Description

NEW MACROCYCLIC LRRK2 KINASE INHIBITORS
Field of the invention
The present invention relates to novel macrocyclic compounds and compositions containing said compounds acting as kinase inhibitors, în particular as inhibitors of LRRK2 (Leucine-Rich Repeat Kinase 2). Moreover, the present invention provides processes for the préparation of the disclosed compounds, pharmaceutical compositions containing them, as well as methods of using them, for instance as a medicine or diagnostic agent, în particular for the treatment and/or diagnosis of diseases impacted or moduiated by LRRK2 kinase activity such as neurological disorders including Parkinson’s disease and Alzheimer’s disease, but also cardîac diseases or inilammatory disorders such as Crohn’s disease.
Background of the invention
Parkinson’s disease is the most common movement disorder and the second most common neurodegenerative disease after Alzheimer’s disease. Parkinson’s disease affects approximately 1% of the population above 65 years and is characterized by the four classical core motor complications: resting tremor, bradykinesia, postural instability and muscular rigidity. Patients with Parkinson’s disease are also impacted by a host of non-motor symptoms such as constipation, hyposmia, orthostatic hypotension, sleep disturbances including REM sleep behavior disorder, dementia, vîsual disturbances, dépréssion, anxiety, hallucinations and mood swings.
Standard of care in Parkinson’s disease is symptomatîc relief of motor complications using dopamine replacement therapy such as the dopamine precursor L-dopa, dopamine agonists or compounds that impact the half-life of dopamine such as MAO-B inhibitors. As of today, there is no approved therapy to prevent, cure or delay the progression of Parkinson’s disease.
The pathological hallinarks of Parkinson’s disease are the loss of dopaminergic neurons in the substantia nigra pars compacta as well as postmortem evidence of protein inclusions, also known as Lewy bodies and Lewy neurites. In postmortem tissue from Parkinson’s disease patients Lewy bodies and neurites are seen throughout the central nervous System and in peripheral tissues as well. A major component of the inclusions is the aggregated and misfolded α-synuclein protein phosphorylated at a serine at amino acid position 129 (Nature 388, 839840, 1997; Nat Cell Biol 4, 160—64, 2002). Lewy bodies and neurites also contain proteins implicated in other neurodegenerative diseases such as the hyperphosphorylated tau protein which is a pathological hallmark of tauopathies such as Alzheimer’s disease (AD), frontotemporal dementia (FTD), progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD) (Biochem Soc Trans 26(3), 463-71, 1998; Am J Hum Genet 64(2), 414-21, 1999; J Neuropathol Exp Neurol 62(4), 389-97, 2003). The pathological process in Parkinson’s dîsease is not restrîcted tothe loss of dopaminergic neurons in the basal ganglîa system. Distinct neuronal populations in other brain régions such as the neocortex, sleep nuclei or the raphe nucléus as well as peripheral organs and tissues such as the heart and the gastro-intestinal system are also impacted by degenerative processes in Parkinson’s disease patients.
Leucine-rich repeat kinase 2 (LRRK2) is a 2527 amino acid protein with a molecular weight of 286 kDa that is encoded by the LRRK2 gene. It consists of the following functional and structural proteins domains: armadillo (ARM), ankyrin (ANK), leucine rich repeat (LRR), Ras of complex domain (Roc), c-terminal of Roc (COR), map kinase (MAPK) and tryptophanaspartate repeat domain (WD40). LRRK2 exists primarily as a dimeric protein either associated with membrane structures or cytoplasmîc localized. The armadillo, ankyrin, LRR and WD40 protein-protein interaction domains enabies LRRK2 to interact with a host of different protein partners to impact its own as well as its partner proteins subcellular localization. The central enzymatic core of the LRRK2 protein containing the Roc-COR and the MAPK domain hâve distinct GTPase and ATPase enzymatic activities enabling LRRK2 to phosphorylate and control the function of intracellular substrates. LRRK2 impacts, via its enzymatic activity and substrate interactions, various subcellular processes and biological mechanisms important for trafficking of intracellular vesicular structures and organelles such as lysosomes, endosomes, autophagosomes, the Golgi and mitochondria. Structural work as well as modelling highlights how naturally occurrîng missense variation in functional and structural domains of LRRK2 impacts enzymatic activity (bioRxiv 2020.01.06.895367). In the inactive (open) LRRK2 conformation there are major interactions between the enzymatic GTPase (Roc-COR) and ATPase (MAPK) domains. In addition, the ultimate C-terminaî proceeding the WD40 domain binds along the entire kinase (MAPK) domain. In the active (closed) LRRK2 conformation the LRR domain positions the autophosphorylation site Serl292 in proximity to the kinase active site. Phosphorylation of LRRK2 at a cluster of serines immediately preceding the LRR domain enabies the LRR domain of LRRK2 to bind to 14-3-3 proteins. Among those phosphorylation sites are serines (Ser) at the following amino acid positions: Ser910, Ser935, Ser955 and Ser973. Pathogenic LRRK2 mutations originating in the GTPase domain has diminished phosphorylation at these sites and therefore reduced 14-3-3 bindîng leading to încreased microtubule network recruitment. Ail ATP-compétitive LRRK2 inhibitors induce déphosphorylation at the Ser9i0, Ser935, Ser955 and Ser973 sites making these sites useful as surrogate target engagement markers (Biochem J 430(3), 405-13, 2010; J Neurochem 120(1),
37-45, 2012). The bona fide LRRK2 substrates consists of a subset of small Rab GTPases including RablO and Rab29. The Golgi-resident protein Rab29 also known as Rab7Ll is a Parkinson’s disease susceptibility gene located at the PARKI6 locus (Nat Genet 41(12), 130812, 2009).
Rare protein-encoding variants in the LRRK2 gene cause Parkinson’s disease. The most common pathogenic variant causing autosomal dominant familial Parkinson’s disease is the p.G2019S substitution which changes a glycine to a serine in the activation loop of the LRRK2 kinase domain rendering the p.G2019S variant more active than the wild type LRRK2 protein (Lancet 365(9457), 412-5, 2005). This results in ïncreased autophosphorylation at the serine at amino acid position 1292 (Sci Transi Med, 4(164), 164ral61, 2012). The estïmated worldwide prevalence of the p.G2019S mutation in patients with PD is 1-2%; whereas , in Ashkenazi Jewish and North African Arab-Berber populations the p.G2019S prevalence in PD patients is up to 30% and 40%, respectively (Lancet Neurol 7, 583-90, 2008; N Engl J Med 354(4), 4245, 2006; Lancet Neurol 7, 591-4, 2008). The clinical manifestation of Parkinson’s disease in patients carrying the p.G2019S mutation is indistinguishable from patients with the sporadic form of Parkinson’s disease (Ann Neurol 57(5), 762-5, 2005). Besides p.G2019S seven additional rare LRRK2 exonic variants having non-synonymous amino acid substitutions in the central enzymatic core (p.N1437H; p.R1441C/G/H; p.YI699C; p.S1761R; p.I2020T) also cause autosomal dominant Parkinson’s disease (Parkinsonism Relat Disord 15(6), 466-7, 2009; Mov Disord 25(14), 2340-5, 2010; Neuron 44(4), 601-7, 2004; Parkinsonism Relat Disord 18(4), 332-8, 2012; Ann Neurol 57(6), 918-21, 2005; Mov Disord 27(1), 146-51, 2012). As with p.G2019S the clinical représentations are indistinguishable from idiopathic PD (Neurology 70, 1456-60, 2008). LRRK2 missense variants exhibit ïncreased Ser 1292 phosphorylation, ïncreased trans-Golgi recruitment by Rab29 and ïncreased phosphorylation of RablO at amino acïd position 73 (Rabl0-Thr73) that can be reversed by LRRK2 inhibition (Sci Transi Med 4(164), 164raI61, 2012; EMBO J 37(1), 1-18, 2018; Proc Natl Acad Sci USA 111, 2626-31, 2014). Common protein-coding variants in the LRRK2 gene are also associated with risk of Parkinson’s disease. Variants such as p.A419V, p.M1646T, p.R1628P and p.G2385R increase the risk of Parkinson’s disease and hâve ïncreased kinase activity (bioRxiv 447946, 2018) (Proc Natl Acad Sci USA 116(5), 1579-1584, 2019) whereas the p.N551K variant is associated with reduced risk of Parkinson’s disease (Lancet Neurol 10(10), 898-908, 2011) and hâve reduced kinase activity (bioRxiv 447946, 2018). Evidence that LRRK2 also plays a rôle in sporadic Parkinson’s disease cornes from both genetic studies as well as postmortem analyses of PD brains. A single nucléotide polymorphism (SNP) at the LRRK2 genetic locus is genome-wide associated with risk of Parkinson’s disease (Nat Genet 46(9), 989-93, 2014). This particular SNP variant is associated with increased LRRK2 expression (Sci Transi Med 9 (421), 2017) which is in agreement with the increased LRRK2 kinase activity observed in surviving dopamine neurons from postmortem brains of sporadic PD patients (Sci Transi Med 10 (451), 2018).
Thus, inhîbîtors of LRR.K2 kinase activity can be used as thérapies for both sporadic PD patients as well as for PD patients with LRRK2 mutations or Rab29/Rab7Ll polymorphisms.
Parkinson’s disease risk loci containing several genes encoding proteins involved in endosomal-lysosomal processes such as GBA, SCARB2, GALC, VPS35, LAMP1, VPS13C, VPS35, TMEM175, ATP6V0A1 and CTSB hâve been identified by Genome Wide Association Study (GWAS) and linkage studies. LRRK2 also plays a key rôle in the endosomal-lysosomal System and in the processes linked to endosomal function such as autophagy and mitophagy. LRRK2 interacts with the vacuolar H+-ATPase a subunit to regulate lysosomal pH and endosomal-lysosomal dysfunction induced by rotenone, a toxin known to be associated with increased risk of Parkinson’s disease, can be alleviated by LRRK2 inhibition (Newobiol Dis 134, 104626, 2020). Dîsease-causing LRRK2 mutations induce lysosomal stress by enlarging lysosomes (Hum Mol Genet 24(21), 6013-28, 2015). Lîkewise, an aspartate to asparagine missense mutation in the retromer complex protein VPS35 at amino acid position 620 (VPS35D620N) causes late onset autosomal dominant familial Parkinson’s disease. In the disease State the VPS35-D620N missense mutation disrupts trafficking of cathepsin D, the protease responsible for dégradation of α-synuclein (Traffic 15(2), 230-44, 2014) and activâtes LRRK2 which leads to increased autophosphorylation atthe LRRK2-Serl292 site and increased RablOThr73 phosphorylation (Biochem J 475(11), 1861-1883, 2018). In the lysosomes LRRK2 interacts with GBA that is causally linked with the lysosomal storage disorder Gaucher’s disease and a risk gene for Parkinson’s disease. LRRK2 missense mutations reduce GBA activity that can be counteracted by LRRK2 inhibition (Nat Commun 10(1), 5570, 2019). Reversely, GBA disease-relevant déficits in lysosomal biology processes in astrocytes can also be alleviated by LRRK2 inhibition (Mov Disord Feb 8, 2020, doi: 10.1002/mds.27994). Missense mutations în the mitochondrial kinase PINK1 and the E3 ligase PARKIN both cause autosomal récessive early onset Parkinson’s disease that is associated with mitochondrial dysfunction (Science 304(5674), 1158-60, 2004; Nature 392(6676), 605-8, 1998). LRRK2dependent phoshorylation ofRab8a on threonine at amino acid position 72 is modulated by PIN Kl phosphorylation of serine on amino acid position 111 on Rab8a (Biochem J. Mar 30,
2020, doi: 10.1042/BCJ20190664). Besides this LRRK2 activity impairs mitophagy that under normal conditions is regulated by the PINK1/PARKIN pathway. This can be reversed by LRRK2 inhibition (Hum Mol Genet 28(10), 1645-1660, 2019). LRRK2 missense mutations cause mitochondrial DNA damage that can be reversed by gene corrections (Neurobiol Dis 62, 381-6, 2014) as well as with inhibitors of LRRK2 (Hum Mol Genet. 26(22), 4340-4351, 2017). This suggests that LRRK2 inhibitors are useful for treating lysosomal storage disorders such as Gaucher’s disease, Krabbe’s disease, Niemann-Pick’s disease and Fabry’s disease, disorders with mitochondrial déficits including early onset Parkinson’s disease associated with PINK1 and PARKIN missense mutations as well as Parkinson’s disease in patients with poiymorphisms in genes encoding proteins involved in the endosomal-lysosomal system such as GBA, GALC, VPS35, VPSI3C, ATP6V0A1, LAMP1, SCARB2, TMEM175 and CTSB.
Postmortem analysis of brains from Parkinson’s disease patient carrying LRRK2 mutations show presence of α-synuclein pathology (JAMA Neurol. 72(1), 100-5, 2015). In preclinical Parkinson’s disease (PD) models, p.G2019S aggravâtes PD-related pathology that can be reversed by LRRK2 inhibition. LRRK2 has been identified in Lewy bodies in nigral and brain stem régions (Neuropathol Appl Neurobiol 34(3), 272-83, 2008) and has also been shown to phosphorylate α-synuclein on Serl29 (Biochem Biophys Res Commun 387(1), 149-52, 2009). LRRK2 exonic variation is associated with risk of multiple system atrophy (Neurology 83(24), 2256-61, 2014) and LRRK2 missense mutations hâve also been reported in patients with multiple system atrophy (J Parkinsons Dis;8(l), 93-100, 2018). Single nucléotide poiymorphisms in the MAPT (tau) locus is associated with increased risk of Parkinson’s disease and multiple system atrophy (Hum Genet 124(6), 593-605, 2009; Parkinsonism Relat Disord 30, 40-5, 2016). Tau pathology is also a prominent feature seen in Parkinson’s disease patients with LRRK.2 missense mutations (ActaNeuropathol Commun 7(1), 183, 2019). Overexpression of pathogenic LRRK2 in animal models increase tau pathology (Neurobiol Dis 40(3), 503-17, 2010). LRRK2 missense mutations hâve been reported in patients suffering from tauopathies such as progressive supranuclear palsy and corticobasal degeneration (Mov Disord. 32(1), 115123, 2017). Common variation at the LRRK2 locus îs associated with survival in the primary tauopathy progressive supranuclear palsy (bioRxiv 2020.02.04.932335) and GWAS studies hâve identified risk for frontotemporal dementia at the LRRK2 locus (PLoS Med 15(1), e!002487, 2018).
This suggests that LRRK2 inhibitors are useful for treating synucleinopathies and tauopathies including frontotemporal dementia, progressive supranuclear palsy, corticobasal degeneration and Alzheimer’s disease.
LRRK2 mRNA and protein are broadly expressed but particular enriched in brain tissue as well as m peripheral organs more specifically kidney, lung, intestine and spleen. Besidesthîs LRRK2 expression is highly enriched in immune cells in the brain and in neutrophils, B-cells, macrophages and monocytes in the periphery. LRRK2 mRNA and protein expression is induced after pro-inflammatory stïmuli or pathogens thereby increasing LRRK2 kinase activity. In human peripheral blood mononuclear cells, the LRRK2 substrates RablO and Rabl2 are phosphorylated after stimulation with reagents mimicking viral infections (Sci Rep 7(1), 10300, 2017). Consistent with LRRK2 biology playing a rôle in response to înflammatory stimuli LRRK2 missense mutations are associated with risk of the Înflammatory bowel disorder Crohn’s disease and GWAS studies has identified single nucléotide polymorphisme in the LRRK2 locus associated with genome wide significant risk of Crohn’s disease (Inflamm Bowel Dis 17(12), 2407-15, 2011). In Ashkenazi Jewish populations there is a two- to four-fold increased prevalence of Crohn’s disease and in the same population LRRK2 variants are associated with increased risk of Crohn’s disease (PLoS Genet 14(5), e!007329, 2018). LRRK2 exonic variants such as p.N208lD and p.M2397T increase the risk of Crohn’s disease and as observed for Parkinson’s disease the protective haplotype variant p.N551 K/p.R1348H lowers the risk of Crohn’s disease. In cell-based studies the p.N2081D variant has increased kinase activity which leads to augmented RablO phosphorylation (bioRxiv 447946, 2018; Sci Transi Med 10(423), 2018). The biological link between Parkinson’s disease and autoimmune disorders are further supported by studies finding that commun genetic pathways which also includes LRRK2 are shared between Parkinson’s disease and autoimmune disorders such as rheumatoid arthritîs, ulcerative colitis and Crohn’s disease (JAMA Neurol 74(7), 780-92, 2017). Consistent with this LRRK2 is also associated with risk of lupus (Oncotarget8, 13754-61, 2017; J Transi Med 17(1), 37, 2019) and leprosy (N Engl J Med 361(27), 2609-18, 2009; PLoS One 8(8), e73I03, 2013; PLoSNegl Trop Dis 10(2), e0004412, 2016).
Thus, LRRK2 inhibitors can be used for treatment of Crohn’s disease and other autoimmune disorder such as but not restricted to rheumatoid arthritîs, ulcerative colitis, lupus and leprosy. LRRK2 play s a rôle in tumor growth in rénal and thyroid cancers by impacting MET signaling, and lowering of LRRK2 expression induces growth arrest (Proc Natl Acad Sci USA 108(4), 1439-44, 2011). LRRK2-PD patients hâve increased risks of leukemia as well as skin and colon cancers (Mov Disord34(9), 1392-8, 2019). Carriers of p.G2019S also hâve an overall increased risk of non-skin cancer;in particular breast cancer and hormone-related cancers in females (JAMA Neurol 72(1), 58-65, 2015). Studies hâve shown that LRRK2 silencing promûtes T-cell growth inhibition and facilitâtes apoptosis and cell cycle arrest (Int J Oncol 55(1), 21-34, 2019).
LRRK2 is also differentially expressed in lung adeno- and lung squamous cell carcinomas as well as ποη-small-cell lung cancer (J Cell Physiol 234(7), 10918-25, 2019; J Cell Physiol 234(12). 22742-52. 2019).
Thus, LRRK2 inhibitors hâve anti-carcinogenîc effects and can be used for treatment of skin cancer and non-skin cancers such as rénal cancer, colon cancer, adeno- and squamous lung cancers, non-small-cell lung cancer, hormone-related cancer, thyroid cancer, leukemia and breast cancer.

PHARMACOLOGICAL STUDY
EXAMPLE A: LRRK2 Kinase Activity Assay
Protocol
LRRK2 Kinase reactions were carried out in 384-well white polystyrène plates in a final volume of 6 μΙ using ADP-Glo™ Kinase Assay kit (Promega Corp.). Compound and substrates (LRRKtide peptide and ATP) in assay buffer were first dispensed in wells. Kinase reaction was then started by the addition of human recombinant LRRK2 protein. After l h-incubation at 37°C, the enzymatic reaction was stopped by the addition of 6 μΐ of ADP-Glo Reagent-1 and an additional 40-minutes incubation at 23°C (residual ATP déplétion). A final 30-minutes incubation after !2gL reagent-2 addition (ADP to ATP conversion and luciferin/luciferase reaction) was performed before luminescent signal acquisition (EnVision™ multimode plate reader - PerkînElmer, Inc.). Data from 10 individual concentrations of tested compounds (N=2) were fitted (XLfit™ - ID Business Solutions Ltd) to deliver IC50S (compound concentration leading to 50% inhibition of reference enzymatic activity).
Compounds
The compounds are dissolved to 5 mM in DMSO. When needed, solutions are sonicated in a bath sonicator.
Table 2 provides the IC50 values of the compounds according to the invention, obtained using the above-mentioned kinase assay. Activities are represented as +++, ++ and +, having the following meanings:
+++ means IC50 < 10 nM ++ means 10 nM < IC50 < 100 nM + means 100 nM < IC50 < l μΜ.
