The IC50 values of these antibiotics against PAF share same or slightly less order of magnitude in comparison with the relatively IC50 values of some of the most potent PAF receptor-specific antagonists used in several models against sepsis and other diseases, such as WEB2170, BN52021, and rupatadine [18,36,37] (0.009, 0.013, and 0.106 μg/mL in the aggregometer cuvette, respectively). Here, PCLAF is linked to Sepsis.
