulin which we independently confirmed by a mass-spectrometry based proteomic profiling platform as well as by tubulin antibody based co-staining on intact cells.
    微管(mt)是由α-和β-微管蛋白单体组成的高动态聚合物,存在于所有分裂和非分裂细胞中。已知有多种天然产品可以通过稳定或降低这些绳状聚合物的稳定性来干扰微管网络。其中,管胞素(tubulysins)是一类新型、强效的细胞抑制四肽,源自粘杆菌。早期研究表明,tubulysins 通过抑制微管蛋白聚合与真核细胞骨架相互作用,其 EC50 值在皮摩尔范围内。最近,前管胞素(pretubulysins)被描述为保留了其更复杂的管胞素近亲的高管胞素降解活性,并且是一种更容易合成的目标,其高效合成已经到位。尽管管蛋白被认为是管胞素的专用靶标,但迄今为止还没有在整个蛋白质组的背景下对前管胞素进行过全面的分子靶标分析。在此,我们利用合成化学方法开发了两种pretubulysin光亲和探针,并将其应用于基于细胞活性的蛋白质分析和成像研究,以揭示和观察专用靶标。我们的研究结果清楚地表明,pretubulysin 对 beta-tubulin(β-微管蛋白)具有显著的选择性,这一点我们已通过基于质谱分析的蛋白质组学分析平台以及基于微管蛋白抗体的完整细胞共染色得到了独立证实。
