Description



BACKGROUND OF THE INVENTION

The present invention relates to novel piperidinone compounds, which are formyl peptide 2 (FPR2) receptor agonists and/or formyl peptide 1 (FPR1) receptor agonists, 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.

Formyl peptide receptor 2 (FPR2) belongs to small group of seven-transmembrane domain, G protein-coupled receptors that are expressed mainly by mammalian phagocytic leukocytes and are known to be important in host defense and inflammation. FPR2 shares significant sequence homology with FPR1 and FPR3. Collectively, these receptors bind large number of structurally diverse group of agonists, including N-formyl and nonformyl peptides which act as chemo attractants and activate phagocytes. The endogenous anti-inflammatory peptide Annexin A1 and its N-terminal fragments also bind human FPR1 and FPR2. Importantly, anti-inflammatory eicosanoid lipoxin A4, which belongs to newly discovered class of small pro-resolution mediators (SPMs), has been identified as an agonist for FPR2 (Ye R D., et al., Pharmacol. Rev., 2009, 61, 119-61).

Endogenous FPR2 pro-resolution ligands, such as lipoxin A.sub.4 and Annexin A1 trigger a wide array of cytoplasmatic cascades such as Gi coupling, Ca.sup.2+ mobilization and .quadrature.-arrestin recruitment via FPR2. Activation of FPR2 by lipoxin A.sub.4 modifies the effects of peptidic agonists, such as serum amyloid A (SAA), and has alternative effects on phosphorylation pathways depending on the cell type. Lipoxins regulate components of both innate and adaptive immune systems including neutrophils, macrophages, T-, and B-cells. In neutrophils, lipoxins modulate their movement, cytotoxicity and life span. In macrophages, lipoxins prevent their apoptosis and enhance efferocytosis. In most inflammatory cells, lipoxins also down-regulate expression of several pro-inflammatory cytokines, such as IL-6, IL-1.quadrature. and IL-8 as well as up-regulate expression of anti-inflammatory cytokine IL-10 (Chandrasekharan J A, Sharma-Walia N., J. Inflamm. Res., 2015, 8, 181-92). The primary effects of lipoxin on neutrophils and macrophages are termination of inflammation and initiation of resolution of inflammation. The latter is primarily responsible for enhancing anti-fibrotic wound healing and returning of the injured tissue to homeostasis (Romano M., et al., Eur. J. Pharmacol., 2015, 5, 49-63).

Chronic inflammation is part of the pathway of pathogenesis of many human diseases and stimulation of resolution pathways with FPR2 agonists may have both protective and reparative effects. Ischaemia-reperfusion (I/R) injury is a common feature of several diseases associated with high morbidity and mortality, such as myocardial infarction and stroke. Non-productive wound healing associated with cardiomyocyte death and pathological remodeling resulting from ischemia-reperfusion injury leads to scar formation, fibrosis, and progressive lost of heart function. 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). In addition, 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 F N., Trends Pharmacol. Sci., 2010, 31, 266-76) and I/R induced spinal cord injury (Liu Z Q., et al., Int. J. Clin. Exp. Med., 2015, 8, 12826-33).

In addition to beneficial effects of targeting the FPR2 with novel pro-resolution agonists for treatment of I/R induced injury therapeutic, utility of these ligands can also be applied to other diseases. In the cardiovascular system both the FPR2 receptor and its pro-resolution agonists were found to be responsible for atherogenic-plaque stabilization and healing (Petri M H., et al., Cardiovasc. Res., 2015, 105, 65-74; and Fredman G., et al., Sci. Trans. Med., 2015, 7(275); 275ra20). FPR2 agonists also have been shown to be beneficial in preclinical models of chronic inflammatory human diseases, including: infectious diseases, psoriasis, dermatitis, occular 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. J. Pharmacol., 2015, 5, 49-63, Perrett, M., et al., Trends in Pharm. Sci., 2015, 36, 737-755).

Biological Methods

N-formyl peptide receptors (FPRs) are a family of chemo attractant receptors that facilitate leukocyte response during inflammation. FPRs belong to the seven-transmembrane G protein-coupled receptor superfamily and are linked to inhibitory G-proteins (Gi). Three family members (FPR1, FPR2 and FPR3) have been identified in humans and are predominantly found in myeloid cells with varied distribution and have also been reported in multiple organs and tissues. After agonist binding, the FPRs activate a multitude of physiological pathways, such as intra cellular signaling transduction, Ca2+ mobilization and transcription. The family interacts with a diverse set of ligands that includes proteins, polypeptides and fatty acid metabolites which activate both pro-inflammatory and pro-resolution downstream responses.

The FPR2 receptor binds multiple ligands to invoke both inflammatory and anti-inflammatory responses. Inflammation mediator release by FPR2 is promoted by endogenous protein ligands such as Serum amyloid A (SAA) and Amyloid .quadrature. (1-42), whereas resolution of inflammation is induced by ligands that include arachidonic acid metabolites, lipoxin A4 (LXA4) and Epi-lipoxin (ATL), and a docosahexenoic acid metabolite, resolvin D1 (RvD1). The pro-resolving fatty acid metabolites mediate inhibition and resolution of inflammation through the FPR2 receptor by stimulating phagocytosis of apototic neutrophils by macrophages. Removal of the apototic neutrophils induces the release of cytokines that activate pro-resolution pathways.

The FPR1 receptor was originally isolated as a high affinity receptor for N-Formylmethionine containing peptides, such as N-Formylmethionine-leucyl-phenylalanine (FMLP). The protein directs mammalian phagocytic and blood leukocyte cells to sites of invading pathogens or inflamed tissues and activates these cells to kill pathogens or to remove cellular debris.

FPR2 and FPR1 Cyclic Adenosine Monophosphate (cAMP) Assays. A mixture of forskolin (5 .mu.M final for FPR2 or 10 .mu.M final for FPR1) and IBMX (200 .mu.M final) were added to 384-well Proxiplates (Perkin-Elmer) pre-dotted with test compounds in DMSO (1% final) at final concentrations in the range of 1.7 nM to 100 .mu.M. Chinese Hamster Ovary cells (CHO) overexpressing human FPR1 or human FPR2 receptors were cultured in F-12 (Ham's) medium supplemented with 10% qualified FBS, 250 .mu.g/ml zeocin and 300 .mu.g/ml hygromycin (Life Technologies). Reactions were initiated by adding 2,000 human FPR2 cells per well or 4,000 human FPR1 cells per well in Dulbecco's PBS (with calcium and magnesium) (Life Technologies) supplemented with 0.1% BSA (Perkin-Elmer). The reaction mixtures were incubated for 30 min at room temperature. The level of intracellular cAMP was determined using the HTRF HiRange cAMP assay reagent kit (Cisbio) according to manufacturer's instruction. Solutions of cryptate conjugated anti-cAMP and d2 flurorophore-labelled cAMP were made in a supplied lysis buffer separately. Upon completion of the reaction, the cells were lysed with equal volume of the d2-cAMP solution and anti-cAMP solution. After a 1-h room temperature incubation, time-resolved fluorescence intensity was measured using the Envision (Perkin-Elmer) at 400 nm excitation and dual emission at 590 nm and 665 nm. A calibration curve was constructed with an external cAMP standard at concentrations ranging from 1 .mu.M to 0.1 pM by plotting the fluorescent intensity ratio from 665 nm emission to the intensity from the 590 nm emission against cAMP concentrations. The potency and activity of a compound to inhibit cAMP production was then determined by fitting to a 4-parametric logistic equation from a plot of cAMP level versus compound concentrations.
