AIMS: To design and synthesize novel N-(1-phenyl-2, 3-dihydroxypropyl) arachidonylamides and evaluate their analgesic and anti-inflammatory potential. MAIN METHODS: The murine macrophage cell line RAW 264.7 has been widely used as a model for inflammatory responses in vitro. Our model consists of cultured monolayers of RAW 264.7 cells in which media concentrations of 15-deoxy-Δ13, 14-PGJ2 (PGJ) are measured ...
