In Vitro | RS 504393 inhibits the MCP-1-induced chemotaxis with an IC50 of 330 nM. RS 504393 treatment suppresses allergen induced β-hexosaminidase release significantly. Without allergen priming, MCP-1 induces mast cell degranulation, which is completely suppressed by RS 504393[4]. |
In Vivo | RS504393 (0.3-3 μg) with CCL2 progressively blocks thermal hyperalgesia dose-dependently in mice[1]. RS 504393 (5 mg/kg, i.v.) supresses the elevated numbers of leukocytes and increased total protein content in BALF induced by The LPS. RS504393 significantly down regulates the LPS-induced elevation of IL-1β, PAI-1 mRNA and protein expressions. RS504393 significantly suppresses induced lung edema, protein-rich fluid, polymorphonuclear accumulation and bronchial wall thickening induced by LPS[2]. RS-504393 significantly reduces renal pathology, especially the extensive interstitial fibrosis mediated by decrease in type I collagen synthesis in a UUO model[3]. |
Kinase Assay | Isolated mast cells are sensitized by incubation with anti-DNP IgE in RPMI1640 containing 10 ng/mL of murine recombinant IL-3, 10 ng/mL of recombinant SCF, and 5% murine serum. The cells are then washed with HBSS containing 10 ng/mL of murine recombinant IL-3, 10 ng/mL of recombinant SCF, 0.04% BSA, and 10 mM HEPES. Resuspended cells at a concentration of 2 to 8×104 cells/100 μL are transferred into triplicate wells of a 96 well U-bottom plate and allowed to equilibrate at 37°C for 10 minutes before the addition of DNP-albumin or compound 48/80. After 45 minutes, the plate is centrifuged at 290 g for 5 minutes at 4°C. The β-hexosaminidase activity of the culture supernatant is determined using a Published protocol. Fifty-μL aliquots of the supernatant are placed in wells of another 96-well plate together with 100 μL of 2.5 mM p-nitrophenyl-N-acetyl β-d glucosaminide solubilized in 0.04mol/Lcitrate buffer adjusted to pH 4.5 with disodium phosphate. After incubation at 37°C for 90 minutes, the reactions are terminated by addition of 50 μL of 0.4mol/Lglycin adjusted to pH 10.7 with sodium hydroxide. The colored product is measured at 405 nm with a reference filter of 570 nm. The relative release of β-hexosaminidase is defined as the activity in the supernatant of the tested cells divided by the activity in the positive control cell supernatant, multiplied by 100. Compound 48/80 stimulus is used for assay control. |
Animal Admin | Male C57BL/6J mice (n=30) and male homozygote CCR1, CCR2 and CCR3 knockout mice (n=12, in each phenotype), 6-8 weeks old and weighing 20±2 g, are anesthetized with a mixture of ketamine (80 mg/kg) and xylazine (30 mg/kg) given intraperitoneally. Intranasal administration of PBS or LPS (5 mg/kg) is performed in a volume of 1 mL/kg body weight. C57BL/6J mice are treated with vehicle or RS504393 (5 mg/kg) intraperitoneally 30 min before LPS challenge. Four hours after LPS challenge, mice are terminated by an intraperitoneal injection of an overdose of pentobarbitone. The mice are kept on a 12-h light/dark cycle with access to mice chow and water ad libitum. |
