Definitions

• the present invention relates to novel pyrrolidinone compounds of formula I which are formyl peptide 2 (FPR2) receptor agonists, and also relates to compositions containing them, and methods of using them, for example, for the treatment of atherosclerosis, heart failure, chronic obstructive pulmonary disease (COPD), and related diseases.
• FPR2 formyl peptide 2

• Formyl peptide receptor 2 belongs to a small group of seven- transmembrane domain, G protein-coupled receptors that are expressed in multiple human tissues including immune cells and are known to be important in host defense and inflammation. FPR2 shares significant sequence homology with FPR1 and FPR3 (Journal of Autoimmunity 85, 2017, 64-77). Collectively, these receptors bind a number of structurally diverse agonists, including N-formyl and non-formyl peptides which act as chemo attractants and activate phagocytes. The endogenous peptide Annexin A1 and its N-terminal fragments are examples of ligands that bind human FPR1 and FPR2.
• Fatty acids such as the eicosanoid lipoxin A4, which belongs to a class of small pro-resolution mediators (SPMs), has also been reported as an agonist for FPR2 (Ye RD., et al., Pharmacol. Rev., 2009, 61, 119-61).
• SPMs small pro-resolution mediators
• FPR2 pro-resolution ligands such as lipoxin A 4 and Annexin Al
• Endogenous FPR2 pro-resolution ligands have been reported to trigger a wide array of cytoplasmatic cascades such as Gi coupling, Ca 2+ mobilization and b-arrestin recruitment.
• FPR2 regulates both innate and adaptive immune systems including neutrophils, macrophages, T-, and B-cells.
• neutrophils FPR2 ligands modulate movement, cytotoxicity and life span.
• agonism of FPR2 prevents apoptosis and enhances efferocytosis.
• Ischemia-reperfusion (I/R) injury is a common feature of several diseases associated with high morbidity and mortality, such as myocardial infarction and stroke.
• FPR2 modulation is proposed to enhance myocardial wound healing post injury and diminish adverse myocardial remodeling (Kain V., et al., J. Mol. Cell. Cardiol., 2015, 84, 24-35).
• FPR2 pro-resolution agonists in the central nervous system, may be useful therapeutics for the treatment of a variety of clinical I/R conditions, including stroke in brain (Gavins FN., Trends Pharmacol.

• FPR2 agonists also have been shown to be beneficial in preclinical models of chronic inflammatory human diseases, including: infectious diseases, psoriasis, dermatitis, inflammatory bowel syndrome, Crohn’s disease, ocular inflammation, sepsis, pain, metabolic/diabetes diseases, cancer, COPD, asthma and allergic diseases, cystic fibrosis, acute lung injury and fibrosis, rheumatoid arthritis and other joint diseases, Alzheimer's disease, kidney fibrosis, and organ transplantation (Romano M., et al., Eur.
