Abstract
Description
[0001] NOVEL FERROPTOSIS INHIBITORSField of the invention The present invention relates to ferrostatin-1 derivative compounds, or pharmaceutically acceptable salts thereof, as defined herein, that are useful for inhibiting undesired cell deathoccurring in diseases associated with ferroptosis and / or oxytosis such as liver disease, chronickidney disease, lung disease, ocular surface diseases, wound healing, multiple organ dysfunction syndrome, neurological disease, acute renal failure, ischemia-reperfusion injury, sepsis, iron toxicity, prevention of transplant rejection, iron metabolism-related disease, and genetic disorders of GPX4. The invention also provides compositions containing a pharmaceutically acceptable carrier and one or more compounds from the invention methods of prevention and / or treatment of such diseases. Background of the invention Cell death is crucial for normal development, homeostasis, and the prevention of hyperproliferative diseases such as cancer. It was once thought that almost all regulated cell death in mammalian cells resulted from the activation of caspase-dependent apoptosis. This view has been challenged by the discovery of several regulated non-apoptotic cell death pathways activated in specific disease states. Regulated necrosis is defined as a geneticallycontrolled cell death process that eventually results in cellular leakage, and is morphologicallycharacterized by cytoplasmic granulation, as well as organelle and / or cellular swelling.Ferroptosis is one recognized form of regulated necrosis, and its hallmark is the production ofiron-dependent lipophilic reactive oxygen species (ROS). Cell membrane rupture during ferroptotic cell death is characterized by hydrogen abstraction and oxygenation of poly unsaturated fatty acids (PUFAs) of phospholipids (PLs), which is catalysed by redox-active iron. This subsequently leads to cell death due to disruption of membrane stability and the accumulation of lipid hydroperoxides to lethal levels. Although the process of lipid peroxidation has been linked to several regulated cell death modalities, ferroptosis is exclusively driven by excessive lipid peroxidation. Oxidative damage of PUFA-PLs can be initiated either through non-enzymatic free-radical chain reactions involving Fenton chemistry or enzyme-mediated processes catalysed by iron-dependent lipoxygenases (LOXs) or cytochrome P450oxidoreductase (POR). In addition to ferroptosis, glutamine- and oxidative stress induced celldeath are inhibited by iron chelation. In line with this, iron-dependent neuronal cell death is blocked by metal protein-attenuating compounds (e.g. clioquinol) and iron chelators (e.g. deferoxamine), which are being explored for the treatment of neurodegenerative diseases. Another type of regulated necrosis is oxytosis which is also induced when the Xc- Cys / Gluantiporter is inhibited through an excess of the neurotransmitter glutamine; the latter process is often designated as excitotoxicity in neuronal cells. Because of the clear mechanistic overlaps between oxytosis and ferroptosis it is likely that the use of modulators of ferroptosis in disease will target the same disease processes which are associated with oxytosis. Disease processes where undesired ferroptosis and / or oxytosis occur are typically disorders where an oxidative stress factor is involved such as for example in several neurodegenerative diseases,liver-, cardiac- and kidney-ischaemia – reperfusion injury, stroke, sepsis, diabetes andepilepsy. Oxidative stress due to iron overload is for example highly relevant in organs accumulating iron such as the brain, kidney and liver. Several compounds have been described in the art which are able to inhibit ferroptosis such as for example WO2013 / 152039,Skouta R. et al (2014) J. Am. Chem. Soc. 136, 4551-4556). The prior art highlights theimportance of the ethyl-ester in the maintenance of the potency of the first-in-class compound ferroptosis inhibitor molecule (designated as Ferrostatin-1) and there have been suggestions for chain modifications of the ester for generating improved molecules. Indeed, the latter reference also teaches that esters modified to amides and sulfonamides at the same position have a lower EC50. It has also been suggested that improved pharmacokinetic variants of Ferrostatin-1 could be ester analogues. It would be desirable to generate additional compounds that can inhibit or reduce ferroptosis, in particular compounds with an improved physicochemical and / or pharmacokinetic profile. There is a need for small molecules that use ferroptosis and / or oxytosis as their target, have strong selectivity, have properties that are amenable to develop them as pharmaceuticals, such as high solubility, and have significant efficacy for the treatment of the ferroptosis and / or oxytosis related diseases. Summary of the invention The present invention is based on the unexpected finding that at least one of the above- mentioned objectives can be attained by small molecules. The present invention provides compounds which have surprisingly found to be potent inhibitors of ferroptosis and / or oxytosis, while also displaying excellent solubility; in addition,they show very potent in vitro anti-ferroptotic activity in the low nanomolar range, good radical-trapping ability, and medium to high human microsomal stability. In view thereof, these compounds can be used to treat diseases where an excess of ferroptosis and / or oxytosisoccurs. Further, the inventors have found that for some compounds show very good plasmaavailability after IV administration, making them particularly suitable for therapeutic use by parenteral administration.

In the present invention the potency of a compound inhibiting (or reducing) ferroptosis and / oroxytosis are determined in (bio)chemical antioxidant activity assays, in vitro assays. Typically, FENIX assay is used to quantify radical trapping antioxidant activity in phospholipid bilayersto predict anti-ferroptotic potency of lipophilic antioxidants in cells. Typically, in vitro assaysare used to measure the potency of a candidate compound. Examples of suitable in vitro assays are cellular assays. One non-limiting example of an assay involves the use of the IMR-32 neuroblastoma cell line. The latter is stimulated to enter ferroptosis upon stimulation with10µM erastin, a documented ferroptosis inducer (see for example Dixon et al (2012) Cell 149,1060-1072 and ferroptosis inhibitors are evaluated for the prevention of erastin induced ferroptosis. Another assay involves the use of ML162-induced ferroptosis in HT1080 human fibrosarcoma cells. Yet another assay is based on the glutamate-induced cell death in the hippocampal cell line HT22 and ferroptosis / oxytosis inhibitors are evaluated for the preventionof cell death (see Henke N. et al (2013) Cell Death and Disease 4, e470). Still another assayis based on the sorafenib induced cell death (described to be iron dependent cell death) inhepatocellular carcinoma cells and ferroptosis inhibitors are evaluated for the prevention ofcell death (see Louandre C. et al (2013) Int. J. Cancer 133, 1732). The calculated potency ofa compound inhibiting ferroptosis and / or oxytosis is typically depicted as an IC50 value.Examples of suitable in vivo assays are typically pre-clinical disease models of for examplemice for the diseases benefiting the application of ferroptosis and / or oxytosis inhibitors, as described herein.One non-limiting example of an in vivo assay is based on inducing organ injury by iron overloador using liver, kidney, lung, brain or intestine-specific Gpx4-deficient mouse lines andferroptosis inhibitors are evaluated based on the level of reduction in plasma injury biomarkersLDH, CK, AST and ALT, and body temperature (see Van Coillie et al. (2022) Nat Comm 13:1046). The compounds of this invention can be administered as the sole pharmaceutical agent or in combination with one or more other pharmaceutical agents where the combination causes no unacceptable adverse effects. The present invention relates also to such combinations. For example, the compounds of this invention can be combined with known therapeutic agents forthe treatment of diseases mentioned herein, as well as with admixtures and combinationsthereof. Particularly preferred combinations are necroptosis inhibitors (e.g. necrostatin-1) andferroptosis inhibitors. Examples of these combinations are described in Linkermann et al 2014.The compounds of the invention may be in the form of salts, preferably pharmaceutically acceptable salts, as generally described below. Some preferred, but non-limiting examples of suitable pharmaceutically acceptable organic and / or inorganic acids are as hydrochloric acid, trifluoroacetic acid (or triflate), hydrobromic acid, sulfuric acid, nitric acid, acetic acid and citric acid, as well as other pharmaceutically acceptable acids known per se (for which reference is made to the prior art referred to below). When the compounds of the invention contain an acidic group as well as a basic group the compounds of the invention may also form internal salts, and such compounds are within the scope of the invention. When the compounds of the invention contain a hydrogen-donating heteroatom (e.g. NH), the invention also covers salts and / or isomers formed by transfer of said hydrogen atom to a basic group or atom within the molecule. Pharmaceutically acceptable salts of the compounds of formula (I) and any subgroup thereof include the acid addition and base salts thereof. Suitable acid addition salts are formed from acids which form non-toxic salts. Examples include the acetate, adipate, aspartate, benzoate, besylate, bicarbonate / carbonate, bisulfate / sulfate, borate, camsylate, citrate, cyclamate, edisylate, esylate, formate, fumarate, gluceptate, gluconate, glucuronate, hexafluorophosphate, hibenzate, hydrochloride / chloride, hydrobromide / bromide, hydroiodide / iodide, isethionate, lactate, malate, maleate, malonate, mesylate, methylsulphate, naphthylate, 2-napsylate, nicotinate, nitrate, orotate, oxalate, palmitate, pamoate, phosphate / hydrogen phosphate / dihydrogen phosphate, pyroglutamate, saccharate, stearate, succinate, tannate, tartrate, tosylate, trifluoroacetate (or triflate) and xinofoate salts. Suitable base salts are formed from bases which form non-toxic salts. Examples include the aluminium, arginine, benzathine, calcium, choline, diethylamine, diolamine, glycine, lysine, magnesium, meglumine, olamine, potassium, sodium, tromethamine and zinc salts. Hemisalts of acids and bases may also be formed, for example, hemisulphate and hemicalcium salts. For a review on suitable salts, see Handbook of Pharmaceutical Salts: Properties, Selection, and Use by Stahl and Wermuth (Wiley-VCH, 2002), incorporated herein by reference. The compounds of the invention may exist in a continuum of solid states ranging from fully amorphous to fully crystalline. The term 'amorphous' refers to a state in which the material lacks long range order at the molecular level and, depending upon temperature, may exhibitthe physical properties of a solid or a liquid. Typically, such materials do not give distinctive X-ray diffraction patterns and, while exhibiting the properties of a solid, are more formally described as a liquid. Upon heating, a change from solid to liquid properties occurs which is characterized by a change of state, typically second order ('glass transition'). The term 'crystalline' refers to a solid phase in which the material has a regular ordered internal structure at the molecular level and gives a distinctive X-ray diffraction pattern with defined peaks. Such materials when heated sufficiently will also exhibit the properties of a liquid, but the change from solid to liquid is characterized by a phase change, typically first order ('melting point'). Pharmaceutically acceptable salts of compounds of formula (I) may be prepared by one or more of these methods: (i) by reacting the compound of formula (I) with the desired acid; (ii) by reacting the compound of formula (I) with the desired base;(iii) by removing an acid- or base-labile protecting group from a suitable precursor of thecompound of formula (I) or by ring-opening a suitable cyclic precursor, for example, a lactone or lactam, using the desired acid; or (iv) by converting one salt of the compound of formula (I) to another by reaction with an appropriate acid or by means of a suitable ion exchange column. All these reactions are typically carried out in solution. The salt may precipitate from solution and be collected by filtration or may be recovered by evaporation of the solvent. The degree of ionization in the salt may vary from completely ionized to almost non-ionized. The compounds of the invention may also exist in unsolvated and solvated forms. The term 'solvate' is used herein to describe a molecular complex comprising the compound of the invention and one or more pharmaceutically acceptable solvent molecules, for example, ethanol. The term 'hydrate' is employed when said solvent is water. A currently accepted classification system for organic hydrates is one that defines isolatedsite, channel, or metal-ion coordinated hydrates - see Polymorphism in Pharmaceutical Solidsby K. R. Morris (Ed. H. G. Britain, Marcel Dekker, 1995), incorporated herein by reference. Isolated site hydrates are ones in which the water molecules are isolated from direct contactwith each other by intervening organic molecules. In channel hydrates, the water moleculeslie in lattice channels where they are next to other water molecules. In metal-ion coordinated hydrates, the water molecules are bonded to the metal ion. When the solvent or water is tightly bound, the complex will have a well-defined stoichiometry independent of humidity. When, however, the solvent or water is weakly bound, as in channelsolvates and hygroscopic compounds, the water / solvent content will be dependent onhumidity and drying conditions. In such cases, non-stoichiometry will be the norm. Also included within the scope of the invention are multi-component complexes (other than salts and solvates) wherein the drug and at least one other component are present in stoichiometric or non-stoichiometric amounts. Complexes of this type include clathrates (drug- host inclusion complexes) and co-crystals. The latter are typically defined as crystalline complexes of neutral molecular constituents which are bound together through non-covalentinteractions but could also be a complex of a neutral molecule with a salt. Co-crystals may beprepared by melt crystallization, by recrystallization from solvents, or by physically grindingthe components together - see Chem Commun, 17, 1889-1896, by O. Almarsson and M. J.Zaworotko (2004), incorporated herein by reference. For a general review of multi-component complexes, see J Pharm Sci, 64 (8), 1269-1288, by Haleblian (August 1975), incorporated herein by reference. The compounds of the invention may also exist in a mesomorphic state (mesophase or liquid crystal) when subjected to suitable conditions. The mesomorphic state is intermediate between the true crystalline state and the true liquid state (either melt or solution). Mesomorphism arising as the result of a change in temperature is described as 'thermotropic' and that resulting from the addition of a second component, such as water or another solvent, is described as 'lyotropic'. Compounds that have the potential to form lyotropic mesophases are described as 'amphiphilic' and consist of molecules which possess an ionic (such as - COO-Na+, -COO-K+, or -SO3-Na+) or non-ionic (such as -N-N+(CH3)3) polar head group. For more information, see Crystals and the Polarizing Microscope by N. H. Hartshorne and A. Stuart, 4thEdition (Edward Arnold, 1970), incorporated herein by reference. All references to compounds of formula (I) or any subgroups thereof include references to salts, solvates, multi-component complexes and liquid crystals thereof and to solvates, multi- component complexes and liquid crystals of salts thereof. The compounds of the invention include compounds of formula (I) or any subgroups thereof as hereinbefore defined, including all polymorphs and crystal habits thereof, prodrugs and isomers thereof (including optical, geometric and tautomeric isomers) as hereinafter defined and isotopically-labelled compounds of formula (I). In addition, although generally, with respect to the salts of the compounds of the invention, pharmaceutically acceptable salts are preferred, it should be noted that the invention in its broadest sense also included non-pharmaceutically acceptable salts, which may for example be used in the isolation and / or purification of the compounds of the invention. A further related aspect of the present invention provides a pharmaceutical composition comprising a compound of formula (I) or a stereoisomer, or tautomer thereof, and a pharmaceutically acceptable carrier. The term “pharmaceutically acceptable” as used herein is consistent with the art and means compatible with the other ingredients of a pharmaceutical composition and not deleterious to the recipient thereof. As used herein, “carrier” or “excipient” includes any and all solvents, diluents, buffers (such as, e.g., neutral buffered saline or phosphate buffered saline), solubilisers, colloids, dispersion media, vehicles, fillers, chelating agents (such as, e.g., EDTA or glutathione), amino acids (such as, e.g., glycine), proteins, disintegrants, binders, lubricants, wetting agents, emulsifiers, sweeteners, colorants, flavourings, aromatisers, thickeners, agents for achieving a depot effect, coatings, antifungal agents, preservatives, antioxidants, tonicity controlling agents, absorption delaying agents, and the like. The use of such media and agents for pharmaceutical active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active substance, its use in the therapeutic compositions may be contemplated. Illustrative, non-limiting carriers for use in formulating the pharmaceutical compositions include, for example, oil-in-water or water-in-oil emulsions, aqueous compositions with or without inclusion of organic co-solvents suitable for intravenous (IV) use, liposomes or surfactant-containing vesicles, microspheres, microbeads and microsomes, powders, tablets, capsules, suppositories, aqueous suspensions, aerosols, and other carriers apparent to one of ordinary skill in the art. Pharmaceutical compositions as intended herein may be formulated for essentially any route of administration, such as without limitation, oral administration (such as, e.g., oral ingestion or inhalation), intranasal administration (such as, e.g., intranasal inhalation or intranasal mucosal application), parenteral administration (such as, e.g., subcutaneous, intravenous (I.V.), intramuscular, intraperitoneal or intrasternal injection or infusion), transdermal or transmucosal (such as, e.g., oral, sublingual, intranasal) administration, topical administration, rectal, vaginal or intra-tracheal instillation, and the like. In this way, the therapeutic effects attainable by the methods and compositions can be, for example, systemic, local, tissue-specific, etc., depending on the specific needs of a given application.In preferred embodiments, the compound or the pharmaceutical composition as taught herein is administered parenterally. More preferably, the compound or the pharmaceutical composition as taught herein is administered intravenously, for example by infusion. The dosage or amount of the agent as taught herein, optionally in combination with one or more other active compounds to be administered, depends on the individual case and is, as is customary, to be adapted to the individual circumstances to achieve an optimum effect. Thus, the unit dose and regimen depend on the nature and the severity of the disorder to be treated, and also on factors such as the species of the subject, the sex, age, body weight, general health, diet, mode and time of administration, immune status, and individual responsiveness of the human or animal to be treated, efficacy, metabolic stability and duration of action of the compounds used, on whether the therapy is acute or chronic or prophylactic, or on whether other active compounds are administered in addition to the agent of the invention. In order to optimize therapeutic efficacy, the compound or the pharmaceutical composition as taught herein can be first administered at different dosing regimes. Typically, levels of the agent in a tissue can be monitored using appropriate screening assays as part of a clinical testing procedure, e.g., to determine the efficacy of a given treatment regimen. The frequency of dosing is within the skills and clinical judgement of medical practitioners (e.g.,doctors, veterinarians or nurses). Typically, the administration regime is established by clinicaltrials which may establish optimal administration parameters. However, the practitioner may vary such administration regimes according to the one or more of the aforementioned factors, e.g., subject’s age, health, weight, sex and medical status. The frequency of dosing can be varied depending on whether the treatment is prophylactic or therapeutic. Toxicity and therapeutic efficacy of the agent as described herein or pharmaceutical compositions comprising the same can be determined by known pharmaceutical proceduresin, for example, cell cultures or experimental animals. These procedures can be used, e.g.,for determining the LD50 (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio LD50 / ED50. Pharmaceutical compositions that exhibit high therapeutic indices are preferred. While pharmaceutical compositions that exhibit toxic side effects can be used, care should be taken to design a delivery system that targets such compounds to the site of affected tissue in order to minimize potential damage to normal cells (e.g., non-target cells) and, thereby, reduce side effects. The data obtained from the cell culture assays and animal studies can be used in formulating a range of dosage for use in appropriate subjects. The dosage of such pharmaceutical compositions lies generally within a range of circulating concentrations that include the ED50 with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilised. For a pharmaceutical composition used as described herein, the therapeutically effective dose can be estimated initially from cell culture assays. A dose can be formulated in animal models to achieve a circulating plasma concentration range that includes the IC50 (i.e., the concentration of the pharmaceutical composition which achieves a half-maximal inhibition of symptoms) as determined in cell culture. Such information can be used to more accurately determine useful doses in humans. Levels in plasma can be measured, for example, by high performance liquid chromatography. In particular embodiment, the compound as taught herein is the main or only active ingredient of the pharmaceutical composition. Examples The following examples are provided for the purpose of illustrating the present invention and by no means should be interpreted to limit the scope of the present invention. 1. Chemical synthesis of representative compounds of the invention Unless otherwise stated, laboratory reagent grade solvents were used. Reagents were obtained from various commercial sources and were used without any prior purification. Characterisation of all compounds was done with1H and13C NMR and mass spectrometry. NMR spectra were recorded with a 400 MHz Bruker Avance III Nanobay spectrometer with Ultrashield. All obtained spectra were analysed using MestReNova analytical chemistry software. Chemical shifts are displayed in ppm and coupling constants are shown in hertz (Hz). ES mass spectra were obtained from an Esquire 3000plus Ion Trap Mass Spectrometer from Bruker Daltonics. The UPLC (ultra performance liquid chromatography), used to quantify the purity of the products, was an ACQUITY UPLC H-Class system with a TUV detector Waters coupled to an MS detector Waters Qda. Waters Acquity UPLC BEH C181.7 μm, 2.1 mm × 50 mm column was used. The eluent was composed of two different solvents. Solvent C consisted of water with 0.1% formic acid, solvent D was acetonitrile. For most of the experiments, unless stated otherwise, the general method was used. The column was first equilibrated for 0.15 min with a mixture of 95% solvent C and 5% solvent D. After that, solvent D was increased linearly to 100% over 1.75 min before being held constant for 0.25 min, followed by a mixture of 95% solvent C and 5% solvent D for 0.75 min (flow rate 0.7 ml / min). All mass spectra were recordedover a m / z range of 100–1000. The wavelength for UV detection was 254 nm. Method II startswith equilibration of column for 0.15 min with a mixture of 95% solvent C and 5% solvent D. After that, solvent D was increased linearly to 100% over 2.50 min before being held constant for 0.75 min, followed by a mixture of 95% solvent C and 5% solvent D for 0.75 min (flow rate 0.7 ml / min).Selected compounds of the invention were analysed by high resolution mass spectrometry:10μL of each sample (concentration = 10–5 M) was injected using the CapLC system (Waters,Manchester, UK) and electrosprayed using a standard electrospray source. Samples were injected with an interval of 5 min. Positive ion mode accurate mass spectra were acquired usinga Q-TOF II instrument (Waters, Man-chester, UK). The MS was calibrated prior to use with a 0.2% H3PO4 solution. The spectra were lock mass corrected using the known mass of the nearest H3PO4 cluster.During the chemical synthesis, flash purification was performed when necessary, on a BiotageISOLERA One flash system equipped with an internal variable dual wavelength diode array detector (200−400 nm). Reverse phase purifications were done using Buchi EcoFlex C18 cartridges, dry sample loading was done by self-packing sample cartridges using Celite® 545. Gradients used varied for each purification. Several synthesis procedures that were used in the preparation of intermediates and final products are summarized here as “General Procedures”. The final products have a purity above 95% unless otherwise stated. Scheme 1.
[0002] Scheme 3. General procedure A: (sulfone)amide coupling (Scheme 1 or 2, step (a))In a round-bottom flask 3-chloro-4-nitrobenzenesulfonyl chloride 1 (1.0 eq) was dissolved inTHF. After cooling down to -40°C a solution containing the appropriate aliphatic amine substituent (1.0 eq) and triethylamine (2.0 eq) in THF was added dropwise. After the addition was complete, the resulting mixture was allowed to warm up to room temperature over the course of 1 hour. Subsequently, the reaction mixture was diluted with EtOAc (20-50 ml) and washed with water (3 x 10-50 mL). The organic layer was dried using anhydrous sodiumsulfate before being concentrated in vacuo. The crude reaction products 2 and 9-10 was usedwithout any further purification for the next step.General procedure B: nucleophilic aromatic substitution (Scheme 1 or 2, step (b))The intermediate 2 and 9-10 were dissolved in ACN (20-75 mL), and N,N-diisopropylethylamine (3.0 eq) and cyclohexylamine (3.0 eq) were added to the reaction mixture. It was then heated to 90°C and stirred overnight. After the consumption of the starting material, the mixture was cooled to room temperature, and the solvent was concentrated under vacuum. It was further diluted with water and EtOAc. The aqueous layer was extractedwith EtOAc (3 × 10-50 mL). The collected organic layers were washed with brine (20 mL), thendried using anhydrous sodium sulfate, and concentrated under vacuum. The residue was either directly used for the subsequent step without purification or purified by reversed-phaseflash column chromatography (water / MeOH) to obtain the intermediate 3 and 11-12.General procedure C: catalytic hydrogenation (Schemes 1 or 2 or 3 step (c))Intermediate 3, 11-12 and 21 (1.0 eq) were dissolved in MeOH and the solution was purgedwith argon. Palladium hydroxide on carbon (20% Pd(OH)2 / C, 50% of water, 0.1 eq) was added under inert atmosphere while continuously stirring. Next, the reaction mixture was put under hydrogen atmosphere and stirred for 12-72 hours at room temperature. After completion ofthe reaction, the solution was filtered through a patch of Celite® and the filtrate wasconcentrated under reduced pressure. The crude compound was purified by reversed-phaseflash chromatography (water / MeOH) to yield products 4, 13-14 and 22.General procedure D: reductive amination (Schemes 1 or 2 or 3 step (d))Compounds 4, 13-14 and 22 (1.0 eq) were dissolved in THF, followed by the addition of aceticacid (23.0 eq.) and the corresponding aldehyde or ketone (1.5 eq). After 15 minutes, sodium cyanoborohydride (2.5 eq) was added and the reaction mixture was stirred at room temperature for 12-16 hours. After completion, the reaction was quenched with water and the product was extracted twice into DCM. The combined organic layers were dried over sodium sulphate, filtered and loaded on Celite®. The crude compounds were purified by reversed-phase flash chromatography (water / MeOH) to yield products 5-6 or 15-16 or 23-25.General procedure E: Boc deprotection (Schemes 1 or 2 or 3 step (e))Compounds 5-6, 15-16, 29-36 or 38-39 (1.0 eq) were dissolved in dichloromethane followedby the addition of a 4 M solution of hydrochloric acid in dioxane (15 eq.) The reaction mixture was stirred at room temperature for 2 hours. After reaction, diethyl ether was added to thereaction mixture to precipitate compounds 7-8 or 17-18 or 41-50.

Biological evaluation of the compounds of the invention Inhibition of ML162-Induced Ferroptosis in HT1080 human fibrosarcoma cells Human fibrosarcoma cells HT1080 cells were obtained from American Type Culture Collection (ATCC). HT1080 cells were cultured in EMEM medium supplemented with 10% FCS and L- glutamine (1 mM), sodium pyruvate and nonessential amino acids. Cell death was measured using Envision multimode plate reader (PE). In order to determine IC50 values, HT1080 were seeded in a 384-well plate at a density of 3500 cells / well in 40µl in an incubator overnight at 37 °C with 5% CO2. The next day, the cells were pretreated for 1h (in triplicates) with a 1 / 3 dilution series of ferrostatin-1 analogues ranging from 1 µM to 0.5 nM and Sytox Green (1.6 μM). All the compound’s stock solutions were prepared in DMSO at 100 mM concentration. After stimulating the cells with ML162 1 μM the plate was transferred to the incubator. SytoxGreen intensity was measured after 8, 12, 16 and 24 h using an excitation filter of 485 nm and an emission filter of 535 nm. Dose-response curves were made as % cell death inhibition, taking ML162 treated samples as 0 % inhibition and Fer-1 (1 µM) + ML-162 samplesas the 100 % inhibition. Cell death percentage was calculated as 100 – (( x – 100%inh) / (0%inh – 100%inh))*100). Curves were plotted in Spotfire software, and IC50 values werecalculated using logistic regression curves. Data is presented in Table 2.Fluorescence-Enabled Inhibited Autoxidation (FENIX)Ref. Shah et al. (2019) Cell Chem. Biol.26, 1594-1607 Unless otherwise stated, laboratory reagent grade solvents were used. Reagents were obtained from various commercial sources and were used without any prior purification. L-α- phosphatidylcholine (Egg, Chicken), powder was purchased from Merck Life Science B.V. DTUN and STY-BODIPY were synthesized according to methods described in Shah et al. (2019) Cell Chem. Biol. 26, 1594-1607. Fluorescence was measured using the UV / vis spectrophotometer Synergy MX, Biotek with Gen5.To quantify radical trapping antioxidant activity in phospholipid bilayers to a clear bottom black-walled 96-well plate for fluorescence-base assays (Invitrogen by Thermo Fisher Scientific) was added 250 µL of a solution containing liposomes (1 mM), styrene-conjugated BODIPY (STY-BODIPY) (1 µM), and the respective radical trapping antioxidant (RTA) (4 µM). The solutions were made in larger volumes in Eppendorfs, pre-mixed and 250 µL aliquot was transferred to each well. The plate was incubated for 10 minutes at 37°C in the BioTekSynergyMx plate reader, followed by a fast-mixing protocol for 5 minutes. The plate wasejected from the plate reader and autoxidation was initiated by the addition of a 50 µL aliquotof (E)-1,2-bis((2-methyldecan-2-yl)oxy)diazene (DTUN) (0.2 mM in EtOH / PBS (3 / 47, v / v),followed by another mixing protocol for 5 minutes. Data were acquired by excitation probes at 488 nm and emission was measured at 518 nm (read intervals 1.0 min). Kinetic readparameters: (i) optic position: bottom, (ii) gain: 80, (iii) bandwidth: 9.0. The results of the FENIXassay are presented in Table 2 as inhibition rate constants (kinh), logkinh and stoichiometries (n) of tested compounds. Kinetic solubility A turbidimetric method was used. First, a series of DMSO compound stock solutions were prepared (0.15-5 mM) from the stock solution of the compound in DMSO (10 mM). An aliquot of 4μL stock solution was added to 196μL PBS buffer (pH 7.4). A series of concentrations were prepared (3.13-200 μM), including a blank on a microtiter plate. The microtiter plate was shaken for 10 seconds and incubated for 2 hours at 37°C. Turbidity was measured using the UV / vis spectrophotometer Synergy MX, Biotek with Gen5. When there was no turbidity measured at a given concentration the sample was assumed to be dissolved. Data is presented in Table 2. Table 2.

Human and mouse microsomal stability Experimental procedure Pooled liver microsomes (Ultrapool Human Liver microsomes or Mouse CD-1 male Liver microsomes), with a protein concentration of 20 mg / ml, were purchased from CorningGentest™ (now Discovery Life Science – Gentest) and stored at -80°C until use. Themicrosomes (final protein concentration 0.5 mg / ml), 0.1 M phosphate buffer pH 7.4 and test compound (final substance concentration 1 µM), were preincubated at 37°C for 10 min before the addition of NADPH Regenerating System (solution A and B from Corning Gentest™, final concentration 1 mM) to initiate the reaction. For each compound tested, a control without the cofactor was included. In this case, 0.1 M phosphate buffer at pH 7.4 was added instead of the NADPH regenerating system. In addition, with each new batch of microsomes, two positive control compounds were incorporated. These controls represented substances with high (verapamil, with human Clint = 178.9 μL / min*mg; diazepam, with mouse Clint = 549 μL / min*mg) and low clearance (dextromethorphan, with human Clint = 34.6 μL / min*mg; diphenhydramine, with mouse Clint = 64.0 μL / min*mg). Each compound was incubated for 45 minutes at 37°C and shaken at 500 rpm. The reactions were stopped by transferring the incubate into acetonitrile, containing an internal standard, inEppendorfs at the appropriate time points in a 1:3 ratio (0, 5, 10, 15, 30, and 45 minutes forcompounds, and 0, 15, and 45 minutes for the negative control of those compounds). Subsequently, the Eppendorfs were centrifuged at 3000 rpm for 20 minutes at 4°C to precipitate the protein. Quantitative AnalysisAfter protein precipitation, the sample supernatant from each time point was analysed usingUPLC-MS / MS. The analysis followed the general UPLC method for microsomal stability described below. The UPLC (ultra-performance liquid chromatography), used to quantify the microsomal stability of the products, was an ACQUITY UPLC H-Class system with a TUV detector Waters (not used in this assay) coupled to an MS / MS detector Xevo Waters TQD. Waters Acquity UPLC BEH C181.7 μm, 2.1 mm × 50 mm column was used. The eluent was composed of two different solvents. Solvent A consisted of water with 0.1% formic acid, solvent B was acetonitrile with 0.1% formic acid. The column was first equilibrated for with a mixture of 95% solvent A and 5% solvent B until the delta of psi decrease below 40 psi. Themethod began with a short equilibration to reach 50% of solvent A and B in 0.15 min. Followingthis, solvent B was increased linearly to 95% over 2.75 min before being held constant for0.70 min (flow rate 0.7 ml / min). The specific masses of the compounds were tracked using tuning files generated via Intellistart®, and quantification was aided by an internal standard. Data processing All obtained readouts were processed using Microsoft Excel. From a plot of ln peak area ratio (compound peak area / internal standard peak area) against time, the gradient of a line is determined by linear regression. Subsequently several parameters were calculated using the equations below: ^Elimination rate constant (k) = ( - gradient)^ Half Time (t1 / 2) = ln (2) / k^ Clint (µL / min / mg of protein) = V x ln (2) x t1 / 2^Where V = (Incubation volume µL) / (Microsomal protein mg / g liver) Data is presented in Table 3.

Following incubation, 200 µL of each of the incubated solutions is removed and filtered using a 96-well 0.4 µM MultiScreen HTS PCF Polycarbonate centrifugal filter plate. The filtrate is serially diluted 1 in 4, 1 in 40 and 1 in 400 fold into 75:25 DMSO:water. The standards and samples are quantified using a Waters Acquity UPLC-MS / MS system.

LogD Shake Flask CPD-017 (0.5 mg) is dissolved in octanol pre-saturated with 0.1 M phosphate buffer (pH 7.4) and sonicated for 30 min.0.1 M phosphate buffer (pH 7.4) pre-saturated with octanol is added to the octanol solution and shaken at 1000 rpm for 30 min at 22 °C. The mixed samples are then centrifuged at 1000 rpm for 5 min at 22 °C. An aliquot of the octanol fraction is removed from each mixture and diluted into DMSO. The remainder of the octanol fraction is removed, and an aliquot of the aqueous fraction is transferred into a fresh tube. The aqueous aliquot is centrifuged again at 1000 rpm for 5 min at 22 °C and an aliquot of the resulting aqueous fraction is diluted into DMSO. The resulting octanol and aqueous fraction solutions are analysed by LC-MS / MS using Cyprotex generic conditions. The relative amount of CPD-017 in the aqueous fraction solution is quantified against a 5 point standard curve, which is produced by serially diluting the octanol fraction solution. LogD is calculated using the following equation:Where: Coct = Concentration in octanol standard (corrected for dilution); Caq = Concentrationin aqueous sample (corrected for dilution).

Plasma Protein Binding Solutions of CPD-017 are prepared in species-specific plasma, or other protein (matrix) as appropriate; and pH adjusted where required (typically pH 7.4 for plasma), at a final test concentration of 5 µM (or as agreed with the client) and 0.5% DMSO concentration. The experiment is performed using a Rapid Equilibrium Dialysis (RED) device with the two compartments separated by a semi-permeable membrane. Buffer (typically 0.1 M phosphatefor plasma) containing 0.5% DMSO is added to one side of the membrane and protein to theother side. The system is incubated for 4 hours at 37°C with agitation (250 rpm) on an orbital shaker. CPD-017 incubations are performed in triplicate. Initial samples are prepared by taking aliquots (triplicates) of the plasma immediately after addition of CPD-017 and precipitating with acetonitrile containing internal standard. In addition to CDP-017, Warfarin is assayed as a marker compound to give an indication of the performance of the assay. Post incubation samples are taken from both sides of the membrane. Seven calibration standards are freshly prepared in the appropriate protein. Samples and standards are precipitated with acetonitrile containing internal standard. All samples and standards are matrix matched by addition of an equivalent volume of either buffer, or protein containing DMSO (0.5%) to relevant samples(i.e., buffer is added to the protein samples and protein is added to the buffer samples), giving a final composition of 1:3 sample to solvent.

Microsomes are stored at 80 °C prior to use. Microsomes (final protein concentration 0.5 mg / mL), 0.1 Mphosphate buffer pH 7.4 and CPD-017 (final substrate concentration 1 µM; final DMSOconcentration 0.25 %) are preincubated at 37 °C prior to the addition of NADPH (final concentration 1 mM) to initiate the reaction. A minus cofactor control incubation is included for each CPD-017 where 0.1 M phosphate buffer pH 7.4 is added instead of NADPH (minus NADPH). Two species-specific positive controls are also incubated alongside CPD-017 for each species. All incubations are performed singularly for CPD-017. CPD-017 is incubated for 0, 5, 15, 30 and 45 min.

Hepatocyte Stability Cryopreserved pooled hepatocytes are purchased from a reputable commercial supplier. A range of species and strains are available upon request. Cryopreserved hepatocytes are stored in liquid nitrogen prior to use. A suspension of cryopreserved hepatocytes (final cell density 0.5 x 106 viable cells / mL in Williams E media supplemented with 2 mM L glutamine and 25 mM HEPES) is pre-incubated at 37 °C prior to the addition of CPD-017 (final substrate concentration 1 µM; final DMSO concentration 0.25%) to initiate the reaction. The final incubation volume is 500 µL. Two positive controls are included with each species. Each CPD- 017 is incubated for 0, 5, 10, 20, 40 and 60 min at 37 °C. The reactions are stopped by transferring incubate into acetonitrile at the appropriate time points, in a 1:3 ratio. The termination plates are centrifuged at 3,000 rpm for 30 min at 4 °C to precipitate the protein. Following protein precipitation, the sample supernatants are combined in cassettes of up to 4 test articles, internal standard is added and samples analysed using Cyprotex generic LC- MS / MS conditions. If the metabolite profiling option is chosen prior to the commencement of the study, samples are set aside for profiling. The time points are changed to exclude the 5 min time point and to include a 120 min time point. The time point at which 30-70% of parenthas degraded, and the 120 min time point can then be investigated at 3 different levels ofmetabolite profiling and / or identification. The level of metabolite profiling chosen depends on amount of knowledge and support required by the client and can include rapid, low-resolution analysis to identify whether metabolites are formed, cross species comparisons with high resolution analysis or detailed fragmentation analysis to understand metabolite derivation. From a plot of ln peak area ratio (compound peak area / internal standard peak area) against time, the gradient of the line is determined. Subsequently, half-life and intrinsic clearance (CLint) are calculated using the equations below: where V = Incubation volume (µL) / Number of cells CLint values falling below the lower limit of assay sensitivity (calculated based on t½>3 x incubation time) are categorised as below the lower limit of quantification (<LOQ). Data is presented in Table 4. MDCK-MDR1 Permeability Assay (Unidirectional or Bidirectional) at Cyprotex Discovery Ltd. (UK). Madin-Darby canine kidney (MDCK) cells are an epithelial cell line of canine kidney origin. These cells can be stably transfected to express active P-glycoprotein (MDCK-MDR1) and are ideal for studying drug efflux. Test compound is added to either the apical or basolateral side of a confluent monolayer of MDCK-MDR1 cells and permeability is measured by monitoring the appearance of the test compound on the opposite side of the monolayer using LCMS / MS. If performing a bidirectional assay, the efflux ratio (ER) is calculated from the ratio of BA and AB permeabilities. The experiment measures the permeability of test compound in the apical to basolateral (AB) and / or basolateral to apical (BA) direction across MDCK-MDR1 cells and determines the efflux ratio (ER), which shows whether the test compound undergoes active efflux. The results are reported as apparent permeability coefficients (Papp) along with mean recovery values, and if relevant, the efflux ratio (ER) for the test compound. Experimental procedure MDCK-MDR1 cells obtained from the NIH (Rockville, MD, USA) are used between passagenumbers 6 - 30. Cells are seeded onto Transwell plates at 3.4 x 105 cells / cm2. The cells arecultured in DMEM and media is changed on day 3. On day 4 or 5, the permeability study is performed. Cell culture and assay incubations are carried out at 37 ºC in an atmosphere of 5 % CO2with a relative humidity of 95 %. On the day of the assay, the monolayers are prepared by rinsing the apical and basolateral compartment with Hanks Balanced Salt Solution (HBSS) at the desired pH warmed to 37 °C. Cells are then incubated with HBSS at the desired pH in both apical and basolateral compartments for 30 minutes to stabilise physiological parameters. The dosing solutions are prepared by diluting the test compound with assay buffer to give the desired final test compound concentration (typically 10 µM). Final DMSO concentration of 1 % v / v. The fluorescent integrity marker lucifer yellow is also included in thedosing solution. Analytical standards are prepared from test compound DMSO dilutions andtransferred to buffer, maintaining a ≤1 % v / v DMSO concentration. Typical assay buffer is composed of supplemented HBSS pH 7.4 but a range of other buffers and pH values can be used. For assessment of AB permeability, HBSS is removed from the apical compartment and replaced with test compound dosing solution. The apical compartment insert is then placed into a companion plate containing fresh buffer (containing ≤1 % v / v DMSO). For assessment of BA permeability, HBSS is removed from the companion plate and replaced with test compound dosing solution. Fresh buffer (containing ≤1 % v / v DMSO) is added to the apical compartment insert, which is then placed into the companion plate. At 60 min the apical compartment inserts and the companion plates are separated and apical and basolateralsamples diluted for analysis. Test compound permeability is assessed in duplicate. Testcompounds of known permeability characteristics are run as controls on each assay plate. Test and control Test compounds are quantified by LC-MS / MS cassette analysis using a 7- point calibration with appropriate dilution of the samples. The express analytical method development procedure is performed using UHPLC on either a Waters XevoTMTQ-MS or a Waters XevoTMTQ-S micro. The procedure is performed in a stepwise manner to assess LC- MS / MS optimization and chromatography. The compound is assessed in clean solution using existing Cyprotex chromatographic methods using a UHPLC C18 column and a gradient consisting of either 10 mM ammonium formate with 0.1 % formic acid in water or 10 mM ammonium acetate in water, with either methanol or acetonitrile.50 nM and 0 µM standards in clean solution are prepared to assess the sensitivity and selectivity of the test article response. The starting concentration (C0) is determined from the dosing solution and the experimental recovery calculated from C0 and both apical and basolateral compartment concentrations. The integrity of the monolayer throughout the experiment is checked by monitoring lucifer yellow permeation using fluorimetric analysis. Data The MDCK-MDR1 assay distinguishes between CNS positive and CNS negative compounds based on their Pappvalues (see https: / / www.cyprotex.com / admepk / in-vitro-permeability-and- drug-transporters / mdr1-mdck-permeability for detailed values). The permeability coefficient (Papp) for each test compound is calculated from the following equation: Where dQ / dt is the rate of permeation of the drug across the cells, C0 is the donor compartment concentration at time zero and A is the area of the cell monolayer. C0is obtained from analysis of the dosing solution. For bi-directional experiments, an efflux ratio (ER) is calculated from mean A-B and B-A data. This is derived from: If the ER is greater than or equal to 2 then this indicates drug efflux is occurring. Two controls are screened alongside the test compounds, typically: antipyrine (high permeability) andprazosin (a P-glycoprotein substrate). Data is presented in Table 4.Mitochondrial Objective: To measure the sensitivity and viability (cellular ATP content) of HepG2 cells grown in medium containing either galactose or glucose, in response to CPD-017. Procedure HepG2 human hepatocellular carcinoma cells (other cell types available on request) are plated on an appropriately sized multi-well plate in suitable media at 37 °C in 5 % CO2 for 24 hr prior to dosing of the cells. CPD-017 is diluted in DMSO or other suitable solvents and serial dilutions are made in 0.5 % DMSO or appropriate solvent in medium supplemented with eithergalactose or glucose. CPD-017 at 8 concentrations in triplicate is then incubated for 24 hr(other time points available on request). Appropriate controls are run alongside the assay. At the end of the incubation period, cellular ATP is measured using CellTiter-Glo® (Promega) Data The vehicle control wells are used to determine significance limits. The minimum effective concentration (MEC) is determined from the lowest concentration whose mean value exceeds the significance level, provided either a clear dose-response relationship is observed, or at least two consecutive concentration points are above the significance level. AC50 values are also determined provided a clear dose-response relationship is observed. If the AC50 in cells grown with glucose containing medium is >3-fold greater than with galactose containingmedium CPD-017 is considered to be a mitochondrial toxicant. Data is presented in Table 4. CardiotoxicityhERG Channel Inhibition - QPatch HTX (IC50 Determination):Objective: To assess the potential of the CPD-017 to inhibit the hERG channel.Procedure The experiments are performed on QPatch HTX system (Sophion Biosciences A / S). The system is primed with appropriate extracellular (NaCl, KCl, CaCl2, MgCl2, D-glucose, HEPES, pH 7.4) and intracellular (KCl, MgCl2, EGTA, MgATP, HEPES, pH 7.2) solutions prior toconducting the study in a 48 well plate (QPlate, Sophion Biosciences A / S). All cellsuspensions, buffers and CPD-017 solutions are at room temperature during the experiment. The cells used are HEK293 cells stably transfected with hERG cDNA. The cells are automatically washed and resuspended before being positioned into each well (recording chamber) of the QPlate. The QPatch system follows the general principles of conventional whole-cell patch-clamping: a high resistance seal is formed between the patch electrode and an individual cell, the membrane across the electrode tip is then ruptured and the whole-cell patch-clamp configuration is established. Once a stable patch has been achieved, recording commences in voltage-clamp mode. The standard voltage profile is as follows: step from -80 mV to –50 mV for 200 ms, +20 mV for 4.8 s, step to -50 mV for 5 s then step to the holding potential of -80 mV. The step from -80 mV to the test command (+20 mV) results in an outward current (i.e. current flows out of the cell) and the step from the test command (+20 mV) to -50 mV results in the tail current (the tail current represents deactivation of the current over time). CPD-017 dilutions are prepared by diluting a DMSO solution (default 10 mM), followed by dilution into extracellular buffer such that the final concentrations tested are 0.1, 1, 10 µM (final DMSO concentration 0.1 %). Perfusion solutions contain 0.05% Pluronic F-68 and are stored at room temperature for the duration of the experiment each day. The voltage protocol is run and recorded continuously during the experiment. Cells are treated with vehicle for 3 min (i.e. 0.1% DMSO) followed by three increasing concentrations of CPD-017 (0.1, 1 and 10 µM). CPD-017 is applied in triplicate at each concentration and tested in at least 2 cells. The standard combined exposure time is 5 min. One vehicle group is run per experiment. In the vehicle group, vehicle (0.1 % DMSO) is dispensed as a test substance, followed by addition of a positive control (E-4031). Data Analysis The average of tail current amplitude values recorded from 4 sequential voltage pulses is used to calculate for each cell the effect of CPD-017 by calculating the residual current (% control) compared with vehicle pre-treatment (0% inhibition). The data are plotted and an IC50value is estimated from the concentration-response relationship, if appropriate.hNav1.5 Sodium Channel Assay Qube APC: After whole cell configuration is achieved, thecells are held at -80mV. Onset and steady state block of peak Nav1.5 current is measured using a pulse pattern consisting of a hyperpolarizing pulse to -120mV for a 200ms duration, depolarization to -15mV amplitude for a 40ms duration, followed by step to 40mV for 200ms and finally a 100ms ramp (1.2 V / s) to a holding potential of -80 mV. Peak current is measured during the step to -15 mV. This paradigm is delivered once every 5s to monitor the current amplitude. The parameters measured were difference between the peak inward current on stepping to -15mV (i.e. peak of the current) and the leak current. All data were filtered for seal quality, seal drop, and current amplitude. The peak current amplitude was calculated before and after compound addition and the amount of block was assessed by dividing the Test compound current amplitude by the Control current amplitude. Control data is the mean Nav1.5 current amplitude collected for three pulses (15 seconds) at the end of the vehicle control application; Test compound data is the mean Nav1.5 current amplitude collected for three pulses (15 seconds) at the end of test concentration application for each concentration.hCav1.2 (L- CiPA Calcium Channel Qube APC: Onset and steady state block ofpeak hCav1.2 current is measured using a pulse pattern, repeated every 15 sec. Cells were held at -80mV for a 50ms before stepping to -90mV for 100ms to measure leak current andthen stepped back to - 80mV for 50ms, depolarization to 0mV amplitude for a 40ms duration,followed by step to 40mV for 200ms and finally a 100ms ramp (1.2 V / s) to a holding potential of -80 mV. Peak current is measured during the step to 0mV. Each concentration is applied for 5 minutes. current amplitude is calculated by measuring the differencebetween the peak inward current on stepping to 0mV or the peak inward current at the ramp (i.e. peak of the current) and the leak current. The calcium current is assessed in vehicle control conditions and at the end of each five (5) minute compound application. hERG Potassium Channel Qube APC: After whole cell configuration is achieved, the cell is held at -80mV. The cell is depolarized to +40mV for 500ms and then to -80mV over a 100ms ramp to elicit the hERG tail current. This paradigm is delivered once every 5s to monitor the current amplitude. The parameters measured were the maximum tail current evoked on stepping to 40mV and ramping back to -80mV from the test pulse. All data were filtered for seal quality, seal drop, and current amplitude. The peak current amplitude was calculated before and after compound addition and the amount of block was assessed by dividing the Test compound current amplitude by the Control current amplitude. Control data is the mean hERG current amplitude collected 15 seconds at the end of the control period; Test compound data is the mean hERG current amplitude collected 15 seconds at the end of each 5 minute test compound application for each concentration. Data is presented in Table 4.Genotoxicity: Micronucleus testObjective: To assess the potential of CPD-017 to exhibit genotoxic effects on a panel of cellhealth parameters (cytostatic nuclei, necrotic or apoptotic events, cell cycle analysis (G1, S, G2 / M phase) and micronucleus formation). Procedure TK6 cells, human lymphoblast cell line (other cell lines are available upon request) are stained with cellular tracking dye prior to seeding on appropriately sized multi-well tissue culture plates in appropriate media at 37 °C in 5 % CO2. Test article is serial diluted in solvent and further dilutions are made in appropriate media to achieve 0.5 % solvent. CPD-017 at 8 concentrations in triplicate is then incubated in the absence (24 hr & 3 hr) and / or presence (3 hr) of phenobarbital / beta-naphthoflavone induced rat liver S9 (depending on customer requirements). For S9 incubations, the cells are washed after 3 hr and incubated for a further 21 hr. Appropriate controls for the conditions requested are run simultaneously. At the end of the incubation period the cells are processed with the appropriate dyes and analysed using an Intellicyt iQue® 3 flow cytometer (Sartorius, UK). Cytostatic and necrotic / late apoptoticevents are excluded from micronucleus analysis to prevent under- and over-calculation ofpercentage micronucleus formation. The assay provides simultaneous measurement of multiple cell health parameters including cytostasis, cellular death, cell cycle analysis and micronucleus formation. Data Analysis For readouts other than cell viability, a statistical approach to data analysis is used. The solvent controls are used to determine the definitions of “normal” for each parameter, then the percentage of cells that are low or high responders are calculated (depending on the biological significance of a particular readout). The solvent control wells are used to determine significance limits for wells that have a greater than expected fraction of low or high responders. The MEC is determined from the lowest concentration whose mean value exceeds the significance level, provided either a clear dose response relationship is observed, or at least two consecutive concentration points are above the significance level. AC50 valuesare also determined provided a clear dose response relationship is observed. Data ispresented in Table 4. Ames Fluctuation test: Objective: To assess the potential of CPD-017 to exhibit genotoxic effects High-throughput assay, being performed in 384-well plates and uses four Salmonella strains, TA98, TA100, TA1535 and TA1537 to detect multiple mutations including frameshift mutations and base-pair substitutions as well as to identify certain mutagenic compounds which are not detected by specific bacterial strains. Metabolic activation is assessed by using rat liver S9fraction to determine if major metabolites generated are potential mutagens. Wells thatdisplayed bacteria growth due to the reversion of the histidine mutation are counted and recorded as positive counts. The significance of the positive counts between the treatment (in the presence of CPD-017) and the control (in the absence of test compound) are calculated using the one-tailed Fisher's exact test. Data is presented in Table 4. Reactive Metabolite Formation (Stable Labelled Glutathione Trapping,)Objective: To assess the potential of a glutathione reactive metabolite formation in human livermicrosomes. Procedure Pooled human liver microsomes (final protein concentration 1 mg / mL), 0.1 M phosphate buffer pH 7.4 with MgCl2 (final concentration 3 mM) and CPD-017 (final substrate concentration 50 µM) is incubated at 37°C prior to the addition of NADPH (final concentration 2 mM) and GSH (final concentration 1 mM, 1:1 unlabelled GSH to 13C2, 15NGSH). A control incubation isincluded for each CPD-017 assessed where 0.1 M phosphate buffer pH 7.4 with MgCl2 (finalconcentration 3 mM) is added instead of NADPH (minus NADPH). CPD-017 is incubated for60 min. The reactions are stopped by the addition of acetonitrile. The incubation plates are centrifuged, and the supernatants are diluted 1:2 with water and then analysed by HR-LCMS.Ticlopidine is screened alongside the CPD-017 as a positive control.Data Analysis Following the assay, samples are analysed by MSe over a range of m / z 50 to 1200, with MSe collision energy ramp of 10-40 V in the high energy function. Potential reactive metabolites are identified by processing samples through UNIFI. Metabolites are identified by searching against a list of expected biotransformations with the addition of GSH or an addition of CysGly (when pyroglutamic acid is lost from glutathione prior to conjugation). Reactive metabolites are reported where an isotopic doublet of +3 amu is observed. The reactive metabolite must have a ratio of at least three to one when compared to a corresponding peak in the control sample (unless proposed biotransformation indicates a non-enzymatic i.e. chemical reaction). A ppm error of less than 5 is desirable; when the response for a metabolite observed is low the ppm error may be greater than 5. Additionally, the following diagnostic losses are reported where observed: • Loss of glycine, C2H5NO2, mass of 75.0320 • Loss of pyroglutamic acid, C5H7O3N, mass of 129.0426 • Loss of reduced CysGly, C5H8N2O3S, mass of 176.0256 • Loss of CysGly, C5H10N2O3S, mass of 178.0412 • Loss of reduced glutathione, C10H15N3O6S, mass of 305.0682 • Loss of glutathione, C10H17N3O6S, mass of 307.0838 All potential reactive metabolites are confirmed by expert review prior to release of data. Data is summarized in Table 4.

Test compound is diluted in DMSO and serial dilutions are made in 0.5 % DMSO in growth media. Test compound at 8 concentrations in triplicate is then incubated for 72 hr (dependent upon customer requirements). Appropriate controls are run alongside the assay. At the end of the incubation period, the cells are loaded with the relevant dyes for the appropriate time for each cell health marker. The plate is then scanned using an automated fluorescent cellular imager, ArrayScan® VTI or XTI (Thermo Scientific Cellomics). The assay provides simultaneous measurement of multiple cell health parameters including cell count, nuclear size, DNA structure, phospholipidosis and steatosis. Data Analysis For readouts other than cell viability, a statistical approach to data analysis is used. The solvent controls are used to determine the definitions of “normal” for each parameter, then the software calculates the percentage of cells that are low or high responders (depending on the biological significance of a particular readout). The solvent control wells are then used to determine significance limits for wells that have a greater than expected fraction of low or high responders. The minimum effective concentration is determined from the lowest concentration whose mean value exceeds the significance level, provided either a clear dose-response relationship is observed, or at least two consecutive concentration points are above the significance level. AC50values are also determined provided a clear dose-response relationship is observed. Data is summarized in Table 4. Cytotoxicity Screening Panel (MMP, MP, Cyto C)Objective: To assess the potential of CPD-017 to exhibit toxic effects on a panel of cell healthparameters (cell loss, nuclear morphology, cell membrane permeability, mitochondrial membrane potential changes, mitochondrial mass, DNA fragmentation and cytochrome C localisation). These targets have been shown to be predictive for compounds causing various forms of toxicity. Procedure HepG2 human hepatocellular carcinoma cells (other cell lines are available upon request) are plated on appropriately sized multi-well plates in suitable media at 37°C in 5 % CO2 for 24 hr prior to dosing of the cells. CPD-017 is diluted in solvent, and serial dilutions are made in 0.5% solvent, in growth media. CPD-017 at 8 concentrations (0.04, 0.1, 0.4, 1, 4, 10, 40, 100 µM)in triplicate is then incubated for 72 hr. Appropriate controls are run alongside the assay. At the end of the incubation period, the cells are loaded with the relevant dye / antibody for the appropriate time for each cell health marker. The plate is then scanned using an automated fluorescent cellular imager. The assay provides simultaneous measurement of multiple cell health parameters: ^Cell count: A decreasing number of cells per well indicates toxicity due to necrosis,apoptosis or a reduction in cellular proliferation. ^Nuclear size: An increase in nuclear area can indicate necrosis or G2 cell cycle arrestand a decrease can indicate apoptosis. ^DNA structure: An increase in DNA structure can indicate chromosomal instability andDNA fragmentation. ^Cell membrane permeability: An increase in cell membrane permeability is a generalindicator of cell death. ^Mitochondrial mass: A decrease in mitochondrial mass indicates loss of totalmitochondria and an increase implies mitochondrial swelling or an adaptive response to cellular energy demands. ^Mitochondrial membrane potential (Δψm): A decrease indicates a loss of mitochondrialmembrane potential and mitochondrial toxicity, as well as a potential role in apoptosis signalling, an increase in mitochondrial membrane potential indicates an adaptive response to cellular energy demands.^ Cytochrome c: An increase in cytochrome c release is one of the hallmarks of theapoptosis cascade. Data analysis For readouts other than cell count, a statistical approach to data analysis is used. The solvent controls are used to determine the definitions of “normal” for each parameter, then the software calculates the percentage of cells that are low or high responders (depending on the biological significance of a particular readout). The solvent control wells are then used to determine significance limits for wells that have a greater than expected fraction of low or high responders. The minimum effective concentration is determined from the lowest concentration whose mean value exceeds the significance level, provided either a clear dose-response relationship is observed, or at least two consecutive concentration points are above the significance level. AC50 values are also determined provided a clear dose-responserelationship is observed. Data is summarized in Table 4.Cytochrome P450 inhibition Objective: To assess the potential inhibition of cytochrome P450 isoforms using isoform- specific probe substrates in the presence of 6 concentrations of CPD-017 Procedure CPD-017 is incubated at 6 concentrations (typically 0.1, 0.25, 1, 2.5, 10, 25 µM) in singlicate at 37°C with pooled human liver microsomes in the presence of NADPH (1 mM) and a probe substrate. After incubation, the reactions are terminated by addition to methanol. The termination plates are centrifuged at 2500 rpm for 30 min at 4 °C and an aliquot of the supernatant is transferred to fresh 96-well plates. Formic acid in deionised water (final concentration 0.1 %) containing a cocktail of deuterated metabolite internal standards is added to the supernatants prior to cassette analysis by LC-MS / MS using Cyprotex generic methods. Data Analysis A decrease in the formation of the metabolite compared to vehicle control is used to calculate an IC50value (CPD-017 concentration which produces 50 % inhibition). Metabolite peak area ratio response as a percentage of vehicle control is plotted against the test article concentration and fitted to a simple inhibitory model using the Levenberg-Marquardt algorithm.

Micewere kept in solid bottom cages (TECNIPLAST S.p A., Italy, Type III polysulphone cage; 425 mm x 266 mm x 180 mm). The animals were kept on 4 cm thick layer of corn cob grit, dust-free bedding (Scobis Due - Mucedola, Italy), with a provision of one paper shelters (LillicoBiotechnology, UK). Animals were kept in the holding room with following environmentalconditions: temperature 22°C ± 2, relative humidity 55% ± 10, 15 - 20 air changes per hour,artificial light cycle of 12 hours light (7:00 to 19:00). Animals had free access to potable water and food (SDS VRF 1 (P), UK). All animals were managed similarly and with due regard for their well-being according to prevailing practices and the experimental plan approved by CARE Zagreb (Committee for Animal Research Ethics). Treatment / Experimental Design Animals were assigned to the groups as in Table 5 below. Table 5.

Serial blood samples (ca. 100uL) were collected followingsuccessful puncture of the lateral tail vein using a needle, into K2EDTA-coated tubes. For terminal sampling, before sacrifice, the mice were anesthetized with a cocktail of ketamine and xylazine administered ip. For each terminal time point, blood samples were collected via jugular vein bleeds; ca 0.4 mL of blood were collected and transferred into K2EDTA-coated tubes. Within 30 minutes after blood collection, samples were centrifuged at 1560 g for 10 min at 4°C and the resulting plasma samples were aliquoted into polypropylene tubes (two aliquots of 20 µL) and stored at -20°C until analysis. Tissue sampling Following terminal blood sampling at 0.5, 4 and 24h, animals were euthanized by exsanguination, Tissues were collected into Precellys® tubes, weighed individually, frozen and stored at –70° until analysis. Bioanalysis Analytical procedure Plasma and tissue concentrations were determined by research qualified LC-MS / MS methods.Samples were analysed on a SCIEX triple quadrupole mass spectrometer operating inTurboIonSpray mode. Blank mouse plasma was used for preparation of blank samples, calibrators and quality control samples (QC samples). Tissue samples were homogenized by the addition of water. An aliquot of homogenate was diluted with blank plasma and quantified against plasma calibration curve. The study samples were assayed by batch with a calibration curve (six calibration standard levels at least) including one level corresponding to the target LLOQ and the target ULOQ. A generic internal standard will be used. Each batch included QC samples in duplicate at three concentration levels (one near the limit of quantification, one in the mid-range and one near the high end of the range). Washing solvent and double blank samples was run to avoid any contamination of a sample by its preceding one. Back-calculated concentration of calibration and QC samples provided the basis of accepting or rejecting the batch. The calibration equation was computed by least-squares regression using the selected model, and the concentration of each calibration sample was calculated. If the back-calculated concentration of a calibration sample does not fall within ±15% of the nominal concentration(±20% at the LLOQ), that sample was discarded, and the equation was recalculated. For the calibration and the batch to be valid, the coefficient of determination (r²) must be higher than 0.98 and at least 75% of calibration samples have to remain included. Moreover, for the lowest and the highest levels, only one replicate out of two may be rejected. To qualify the batch, at least 67% of QCs must be within ±15% of their respective nominal, and ≥ 50% of QCs per level should be ±15% of their nominal value.
