Lipoxins are an important class of pro-resolving mediators that play a crucial role in the resolution of inflammation. Thus, the synthesis of more chemically and metabolically stable synthetic lipoxin analogues is an area of significant interest. Whereas synthetic analogues of lipoxin A4 (LXA4) have been well studied, analogues of lipoxin B4 (LXB4) have been the focus of considerably less attention
脂氧素是一类重要的促消退介质,在炎症消退中发挥着至关重要的作用。因此,合成
化学和代谢更稳定的合成脂氧素类似物是一个令人感兴趣的领域。虽然脂氧素 A 4 (LXA 4 )的合成类似物已得到充分研究,但脂氧素 B 4 (LXB 4 )类似物却受到较少关注。在此,我们报告了 LXB 4模拟物的重点库的不对称合成,其中分子的
三烯核心已被不同的芳香环和杂芳香环取代。这些类似物的合成都是通过通用策略实现的,其中关键步骤是共同上链片段和芳香族下链之间的铃木交叉偶联,然后是立体选择性酮还原。
