    Cryptophycin-55/52 based antibody-drug conjugates: Synthesis, efficacy, and mode of action studies
    摘要:
    Cryptophycin-52 (CR52), a tubulin inhibitor, exhibits promising antitumor activity in vitro (picomolar level) and in mouse xenograft models. However, the narrow therapeutic window in clinical trials limits its further development. Antibody-drug conjugate (ADC), formed by coupling cytotoxic compound (payload) to an antibody via a linker, can deliver drug to tumor locations in a targeted manner by antibody, enhancing the therapeutic effects and reducing toxic and side effects. In this study, we aim to explore the possibility of CR52-based ADC for tumor targeted therapy. Due to the lack of a coupling site in CR52, its prodrug cryptophycin-55 (CR55) containing a free hydroxyl was synthesized and conjugated to the model antibody trastuzumab (anti-HER2 antibody drug approved by FDA for breast cancer therapy) via the linkers based on Mc-NHS and Mc-Val-Cit-PAB-PNP. The average drug-to-antibody ratios (DARs) of trastuzumab-CR55 conjugates (named T-L1-CR55, T-L2-CR55, and T-L3-CR55) were 3.50, 3.29, and 3.35, respectively. These conjugates exhibited potent cytotoxicity in HER2-positive tumor cell lines with IC50 values at low nanomolar levels (0.58-1.19 nM). Further, they displayed significant antitumor activities at the doses of 10 mg/kg in established ovarian cancer (SKOV3) and gastric cancer (NCI-N87) xenograft models without overt toxicities. Finally, the drug releases were analyzed and the results indicated that T-L3-CR55 was able to effectively release CR55 and further epoxidized to CR52, which may be responsible for its best performance in antitumor activities. In conclusion, our results demonstrated that these conjugates have the potential for tumor targeted therapy, which provides insights to further research the CR55/CR52-based ADC for tumor therapy.

    从天然symplostatin 4支架优化的新型抗癌干细胞化合物可抑制Wnt /β-catenin信号通路
    摘要:
    癌症干细胞(CSC)负责癌变,癌症进展,复发,转移和耐药性。因此,靶向CSCs的药物分子的开发在医学研究领域中起着至关重要的作用。但是,有极少数的分子可以选择性地消融CSC。由于缺乏抗CSC的先导化合物,针对CSC的药物的研究和开发受到限制。在这项研究中,发现了一种抗CSCs铅化合物35b,该化合物衍生自Symplostatin 4的天然化学支架。该化合物在体外和体内均表现出对肿瘤生长的显着抑制作用。此外,35b可以显着减少黑色素瘤肿瘤球的数量,并降低ALDH +黑色素瘤细胞的百分比。进一步的机制研究表明,化合物35b可通过有效阻断Wnt /β-catenin信号传导途径消除黑色素瘤CSC。总的来说,我们的发现将为开发抗CSCs药物提供新颖的化学支架和分子设计的替代思路。

    The convergent total synthesis of cryptophycins C and D is described. It has been shown that in both natural products the absolute configuration of the a-amino acid corresponds to the D-series. The structural assignment for cryptophycin C has been corrected to reflect this fact. Since the structure of cryptophycin A has been correlated to cryptophycin C, the chloro-0-methyltyrosine unit in cryptophycin
    描述了隐霉素 C 和 D 的收敛全合成。已经表明,在两种天然产物中,α-氨基酸的绝对构型对应于 D 系列。已更正了隐藻素 C 的结构分配以反映这一事实。由于隐藻素A的结构与隐藻素C相关,隐藻素A中的氯-0-甲基酪氨酸单元具有D-构型。隐藻素是与陆生蓝绿藻 Nostoc sp. 相关的强效肿瘤选择性细胞毒素。GSV 224' 和 Nostoc sp。ATCC 53789.2 每种藻类中的主要细胞毒素,cryptophycin A,对植入小鼠的实体瘤(包括耐药性肿瘤)显示出极好的活性。超过 20 种相关的细胞毒素作为次要成分存在于 GSV 224 菌株中,以及这些化合物中的一些,例如,隐藻素 B 和 C,已被分离出足够的量用于体内评估。~为了获得足够数量的选定天然存在的隐藻素和合成类似物,用于构效关系 (SAR) 研究、临床前评估和人类临床试验,我们设计了一个通用的合成。正如原始论文中所述,Cryptophycins

    Among the hapalosin derivatives synthesized, the compounds carrying methyl (5a), methylthioethyl (5d) and phenylmethyl (5e) groups at the C12 position possess only the cis-peptide structure, in contrast to the cases of 5b and 5c. In addition to their conformational stability, the biological activities of the compounds were determined in relation of the P-glycoprotein-mediated MDR-reversing activity
    与5b和5c的情况相反,在合成的Hapalosin衍生物中,在C12位置带有甲基(5a),甲硫基乙基(5d)和苯基甲基(5e)的化合物仅具有顺肽结构。除了它们的构象稳定性之外,还根据P-糖蛋白介导的MDR-逆转活性和细胞凋亡的诱导来确定化合物的生物学活性。

    Acyclic and a highly efficient stereoselective CC bond formation of aldehyde3 with the crotylboron reagent4, derived from (−)-α-pinene, provided a homoallylic alcohol6 in ≥99% enantio-(ee) and diastereomeric excess (de). The alcohol6 was linearly converted into the desired Fragment A10 of cryptophycins in seven steps. This enantiomerically pure Fragment A was conveniently and efficiently coupled with

    group chemistry during chain extension. In a subsequent post-modification step, the allyl side chains can be quantitatively modified via free-radical addition of different omega-functional thiols to afford hydrophilic/hydrophobic patterned oligoesters. The proposed synthetic strategy provides an interesting alternative to rapidly generate libraries of foldamers with identical chain length and monomer sequence
    亲水/疏水图案化是一种成熟的设计策略,可指导天然和非天然低聚物和聚合物的二级结构形成。这一贡献探索了一种合成均匀、序列定义、亲水/疏水图案化低聚(α-羟基酸)的新方法的可行性。所提出的策略基于对由疏水性[(2S)-2-羟基-4-甲基戊酸]和掩蔽亲水性[(2S)-2-羟基戊-4-烯酸]交替序列组成的反应性低聚酯支架的后修饰。酸] α-羟基酸。使用 (2S)-2-hydroxypent-4-enoic 酸代替复杂的侧链保护的亲水结构单元避免了在扩链过程中对额外保护基化学的需要。在随后的修改后步骤中,烯丙基侧链可以通过自由基加成不同的 omega 功能硫醇进行定量修饰,以提供亲水/疏水图案化的低聚酯。所提出的合成策略提供了一种有趣的替代方案,可以快速生成具有相同链长和单体序列但侧链功能不同的折叠体库。((C) Wiley-VCH Verlag GmbH & Co.

  • Thioesterase from Cereulide Biosynthesis Is Responsible for Oligomerization and Macrocyclization of a Linear Tetradepsipeptide

    intermediate predicted from canonical activity of CesA and CesB. To differentiate between the mechanisms, both tetradepsipeptides were prepared as N-acetyl cysteamine thioesters (SNAC), and the ability of the purified recombinant terminal CesB thioesterase (CesB TE) to oligomerize and macrocyclize each substrate was probed. Only the canonical substrate is converted to cereulide, ruling out the alternative mechanism
    Cereulide 是一种有毒的环状 depsidodecapeptide,由两种非核糖体肽合成酶 CesA 和 CesB在蜡样芽孢杆菌中产生。虽然在结构上与缬氨霉素高度相似,并具有同源的生物合成基因簇,但最近的工作表明,脑蓝素是通过一种不同的机制产生的,该机制依赖于两个二缩肽-肽基载体蛋白 (PCP) 结合中间体的非规范偶联。最终,这种替代机制产生了一种四肽-PCP 结合中间体,它不同于根据 CesA 和 CesB 的规范活性预测的四肽-PCP 中间体。为了区分机制,将两种四肽制备为N-乙酰半胱胺硫酯 (SNAC),以及纯化的重组末端 CesB 硫酯酶 (CesB TE) 寡聚化和大环化每种底物的能力。只有经典底物被转化为脑脑苷脂,排除了替代机制。结果表明,CesB TE 可以使用相关的四肽底物,如缬氨霉素四肽和混合脑苷脂-缬氨霉素四肽与其天然底物结合产生嵌合天然产物。这项工作阐明了脑苷
