体外研究 | PMX-53 is a potent CD88 antagonist and inhibits C5a-induced neutrophil myeloperoxidase release and chemotaxis with IC 50 values of 22 nM and 75 nM, respectively. PMX-53 (10 nM) inhibits C5a-induced Ca 2+ mobilization in HMC-1 cells, but at higher concentrations( ≥30 nM) it causes degranulation in LAD2 mast cells, CD34 + cell-derived mast cells, and RBL-2H3 cells stably expressing MrgX2. Replacement of Trp with Ala and Arg with dArg abolishes the ability of PMX-53 to inhibit C5a-induced Ca 2+ mobilization in HMC-1 cells and to cause degranulation in RBL-2H3 cells expressing MrgX2. |
