The present invention relates to novel oxopyrrolidine urea 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 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 nonformyl 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 eicosanoid, lipoxin A4, which belongs to a class of small pro-resolution mediators (SPMs), has also 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 A4 and Annexin A1, have been reported to trigger a wide array of cytoplasmatic cascades such as Gi coupling, Ca2+ mobilization and β-arrestin recruitment. (Int J Mol Sci. 2013 April; 14(4): 7193-7230). FPR2 regulates both innate and adaptive immune systems including neutrophils, macrophages, T-, and B-cells. In neutrophils, FPR2 ligands modulate movement, cytotoxicity and life span. In macrophages, agonism of FPR2 prevents apoptosis and enhances efferocytosis. (Chandrasekharan J A, Sharma-Walia N,. J. Inflamm. Res., 2015, 8, 181-92). The initiation of resolution of inflammation by FPR2 agonism is 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 loss 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 receptor 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, inflammatory bowel syndrome, Crohn's disease, 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, Ca21 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. FPR2 and FPR1 Cyclic Adenosine Monophosphate (cAMP) Assays were used to measure the activity of the compounds in this patent.
FPR2 and FPR1 Cyclic Adenosine Monophosphate (cAMP) Assays. A mixture of forskolin (5 μM final for FPR2 or 10 μM final for FPR1) and IBMX (200 μM 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 0.020 nM to 100 μM. 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 μg/ml zeocin and 300 μg/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 μM to 0.1 μM 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.
The examples disclosed below were tested in the FPR2 and FPR1 cAMP assay described above and found having FPR2 and/or FPR1 agonist activity. Table 1 below lists EC50 values in the FPR2 and FPR1 cAMP assays measured for the following examples.
The compounds of the present invention may be administered to mammals, preferably humans, for the treatment of a variety of conditions and disorders including atherosclerosis, heart failure, lung diseases including asthma, COPD, and cystic fibrosis; neuroinflammatory diseases including multiple sclerosis, Alzheimer's disease, and stroke; and chronic inflammatory diseases such as inflammatory bowel disease, rheumatoid arthritis, psoriasis, sepsis, and kidney fibrosis.
Unless otherwise specified, the following terms have the stated meanings. The term “subject” refers to any human or other mammalian species that could potentially benefit from treatment with a FPR2 and/or FPR1 agonist as understood by practioners in this field. Some subjects include human beings of any age with risk factors for cardiovascular disease. Common risk factors include age, sex, weight, family history, sleep apnea, alcohol or tobacco use, physical inactivity arrthymia or signs of insulin resistance such as acanthosis nigricans, hypertension, dyslipidemia, or polycystic ovary syndrome (PCOS). The term “patient” means a person suitable for therapy as determined by practitioners in the field. “Treating” or “treatment” cover the treatment of a patient or subject as understood by practitioners in this field. “Preventing” or “prevention” cover the preventive treatment (i.e., prophylaxis and/or risk reduction) of a subclinical disease-state in a patient or subject aimed at reducing the probability of the occurrence of a clinical disease-state as understood by practitioners in this field. Patients are selected for preventative therapy based on factors that are known to increase risk of suffering a clinical disease state compared to the general population. “Therapeutically effective amount” means an amount of a compound that is effective as understood by practitioners in this field.
Another aspect of the invention are pharmaceutical compositions comprising a therapeutically effective amount of a compound of Formula (I) in combination with a pharmaceutical carrier.
Another aspect of the invention are pharmaceutical compositions comprising a therapeutically effective amount of a compound of Formula (I) in combination with at least one other therapeutic agent and a pharmaceutical carrier.
“Pharmaceutical composition” means a composition comprising a compound of the invention in combination with at least one additional pharmaceutically acceptable carrier. A “pharmaceutically acceptable carrier” refers to media generally accepted in the art for the delivery of biologically active agents to animals, in particular, mammals, including, i.e., adjuvant, excipient or vehicle, such as diluents, preserving agents, fillers, flow regulating agents, disintegrating agents, wetting agents, emulsifying agents, suspending agents, sweetening agents, flavoring agents, perfuming agents, anti-bacterial agents, anti-fungal agents, lubricating agents and dispensing agents, depending on the nature of the mode of administration and dosage forms.
Pharmaceutically acceptable carriers are formulated according to a number of factors well within the purview of those of ordinary skill in the art. These include, without limitation: the type and nature of the active agent being formulated; the subject to which the agent-containing composition is to be administered; the intended route of administration of the composition; and the therapeutic indication being targeted. Pharmaceutically acceptable carriers include both aqueous and non-aqueous liquid media, as well as a variety of solid and semi-solid dosage forms. Such carriers can include a number of different ingredients and additives in addition to the active agent, such additional ingredients being included in the formulation for a variety of reasons, e.g., stabilization of the active agent, binders, etc., well known to those of ordinary skill in the art. Descriptions of suitable pharmaceutically acceptable carriers, and factors involved in their selection, are found in a variety of readily available sources such as, for example, Allen, L. V., Jr. et al., Remington: The Science and Practice of Pharmacy (2 Volumes), 22nd Edition, Pharmaceutical Press (2012).
Particularly when provided as a single dosage unit, the potential exists for a chemical interaction between the combined active ingredients. For this reason, when the compound of the present invention and a second therapeutic agent are combined in a single dosage unit they are formulated such that although the active ingredients are combined in a single dosage unit, the physical contact between the active ingredients is minimized (that is, reduced). For example, one active ingredient may be enteric coated. By enteric coating one of the active ingredients, it is possible not only to minimize the contact between the combined active ingredients, but also, it is possible to control the release of one of these components in the gastrointestinal tract such that one of these components is not released in the stomach but rather is released in the intestines. One of the active ingredients may also be coated with a material that affects a sustained-release throughout the gastrointestinal tract and also serves to minimize physical contact between the combined active ingredients. Furthermore, the sustained-released component can be additionally enteric coated such that the release of this component occurs only in the intestine. Still another approach would involve the formulation of a combination product in which the one component is coated with a sustained and/or enteric release polymer, and the other component is also coated with a polymer such as a low viscosity grade of hydroxypropyl methylcellulose (HPMC) or other appropriate materials as known in the art, in order to further separate the active components. The polymer coating serves to form an additional barrier to interaction with the other component.
Another aspect of the invention is a method for treating heart disease comprising administering a therapeutically effective amount of a compound of Formula (I) to a patient.
Another aspect of the invention is a method for treating heart disease wherein the heart disease is selected from the group consisting of angina pectoris, unstable angina, myocardial infarction, heart failure, acute coronary disease, acute heart failure, chronic heart failure, and cardiac iatrogenic damage.
It will be understood that treatment or prophylaxis of heart failure may involve treatment or prophylaxis of a cardiovascular event as well. Treatment or prophylaxis as referred to herein may refer to treatment or prophylaxis of certain negative symptoms or conditions associated with or arising as a result of a cardiovascular event. By way of example, treatment or prophylaxis may involve reducing or preventing negative changes in fractional shortening, heart weight, lung weight, myocyte cross sectional area, pressure overload induced cardiac fibrosis, stress induced cellular senescence, and/or cardiac hypertrophy properties, or any combination thereof, associated with or arising as a result of a cardiovascular event. Treatment may be administered in preparation for or in response to a cardiovascular event to alleviate negative effects. Prevention may involve a pro-active or prophylactic type of treatment to prevent the cardiovascular event or to reduce the onset of negative effects of a cardiovascular event.

A consideration in the planning of any synthetic route in this field is the choice of the protecting group used for protection of the reactive functional groups present in the compounds described in this invention. An authoritative account describing the many alternatives to the trained practitioner is Greene, T. W. et al., Protecting Groups in Organic Synthesis, 4th Edition, Wiley (2007)).
Compounds having the general Formula (I′), (II′) or (III′) wherein A, B and C correspond to Ar2, Ar3, and Ar1, respectively, can be prepared by the following one or more of the synthetic Schemes.
1-Arylpyrrolidinone compounds of this invention wherein rings A and B are substituted phenyl rings or heteroaryl rings can be prepared by the general route shown in Scheme 1. Compound 1a was synthesized as per the procedure reported in the patent literature (WO2015079692). Compound 1b where PG is a protecting group such as Boc or Cbz Compound was synthesized by Curtius rearrangement for example 1a was treated with diphenylphosphoryl azide (DPPA) and a tertiary amine such as triethylamine (TEA). Subsequent addition of benzyl alcohol yielded Cbz protected compound 1b. Copper or Pd-catalyzed coupling of 1b to a substituted heteroaryl compounds in a suitable solvent such as butanol or dioxane or toluene, in the presence of a base such as potassium carbonate or cesium carbonate and a suitable ligand such as N,N′-dimethylethylenediamine, or Xanthphos can afford desired compounds 1c. Suitable heteroaryl halides are either commercially available or can be readily obtained from the corresponding readily available starting materials by methods known to one skilled in the art. Additional methods for this transformation include other variations of Ullmann, Goldberg, and Buchwald copper-catalyzed amidation or Buchwald Pd-catalyzed C—N coupling depending on the nature of ring B, using methods known to one skilled in the art for these types of couplings (see for example Yin & Buchwald, Organic Lett. 2000, 2, 1101; Klapers et al., JACS, 2001, 123, 7727; Klapars et al., JACS, 2002, 124, 7421; Yin & Buchwald, JACS. 2002, 124, 6043; Kiyomor, Madoux & Buchwald, Tet. Lett., 1999, 40, 2657). Removal of the protecting group from 1c, followed by condensation of the resulting free amine with a suitably substituted aryl isocyanate or cycloalkyl isocyanate, or cycloakyl acids can provide ureas 1d. Suitable isocyanates or cycloakyl acids are either commercially available or can be readily obtained by methods known to one skilled in the art.
Similarly, 1-arylpyrrolidinone compounds of this invention (Formula (I′), (II′), or (III′)) wherein rings A and B are substituted phenyl rings or heteroaryl rings can be prepared by the general route shown in Scheme 2.
