Picrasidine I has antiosteoclastogenic effect by inhibiting inflammation induced activation of MAPKs, NF-κB and ROS generation followed by suppressing the gene expression of c-Fos and NFATc1 in osteoclast precursors.
12(S)-HpETE(12-羟基二十碳四烯酸)是花生四烯酸在12-脂氧合酶(12-LOX)作用下生成的过氧化代谢产物。能剂量依赖性地刺激细胞内Ca2+释放(效用低于12-HETE),还能通过其对内皮细胞的作用参与血管张力的调节,诱导血管平滑肌细胞c-Fos和c-Jun蛋白的表达,增加AP-1( activating protein 1)的活性。
