Biological Activity

Description

48740 RP ((Rac)-RP-55778) is a platelet-activating factor (PAF) antagonist.

IC₅₀ & Target

PAF^[1]

In Vivo

48740 RP ((Rac)-RP-55778) is a platelet-activating factor (PAF) antagonist. In animals treated with 48740 RP only, the number of platelets is increased at a time corresponding to 2 and 4 h after the exposure to lipopolysaccharide (LPS) and the number of eosinophils is also slightly increased. Treatment with 48740 RP in combination with the LPS exposure does not influence the increase in neutrophils seen 2 and 4 h after exposure. At 24 h the increase in the number of neutrophils is about half that in control animals. No effects are found on the LPS-induced increase in number of platelets. In animals pretreated with 48740 RP, there is a significant reduction in capillary permeability^[1].

Protocol

Animal Administration^[1]

Guinea pigs of both sexes weighing 300 to 500 g are used for the determination of free lung cell responses and histopathologic examination. Male hamsters, weighing 100 g, are used for capillary permeability determinations. Guinea pigs are pretreated with an intraperitoneal injection of 48740 RP at 20 mg/kg in saline 1 h before exposure to lipopolysaccharide (LPS) and immediately thereafter. Groups of hamsters (n=6) are treated immediately before aerosol exposure, immediately after, and 3 h afterwards^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
