Synthesis and insulin-sensitizing activity of a novel kind of benzopyran derivative
摘要:
A series of benzopyran derivatives was synthesized and their insulin-sensitizing activities were evaluated in 3T3-L1 cells. Compounds 6 and 11 exhibited more potent insulin-sensitizing activity than rosiglitazone. (C) 2003 Elsevier Ltd. All rights reserved.

We developed an efficient and environmentally friendly two-step tandem methodology for the synthesis of sugar-containing coumarin derivatives catalyzed by lipozyme TL IM from Thermomyces lanuginosus in continuous-flow microreactors. Compared to those observed for other methods, the salient features of this work including green reaction conditions, short residence time (50 min), and catalysts are more
我们开发了一种高效且环保的两步串联方法,用于在连续流动微反应器中由嗜热霉菌的脂酶 TL IM 催化合成含糖香豆素衍生物。与其他方法相比,该工作的显着特点包括绿色反应条件、停留时间短(50分钟)、催化剂更容易获得、生物催化反应过程高效且易于控制。这种使用连续流动技术的香豆素衍生物的两步串联合成是一个概念证明,它开启了酶促微反应器在香豆素衍生物生物转化中的应用。
