Both SzV-1287 and LJP-1207 significantly reduced CFA- and K/BxN serum-evoked mechanical hyperalgesia and joint swelling, as well as K/BxN serum-induced macroscopic clinical sings and plasma extravasation. K/BxN serum-evoked neutrophil MPO-activity was attenuated only by LJP-1207, CFA-induced histopathological destruction by SzV-1287. K/BxN serum-induced joint function impairment, CFA-evoked neutrophil MPO-activity and plasma extravasation were not affected by either treatment (↓: significantly reduced; Ø: not affected; n.a.: not analysed).
