In the present study we synthesized new methoxy derivatives of trans 2,3-diaryl-2,3-dihydrobenzofurans, starting from suitable trans 2,3-diaryloxiranes, using regio- and stereoselective nucleophilic oxiranyl ring-opening reactions. The compounds were tested as anti-inflammatories in U937 cells. All compounds showed a significant role in inhibiting the NF-κB pathway and were able to restore normal ROS
在本研究中,我们从合适的反式2,3-二芳基环氧乙烷开始,使用区域和立体选择性亲核环氧乙烷开环反应合成了反式2,3-二芳基-2,3-二氢苯并呋喃的新甲氧基衍生物。这些化合物在 U937 细胞中被测试为抗炎药。所有化合物在抑制 NF-κB 通路方面均显示出重要作用,并且能够在 LPS 激活后恢复正常的 ROS 和 NO 水平。此外,关于 ACLY 的抑制,对映体富集 (50% ee ) 7a 50显示出比外消旋对应物7a rac更强的效力,以及前列腺素 E 2的更高降低 产生,因此表明该途径中存在立体选择性相互作用。
