  New Indole Tubulin Assembly Inhibitors Cause Stable Arrest of Mitotic Progression, Enhanced Stimulation of Natural Killer Cell Cytotoxic Activity, and Repression of Hedgehog-Dependent Cancer

  摘要：

  We designed 39 new 2-phenylindole derivatives as potential anticancer agents bearing the 3,4,5-trimethoxyphenyl moiety with a sulfur, ketone, or methylene bridging group at position 3 of the indole and with halogen or methoxy substituent(s) at positions 4-7. Compounds 33 and 44 strongly inhibited the growth of the P-glycoprotein-overexpressing multi-drug-resistant cell lines NCI/ADR-RES and Messa/Dx5. At 10 nM, 33 and 44 stimulated the cytotoxic activity of NK cells. At 20-50 nM, 33 and 44 arrested >80% of HeLa cells in the G2/M phase of the cell cycle, with stable arrest of mitotic progression. Cell cycle arrest was followed by cell death. Indoles 33, 44, and 81 showed strong inhibition of the SAG-induced Hedgehog signaling activation in NIH3T3 Shh-Light II cells with IC50 values of 19, 72, and 38 nM, respectively. Compounds of this class potently inhibited tubulin polymerization and cancer cell growth, including stimulation of natural killer cell cytotoxic activity and repression of Hedgehog-dependent cancer.

  chemistry, and therefore, novel and efficient approaches to their synthesis are in high demand. Among indoles, 2‐aryl indoles have been described as privileged scaffolds. Advanced herein is a straightforward, practical, and transition‐metal‐free assembly of 2‐aryl indoles. Simply combining readily available 2‐fluorotoluenes, nitriles, LiN(SiMe3)2, and CsF enables the generation of a diverse array of indoles

  吲哚是药物化学中必不可少的杂环，因此，迫切需要新颖有效的合成方法。在吲哚中，2-芳基吲哚被描述为特权支架。本文的高级内容是一种简单，实用且不含过渡金属的2-芳基吲哚化合物组装方法。简单地将容易获得的2-氟甲苯，腈，LiN（SiMe 3）2和CsF结合起来，就可以生成各种各样的吲哚（38例，产率48-92％）。可将一系列取代基引入吲哚骨架的每个位置（C4至C7，以及C2处的芳基），以提供进一步处理的方法。

  Control over chemo- and regioselectivity is a critical issue in the heterobiaryl synthesis via C–H oxidative coupling. To address this challenge, a strategy to invert the normal polarity of indoles in the heterobiaryl coupling was developed. With N-carboxyindoles as umpoled indoles, an exclusively ortho-selective coupling with phenols has been realized, employing a Brønsted acid- or Cu(I)-catalyst (as

  控制化学选择性和区域选择性是通过C-H 氧化偶联合成杂二芳基的关键问题。为了应对这一挑战，开发了一种在杂二芳基偶联中反转吲哚正常极性的策略。使用Brønsted 酸或 Cu( I )-催化剂（低至 0.01 mol%） ，使用N-羧基吲哚作为 umpoled 吲哚，实现了与酚类的完全邻位选择性偶联。一系列酚类和N-羧基吲哚在环境温度下具有出色的效率和选择性，并且带有氧化还原活性芳基卤化物（-Br和-I）的底物以正交方式平滑耦合。值得注意的是，已经证明了基于手性二磺酰亚胺或 Cu( I )/手性双膦催化体系的阻转选择性杂二芳基偶联的初步例子。该反应被提议通过 S N 2' 取代或 Cu( I )-Cu( III ) 循环发生，分别使用布朗斯台德酸或 Cu( I ) 催化剂。

  A new synthesis of 4-halo-1H-indoles has been developed from easily available 2,3-dihalophenol derivatives. The key steps are Smiles rearrangement and a one-pot or stepwise Sonogashira coupling/NaOH-mediated cyclization. Subsequent functionalization allows access to a wide variety of 2,4- or 2,3,4-regioselectively functionalized indoles.

  一种新的合成方法已经从易得的2,3-二卤苯酚衍生物中开发出4-卤代-1H-吲哚。关键步骤是Smiles重排和一步法或分步的Sonogashira偶联/ NaOH介导的环化。随后的功能化允许获得多种2,4-或2,3,4位置选择性功能化的吲哚。
