| Description: | MJ33 is an active-site-directed, specific, competitive, and reversible phospholipase A2 (PLA2) inhibitor. MJ33 blocks the calcium-independent phospholipase A2 (iPLA2) activity of Prdx6[1]. MJ33 has a critical effect on inflammatory brain damage[2]. |
| In Vivo: | MJ33 (0.5 μM/kg ; by tail vein, at 24 h before MCAO) significantly blocks the increase IL-1β, IL-17 and IL-23 in rats stimulated by Prdx6 siRNA treatment[2]. Compared with the Prdx6 siRNA group, combined exposure to Prdx6 siRNA and MJ33 significantly downregulates the mRNA and protein expression of NF-κB, iNOS and COX-2[2]. Animal Model: Adult male Sprague-Dawley rats weighing 270-310 g (middle cerebral artery occlusion (MCAO) group) [2] Dosage: 0.5 μM/kg Administration: By tail vein, at 24 h before MCAO Result: Significantly blocked the increase IL-1β, IL-17 and IL-23 in rats stimulated by Prdx6 siRNA treatment. |
| In Vitro: | MJ33, a transition-state analog competitive inhibitor of PLA2, inhibits the degradation of dipalmitoylphosphatidylcholine (DPPC) by ∼50% in both the whole lung and isolated alveolar type 2 cells. In vitro measurement of PLA2 activity in homogenate of lungs or isolated type 2 cells is markedly inhibited by MJ33 when assays at pH 4.0 in Ca2+-free medium but has no effect on Ca2+-dependent PLA2 activity at pH 8.5[3]. |
