An object of the present invention is to provide a compound having a novel structure for overcoming the defects of conventional steroid agents and NSAIDs. It is found that the particular dihydroxy bodies of eicosapentaenoic acid and docosahexaenoic acid, which have not conventionally been known (11,18-dihydoxy eicosapentaenoic acid (11,18-diHEPE), 17,18-dihydroxy eicosapentaenoic acid (17,18-diHEPE) etc.), have activity of inhibiting neutrophil, thereby solving the object. The present invention unexpectedly remarkably inhibits infiltration into a tissue of, and activation of neutrophil found out at acute inflammation. The compound of the present invention is a compound which has not conventionally been known. Therefore, utility as a new therapeutic is provided.
                            本发明的目的是提供一种具有新型结构的化合物,以克服传统类
固醇制剂和非甾体抗炎药的缺陷。本发明发现,传统上未知的二十碳五烯酸和
二十二碳六烯酸的特定二羟基体(11,18-二羟基二十碳五烯酸(11,18-diHEPE)、17,18-二羟基二十碳五烯酸(17,18-diHEPE)等)具有抑制中性粒细胞的活性,从而解决了上述目的。本发明意外地显著抑制了急性炎症时发现的中性粒细胞对组织的浸润和活化。本发明的化合物是一种传统上不为人所知的化合物。因此,本发明可作为一种新疗法使用。
