Title: Tetrahydroisoquinoline compounds as nrf2 activators

Description:
INTRODUCTION 
     The present invention relates to tetrahydroisoquinoline compounds. More specifically, the present invention relates to tetrahydroisoquinoline compounds that are Nrf2 activators. The present invention also relates to processes for the preparation of these compounds, to pharmaceutical compositions comprising them, and to their use in the treatment of diseases or disorders associated with Nrf2 activation and/or inhibition of Keap1-Nrf2 protein-protein interactions. 
     BACKGROUND OF THE INVENTION 
     Nuclear factor erythroid 2-related factor 2 (Nrf2) is a basic leucine zipper (bZIP) transcription factor and a member of the Cap ‘n’ Collar (CNC) family of transcription factors. It is a key master of the inducible cell defence system, mediating the expression of more than 100 oxidative stress-related genes that include phase I and II detoxification enzymes and antioxidant proteins. These genes all contain the antioxidant response element (ARE) in their promoter regulatory regions, which is the binding target of Nrf2. Under basal conditions the levels of N112 are tightly regulated by the adaptor protein Keap1, a cytosolic actin-bound repressor protein, which binds to Nrf2 and leads to proteasomal degradation via the Cul3-based E3 ubiquitin ligase complex. Under conditions of oxidative stress, Keap1 is inactivated leading to an increase in the level of de novo synthesised Nrf2 which translocates to the nucleus, binds to AREs with a resulting up-regulation in cytoprotective gene expression. 
     It has been shown that Nrf2 mRNA expression in COPD subjects was significantly lower than that in control subjects and Nrf2 mRNA were negatively correlated with pack year. Nrf2 protein in COPD subjects was significantly lower than that in control subjects. CSE-induced A549 cell apoptosis was increased in a time-dependent and concentration-dependent manner, and was significantly increased by Nrf2 knockdown (Yamada,  BMC Pulmonary Medicine , doi:10.1186/s12890-016-0189-1). Therefore, elevation of Nrf2 levels in the lungs of COPD patients should lead to a reduction in the inflammatory processes that lead to deleterious structural modifications of the lung and slow disease progression. 
     Nrf2 may also be expected to show positive benefits in other respiratory diseases that exhibit oxidative stress components (Cho,  Toxicol Appl Pharmacol , doi: 10.1016/j.taap.2009.07.024) such as acute, chronic and severe asthma (Sussan,  Am J Physiol Lung Cell Mol Physiol , doi:10.1152/ajplung.00398.2014), acute lung injury/acute respiratory distress syndrome, with or without accompanying multi organ dysfunction syndrome (Yan,  Free Radical Biol Med, doi: 10.1016/j.freeradbiomed.2018.04.557; de la Vega  Curr Pharmacol Rep , doi:10.1007/s40495-016-0053-2), pulmonary fibrosis, including idiopathic pulmonary fibrosis (Kikuchi,  Respir Res, doi: 10.1186/1465-9921-11-31) and cystic fibrosis (Chen,  PLoS One , doi:10.1371/journal.pone.0003367). Indeed, the combination of cytoprotection by restoring redox and protein homeostasis, promoting resolution of inflammation, and facilitating repair in the lungs by Nrf2 activators has highlighted their potential for the treatment of COVID-19 (Cuadrado et al, Trends Pharmacol Sci, doi:10.1016/j.tips.2020.07.003). 
     The cardiac protective nature of Nrf2 in models of atherosclerosis, ischaemia, reperfusion, cardiac hypertrophy and heart failure has been demonstrated (Chen,  Physiol Genomics , doi:10.1152/physiolgenomics.00041.2017). The Nrf2 activator Bardoxolone methyl has recently completed a Phase II study in patients with pulmonary arterial hypertension (PAH), with a Phase III study underway based on a significant improvement in 6 minute walking distance. Bardoxolone reacts covalently with Keap1 but compounds activating Nrf2 via alternative mechanisms of Keap1 binding should also be expected to be therapeutically useful in PAH, particularly in patients that also have an underlying connective tissue disorder (CTD), such as scleroderma or lupus erythematosus. Oxidative stress is elevated in the diseased myocardium, leading to raised levels of reactive oxygen species which impact negatively on cardiac function (Bolli,  Circ , doi: 10.1161/circ.76.2.3111744). Nrf2 activation has been shown to suppress myocardial oxidative stress, cardiac apoptosis, hypertrophy, fibrosis and dysfunction in mouse models of pressure overload (Wang,  J Card Failure , doi:10.1016/j.cardfail.2012.06.003) and to protect against cardiac ischemic/reperfusion injury in rodent models (Zhang,  J Mol Cell Cardiol , doi:10.1016/j.yjmcc.2010.05.01). Furthermore, excessive production of oxidizing agents in detriment of antioxidant defences in the cardiovascular system has also been described in metabolic diseases such as obesity, metabolic syndrome and diabetes mellitus where activation of Nrf2 has also been suggested as a promising therapeutic strategy (da Costa,  Front Pharmacol. , doi:10.3389/fphar.2019.00382). In addition, the Nrf2 activator sulforaphane reduces hepatic glucose production and improves glucose control in patients with type 2 diabetes (Axelsson,  Sci Transl Med. , doi: 10.1126/scitranslmed.aah4477) and bardoxolone methyl has been shown to induce weight loss in generally obese patients in proportion to baseline BMI alongside improving glycaemic control (Chertow et al, J Diabetes Complications, doi: 10.1016/j.jdiacomp.2018.09.005). Age-associated mitochondrial dysfunction and oxidative damage are primary causes for multiple health problems including sarcopenia and cardiovascular disease and treatment of aging mice with the Nrf2 activator Sulforaphane restored Nrf2 activity, mitochondrial function, cardiac function, exercise capacity, glucose tolerance, and activation/differentiation of skeletal muscle satellite cells (Bose et al, Aging cell, doi:10.111 1 / a ce1.13261). Thus, it is expected that drugs leading to activation of Nrf2 should be useful in a number of cardiovascular and metabolic diseases including, but not limited to, atherosclerosis, hypertension, heart failure, myocardial infarction and repair, cardiac remodelling, cardiac arrhythmias, heart failure with reduced ejection fraction, diabetic cardiomyopathy, diabetic nephropathy, metabolic syndrome, obesity, diabetes mellitus (type 1 or type 2) and insulin resistance. 
     Subarachnoid haemorrhage (SAH) is a devastating condition with high morbidity and mortality rates due to the lack of effective therapy. Early brain injury (EBI) and cerebral vasospasm (CVS) are the two most important pathophysiological mechanisms for brain injury and poor outcomes for patients with SAH (clinicaltrials.gov/ct2/show/NCT0261474, SFX01 After Subarachnoid Haemorrhage (SAS)). Evidence from experimental SAH research indicates a protective role of the Nrf2/ARE pathway in EBI and CVS after SAH. Administration of sulforaphane (SFN) to rats following SAH enhances the activity of the Nrf2-ARE pathway, attenuates vasospasm in basilar arteries and suppresses the release of proinflammatory cytokines (Zhao,  Brain Res. , doi: 10.1016/j.brainres.2016.09.035). Intracerebral haemorrhage (ICH) is the primary event in 10-15% of the 15 million strokes occurring annually worldwide. In vitro studies demonstrated that Nrf2 activators rapidly increased HO-1 expression in astrocytes and reduced their vulnerability to haemoglobin or hemin. Systemic treatment with small molecule Nrf2 activators increased HO-1 expression in perivascular cells, particularly astrocytes. When tested in mouse or rat ICH models, Nrf2 activators were consistently protective, improving barrier function and attenuating edema, inflammation, neuronal loss and neurological deficits (Chen-Roetling,  Curr Pharm Des , doi:10.2174/1381612822666161027150616). Ischemic stroke induces reactive oxygen species, causing oxidative and inflammatory responses in ischemic brain. To date, recombinant tissue plasminogen activator is the only available therapy for the treatment of ischemic stroke. However, the treatment does not prevent oxidative stress and inflammation in the ischemic brain. D3T, a sulfur-containing dithiolethione compound, is found in cruciferous vegetables and has been reported to induce anti-oxidant genes through activation of Nrf2. D3T has been shown (Yen,  J Immunol  2017, 198 (1 supplement) 206.20) to attenuate brain infarct and ameliorate neurological deficits in stroke animals. In addition, D3T reduced CNS infiltrating inflammatory immune cells including neutrophils and monocytes in the ischemic brain. Moreover, D3T-induced suppression of inflammatory cytokine production was observed in wild-type but not in Nrf2-deficient microglia. Furthermore, the protective effect of D3T on the attenuation of ischemic brain infarct was abolished in Nrf2-deficient stroke animals and in the stroke animals administered with HO-1 inhibitor. These results suggest that D3T-mediated suppression of inflammation in the ischemic brain is mediated through Nrf2/H 0 -1 pathway, and thus that targeting the Nrf2/H 0 -1 pathway may be a promising therapeutic strategy for the amelioration of neuroinflammation in ischemic stroke. 
     Nrf2 is believed to play a key role in some hemoglobinopathies, such as beta-thalassemia and sickle cell disease (SCD). SCD is a recessive inherited disorder caused by a single missense mutation which leads to the mutated beta-globin protein haemoglobin S (HbS). At low oxygen concentrations HbS polymerises, leading to misshapen red blood cells which are prone to rupture, releasing free heme into plasma. The resulting oxidative stress and inflammation leads to damage in multiple organs of the body. Ablation of Keap1 and the resulting constitutive activation of Nrf2 has been shown to lead to improved outcomes in SCD model mice (Zhu,  Blood , doi:10.1182/blood-2017-10-810531; Keleku-Lukwete PNAS, doi:10.1073/pnas.1509158112). Nrf2 activation has been shown to slow down the progression of haemolytic anemia and organ disfunction (Ghosh,  JCI Insight , doi: 10.1172/jci.insight.81090) and loss of Nrf2 function worsens the pathophysiology of SCD in transgenic SCD mice (Zhu,  Blood , doi.org/10.1182/blood-2017-10-810531). Global activation of Nrf2 with the known compound D3T reduces lethality in a haem-induced acute chest syndrome model in transgenic SCD mice (Ghosh, Brit.  J. Haematology  doi: 10.1111/bjh.15401). In addition, Nrf2 activators have also been shown to modulate foetal haemoglobin (HbF) expression through direct binding in the gamma-globin promoter and modification of chromatin structure in the beta-globin locus. In sickle erythroid cells, Nrf2 provides unique benefits through HbF induction to inhibit haemoglobin S polymerization and protection against oxidative stress due to chronic haemolysis (Zhu,  Exp Biol Med  doi: 
     10.1177/1535370219825859). Thus, the development of small molecule activators of Nrf2 has the potential to ameliorate the clinical severity of sickle cell disease and other diseases where increasing HbF is beneficial such as beta-thalassemia. 
     The function of Nrf2 is altered in many neurodegenerative disorders, such as Huntington&#39;s disease, Parkinson&#39;s Disease, Alzheimer&#39;s disease, amyotrophic lateral sclerosis, frontotemporal dementia, multiple sclerosis and Friedreich&#39;s ataxia (Dinkova-Kostova,  FEBS , doi:10.1111/febs.14379). Nrf2 activation mitigates multiple pathogenic processes involved in these neurodegenerative disorders through upregulation of antioxidant defences, inhibition of inflammation, improvement of mitochondrial function, and maintenance of protein homeostasis. Small molecule pharmacological activators of Nrf2 have shown protective effects in numerous animal models of neurodegenerative diseases (Joshi, Neurobiol Aging, doi:10.1016/j.neurobiolaging.2014.09.004; Alarcon-Aguilar,  Neurobiol Aging , doi:10.1016/j.neurobiolaging.2014.01.143 and in cultures of human cells expressing mutant proteins. Tecfidera (dimethyl fumarate) activates Nrf2 (in addition to other mechanisms) and is approved in the US to treat relapsing-remitting multiple sclerosis. The Nrf2 activator Omaveloxolone (RTA-408) currently in Phase II trials for the treatment of the inherited neurodegenerative disorder Friedrich&#39;s ataxia, has met its primary endpoint of change in the modified Friedrich&#39;s Ataxia Rating Scale (mFARS) relative to placebo after 48 weeks of treatment. Targeting Nrf2 signalling may therefore provide a therapeutic option to delay onset, slow progression, and ameliorate symptoms of neurodegenerative disorders. Due to the role of oxidative stress and mitochondrial dysfunction in disorders of the CNS, treatment of chronic pain and schizophrenia with Nrf2 activators has also been suggested. 
     Rheumatoid arthritis (RA) is an autoimmune disease that causes chronic inflammation of the joints and is characterized by periods of disease flares and remissions. Multiple joints can be affected sometimes resulting in permanent joint destruction and deformity. Nrf2 has been found to be activated in the joints of arthritic mice and of RA patients. Nrf2-knockout mice have more severe cartilage injuries and more oxidative damage, with the expression of Nrf2 target genes being enhanced in Nrf2-wild-type but not in knockout mice during antibody-induced arthritis (Wruck,  BMJ Annals of Rheumatic Diseases , doi:10.1136/ard.2010.132720). Additionally, in an animal model of rheumatoid arthritis, using the transfer of serum from K/BxN transgenic mice to Nrf2(−/−) mice, Nrf2 deficiency accelerated the incidence of arthritis, and animals showed a widespread disease affecting both front and hind paws (Maicas,  Antioxidants  &amp;  Redox Signaling , doi:10.1089/ars.2010.3835). 
     Ulcerative colitis (UC) and Crohn&#39;s disease (CD) are chronic relapsing-remitting forms of inflammatory bowel disease (IBD) that are caused by dysfunction of the intestinal epithelium. Damage to the intestinal epithelial cells can disrupt the barrier function of the intestinal epithelium, facilitating an aberrant immune response and inflammatory conditions. Thus, the intact intestinal epithelium is critical for the healthy gut, and cyto-protective agents that could target the intestinal epithelial cells would be beneficial for the treatment of UC and CD. Antioxidant levels and oxidative stress biomarkers are typically correlated with disease severity in IBD and a number of genome-wide association studies have linked IBD-associated single nucleotide polymorphismsm (SNPs) to multiple genes involved in the response to oxidative stress, with many regulated by Nrf2 (Khor et al, Nature, doi:10.1038/nature10209). CPUY192018, a small-molecule inhibitor of the Keap1-Nrf2 protein-protein interaction (and hence Nrf2 activator) has demonstrated a cytoprotective effect in an experimental model of UC induced by dextran sodium sulphate in both NCM460 cells and mouse colon (Lu,  Scientific Reports , doi:10.1038/srep26585). It has also been shown that Nrf2 knockout mice show an increased susceptibility to colitis-associated colorectal cancer (Khor,  Cancer Prey Res  (Phila), doi:10.1158/1940-6207). 
     Fumaderm, a mixture of dimethyl fumarate (DMF) and three salts of monoethyl fumarate, was licensed in Germany in 1994 for the treatment of psoriasis. The likely bioactive form of DMF, monomethyl fumarate (MMF) has been shown to increase total and nuclear Nrf2 levels in primary mouse keratinocytes and lead to enhanced mRNA expression of several Nrf2-downstream effectors such as heme oxygenase-1 and peroxiredoxin-6. (Helwa,  J PharmacoL Exp. Ther. , doi:10.1124/jpet.116.239715). Other skin disorders may benefit from treatment with Nrf2 activators such as radiation-induced dermatitis/skin damage, atopic dermatitis and wound healing (Wu et al, Mol Med Rep. 2019 Aug. 20(2):1761-1771). 
     Activation of Nrf2 has been shown to have beneficial effects in diseases of both the liver and kidney. NAFLD (Non-alcoholic fatty liver disease) is recognized as the leading cause of chronic liver disease worldwide. NAFLD represents a spectrum of diseases, some of which can progress to cirrhosis and hepatocellular carcinoma (HCC). Although all subtypes of NAFLD increase the risk for cardiovascular events and mortality, NASH (non-alcoholic steatohepatitis) is the main diagnostic subtype of NAFLD which predisposes patients to cirrhosis and liver-related complications. There are currently approved drug treatments for NAFLD and NASH. However, knockout of Nrf2 in mice profoundly predisposes to NASH stimulated by either a methionine- and choline-deficient (MCD) diet (Chowdry,  Free Radic Biol Med , doi:10.1016/j.freeradbiomed.2009.11.007) or a high fat (HF) diet (Okada,  J Gastroenterol , doi:10.1007/s00535-012-0659-z), and pharmacologic activation of Nrf2 has been shown to reverse NASH in mouse models (Sharma,  Cell Mol Gastroenterol Hepatol , doi:10.1016/j.jcmgh.2017.11.016). Other liver diseases may benefit from treatment with Nrf2 activators such as toxin-induced liver disease, viral hepatitis and cirrhosis. Oxidative-stress molecules, such as reactive oxygen species, accumulate in the kidneys of animal models for acute kidney injury (AKI), in which Nrf2 is transiently and slightly activated. Genetic or pharmacological enhancement of Nrf2 activity in the renal tubules significantly ameliorates damage related to AKI and prevents AKI progression to chronic kidney disease (CKD) by reducing oxidative stress. However, a Phase III clinical trial of a KEAP1 inhibitor, CDDO-Me or bardoxolone-methyl, for patients with stage 4 CKD and type-2 diabetes mellitus (T2DM) was terminated due to the occurrence of cardiovascular events. Because recent basic studies have accumulated positive effects of KEAP1 inhibitors in moderate stages of CKD, Phase II trials have been restarted. The data from the ongoing projects demonstrate that a Nrf2 activator/KEAP1 inhibitor improves the glomerular filtration rate in patients with stage 3 CKD and T2DM without safety concerns (Nezu,  Am J Nephroi , doi:10.1159/000475890). Inflammatory reactions and oxidative stress are implicated in the pathogenesis of focal segmental glomerulosclerosis (FSGS), a common chronic kidney disease with relatively poor prognosis and unsatisfactory treatment regimens. CXA-10 which upregulates Nrf2 pathways is currently in clinical trials for Focal Segmental Glomerulosclerosis (FIRSTx-A Study of Oral CXA-10 in Primary Focal Segmental Glomerulosclerosis (FSGS); clinicaltrials.gov/ct2/show/NCT03422510). Bardoxolone methyl has been shown in a Phil trial to lead to significant improvement in kidney function in patients with either autosomal dominant polycystic kidney disease (ADPKD), CKD associated with type 1 diabetes (T1D), IgA nephropathy (IgAN) or FSGS after 12 weeks of treatment (https://www. reatapharma.com/press-releases/reata-an nou nces-positive-phase-2-data-for-bardoxolone-methyl-in-patients-with-focal-segmental-g lomeru losclerosis-and-in-patients-from-all-four-cohorts-of-phoenix/). Alport Syndrome is the second most common inherited cause of kidney failure caused by a genetic defect in type IV collagen, a component in building the glomerular basement membrane. As bardoxolone methyl is thought to affect the underlying pathologic processes associated with mitochondrial dysfunction, inflammation and oxidative stress, it is currently being studied in these patients suggesting Nrf2 activators will be potentially useful in this disease. 
     Oxidative stress plays a critical role in the initiation and progression of cancer (Gorrini,  Nat Rev Drug Discov ., doi:10.1038/nrd4002). Due to its importance in the maintenance of redox cellular homeostasis, Nrf2 is considered a cytoprotective transcription factor and tumour suppressor. At lower homeostatic levels Nrf2 is able to eliminate ROS, carcinogens and other DNA-damaging agents, leading to the inhibition of tumour initiation and metastasis (Milkovic et al. Redox Biol. doi:10.1016/j.redox.2017.04.013). Evgen is currently evaluating SFX-01 (sulforaphane-cyclodextrin complex) in the Treatment and Evaluation of Metastatic Breast Cancer (STEM) (clinicaltrials.gov/ct2/show/NCT02970682) which includes ER+/HER− metastatic breast cancer. Bardoxolone derivatives have been shown to prevent lung cancer induced by vinyl carbamate in A/J mice (Liby,  Cancer Res . doi:10.1158/0008-5472). Thus, activators of Nrf2 may have a role in the prevention of cancer. 
     Age related macular degeneration (AMD) is the principal cause of blindness in western countries and oxidative stress plays a major role in AMD pathogenesis and progression. It has been shown that Nrf2 activators are able to protect cells cultured to mimic the external layer of the retina from oxidative stress suggesting the potential for vision preservation in early AMD patients (Bellezza, Front Pharmacol. 2018; 9: 1280). In addition, Nrf2 activators may also be useful in other eye conditions such as Fuchs Endothelial Corneal Dystrophy and uveitis. 
     Recently, Nrf-2 activators have also been suggested to have benefit for the treatment of preeclampsia via suppression of oxidative stress and endothelial cell apoptosis (Jiang et al, Oxid Med Cell Longev doi:10.1155/2021/8839394). 
     Therefore, there is an ongoing need for agents capable of Nrf2 activation, given the role of Nrf2 in multiple indications.

     DETAILED DESCRIPTION OF THE INVENTION 
     Definitions 
     Unless otherwise stated, the following terms used in the specification and claims have the following meanings set out below. 
     It is to be appreciated that references to “treating” or “treatment” include prophylaxis as well as the alleviation of established symptoms of a condition. “Treating” or “treatment” of a state, disorder or condition therefore includes: (1) preventing or delaying the appearance of clinical symptoms of the state, disorder or condition developing in a human that may be afflicted with or predisposed to the state, disorder or condition but does not yet experience or display clinical or subclinical symptoms of the state, disorder or condition, (2) inhibiting the state, disorder or condition, i.e., arresting, reducing or delaying the development of the disease or a relapse thereof (in case of maintenance treatment) or at least one clinical or subclinical symptom thereof, or (3) relieving or attenuating the disease, i.e., causing regression of the state, disorder or condition or at least one of its clinical or subclinical symptoms. 
     A “therapeutically effective amount” means the amount of a compound that, when administered to a mammal for treating a disease, is sufficient to effect such treatment for the disease. The “therapeutically effective amount” will vary depending on the compound, the disease and its severity and the age, weight, etc., of the mammal to be treated. 
     In this specification the term “alkyl” includes both straight and branched chain alkyl groups. References to individual alkyl groups such as “propyl” are specific for the straight chain version only and references to individual branched chain alkyl groups such as “isopropyl” are specific for the branched chain version only.

     The term “halo” refers to fluoro, chloro, bromo and iodo. 
     The term “haloalkyl” is used herein to refer to an alkyl group respectively in which one or more hydrogen atoms have been replaced by halogen (e.g. fluorine) atoms. 
     Examples of haloalkyl groups include fluoroalkyl groups such as —CHF 2 , —CH 2 CF 3 , or perfluoroalkylialkoxy groups such as —CF 3 , or —CF 2 CF 3 . 
     The term “heterocyclyl”, “heterocyclic” or “heterocycle” means a non-aromatic saturated or partially saturated monocyclic, fused, bridged, or Spiro bicyclic heterocyclic ring system(s). Monocyclic heterocyclic rings contain from about 3 to 12 (suitably from 3 to 7) ring atoms, with from 1 to 5 (suitably 1, 2 or 3) heteroatoms selected from nitrogen, oxygen or sulfur in the ring. Bicyclic heterocycles contain from 7 to 17 member atoms, suitably 7 to 12 member atoms, in the ring. Bicyclic heterocyclic(s) rings may be fused, spiro, or bridged ring systems.

As the skilled person would appreciate, any heterocycle may be linked to another group via any suitable atom, such as via a carbon or nitrogen atom. Suitably, the term “heterocyclyl”, “heterocyclic” or “heterocycle” will refer to 4, 5, 6 or 7 membered monocyclic rings as defined above. 
     The term “heteroaryl” or “heteroaromatic” means an aromatic mono-, bi-, or polycyclic ring incorporating one or more (for example 1-4, particularly 1, 2 or 3) heteroatoms selected from nitrogen, oxygen or sulfur. Examples of heteroaryl groups are monocyclic and bicyclic groups containing from five to twelve ring members, and more usually from five to ten ring members. The heteroaryl group can be, for example, a 5- or 6-membered monocyclic ring or a 9- or 10-membered bicyclic ring, for example a bicyclic structure formed from fused five and six membered rings or two fused six membered rings. Each ring may contain up to about four heteroatoms typically selected from nitrogen, sulfur and oxygen. Typically, the heteroaryl ring will contain up to 3 heteroatoms, more usually up to 2, for example a single heteroatom. In one embodiment, the heteroaryl ring contains at least one ring nitrogen atom. The nitrogen atoms in the heteroaryl rings can be basic, as in the case of an imidazole or pyridine, or essentially non-basic as in the case of an indole or pyrrole nitrogen. In general, the number of basic nitrogen atoms present in the heteroaryl group, including any amino group substituents of the ring, will be less than five. Suitably, the term “heteroaryl” or “heteroaromatic” will refer to 5 or 6 membered monocyclic heteroaryl rings as defined above. 
     Non-limiting examples of heteroaryl include fury!, pyrrolyl, thienyl, oxazolyl, isoxazolyl, imidazolyl, pyrazolyl, thiazolyl, isothiazolyl, oxadiazolyl, thiadiazolyl, triazolyl, tetrazolyl, pyridyl, pyridazinyl, pyrimidinyl, pyrazinyl, 1,3,5-triazenyl, benzofuranyl, indolyl, isoindolyl, benzothienyl, benzoxazolyl, benzimidazolyl, benzothiazolyl, indazolyl, purinyl, benzofurazanyl, quinolyl, isoquinolyl, quinazolinyl, quinoxalinyl, cinnolinyl, pteridinyl, naphthyridinyl, carbazolyl, phenazinyl, benzisoquinolinyl, pyridopyrazinyl, thieno[2,3-b]furanyl, 2H-furo[3,2-b]-pyranyl, 5H-pyrido[2,3-d]-o-oxazinyl, 1H-pyrazolo[4,3-d]-oxazolyl, 4H-imidazo[4,5-d]thiazolyl, pyrazino[2,3-d]pyridazinyl, imidazo[2,1-b]thiazolyl, imidazo[1,2-b][1,2,4]triazinyl. “Heteroaryl” also covers partially aromatic bi- or polycyclic ring systems wherein at least one ring is an aromatic ring and one or more of the other ring(s) is a non-aromatic, saturated or partially saturated ring, provided at least one ring contains one or more heteroatoms selected from nitrogen, oxygen or sulfur.

     or a pharmaceutically acceptable salt thereof. 
     The various functional groups and substituents making up the compounds of the present invention are typically chosen such that the molecular weight of the compound does not exceed 1000. More usually, the molecular weight of the compound will be less than 750, for example less than 700, or less than 650. 
     Suitable or preferred features of any compounds of the present invention may also be suitable features of any other aspect. 
     A suitable pharmaceutically acceptable salt of a compound of the invention is, for example, an acid-addition salt of a compound of the invention which is sufficiently basic, for example, an acid-addition salt with, for example, an inorganic or organic acid, for example hydrochloric, hydrobromic, sulfuric, phosphoric, trifluoroacetic, formic, citric or maleic acid. In addition a suitable pharmaceutically acceptable salt of a compound of the invention which is sufficiently acidic is an alkali metal salt, for example a sodium or potassium salt, an alkaline earth metal salt, for example a calcium or magnesium salt, an ammonium salt or a salt with an organic base which affords a physiologically-acceptable cation, for example a salt with methylamine, dimethylamine, trimethylamine, piperidine, morpholine or tris-(2-hydroxyethyl)amine. 
     Compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed “isomers”. Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers”. Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers”. When a compound has an asymmetric centre, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric centre and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture”. 
     The compounds of this invention typically possess one or more asymmetric centers; such compounds can therefore be produced as individual (R)- or (S)-stereoisomers or as mixtures thereof. Unless indicated otherwise, the description or naming of a particular compound in the specification and claims is intended to include both individual enantiomers, diastereoisomers and mixtures, racemic or otherwise, thereof. The methods for the determination of stereochemistry and the separation of stereoisomers are well-known in the art (see discussion in Chapter 4 of “Advanced Organic Chemistry”, 4th edition J. March, John Wiley and Sons, New York, 2001), for example by synthesis from optically active starting materials or by resolution of a racemic form. Some of the compounds of the invention may have geometric isomeric centres (E- and Z-isomers). It is to be understood that the present invention encompasses all optical, diastereoisomers and geometric isomers and mixtures thereof that possess Nrf2 activation activity. 
     The present invention also encompasses compounds of the invention as defined herein which comprise one or more isotopic substitutions. For example, H may be in any isotopic form, including  1 H,  2 H (D) and  3 H (T); C may be in any isotopic form including  12 C,  13 C, and  14 C; and O may be in any isotopic form, including  16 O and  18 O; and the like. 
     It is also to be understood that certain compounds of the invention may exist in solvated as well as unsolvated forms such as, for example, hydrated forms. It is to be understood that the invention encompasses all such solvated forms that possess Nrf2 activation activity. 
     It is also to be understood that certain compounds of the invention may exhibit polymorphism, and that the invention encompasses all such forms that possess Nrf2 activation activity. 
     Compounds of the invention may exist in a number of different tautomeric forms and references to compounds of the invention include all such forms. For the avoidance of doubt, where a compound can exist in one of several tautomeric forms, and only one is specifically described or shown, all others are nevertheless embraced by compounds of the invention. Examples of tautomeric forms include keto-, enol-, and enolate-forms, as in, for example, the following tautomeric pairs: keto/enol (illustrated below), imine/enamine, amide/imino alcohol, amidine/amidine, nitroso/oxime, thioketone/enethiol, and nitro/aci-nitro. 
     
       
         
         
             
             
         
       
     
     Compounds of the invention containing an amine function may also form N-oxides. A reference herein to a compound of the formula I that contains an amine function also includes the N-oxide. Where a compound contains several amine functions, one or more than one nitrogen atom may be oxidised to form an N-oxide. Particular examples of N-oxides are the N-oxides of a tertiary amine or a nitrogen atom of a nitrogen-containing heterocycle. N-Oxides can be formed by treatment of the corresponding amine with an oxidizing agent such as hydrogen peroxide or a per-acid (e.g. a peroxycarboxylic acid), see for example  Advanced Organic Chemistry , by Jerry March, 4 th  Edition, Wiley 
     Interscience, pages. More particularly, N-oxides can be made by the procedure of L. W. Deady ( Syn. Comm.  1977, 7, 509-514) in which the amine compound is reacted with m-chloroperoxybenzoic acid (MCPBA), for example, in an inert solvent such as dichloromethane. 
     The compounds of the invention may be administered in the form of a pro-drug which is broken down in the human or animal body to release a compound of the invention. A pro-drug may be used to alter the physical properties and/or the pharmacokinetic properties of a compound of the invention. A pro-drug can be formed when the compound of the invention contains a suitable group or substituent to which a property-modifying group can be attached. 
     Accordingly, the present invention includes those compounds of the formula I as defined hereinbefore when made available by organic synthesis and when made available within the human or animal body by way of cleavage of a pro-drug thereof. Accordingly, the present invention includes those compounds of the formula I that are produced by organic synthetic means and also such compounds that are produced in the human or animal body by way of metabolism of a precursor compound, that is a compound of the formula I may be a synthetically-produced compound or a metabolically-produced compound. 
     A suitable pharmaceutically acceptable pro-drug of a compound of the formula I is one that is based on reasonable medical judgement as being suitable for administration to the human or animal body without undesirable pharmacological activities and without undue toxicity. 
     Various forms of pro-drug have been described, for example in the following documents:

Roche (editor), “Bioreversible Carriers in Drug Design”, Pergamon Press, 1987.   

     The in vivo effects of a compound of the formula I may be exerted in part by one or more metabolites that are formed within the human or animal body after administration of a compound of the formula I. As stated hereinbefore, the in vivo effects of a compound of the formula I may also be exerted by way of metabolism of a precursor compound (a pro-drug). 
     It shall also be appreciated that compounds of the formula I may also be covalently linked (at any suitable position) to other groups such as, for example, solubilising moieties (for example, PEG polymers), moieties that enable them to be bound to a solid support (such as, for example, biotin-containing moieties), and targeting ligands (such as antibodies or antibody fragments). 
     Synthesis 
     In the description of the synthetic methods described below and in the referenced synthetic methods that are used to prepare the starting materials, it is to be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of the experiment and workup procedures, can be selected by a person skilled in the art. 
     It is understood by one skilled in the art of organic synthesis that the functionality present on various portions of the molecule must be compatible with the reagents and reaction conditions utilised. 
     Necessary starting materials may be obtained by standard procedures of organic chemistry. The preparation of such starting materials is described in conjunction with the following representative process variants and within the accompanying Examples. Alternatively, necessary starting materials are obtainable by analogous procedures to those illustrated which are within the ordinary skill of an organic chemist. 
     It will be appreciated that during the synthesis of the compounds of the invention in the processes defined below, or during the synthesis of certain starting materials, it may be desirable to protect certain substituent groups to prevent their undesired reaction. The skilled chemist will appreciate when such protection is required, and how such protecting groups may be put in place, and later removed. 
     For examples of protecting groups see one of the many general texts on the subject, for example, “Protecting groups in Organic Synthesis (3 rd  Ed), John Wiley &amp; Sons, NY (1999)”, T. Greene &amp; P. Wuts. Protecting groups may be removed by any convenient method described in the literature or known to the skilled chemist as appropriate for the removal of the protecting group in question, such methods being chosen so as to effect removal of the protecting group with the minimum disturbance of groups elsewhere in the molecule. 
     Thus, if reactants include, for example, groups such as amino, carboxy or hydroxy it may be desirable to protect the group in some of the reactions mentioned herein. 
     By way of example, a suitable protecting group for an amino or alkylamino group is, for example, an acyl group, for example an alkanoyl group such as acetyl, an alkoxycarbonyl group, for example a methoxycarbonyl, ethoxycarbonyl or tert-butoxycarbonyl group, an arylmethoxycarbonyl group, for example benzyloxycarbonyl, or an aroyl group, for example benzoyl. The deprotection conditions for the above protecting groups necessarily vary with the choice of protecting group. Thus, for example, an acyl group such as an alkanoyl or alkoxycarbonyl group or an aroyl group may be removed by, for example, hydrolysis with a suitable base such as an alkali metal hydroxide, for example lithium or sodium hydroxide. Alternatively, an acyl group such as a tert-butoxycarbonyl group may be removed, for example, by treatment with a suitable acid as hydrochloric, sulfuric or phosphoric acid or trifluoroacetic acid and an arylmethoxycarbonyl group such as a benzyloxycarbonyl group may be removed, for example, by hydrogenation over a catalyst such as palladium-on-carbon, or by treatment with a Lewis acid for example BF 3 .OEt 2 . A suitable alternative protecting group for a primary amino group is, for example, a phthaloyl group which may be removed by treatment with an alkylamine, for example dimethylaminopropylamine, or with hydrazine. 
     The person skilled in the art will recognise that the compounds of the invention may be prepared, in known manner, in a variety of ways. Compounds of formula I can be prepared by the methods given below, by the methods given in the experimental or by analogous methods. The routes described are merely illustrative of some of the methods that can be employed for the synthesis of compounds of formula I and the person skilled in the art will appreciate that the order of the reaction steps is not limited to those described. 
     It will also be appreciated that the assignment of nucleophile and electrophile is not limited to that described herein and in some cases it may be appropriate for the assignment to be reversed. Different approaches to synthetic chemistry strategy are described in “Organic Synthesis: The Disconnection Approach”, 2 nd  edition, S. Warren and P. Wyatt (2008). 
     The tetrahydroisoquinoline (THIQ) scaffold, wherein R 3  is bromo, may be constructed according to the route outlined in Scheme 1. 
     
       
         
         
             
             
         
       
     
     Variations at the R 3  position can be conveniently prepared from compounds of the invention or intermediates thereof wherein R 3  is bromo from chemistry well known in the art, as illustrated in Schemes 2 and 3. Compounds of the invention wherein R 3  is H, or CI may be prepared from intermediates where R 3  is Br according to the method outlined in Scheme 2. 
     
       
         
         
             
             
         
       
     
     As shown in Scheme 3, the conversion of the bromo R 3  substituent into a suitable boronate or boronic acid allows preparation of the fluoro and trifluoro derivatives. The bromo can be converted to an alkyl group through reaction with a suitable alkyl boronate with a suitable palladium catalyst; for example, where alkyl is methyl, a suitable boronate is 2,4,6-trimethyl-1,3,5,2,4,6-trioxatriborinane and a suitable palladium catalyst is Pd(dppf)Cl 2 . Compounds wherein R 3  is cyano can be prepared from bromo derivatives by treatment with a cyanating agent such as Zn(CN) 2  with a palladium catalyst such as Pd(PPh 3 ) 4 .

     General Method A 
     In a typical synthetic procedure the phthalimide, when used as a protecting group, is removed using typical reagents (e.g. hydrazine) and the amine is reacted with appropriate reagents to install the desired substitution NR 4 R 5 . A third step involves installation of the required ether through conventional methods such as alkylation with an alkyl halide or activated alcohol (e.g. mesylate, triflate) or Mitsunobu reaction using reagents such as DBAD or DEAD and an appropriate phosphine. The Boc protecting group is then removed typically by treatment with HCl. The L 1 X 1 (R 7 )L 2 X 2 (CO 2 R)R 10  group may be introduced from the appropriately substituted and protected bis-acid derivative; ideally where one of the acid groups is activated for reaction with the amine of the tetrahydroisoquinoline (THIQ) scaffold and the other acid group is suitably protected, for example as a benzyl or dimethoxybenzyl ester, or by ring opening of an appropriate cyclic anhydride, or by reaction with an acid chloride. Typical amide coupling reagents such as HATU are used to effect acid activation. 
     
       
         
         
             
             
         
       
     
     In a penultimate step, the protecting group is removed by the appropriate methodology such as hydrolysis, hydrogenolysis, strong acid such as HCl or TFA or lewis acid such as BBr 3  to give the carboxylic acid. In a final step the carboxylic acid is converted to a primary, secondary or tertiary amide using amide coupling reactions and agents well known in the art, such as HATU and 1,1′-carbonyldiimidazole (CDI). 
     General Method B 
     
       
         
         
             
             
         
       
     
     In a further typical procedure, the order of steps can be altered compared with general method A. The required ether is installed in a first step, again through conventional methods as described in the above General Method A. The phthalimide protecting group is removed in a second step and the amine is reacted with appropropriate reagents to install the desired substitution NR 4 R 5 . The Boc protecting group is then removed and the L 1 X 1 (R 7 )L 2 X 2 (CO 2 R)R 10  group may then be introduced in a fifth step. The final step comprises removal of the carboxylic acid protecting group as described in the above general methods. 
     Syntheses of example carboxylic acid compounds are described in the co-pending application PCT/GB2019/053012 (WO2020/084300). 
     General Method C 
     
       
         
         
             
             
         
       
     
     In a further typical procedure the L 1 X 1 (R 7 )L 2 N(R)R 10  group may be introduced from the appropriately substituted and protected mono-acid derivative; ideally where the acid group is activated for reaction with the amine of the tetrahydroisoquinoline (THIQ) scaffold and the amine group is suitably protected, for example as a tert-butoxycarbonyl, or by reaction with an appropriate acid chloride. 
     Pharmaceutical Compositions 
     The compounds of the invention will normally, but not necessarily, be formulated into pharmaceutical compositions prior to administration to a patient. Therefore, according to a further aspect of the invention there is provided a pharmaceutical composition which comprises a compound of the invention as defined hereinbefore, or a pharmaceutically acceptable salt thereof, and one or more pharmaceutically acceptable excipients, diluent or carrier. 
     The pharmaceutical compositions of the invention may be prepared and packaged in bulk form wherein a safe and effective amount of a compound of the invention can be extracted and then given to the patient such as with powders or syrups. Alternatively, the pharmaceutical compositions of the invention may be prepared and packaged in unit dosage form wherein each physically discrete unit contains a safe and effective amount of a compound of the invention. When prepared in unit dosage form, the pharmaceutical compositions of the invention typically contain from 1 mg to 1000 mg. 
     The compositions of the invention may be in a form suitable for oral use (for example as tablets, capsules, caplets, pills, troches, powders, syrups, elixirs, suspensions, solutions, emulsions, sachets, and cachets), for topical use (for example as creams, ointments, lotions, solutions, pastes, sprays, foams, and gels), for transdermal administration such as via transdermal patches, for administration by inhalation (for example as a dry powders, aerosols, suspensions, and solutions), for administration by insufflation (for example as a finely divided powder) or for parenteral administration (for example as a sterile aqueous or oily solution for intravenous, subcutaneous, intramuscular, intraperitoneal or intramuscular dosing or as a suppository for rectal dosing). 
     As used herein, “pharmaceutically-acceptable excipient” means a pharmaceutically acceptable material, composition or vehicle involved in giving form or consistency to the pharmaceutical composition. Each excipient must be compatible with the other ingredients of the pharmaceutical composition when commingled such that interactions which would substantially reduce the efficacy of the compound of the invention when administered to a patient and interactions which would result in pharmaceutical compositions that are not pharmaceutically acceptable are avoided. In addition, each excipient must be of sufficiently high purity to render it pharmaceutically-acceptable. 
     Suitable pharmaceutically-acceptable excipients will vary depending upon the particular dosage form chosen. In addition, suitable pharmaceutically-acceptable excipients may be chosen for a particular function that they may serve in the composition. For example, certain pharmaceutically-acceptable excipients may be chosen for their ability to facilitate the production of uniform dosage forms. Certain pharmaceutically-acceptable excipients may be chosen for their ability to facilitate the production of stable dosage forms. Certain pharmaceutically-acceptable excipients may be chosen for their ability to facilitate the carrying or transporting of the compound or compounds of the invention once administered to the patient from one organ, or portion of the body, to another organ, or portion of the body. Certain pharmaceutically-acceptable excipients may be chosen for their ability to enhance patient compliance. 
     Suitable pharmaceutically-acceptable excipients include the following types of excipients: diluents, fillers, binders, disintegrants, lubricants, glidants, granulating agents, coating agents, wetting agents, solvents, co-solvents, suspending agents, emulsifiers, sweeteners, flavoring agents, flavor masking agents, coloring agents, anticaking agents, humectants, chelating agents, plasticizers, viscosity increasing agents, antioxidants, preservatives, stabilizers, surfactants, and buffering agents. The person skilled in the art will appreciate that certain pharmaceutically-acceptable excipients may serve more than one function and may serve alternative functions depending on how much of the excipient is present in the formulation and what other ingredients are present in the formulation. 
     Persons skilled in the art possess the knowledge and skill to enable them to select suitable pharmaceutically-acceptable excipients in appropriate amounts for use in the invention. In addition, there are a number of resources that are available to the skilled artisan which describe pharmaceutically-acceptable excipients and may be useful in selecting suitable pharmaceutically-acceptable excipients. Examples include Remington&#39;s Pharmaceutical Sciences (Mack Publishing Company), The Handbook of Pharmaceutical Additives (Gower Publishing Limited), and The Handbook of Pharmaceutical Excipients (the American Pharmaceutical Association and the Pharmaceutical Press). 
     The pharmaceutical compositions of the invention are prepared using techniques and methods known to those skilled in the art. Some of the methods commonly used in the art are described in Remington&#39;s Pharmaceutical Sciences (Mack Publishing Company). 
     The amount of active ingredient that is combined with one or more excipients to produce a single dosage form will necessarily vary depending upon the host treated and the particular route of administration. For example, a formulation intended for oral administration to humans will generally contain, for example, from 0.5 mg to 0.5 g of active agent (more suitably from 0.5 to 100 mg, for example from 1 to 30 mg) compounded with an appropriate and convenient amount of excipients which may vary from about 5 to about 98 percent by weight of the total composition. 
     The size of the dose for therapeutic or prophylactic purposes of a compound of the formula I will naturally vary according to the nature and severity of the conditions, the age and sex of the animal or patient and the route of administration, according to well-known principles of medicine. 
     In using a compound of the invention for therapeutic or prophylactic purposes it will generally be administered so that a daily dose in the range, for example, 0.1 mg/kg to 75 mg/kg body weight is received, given if required in divided doses. In general, lower doses will be administered when a parenteral route is employed. Thus, for example, for intravenous or intraperitoneal administration, a dose in the range, for example, 0.1 mg/kg to 30 mg/kg body weight will generally be used. Similarly, for administration by inhalation, a dose in the range, for example, 0.05 mg/kg to 25 mg/kg body weight will be used. Oral administration may also be suitable, particularly in tablet form. Typically, unit dosage forms will contain about 0.5 mg to 0.5 g of a compound of this invention. 
     Routes of Administration 
     The compounds of the invention or pharmaceutical composition comprising the active compound may be administered to a subject by any convenient route of administration, whether systemically/peripherally or topically (i.e. at the site of desired action). 
     Routes of administration include, but are not limited to, oral (e.g., by ingestion); buccal; sublingual; transdermal (including, e.g., by a patch, plaster, etc.); transmucosal (including, e.g., by a patch, plaster, etc.); intranasal (e.g., by nasal spray); ocular (e.g., by eyedrops); pulmonary (e.g., by inhalation or insufflation therapy using, e.g., via an aerosol, e.g., through the mouth or nose); rectal (e.g., by suppository or enema); vaginal (e.g., by pessary); parenteral, for example, by injection, including subcutaneous, intradermal, intramuscular, intravenous, intraarterial, intracardiac, intrathecal, intraspinal, intracapsular, subcapsular, intraorbital, intraperitoneal, intratracheal, subcuticular, intraarticular, subarachnoid, and intrasternal; by implant of a depot or reservoir, for example, subcutaneously or intramuscularly.

     EXAMPLES 
     General Procedures: 
     Methods for preparing the compounds of this invention are illustrated in the following Examples. Starting materials are made according to procedures known in the art, or as illustrated herein, or are available commercially. Commercial reagents were used without further purification. Where no reaction temperature is included, the reaction was performed at ambient temperature which is typically 18-27° C. 
     Where compounds described in the invention are characterized by  1 H NMR spectroscopy, spectra were recorded on 500 MHz Bruker, 400 MHz Bruker, 250 MHz Bruker, 300 MHz JEOL or 400 MHz JEOL instruments. Where no temperature is included, the spectra were recorded at ambient temperature. Chemical shift values are expressed in parts per million (ppm). Where NMR spectra are complex due to the presence of interconverting isomers, approximate partial integrations of signals are reported, or characterisation for the major isomer only is reported. The following abbreviations are used for the multiplicity of the NMR signals: s=singlet, b=broad, t=triplet, q=quartet, m=multiplet, d=doublet. 
     Analytical LCMS 
     Where compounds described in the invention are characterized by LCMS data, retention time and molecular weight are determined using the methods listed in the table below. In cases where compounds of the invention appear as slowly interconverting stereoisomers, multiple retention times are reported.

     Preparative HPLC 
     Preparative HPLC was performed using a variety of preparative systems with variable wavelength UV detection or Mass Directed AutoPrep (MDAP) systems as listed in the table below. Collection was triggered by UV, MS or a combination of the two. The UV detection was at a selected wavelength generally 210 nm, 230 nm or 280 nm. Mass spectra were recorded on a mass spectrometer using an alternate-scan positive and negative electrospray ionization.

     KEAP1 Kelch Fluorescence Polarization (FP) Assay Method 
     Inhibition of the Kelch domain-NRF2 interaction was determined using a fluorescence polarization-based competition assay in a black 384-well microplate. Compounds were tested at a starting concentration of 10 μM serially diluted 1:3 to generate a 12-point dose response curve on the Biomek FX robot. Each well contained 2 nM FITC-labelled NRF 2  peptide (FITC-LDEETGEFL-NH2) and 25 nM human KEAP1 (N-term, residues 321-609) enzyme in a final volume of 20 μL of assay buffer (50 mM Tris-HCl pH 8.0, 100 mM NaCl, 5 mM MgCl 2 , 0.005% Tween-20, 0.005% BSA, 0.5% DMSO) in the presence of varying concentrations of test compound. Unlabelled peptide (LDEETGEFL-NH2) at 50 μM (negative control) and 0.5% DMSO (positive control) was used to determine the assay window. 
     After 1 h at room temperature, fluorescence polarization (excitation 470 nm/emission 530 nm) was measured using an Envision plate reader. IC 50  values were determined by fitting the data to a four parameter logistic fit using XLfit or XE Runner within ActivityBase. The assay limit is such that compounds below 10 nM cannot be differentiated. IC 50  values for the Example compounds are shown in Table 2.

     Beas2B NQO1 mRNA Cell Based Assay 
     The up regulation of the NRF2 mediated gene NAD(P)H:quinone acceptor oxidoreductase 1 (NQO1) was measured using the following assay method: BEAS-2B cells (ATCC CRL-9609) were plated in 96-well clear plates at 20,000 cells/well in 75 μL of cell culture media and incubated overnight (37° C., 5% CO 2 ). On day 2, 25 μL of compound or controls were added to the cells for 24 h. On day 3, the medium was aspirated from the plate and the Cells-to-CT™ 1-Step TaqMan® Kit (Ambion A25603) was used to perform expression analysis directly from cultured cells without RNA purification according to the manufacturer&#39;s instructions. 
     Briefly, cells were washed with ice cold PBS and 22.5 μL of room-temperature DNase/Lysis solution was added to the cells and incubated at room temperature for 5 minutes. To stop the reaction, 2.25 μL of stop solution was added to the cell lysate. The samples were diluted 1:5 using nuclease free water and 2.5 μL transferred into the PCR plate. Real-time PCR was performed using the C-1000 Thermal Cycler (Bio-Rad) using human beta actin as the internal control. The cDNA was amplified with a specific primer for NQO 1  using the 1-step RT-PCR master mix (Ambion Cells-to-CTTM 1-Step TaqMan® Kit A25603). The primers/probes sets that were used for amplification of cDNA were obtained from TaqMan Gene Expression Assays (Applied Biosystems). The comparative CT (ΔΔCT) relative quantification method was used to calculate the relative mRNA level of the target gene NQO1 as described in the Applied Biosystems Chemistry Guide. The data are expressed as an increase in target gene mRNA compared to vehicle (0.1% DMSO) control and the EC 50  values were determined by fitting the data to a four parameter logistic fit using XLfit or XE Runner within ActivityBase. EC 50  values for the Example compounds are shown in Table 3.

     PK/PD Method 
     Male Wistar Han rats (Charles River labs) were administered the test item orally or intravenously at the designated dose concentration. The intravenous dose was administered as a slow bolus via the tail vein. The oral formulation was administered by gastric gavage into the stomach. Actual dose times were recorded. 
     At the designated time points, 2×0.25 mL blood samples were collected into K 2 EDTA blood tubes via the tail vein. The collected blood samples were then either centrifuged for plasma or decanted into the 1.5 mL PCR RNAlater tubes containing 650 μL of RNAlater. 
     Immediately following collection, blood samples were placed on wet ice. As soon as practically possible the 0.25 mL blood samples in K 2 EDTA were centrifuged (+4° C., 1500 g, 10 min) and the resulting plasma stored in appropriately labelled polypropylene tubes in a freezer set to maintain a temperature of −80° C. until determination of plasma pharmacokinetics. The additional 0.25 mL blood samples in the 1.5 mL PCR RNAlater tubes containing 650 μL of RNAlater were stored in a refrigerator at 4° C. until determination of blood pharmacodynamics. 
     Following the last sample collection each animal was sacrificed by anesthetic overdose by IP injection of Pentobarbitone Na as soon as practically possible and death was confirmed by cervical dislocation. 
     The lungs from each animal were removed and divided into 4 equal pieces immediately after extraction. The first two sections of lung (labelled left and right) were placed in 5 mL RNAlater tissue protect tube containing 5 mL RNAlater stabilisation reagent and stored at 4° C. to allow RNA stabilization (PD analysis). The remaining two sections (labelled left and right) were weighed and snap frozen by immersion in liquid nitrogen in polypropylene tubes (PK analysis). 
     The liver was also collected from each animal. Six representative pieces (of a similar size to the lung pieces) from different areas (no more than 0.5 cm thickness) were collected. Four pieces (no more than 0.5 cm thickness) were placed in two separate (two pieces per tube) 5 mL RNAlater tissue protect tubes containing 5 mL RNAlater stabilisation reagent (tissue sections were completely submerged into the RNA later solution) and stored at 4° C. (PD analysis). The remaining two pieces were weighed and snap frozen by immersion in liquid nitrogen in separate polypropylene tubes (a maximum of 0.5 g per tube, PK analysis). 
     In some studies, the heart, spleen and brain were also collected from each animal. These tissues were sectioned into four equal sized pieces and two pieces placed in a single 5 mL RNA later tissue protect tube containing 5 mL RNAlater stabilisation reagent and stored at 4° C. The remaining two pieces were weighed and placed individually into polypropylene tubes and snap frozen by immersion in liquid nitrogen. 
     Study sample tubes containing RNAlater RNA Stabilisation Reagent were stored at ca +4° C. to allow RNA stabilisation reagent to perfuse the tissue. Sections snap frozen were stored in a freezer set to maintain a temperature of −80° C. 
     PK study samples were quantified using a method based on protein precipitation and LC-MS/MS analysis. Prior to analysis defrosted tissue samples were weighed and homogenised following the addition of HPLC grade water using an Omni-Prep Bead Ruptor (Omni Inc., Kennesaw, Ga.) at 4° C. Plasma and tissue homogenate samples were extracted using protein precipitation with acetonitrile acidified with 0.1% formic acid containing internal standard(s). Samples were mixed and centrifuged at 4000 rpm at 4° C. for 30 minutes to remove precipitated proteins, and the supernatant diluted appropriately with HPLC grade water in a 96-well plate. Representative aliquots of plasma and tissue homogenates were assayed for test item by LC-MS/MS using a Waters Xevo TQ-S (Waters, Elstree, UK) against matrix matched calibration curves and quality control standards. The standards were prepared by spiking aliquots of control plasma and tissue homogenate with the test item and extracted as described for the experimental samples. 
     RNA extraction and real-time PCR analysis for NQO 1  gene expression in in-vivo PD studies was performed as detailed below. 
     Total RNA was isolated using RNeasy plus mini RNA isolation kit (Qiagen) or Mouse RiboPureTM-Blood RNA Isolation Kit (ThermoFisher Scientific) according to the manufacturer&#39;s instructions and quantified using an Agilent RNA 6000 Nano instrument. Real-time PCR was performed using the C-1000 Thermal Cycler (Bio-Rad) using rat beta actin as the internal control. The cDNA was amplified with specific primer for NQO1/Nqo1 using universal master mix (Applied Biosystems). The primers/probes sets used for amplification of cDNA were obtained from TaqMan Gene Expression Assays (Applied Biosystems). The comparative CT (bACT) relative quantification method is used to calculate the relative mRNA level of the target gene NQO1 as described in the Applied Biosystems Chemistry Guide. The data is expressed as an increase in target gene mRNA compared to vehicle control treated for each tissue type.
