  Discovery of Potent Cytotoxic Ortho-Aryl Chalcones as New Scaffold Targeting Tubulin and Mitosis with Affinity-Based Fluorescence

  摘要：

  A series of new ortho-aryl chalcones have been designed and synthesized. Many of these compounds were found to exhibit significant antiproliferation activity toward a panel of cancer cell lines. Selected compounds show potent cytotoxicity against several drug resistant cell lines including paclitaxel (Taxol) resistant human ovarian carcinoma cells, vincristine resistant human ileocecum carcinoma cells, and doxorubicin resistant human breast carcinoma cells. Further investigation revealed that active analogues could inhibit the microtubule polymerization by binding to colchicine site and thus induce multipolar mitosis, G2/M phase arrest, and apoptosis of cancer cells. Furthermore, affinity-based fluorescence enhancement was observed during the binding of active compounds with tubulin, which greatly facilitated the determination of tubulin binding site of the compounds. Finally, selected compound 26 was found to exhibit obvious in vivo antitumor activity in A549 tumor xenografts model. Our systematic studies implied a new scaffold targeting tubulin and mitosis for novel antitumor drug discovery.

• Palladium-Catalyzed Annulation of Arynes by <i>o</i>-Halobenzamides: Synthesis of Phenanthridinones
  作者：Chun Lu、Anton V. Dubrovskiy、Richard C. Larock

  DOI：10.1021/jo3016192

  日期：2012.10.5

  The palladium-catalyzed annulation of arynes by substituted o-halobenzamides produces N-substituted phenanthridinones in good yields. This methodology provides this important heterocyclic ring system in a single step by simultaneous C–C and C–N bond formation, under relatively mild reaction conditions, and tolerates a variety of functional groups.

• Efficient Synthesis of a (Z)-3-Methyleneisoindolin-1-one Library Using Cu(OAc)2•H2O/DBU under Microwave Irradiation

  日期：——

  Microwave-promoted efficient synthesis of a (Z)-3-methyleneisoindolin-1-one library from 2-bromobenzamides and terminal alkynes using Cu(OAc)2•H2O/DBU is described. Various benzamide substituents, ring substitutions, including heteroaryl, aryl acetylenes and aliphatic alkynes, could be applied to afford the desired products in good to moderate yield with high stereoselectivity. It is noteworthy that DBU maybe play a dual role as not only the base, but also as a ligand for copper. The reaction is catalyzed by the complex of Cu(OAc)2•H2O and DBU without other additives.

  The domino reaction of o‐bromobenzamides 1 a–m in the presence of K2CO3 and the [PdCl2(PPh3)2] catalyst granted a selective access to phenanthridinones 2 or to the new 1‐carboxamide phenanthridinones 3 depending on the solvent, DMF or 1,4‐dioxane, respectively. Investigations of the reaction parameters provided the first example of a direct correlation between the base dissociation and the solvent

  邻溴苯甲酰胺1 a – m在K 2 CO 3和[PdCl 2（PPh 3）2 ]催化剂的存在下的多米诺反应允许选择性地利用菲啶酮2或新的1-羧酰胺菲啶酮3，具体取决于分别是DMF或1,4-二恶烷。对反应参数的研究为碱解离和溶剂极性与所观察到的选择性之间的直接相关提供了第一个例子。此外，机理研究（NMR光谱和ESI-MS监测）使我们能够表征Pd II palladacycle4和联芳基物质是这两个多米诺骨牌工艺的常见中间体。在此基础上，可以设想通过在Pd II palladacycle 4中氧化添加1后生成Pd IV络合物来形成C（sp 2）C（sp 2）键，这一原理得到DFT计算的支持。提出了一般的催化循环来解释这些观察结果。

  CuI/L-proline catalyzed coupling of 2-bromobenzamides and terminal alkynes in PrOH (or DMF and DMSO) at 85-110 degrees C and subsequent additive cyclization produces substituted 3-methyleneisoindolin-1-ones. Variation of N-substituents, aromatic ring, and methylene part is possible by using suitable starting materials.
