    [0084] These compounds are useful for the treatment of mammals, including humans, with a range of conditions and diseases that are alleviated by the N-formyl peptide receptor like-1 receptor modulation: dermatological inflammation and diseases including, but not limited to, dermal wound healing, hypertrophic scars, keloids, burns, rosacea, atopic dermatitis, acne, psoriasis, seborrheic dermatitis, actinic keratoses, basal cell carcinoma, squamous cell carcinoma, melanoma, viral warts, photoaging, photodamage, melasma, post-inflammatory hyperpigmentation, other disorders of pigmentation, and alopecia (scarring and non-scarring forms).

    [0085] In still another embodiment of the invention, there are provided methods for treating disorders associated with modulation of the FPRL-1 receptor. Such methods can be performed, for example, by administering to a subject in need thereof a therapeutically effective amount of at least one compound of the invention, or any combination thereof, or pharmaceutically acceptable salts, hydrates, solvates, crystal forms and individual isomers, enantiomers, and diastereomers thereof.

    [0086] The actual amount of the compound to be administered in any given case will be determined by a physician taking into account the relevant circumstances, such as the severity of the condition, the age and weight of the patient, the patient's general physical condition, the cause of the condition, and the route of administration.

    [0087] The patient will be administered the compound orally in any acceptable form, such as a tablet, liquid, capsule, powder and the like, or other routes may be desirable or necessary, particularly if the patient suffers from nausea. Such other routes may include, without exception, transdermal, parenteral, subcutaneous, intranasal, via an implant stent, intrathecal, intravitreal, topical to the eye, back to the eye, intramuscular, intravenous, and intrarectal modes of delivery. Additionally, the formulations may be designed to delay release of the active compound over a given period of time, or to carefully control the amount of drug released at a given time during the course of therapy.

    [0088] In another embodiment of the invention, there are provided pharmaceutical compositions including at least one compound of the invention in a pharmaceutically acceptable carrier thereof. The phrase “pharmaceutically acceptable” means the carrier, diluent or excipient must be compatible with the other ingredients of the formulation and not deleterious to the recipient thereof.

    [0089] Pharmaceutical compositions of the present invention can be used in the form of a solid, a solution, an emulsion, a dispersion, a patch, a micelle, a liposome, and the like, wherein the resulting composition contains one or more compounds of the present invention, as an active ingredient, in admixture with an organic or inorganic carrier or excipient suitable for enteral or parenteral applications. Invention compounds may be combined, for example, with the usual non-toxic, pharmaceutically acceptable carriers for tablets, pellets, capsules, suppositories, solutions, emulsions, suspensions, and any other form suitable for use. The carriers which can be used include glucose, lactose, gum acacia, gelatin, mannitol, starch paste, magnesium trisilicate, talc, corn starch, keratin, colloidal silica, potato starch, urea, medium chain length triglycerides, dextrans, and other carriers suitable for use in manufacturing preparations, in solid, semisolid, or liquid form. In addition auxiliary, stabilizing, thickening and coloring agents and perfumes may be used. Invention compounds are included in the pharmaceutical composition in an amount sufficient to produce the desired effect upon the process or disease condition.

    [0090] Pharmaceutical compositions containing invention compounds may be in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixirs. Compositions intended for oral use may be prepared according to any method known in the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents selected from the group consisting of a sweetening agent such as sucrose, lactose, or saccharin, flavoring agents such as peppermint, oil of wintergreen or cherry, coloring agents and preserving agents in order to provide pharmaceutically elegant and palatable preparations. Tablets containing invention compounds in admixture with non-toxic pharmaceutically acceptable excipients may also be manufactured by known methods. The excipients used may be, for example, (1) inert diluents such as calcium carbonate, lactose, calcium phosphate or sodium phosphate; (2) granulating and disintegrating agents such as corn starch, potato starch or alginic acid; (3) binding agents such as gum tragacanth, corn starch, gelatin or acacia, and (4) lubricating agents such as magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate may be employed.

    [0091] In some cases, formulations for oral use may be in the form of hard gelatin capsules wherein the invention compounds are mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin. They may also be in the form of soft gelatin capsules wherein the invention compounds are mixed with water or an oil medium, for example, peanut oil, liquid paraffin or olive oil.

    [0092] Pharmaceutical compositions containing invention compounds may be in a form suitable for topical use, for example, as oily suspensions, as solutions or suspensions in aqueous liquids or nonaqueous liquids, or as oil-in-water or water-in-oil liquid emulsions.

    [0093] The pharmaceutical compositions may be in the form of a sterile injectable suspension. This suspension may be formulated according to known methods using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides, fatty acids (including oleic acid), naturally occurring vegetable oils like sesame oil, coconut oil, peanut oil, cottonseed oil, etc., or synthetic fatty vehicles like ethyl oleate or the like. Buffers, preservatives, antioxidants, and the like can be incorporated as required.

    [0094] The compounds of the invention may also be administered in the form of suppositories for rectal administration of the drug. These compositions may be prepared by mixing the invention compounds with a suitable non-irritating excipient, such as cocoa butter, synthetic glyceride esters of polyethylene glycols, which are solid at ordinary temperatures, but liquefy and/or dissolve in the rectal cavity to release the drug.

    [0095] Since individual subjects may present a wide variation in severity of symptoms and each drug has its unique therapeutic characteristics, the precise mode of administration and dosage employed for each subject is left to the discretion of the practitioner.

    [0096] The compounds and pharmaceutical compositions described herein are useful as medicaments in mammals, including humans, for treatment of diseases and/or alleviations of conditions which are responsive to treatment by agonists or functional antagonists of the N-formyl peptide receptor like-1 (FPRL-1) receptor. Thus, in further embodiments of the invention, there are provided methods for treating a disorder associated with modulation of the N-formyl peptide receptor like-1 (FPRL-1) receptor. Such methods can be performed, for example, by administering to a subject in need thereof a pharmaceutical composition containing a therapeutically effective amount of at least one invention compound. As used herein, the term “therapeutically effective amount” means the amount of the pharmaceutical composition that will elicit the biological or medical response of a subject in need thereof that is being sought by the researcher, veterinarian, medical doctor or other clinician. In some embodiments, the subject in need thereof is a mammal. In some embodiments, the mammal is human.

    Materials and Methods

    [0097] 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 (FIG. 2). Anti-inflammatory activity in this model has been exemplified with the FPR2 agonists described in Table 4.

    [0098] FLIPR: HEK-Gα16 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 μg/ml hygromycin, and 400 μg/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 μM 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.

    [0099] Immunohistochemistry: Fluorescent immunohistochemistry with antibodies specific to FPR2 was used to determine localization in normal human skin. Anti-FPR2 antibody (Abcam) was used at a dilution of 1:200 to detect FPR2 protein.

    [0100] Dermal wound healing model: Groups of 5 ICR 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 Image—ProPlus (Media Cybernetics, Version 4.5.0.29) on days 1, 3, 5, 7, 9 and 11. Test substances and vehicle (Placebo, 20 μL/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.

    [0101] 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 μL 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 μM) 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.

    [0102] 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 μL 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 μL/min. Receptor fluid samples are collected at 1, 3, 6, 12, and 24 hrs and analyzed by LC/MS/MS.
