| 摘要 |
The invention describes novel mono-hydroxy, di-hydroxy and tri-hydroxy docosapentaenoic acid (DPA) analogues, their preparation, isolation, identification, purification and uses thereof. Resolution of inflammation is now held to be an active process where autacoids promote homeostasis. Using functional-metabololipidomics and in vivo systems, endogenous n-3 docosapentaenoic (DPA) acid is converted during inflammation-resolution in mice and by human leukocytes to novel n-3 products congenerous to D-series resolvins (Rv), protectins (PD) and maresins (MaR), termed specialized pro-resolving mediators (SPM). The new n-3 DPA structures include 7,8,17-trihydroxy-9,11,13,15E,19Zdocosapentaenoic acid (RvD1n_3 DPA), 7,14-dihydroxy-8,10,12,16Z,19Z-docosapentaenoic acid (MaR1n_3 DPA) and related bioactive products. |
