mPGES1 respectively, play pivotal roles in augmenting inflammatory responses. PGE2 is known to participate in cancer pathological processes as well. Isocoumarins are natural compounds with a wide range of biological activities. In this study, 3-aryl isocoumarin derivatives are synthesized and tested against 5-LOX enzyme in vitro and PGE2 production in HeLa cells. Most of the compounds show high activity
5-LOX和mPGES1分别在花生四烯酸途径之一中的白三烯和另一途径中的PGE 2的生物合成在增强炎症反应中起关键作用。已知PGE 2也参与癌症病理过程。异香豆素是具有广泛生物活性的天然化合物。在这项研究中,合成了3-芳基异香豆素衍生物,并针对HeLa细胞中的5-LOX酶和体外PGE 2产生进行了测试。大多数化合物显示出高活性,并且1c被鉴定为双重抑制剂,针对5-LOX和PGE 2的IC 50为4.6±0.26μM和6.3±0.13μM。分别生产。另一种化合物7f对5-LOX的IC 50为12.4±0.14μM。进一步的研究表明1c和7f对抗5-LOX的作用机理是混杂的和竞争性的作用方式。Thunberginol A(7c)对PGE 2的生产表现出的IC 50为15.8±0.03μM 。1c和7c抑制mPGES1和COX-2的mRNA表达。这项研究确定了一种具有双重抑制活性的新型支架1c,
