    WO 2013/122953 PCT/US2013/025770 IMIDAZOLIDINE-2,4-DIONE DERIVATIVES AS N-FORMYL PEPTIDE RECEPTOR 2 MODULATORS By inventors: Richard L. Beard, Vidyasagar Vuligonda, John E. Donello, 5 Veena Viswanath and Michael E. Garst RELATED APPLICATION This application claims the benefit of U.S. Provisional Application Serial No. 61/599,522, filed February 16, 2012, the disclosure of which is hereby incorporated 10 in its entirety herein by reference FIELD OF THE INVENTION The present invention relates to novel imidazolidine-2,4-dione derivatives, processes for preparing them, pharmaceutical compositions containing them and 15 their use as pharmaceuticals, as modulators of the N-formyl peptide receptor 2 (FPR2). The invention relates specifically to the use of these compounds and their pharmaceutical compositions to treat disorders associated with the N-formyl peptide receptor 2 modulation. BACKGROUND OF THE INVENTION 20 The N-formyl peptide receptor 2 (FPR2), also known as N-formyl peptide receptor like-1 (FPRL-1), is a G protein-coupled receptor that is expressed on inflammatory cells such as monocytes and neutrophils, as well as in T cells and has been shown to play a critical role in leukocyte trafficking during inflammation and human pathology. FPR2 is an exceptionally promiscuous receptor that responds to a 25 large array of exogenous and endogenous ligands, including Serum amyloid A (SAA), chemokine variant sCKp8-1, the neuroprotective peptide, anti-inflammatory eicosanoid lipoxin A4 (LXA4) and glucocotricoid-modulated protein annexin Al. FPR2 transduces anti-inflammatory effects of LXA4 in many systems, but it can also mediate the pro-inflammatory signaling cascade of peptides such as SAA. The ability 30 of the receptor to mediate two opposite effects is proposed to be a result of different receptor domains used by different agonists (Parmentier, Marc et al. Cytokine & Growth Factor Reviews 17 (2006) 501-519). 1 WO 2013/122953 PCT/US2013/025770 Activation of FPR2 by lipoxin A4 or its analogs and by Annexin I protein has been shown to result in anti-inflammatory activity by promoting active resolution of inflammation which involves inhibition of polymorphonuclear neutrophils (PMNs) and eosinophils migration and also stimulate monocyte migration enabling clearance of 5 apoptotic cells from the site of inflammation in a nonphlogistic manner. In addition, FPR2 has been shown to inhibit NK cytotoxicity and promote activation of T cells which further contributes to down regulation of tissue damaging inflammatory signals. FPR2/ LXA4 interaction has been shown to be beneficial in experimental models of ischemia reperfusion, angiogenesis, dermal inflammation, chemotherapy 10 induced alopecia, ocular inflammation such as but not limited to: endotoxin-induced uveitis, corneal wound healing, re-epithelialization. FPR2 thus represents an important novel pro-resolutionary molecular target for the development of new therapeutic agents in diseases with excessive inflammatory responses. SUMMARY OF THE INVENTION 15 A group of novel imidazolidine-2,4-dione derivatives which are potent and selective FPR2 modulators has been discovered. As such, the compounds described herein are useful in treating a wide variety of disorders associated with modulation of FPR2 receptor.
