The synthesis of 9-(4-chlorophenyl)-7,7-dimethyl-5(Z), 8-nonadienoic acid (7) and its methyl ester 6, and their effects on arachidonic acid metabolism in vitro are described. The IC50 values of 19.6 and 20.6 microM were observed for inhibition of leukotriene synthesis in human granulocytes for 6 and 7, respectively. Additionally, the compounds inhibited thromboxane B2 (TxB2) synthesis, with respective
描述了9-(4-氯苯基)-7,7-二甲基-5(Z),8-壬二烯酸(7)及其甲酯6的合成及其对花生四烯酸代谢的影响。观察到IC6值分别为19.6和20.6 microM,对人粒细胞中白三烯合成的抑制作用分别为6和7。此外,这些化合物抑制血栓烷B2(TxB2)的合成,其IC50值分别为6.1和20 microM,同时在人单核细胞中PGE2合成产生明显的3-8倍增加。PGE 2合成增加可能反映了花生四烯酸代谢的血栓烷合成酶和内过氧化物E异构酶分支点处游离的花生四烯酸底物分流。
