Materials and Methods
[0096] FPR2 agonists would be expected to have significant effects in many different types of dermatological inflammation, but have been exemplified by demonstrating wound healing in a mouse model of punch dermal wound (
[0097] FLIPR: HEK-G16 cells stably expressing the human FPR2 receptor was utilized. Cells were plated into 384-well poly-D-lysine coated plates at a density of 18,000 cells per well one day prior to use. The growth media was DMEM medium supplemented with 10% fetal bovine serum (FBS), 1% antibiotic-antimycotic, 50 g/ml hygromycin, and 400 g/ml geneticin. On the day of the experiment, the cells were washed twice with Hank's Balanced Salt Solution supplemented with 20 mM HEPES (HBSS/hepes buffer). The cells were then dye loaded with 2 M Fluo-4 diluted in the HBSS/Hepes buffer and incubated at 37 C. for 40 minutes. Extracellular dye was removed by washing the cell plates four times prior to placing the plates in the FLIPR (Fluorometric Imaging Plate Reader, Molecular Devices). Ligands were diluted in HBSS/Hepes buffer and prepared in 384-well microplates. Data for Ca.sup.+2 responses were obtained in relative fluorescence units.

[0098] Immunohistochemistry: Fluorescent immunohistochemistry with antibodies specific to FPR2 was used to determine localization in normal human skin. Anti-FPR2 antibody (Abcam) was used at adilution of 1:200 to detect FPR2 protein.
[0099] Dermal wound healing model: Groups of 5ICR male mice weighing 24-28 g were used. During the study, the tested animals were housed in individual cages. Under hexobarbital (90 mg/kg, i.p.) anesthesia, the shoulder and back region of each animal was shaved. A sharp punch (ID 12 mm) was applied to remove the skin including panniculus carnosus and adherent tissues. The wound area, traced onto clear plastic sheets, was measured by use of an ImageProPlus (Media Cybernetics, Version 4.5.0.29) on days 1, 3, 5, 7, 9 and 11. Test substances and vehicle (Placebo, 20 L/mouse) were administered topically (TOP) once daily post skin punch for a total of 10 consecutive days. The positive control of CGS-21680 in 0.5% CMC/PBS, pH 7.4 was given topically as the same regimen. The percent closure of the wound (%) was calculated, and wound half-closure time (CT50) was analyzed by linear regression using Graph-Prism (Graph Software USA). One-way ANOVA followed by Dunnett's test was applied for comparison between the treated and vehicle groups at each measurement time point. Differences are considered significant at P<0.05.
[0100] LL37-induced model of rosacea in mice: Prior to dosing, animals are lightly anaesthetized with isofluorane and baseline right and left ear thickness measurements are made with a digital caliper (Mitutoyo 293-340). At t=1 hrs, animals are lightly anaesthetized with isoflurane to allow topical application (dorsal side) of 10 L of FPR2 agonist formulated in a vehicle consisting of PBS:ethanol (50:50), or vehicle control to both ears. At t=0 hr, mice are re-anaesthetized. Following ear thickness measurements, 20 uL of LL-37 (100 M) is injected into the right ear, while PBS is injected into the left ear. Additional ear thickness measurements are taken at t=3 and 6 hours. After the last time point, mice are euthanized by CO.sub.2 inhalation and ears collected for additional analyses.
[0101] In vitro human skin penetration model: Briefly, split-thickness human abdominal skin (0.50 mm) sections from two donors were mounted in flow-through diffusion cells (PermeGear). FPR2 agonists are applied at a dose of 10 L to a surface area of 0.64 cm.sup.2 (n=7 per compound). PBS is pumped beneath the skin at a constant flow rate of 42 L/min. Receptor fluid samples are collected at 1, 3, 6, 12, and 24 hrs and analyzed by LC/MS/MS.
