[0039] The present invention encompasses all combinations of the specific embodiments described herein, each of which is described herein. [Modes for carrying out the invention]
[0040] <Description of specific embodiments of the present invention>
[0041] It is understood that the examples and embodiments described herein are merely illustrative of the present invention, and that various modifications or changes may be proposed to the parties based on these examples and embodiments, and that such modifications or changes will fall within the spirit and scope of this application and the appended claims. All publications, patents and patent applications cited herein are incorporated herein by reference in their entirety for all purposes.
[0042] The term "alkyl" refers to a hydrocarbon group selected from linear or branched saturated hydrocarbon groups having 1 to 18 carbon atoms, 1 to 12 carbon atoms, or 1 to 6 carbon atoms. Examples of alkyl groups include methyl, ethyl, 1-propyl or n-propyl ("n-Pr"), 2-propyl or isopropyl ("i-Pr"), 1-butyl or n-butyl ("n-Bu"), 2-methyl-1-propyl or isobutyl ("i-Bu"), 1-methylpropyl or s-butyl ("s-Bu"), and 1,1-dimethylethyl or t-butyl ("t-Bu"). Other examples of alkyl groups include 1-pentyl group, 2-pentyl group, 3-pentyl group, 2-methyl-2-butyl group, 3-methyl-2-butyl group, 3-methyl-1-butyl group, 2-methyl-1-butyl group, 1-hexyl group, 2-hexyl group, 3-hexyl group, 2-methyl-2-pentyl group, 3-methyl-2-pentyl group, 4-methyl-2-pentyl group, 3-methyl-3-pentyl group, 2-methyl-3-pentyl group, 2,3-dimethyl-2-butyl group, and 3,3-dimethyl-2-butyl group.
[0043] Lower alkyl means having 1 to 8 carbon atoms, preferably 1 to 6, more preferably 1 to 4. Lower alkenyl or lower alkynyl means having 2 to 8, 2 to 6, or 2 to 4 carbon atoms.
[0044] The term "alkenyl" refers to a hydrocarbon group selected from linear or branched hydrocarbon groups having 2 to 18 carbon atoms, 2 to 12 carbon atoms, or 2 to 6 carbon atoms, and containing at least one C=C double bond. Examples of alkenyl groups may be selected from ethenyl or vinyl groups, propa-1-enyl group, propa-2-enyl group, 2-methylpropa-1-enyl group, buta-1-enyl group, buta-2-enyl group, buta-3-enyl group, buta-1,3-dienyl group, 2-methylbuta-1,3-diene group, hexa-1-enyl group, hexa-2-enyl group, hexa-3-enyl group, hexa-4-enyl group, and hexa-1,3-dienyl group.
[0045] The term "alkynyl" refers to a hydrocarbon group that contains at least one C≡C triple bond and is selected from straight-chain or branched hydrocarbon groups having 2 to 18 carbon atoms, 2 to 12 carbon atoms, or 2 to 6 carbon atoms. Examples of alkynyl groups include ethynyl, 1-propynyl, 2-propynyl (propargyl), 1-butynyl, 2-butynyl, and 3-butynyl groups.
[0046] The term "cycloalkyl" refers to a hydrocarbon group selected from saturated cyclic hydrocarbon groups and partially unsaturated cyclic hydrocarbon groups, including monocyclic and polycyclic groups (e.g., dicyclic and tricyclic groups). For example, the number of carbon atoms in a cycloalkyl group may be 3-12, 3-8, or 3-6. Alternatively, a cycloalkyl group may be a monocyclic group with 3-12, 3-8, or 3-6 carbon atoms. Examples of monocyclic cycloalkyl groups include cyclopropyl, cyclobutyl, cyclopentyl, 1-cyclopenta-1-enyl, 1-cyclopenta-2-enyl, 1-cyclopenta-3-enyl, cyclohexyl, 1-cyclohexa-1-enyl, 1-cyclohexa-2-enyl, 1-cyclohexa-3-enyl, cyclohexadienyl, cycloheptyl, cyclooctyl, cyclononyl, cyclodecyl, cycloundecyl, and cyclododecyl groups. Examples of bicyclic cycloalkyl groups include groups with 7 to 12 ring atoms arranged as bicyclic groups selected from [4,4], [4,5], [5,5], [5,6], and [6,6] ring systems, as well as groups with 7 to 12 ring atoms arranged as bridging bicyclic groups selected from bicyclo[2.2.1]heptane, bicyclo[2.2.2]octane, and bicyclo[3.2.2]nonane. These rings may be saturated and may have at least one double bond (i.e., partially unsaturated), but are not fully conjugated and are not aromatic rings as defined herein.
[0047] In this specification, the term "aryl" refers to a group selected from five- or six-membered carbocyclic aromatic rings (e.g., phenyl); bicyclic systems (e.g., 7- to 12-membered bicyclic systems) in which at least one ring is carbocyclic aromatic (e.g., bicyclic systems selected from naphthalene, indane, and 1,2,3,4-tetrahydroquinoline); and tricyclic systems (e.g., 10- to 15-membered tricyclic systems) in which at least one ring is carbocyclic aromatic (e.g., fluorene).
[0048] For example, the aryl group is selected from a 5- to 7-membered cycloalkyl ring which may contain at least one heteroatom selected from N, O, and S, or a 5- or 6-membered carbocyclic aromatic ring fused with a heterocycle. When the carbocyclic aromatic ring is fused with a heterocycle, the bond site is on the carbocyclic aromatic ring, and when the carbocyclic aromatic ring is fused with a cycloalkyl group, the bond site may be on the carbocyclic aromatic ring or on the cycloalkyl group. A divalent radical formed from a substituted benzene derivative and having a free valence on the ring atom is called a substituted phenylene radical. In monovalent polycyclic hydrocarbon radicals whose names end in "yl", a divalent radical derived by removing one hydrogen atom from a carbon atom with a free valence is named by adding "idene" to the name of the corresponding monovalent radical. For example, a naphthyl group with two bond sites is called naphthylidene.
[0049] The term "halogen" refers to F, Cl, Br, or I.
[0050] The term "heteroalkyl" refers to an alkyl group that contains at least one heteroatom.
[0051] The term "heteroaryl" refers to a group selected from the following:
[0052] A 5-7 member aromatic monocyclic group comprising 1, 2, 3, or 4 heteroatoms selected from N, O, and S, with the remaining ring atoms being carbon;
[0053] A bicyclic group comprising 1, 2, 3, or 4 heteroatoms selected from N, O, and S, wherein the remaining ring atoms are carbon, and at least one ring is an aromatic ring, and at least one heteroatom is present in the aromatic ring; and,
[0054] A tricyclic group comprising 1, 2, 3, or 4 heteroatoms selected from N, O, and S, wherein the remaining ring atoms are carbon, and at least one ring is an aromatic ring, and at least one heteroatom is present in the aromatic ring.
[0055] For example, a heteroaryl group includes a 5-7 membered heterocyclic aromatic ring fused with a 5-7 membered cycloalkyl ring. In such a fused bicyclic heteroaryl ring system, where only one ring contains at least one heteroatom, the bond site may be located on the heterocyclic aromatic ring or on the cycloalkyl ring.
[0056] In a heteroaryl group, if the total number of S atoms and O atoms exceeds 1, these heteroatoms are not adjacent to each other. In some embodiments, the total number of S atoms and O atoms in a heteroaryl group is 2 or less. In some embodiments, the total number of S atoms and O atoms in an aromatic heterocycle is 1 or less.
[0057] Examples of heteroaryl groups include (numbered with the bond position as position 1) pyridyl (e.g., 2-pyridyl, 3-pyridyl, or 4-pyridyl), synnolinyl, pyrazinyl, 2,4-pyrimidinyl, 3,5-pyrimidinyl, 2,4-imidazolyl, imidazopyridinyl, isoxazolyl, oxazolyl, thiazolyl, isothiazolyl, thiadiazolyl, tetrazolyl, thienyl, triazinyl, benzothienyl, furyl, benzofuryl, benzimidazolyl, indolyl, isoindolyl, indolinyl, phthalazinyl, pyrazinyl, pyridadinyl, pyrrolyl, triazolyl, quinolinyl, isoquinolinyl, pyrazolyl, pyrrolopyridinyl (e.g., 1H-pyrrolo[2,3-b]pyridinyl-5-yl), pyrazolopyridinyl (e.g., 1H-pyrazolo[3,4-b]pyridyl Examples include, but are not limited to, benzo[d]thiazole-6-yl, benzoxazolyl (e.g., benzo[d]thiazole-6-yl), pteridinyl, prinyl, 1-oxa-2,3-diazolyl, 1-oxa-2,4-diazolyl, 1-oxa-2,5-diazolyl, 1-oxa-3,4-diazolyl, 1-thia-2,3-diazolyl, 1-thia-2,4-diazolyl, 1-thia-2,5-diazolyl, 1-thia-3,4-diazolyl, flazanil, benzoflazanil, benzothiophenyl, benzothiazolyl, benzoxazolyl, quinazolinil, quinoxalinil, naphthilidinil, phlopyridinil, benzothiazolyl (e.g., benzo[d]thiazole-6-yl), indazolyl (e.g., 1H-indazol-5-yl), and 5,6,7,8-tetrahydroisoquinoline.
[0058] The terms "heterocyclic," "heterocyclic," or "heterocyclyl" refer to a ring selected from 4- to 12 membered monocyclic, bicyclic, or tricyclic saturated or partially unsaturated rings, containing at least one carbon atom in addition to one, two, three, or four heteroatoms selected from oxygen, sulfur, and nitrogen. Furthermore, "heterocyclic" also refers to a group formed by the condensation of a 5- to 7 membered heterocyclic ring containing at least one heteroatom selected from N, O, and S with a 5-, 6-, and / or 7-membered cycloalkyl ring, carbocyclic aromatic ring, or heterocyclic aromatic ring, where the bond site is on the heterocyclic ring when the heterocyclic ring is condensed with a carbocyclic aromatic ring or heterocyclic aromatic ring, and where the bond site may be on the cycloalkyl ring or on the heterocyclic ring when the heterocyclic ring is condensed with a cycloalkyl ring.
[0059] Furthermore, “heterocycle” also refers to an aliphatic spirocycle containing at least one heteroatom selected from N, O, and S, in which case the bond site is located on the heterocycle. These rings may be saturated or may have at least one double bond (i.e., they may be partially unsaturated). The heterocycle may be substituted with an oxo. The bond site may be on the carbon of the heterocycle or on the heteroatom of the heterocycle. The heterocycle is not a heteroaryl as defined herein.
[0060] Examples of heterocycles include (numbered with bond position as position 1): 1-pyrrolidinyl, 2-pyrrolidinyl, 2,4-imidazolidinyl, 2,3-pyrazolidinyl, 1-piperidinyl, 2-piperidinyl, 3-piperidinyl, 4-piperidinyl, 2,5-piperazinyl, pyranyl, 2-morpholinyl, 3-morpholinyl, oxylanyl, azilidinyl, thyranyl, azetidinyl, oxetanyl , thietanyl, 1,2-dithietanyl, 1,3-dithietanyl, dihydropyridinyl, tetrahydropyridinyl, thiomorpholinyl, thioxanil, piperazinyl, homopiperazinyl, homopiperidinyl, azepanil, oxepanil, thiepanil, 1,4-oxathianil, 1,4-dioxepanil, 1,4-oxathiepanil, 1,4-oxazepanil, 1,4-dithiepanil, 1,4- Thiazepanyl, 1,4-diazepane, 1,4-dithianyl, 1,4-azathianyl, oxazepinyl, diazepinyl, thiazepinyl, dihydrothienyl, dihydropyranyl, dihydrofuranyl, tetrahydrofuranyl, tetrahydrothienyl, tetrahydropyranyl, tetrahydrothiopyranyl, 1-pyrrolinyl, 2-pyrrolinyl, 3-pyrrolinyl, indolinyl, 2H-pyranyl, 4H-pyranyl Examples of substituted heterocycles include, but are not limited to, lanyl, 1,4-dioxanyl, 1,3-dioxolanyl, pyrazolinyl, pyrazolidinyl, dithianyl, dithiolanyl, pyrazolidinyl, imidazolinyl, pyrimidinol, 1,1-dioxo-thiomorpholinyl, 3-azabicyclo[3.1.0]hexanyl, 3-azabicyclo[4.1.0]heptanyl, and azabicyclo[2.2.2]hexanyl.

[0061] In this specification, the term "condensed ring" refers to a polycyclic system (e.g., a bicyclic or tricyclic system) in which two rings share only two ring atoms and one bond. Examples of condensed rings include condensed bicyclic cycloalkyl rings, such as groups in which 7 to 12 ring atoms are arranged as bicyclic groups selected from the aforementioned [4,4], [4,5], [5,5], [5,6], and [6,6] ring systems; condensed bicyclic aryl rings, such as the aforementioned 7 to 12-membered bicyclic aryl ring systems; condensed tricyclic aryl rings, such as the aforementioned 10 to 15-membered tricyclic aryl ring systems; condensed bicyclic heteroaryl rings, such as the aforementioned 8 to 12-membered bicyclic heteroaryl rings; condensed tricyclic heteroaryl rings, such as the aforementioned 11 to 14-membered tricyclic heteroaryl rings; and the aforementioned condensed bicyclic heterocyclyl rings and condensed tricyclic heterocyclyl rings.
[0062] In embodiments, substituents are selected from optionally substituted heteroatoms and optionally substituted, heteroatom-containing, and cyclic C1-C18 hydrocarbyls. In particular, optionally substituted, heteroatom-containing, and cyclic C1-C18 hydrocarbyls are optionally substituted, heteroatom-containing, and cyclic alkyl, alkenyl, or alkynyl, or optionally substituted, heteroatom-containing, and / or substituted heteroatoms are halogens, optionally substituted hydroxyls (alkoxy, aryloxy, etc.), optionally substituted acyls (formyl, alkanoyl, carbamoyl, carboxyl, amide, etc.), optionally substituted aminos (amino, alkylamino, dialkylamino, amide, sulfamidyl, etc.), optionally substituted thiols (mercapto, alkylthiol, arylthiol, etc.), optionally substituted sulfinyl or sulfonyls (alkylsulfinyl, arylsulfinyl, alkylsulfonyl, arylsulfonyl, etc.), nitro, or cyano.

[0068] The compounds of the present invention may have chiral centers and therefore may exist as enantiomers. If the compounds of the present invention have two or more chiral centers, they may also exist as diastereomers. Enantiomers and diastereomers are included in the broader definition of stereoisomers. It is intended that all possible stereoisomers, such as substantially purely divided enantiomers, their racemic mixtures, and mixtures of diastereomers, are included in the present invention. It is also intended that all stereoisomers and / or pharmaceutically acceptable salts of the compounds of the present invention are included in the present invention. Unless otherwise specified herein, a reference to one isomer shall also apply to all possible isomers. If the isomer composition is not specified, it shall include all possible isomers.
[0069] The term "substantially pure" means that the stereoisomer of interest contains no more than 35% by weight, for example, no more than 30% by weight, and further, for example, no more than 25% by weight, and further, for example, no more than 20% by weight, of other stereoisomers. In some embodiments, the term "substantially pure" means that the stereoisomer of interest contains no more than 10% by weight, for example, no more than 5% by weight, and further, for example, no more than 1% by weight, of other stereoisomers.
[0070] Unless otherwise specified herein, when a compound of the present invention has an olefinic double bond, such double bond means that it includes both E and Z geometric isomers.
[0071] Some of the compounds of the present invention may have different hydrogen bond sites, and such compounds are called tautomers. For example, a compound having a carbonyl group (-CH2C(O)-) (keto form) may form a hydroxyl group (-CH=C(OH)-) (enol form) through tautomerism. Where applicable, this includes either the keto form or the enol form individually, and mixtures of the keto form and the enol form.
[0072] It may be advantageous to separate reaction products from each other and / or from the starting materials. The desired products obtained in each step or series of steps are separated and / or purified (hereinafter referred to as "separation") by techniques common in the art until the desired degree of homogeneity is obtained. Typically, such separations include multiphase extraction, crystallization from a single solvent or mixed solvent, distillation, sublimation, or chromatography. Chromatography can include any number of methods, such as reversed-phase chromatography and normal-phase chromatography; size exclusion chromatography; ion exchange chromatography; liquid chromatography and chromatographic apparatus at high, medium, and low pressures; small-volume analytical chromatography; pseudo-moving-bed ("SMB") chromatography, preparative thin-layer chromatography, preparative thick-layer chromatography; and small-volume thin-layer chromatography techniques and flash chromatography techniques. Those skilled in the art will be able to apply the techniques that are most likely to achieve the desired separation.
[0073] A diastereomer mixture can be separated into individual diastereomers based on physicochemical differences by methods known to those skilled in the art, such as chromatography and / or fractional crystallization. Enantiomer mixtures can be converted into diastereomer mixtures by reacting them with a suitable optically active compound (e.g., a chiral auxiliary such as a chiral alcohol or moscherate), separated, and then the enantiomers can be separated by converting each resulting diastereomer back into its corresponding pure enantiomer (e.g., by hydrolysis). Enantiomers can also be separated using a chiral HPLC column.
[0074] A single stereoisomer (e.g., a substantially pure enantiomer) may be obtained by splitting the racemic mixture, for example, by forming a diastereomer using an optically active resolving agent. The racemic mixture of the chiral compounds of the present invention can be separated and isolated by appropriate methods, such as (1) forming an ionic diastereomer salt using the chiral compound and separating it by methods such as fractional crystallization; (2) forming a diastereomer compound using a chiral derivatization reagent, separating the diastereomer and converting it to a pure stereoisomer; and (3) directly separating a substantially pure or enriched stereoisomer under chiral conditions.
[0075] "Pharmacologically acceptable salts" include, for example, inorganic salts selected from hydrochloride, phosphate, diphosphate, hydrobromide, sulfate, sulfinate, nitrate, etc., and, for example, malate, maleate, fumarate, tartrate, succinate, citrate, lactate, methanesulfonate, p-toluenesulfonate, 2-hydroxyethylsulfonate, benzoate, salicylate, stearate, alkanate (such as acetate), HOOC-(CH2) nExamples of pharmaceutically acceptable cations include, but are not limited to, organic acid salts selected from salts with -COOH (where n is selected from 0 to 4). Similarly, examples of pharmaceutically acceptable cations include, but are not limited to, sodium, potassium, calcium, aluminum, lithium, and ammonium.
[0076] Furthermore, if the compound is obtained as an acid addition salt, the free base can be obtained by making the solution of this acid addition salt basic.

These compositions include pharmaceutically acceptable diluents and / or carriers, i.e., diluents or carriers that are physiologically compatible and substantially free of pathogenic impurities. Suitable excipients or carriers and methods for preparing administerable compositions are known or obvious to those skilled in the art and are described in further detail in publications such as Remington's Pharmaceutical Science, Mack Publishing Co, NJ (1991). These compositions may also be in the form of controlled-release or sustained-release compositions known in the art. In many applications, the compounds of the present invention are administered in the morning / daytime with a rest period at night.
[0100] The compounds of the present invention may be used as is, or in the form of pharmaceutically acceptable salts such as hydrochloride, hydrobromide, acetate, sulfate, citrate, carbonate, and trifluoroacetate. If the compounds of the present invention have relatively acidic functional groups, salts can be obtained by adding a desired base in a solvent-free environment or a suitable inert solvent. Examples of pharmaceutically acceptable base-added salts include sodium salts, potassium salts, calcium salts, ammonium salts, organic amino salts, and magnesium salts. If the compounds of the present invention have relatively basic functional groups, salts can be obtained by adding a desired acid in a solvent-free environment or a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include salts derived from inorganic acids such as hydrochloric acid, hydrobromic acid, nitric acid, carbonic acid, bicarbonate, phosphoric acid, monohydrogen phosphate, dihydrogen phosphate, sulfuric acid, bisulfate, hydroiodic acid, and phosphorous acid, as well as salts derived from relatively non-toxic organic acids such as acetic acid, propionic acid, isobutyric acid, maleic acid, malonic acid, benzoic acid, succinic acid, suberic acid, fumaric acid, lactic acid, mandelic acid, phthalic acid, benzenesulfonic acid, p-tolylsulfonic acid, citric acid, tartaric acid, and methanesulfonic acid. This also includes amino acid salts such as arginates, and salts of organic acids such as glucuronic acid or galacturonic acid (see, for example, Berge et al, “Pharmaceutical Salts”, Journal of Pharmaceutical Science, 1977, 66, 1-19).
[0101] A neutral compound may be regenerated by contacting the salt with a base or acid using conventional methods and isolating the parent compound. The parent compound differs from the various salt forms in terms of physical properties such as solubility in polar solvents, but in other respects, the salt is equivalent to the parent compound for the purposes of the present invention.
[0102] The present invention provides compounds in the form of prodrugs in addition to salts. Prodrugs of the compounds described herein are compounds that readily undergo chemical transformation under physiological conditions to provide the compounds of the present invention. Furthermore, prodrugs can be converted to the compounds of the present invention by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be gradually converted to the compounds of the present invention when encapsulated in a transdermal patch reservoir with appropriate enzymes or chemical reagents. In some circumstances, prodrugs are often useful because they are easier to administer than the parent drug. For example, prodrugs may have better bioavailability by oral administration than the parent drug. Also, prodrugs may have improved solubility in pharmacological compositions than the parent drug. Various prodrug derivatives are known in the art, for example, prodrugs utilizing hydrolysis or oxidative activation. Examples of prodrugs include, but are not limited to, the compounds of the present invention that are administered as esters ("prodrugs") and metabolically hydrolyzed to the active carboxylic acid.
[0103] Certain compounds of the present invention may exist in an unsolvated form or in a solvated form, including a hydrated form. In general, the solvated form is equivalent to the unsolvated form and is intended to be within the scope of the present invention. Certain compounds of the present invention may exist in various crystalline forms or in an amorphous form. In general, all physical forms are equivalent for the applications envisioned in the present invention and are intended to be within the scope of the present invention.
[0104] Some of the compounds of the present invention have an asymmetric carbon atom (optical center) or a double bond, and their racemates, diastereomers, geometric isomers, and individual isomers are all intended to fall within the scope of the present invention.
[0105] The compounds of the present invention may contain one or more isotopic atoms such as deuterium in proportions not found in nature, and may contain, for example, -CD3, CD2H, or CDH2 instead of methyl. For example, the compounds of the present invention may contain, for example, tritium ( 3 H), Iodine-125 ( 125 I), carbon-14 ( 14 The compounds may be radioactively labeled with radioactive isotopes such as C). All compounds of the present invention containing isotopes, whether radioactive or non-radioactive, are intended to be included within the scope of the present invention.
[0106] The compounds of the present invention are typically administered in a “therapeutic dose,” that is, an amount of the compound that would induce a biological or medical response in a tissue, system, animal, or human, as desired by the researcher, veterinarian, physician, or other clinician. The term “therapeutic dose” encompasses an amount of the compound sufficient, when administered, to prevent the progression of one or more symptoms of the condition or disorder being treated, or to alleviate these symptoms to some extent. The therapeutic dose varies depending on the compound, the disease and its severity, and the age and weight of the mammal being treated.
[0107] The aforementioned contact is typically achieved by administering an effective amount of one or more compounds having general formula I (see above) to the target, and encompasses the various embodiments described above. Generally, the administration is adjusted to a therapeutic dose of about 0.1 to 50 mg / kg, preferably 0.5 to 10 mg / kg, more preferably 1 to 10 mg / kg, but the optimal dose is compound-specific and is generally determined empirically for each compound.
[0108] The term "unit dosage form" refers to a physically divided unit appropriate as a unit dose for human subjects and other mammals, each unit comprising a predetermined amount of the active substance calculated to produce the desired therapeutic effect, along with appropriate pharmaceutical excipients. Typical unit dosage forms include ampoules or syringes filled with pre-measured liquid compositions, or, in the case of solid compositions, pills, tablets, capsules, lozenges, etc. In such compositions, the mimetic is usually included as a trace component (about 0.1 to about 50% by weight, or preferably about 1 to about 40% by weight), with the remainder consisting of processing aids to facilitate the formation of the desired dosage form and various solvents or carriers. Unit dosage form formulations are preferably about 5 mg, about 10 mg, about 25 mg, about 50 mg, about 100 mg, about 250 mg, about 500 mg, or about 1,000 mg per unit. In one particular embodiment, the unit dosage form is packaged in a multi-pack suitable for continuous use, for example, in a blister pack containing a sheet with at least 6, 9, or 12 unit dosage forms.
[0109] The compositions of the present invention may be formulated with and / or co-administered with different compounds to treat applicable indications, to inhibit ferroptotic activity, or to modulate or inhibit diseases associated with ferroptotic dysregulation, such as neuropathy, ischemia-reperfusion injury, acute renal failure, and cancer.
