白三烯(leukotrienes,LTs)是七十年代末发现的一类重要的花生四烯酸(arachidonic acid,AA)代谢产物。有极强的生物活性。其中自三烯B_1(LTB_4)通过诱导白细胞聚集、改变血管通透性、降低痛阈等,参与痛风、类风湿性关节炎等疾病,是重要的炎症介质。但已有的抗炎药,如
Leukotrienes (LTs) are an important class of arachidonic acid (AA) metabolites discovered in the late seventies. Have a very strong biological activity. Among them, triene B_1 (LTB_4) is an important inflammatory mediator by inducing leukocyte accumulation, changing vascular permeability, reducing pain threshold, and participating in diseases such as gout and rheumatoid arthritis. But there are anti-inflammatory drugs, such as
