  Synthesis of 1-substituted 3-pyridinylmethylidenylindolin-2-ones and 1-substituted 3-quinolinylmethylidenylindolin-2-ones as the enhancers of ATRA-induced differentiation in HL-60 cells

  摘要：

  As part of our continuing search for potential differentiation agents, 1-benzyl-3-(4-pyridinylmethylidenyl)indolin-2-one (14) was selected as lead compound, and its new pyridinyl and quinolinyl analogs were synthesized and evaluated for differentiation-inducing activity toward HL-60 cells. Most of the tested compounds enhanced the ATRA-induced differentiation; among them, 1-(1-phenylethyl)-3-(3-quinolinylmethylidenyl)indolin-2-one (25) was the most promising one. The two isomers, 25Z and 25E; consisting 25 were found to have similar differentiation activity. The combination of 25 with all trans retinoic acid (ATRA) was found to induce complete differentiation of HL-60 cells and arrest the cells in the G0/G1 phase of the cell cycle. Beside its excellent differentiation activity, 25 also exhibited relatively low cytotoxicity toward normal cells. Therefore, compound 25 is recommended as a candidate for further development of novel enhancer of ATRA-induced differentiation in HL-60 cells. (C) 2008 Published by Elsevier Ltd.

  (MeOTf) was found to catalyze the reaction, which revealed the catalytic property of MeOTf. A mechanism was established through experiments as well as DFT calculations wherein the −OH group of alcohols were converted to the corresponding −OMe groups and in situ generated TfOH. The −OMe groups produced underwent TfOH catalyzed −X alkylation (X=O, S) of the heterocycles followed by −X- to −N-alkyl group

  已经开发了一种催化合成策略，结合了两种方案，例如醇的直接亲核取代，然后是X - 到N - 烷基迁移 ( X = O , S ) 以获得N - 官能化苯并恶唑酮、苯并噻唑硫酮、吲哚啉酮、苯并咪唑硫酮和吡啶酮衍生物。发现三氟甲磺酸甲酯 (MeOTf) 可催化该反应，这揭示了 MeOTf 的催化性能。通过实验和 DFT 计算建立了一种机制，其中醇的 -OH 基团原位转化为相应的 -OMe 基团生成 TfOH。产生的 -OMe 基团经历了 TfOH 催化的杂环的 - X烷基化（X = O，S），然后在一个步骤中进行 - X-到 - N-烷基迁移。
