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

Animal experiment: | 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]. |

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
