  • DNA promoter methylation is associated with suppression of gene expression.
  • blockbuster VidazaTM Another class of modifications involve histones which form the protein scaffold that DNA is normally associated with (coiled around) in eukaryotic cells. Histones play a crucial role in organizing DNA and the regulated coiling and uncoiling of DNA around the histones is critical in controlling gene expression - coiled DNA is typically not accessible for gene transcription.
  • histone acetylation histone lysine methylation
  • histone arginine methylation histone ubiquinylation
  • histone sumoylation many of which modify accessibility to the associated DNA by the cells transcriptional machinery.
  • histone marks serve to recruit various protein complexes involved in transcription and repression.
  • An increasing number of studies are painting an intricate picture of how various combinations of histone marks control gene expression in cell-type specific manner and a new term has been coined to capture this concept: the histone code.
  • Histone acetyl transferase and histone deacetylases are the catalytic machines involved in modulation of this histone mark although typically these enzymes are parts of multiprotein complexes containing other proteins involved in reading and modifying histone marks.
  • the components of these protein complexes are typically cell-type specific and typically comprise transcriptional regulators, repressors, co-repressors, receptors associated with gene expression modulation (e.g., estrogen or androgen receptor).
  • Histone deacetylase inhibitors alter the histone acetylation profile of chromatin.
  • histone deacetylase inhibitors like Vorinostat (SAHA), Trichostatin A (TSA), and many others have been shown to alter gene expression in various in vitro and in vivo animal models.

Description

(HETERO)ARYL CYCLOPROPYLAMINE COMPOUNDS AS LSD1 INHIBITORS
The invention relates to (hetero)aryl cyclopropylamine compounds, particularly compounds of formula I, la, la-1 , lb and lc, more particularly compounds of formula I and la, as described and defined herein, and their use in therapy, including e.g., in the treatment or prevention of cancer, a neurological disease, or a viral infection.
Aberrant gene expression in affected tissue as compared to norma! tissue is a common characteristic of many human diseases. This is true for cancer and many neurological diseases which are characterized by changes in gene expression patterns. Gene expression patterns are controlled at multiple levels in the cell. Control of gene expression can occur through modifications of DNA: DNA promoter methylation is associated with suppression of gene expression. Several inhibitors of DNA methylation are approved for clinical use including the blockbuster Vidaza™. Another class of modifications involve histones which form the protein scaffold that DNA is normally associated with (coiled around) in eukaryotic cells. Histones play a crucial role in organizing DNA and the regulated coiling and uncoiling of DNA around the histones is critical in controlling gene expression - coiled DNA is typically not accessible for gene transcription. A number of histone modifications have been discovered including histone acetylation, histone lysine methylation, histone arginine methylation, histone ubiquinylation, and histone sumoylation, many of which modify accessibility to the associated DNA by the cells transcriptional machinery. These histone marks serve to recruit various protein complexes involved in transcription and repression. An increasing number of studies are painting an intricate picture of how various combinations of histone marks control gene expression in cell-type specific manner and a new term has been coined to capture this concept: the histone code.
The prototypical histone mark is histone acetylation. Histone acetyl transferase and histone deacetylases are the catalytic machines involved in modulation of this histone mark although typically these enzymes are parts of multiprotein complexes containing other proteins involved in reading and modifying histone marks. The components of these protein complexes are typically cell-type specific and typically comprise transcriptional regulators, repressors, co-repressors, receptors associated with gene expression modulation (e.g., estrogen or androgen receptor). Histone deacetylase inhibitors alter the histone acetylation profile of chromatin. Accordingly, histone deacetylase inhibitors like Vorinostat (SAHA), Trichostatin A (TSA), and many others have been shown to alter gene expression in various in vitro and in vivo animal models. Clinically, histone deacetylase inhibitors have demonstrated activity in the cancer setting and are being investigated for oncology indications as well as for neurological conditions and other diseases. Another modification that is involved in regulating gene expression is histone methylation including lysine and arginine methylation. The methylation status of histone lysines has recently been shown to be important in dynamically regulating gene expression. A group of enzymes known as histone lysine methyl transferases and histone lysine demethylases are involved in histone lysine modifications. One particular human histone lysine demethylase enzyme called Lysine Specific Demethylase-1 (LSD1) was recently discovered (Shi et al. (2004) Cell 119:941) to be involved in this crucial histone modification. LSD1 has a fair degree of structural similarity, and amino acid identity/homology to polyamine oxidases and monoamine oxidases, all of which (i.e., MAO-A, AO-B and LSD1 ) are flavin dependent amine oxidases which catalyze the oxidation of nitrogen-hydrogen bonds and/or nitrogen carbon bonds. LSD1 has been recognized as an interesting target for the development of new drugs to treat cancer, neurological diseases and other conditions.
Cyclopropylamine containing compounds are known to inhibit a number of medically important targets Including amine oxidases like Monoamine Oxidase A (MAO-A; or MAOA), Monoamine Oxidase B (MAO-B; or MAOB), and Lysine Specific Demethylase-1 (LSD1 ). Tranylcypromine (also known as 2-phenylcyclopropylamine). which is the active ingredient of Parnate® and one of the best known examples of a cyclopropylamine, is known to inhibit all of these enzymes. Since MAO-A inhibition may cause undesired side effects, it would be desirable to identify cyclopropylamine derivatives that exhibit potent LSD1 inhibitory activity while being devoid of or having substantially reduced MAO-A inhibitory activity.
In view of the lack of adequate treatments for conditions such as cancer and neurodegeneration, there is a desperate need for disease modifying drugs and drugs that work by inhibiting novel targets. There is thus a need for the development of LSD1 inhibitors, particularly those which selectively inhibit LSD1.

When substituted and unless otherwise specified, the substituents of an "optionally substituted" group may include, without limitation, one or more substituents independently selected from the following groups or a particular designated set of groups, alone or in combination: lower alkyl, lower alkenyl, lower alkynyl, lower alkanoyl, lower heteroalkyl, lower heterocycloalkyl, lower haloalkyl, lower cycloalkyl, phenyl, aryl, heteroaryl, pyridyl, aryloxy, lower alkoxy, lower haloalkoxy, oxo, lower acyloxy, carbonyl, carboxyl, lower alkylcarbonyl, lower carboxyester, lower carboxamido, cyano, halogen, hydroxyl, amino, amido, nitro, thiol, lower alkylthio, lower haloalkylthio, lower perhaloalkylthio, arylthio, sulfonate, sulfonic acid, trisubstituted silyl, N3, SH, SCH3, C(0)CH3, CO2CH3, CO2H, carbamate, and urea. Two substituents may be joined together to form a fused five-, six-, or seven-membered carbocyclic or heterocyclic ring consisting of zero to three heteroatoms, for example forming methylenedioxy or ethylenedioxy. An optionally substituted group may be unsubstituted (e.g., -CH2CH3), fully substituted (e.g., -CF2CF3), monosubstituted {e.g., -CH2CH2F) or substituted at a level anywhere in-between fully substituted and monosubstituted (e.g., -CH2CF3). Where substituents are recited without qualification as to substitution, both substituted and unsubstituted forms are encompassed. Where a substituent is qualified as "substituted," the substituted form is specifically intended. Additionally, different sets of optional substituents to a particular moiety may be defined as needed; in these cases, the optional substitution will be as defined, often immediately following the phrase, "optionally substituted with." In one specific definition, the optional substituents are chosen from hydroxyl, halo, alkyl, alkoxy, haloalkyl, haloalkoxy, -N(Ci.3 aikyl)2, -NH(Ci-3 alkyl), -NHC(=0)(Ci-3 alkyl), -C(=0)OH,

alkyl), -CHF2, -OCF3, -OCHF2, -SCF3, -CF3, -CN, -NH2, -N02, or tetrazolyl. As used herein, the term "optional substituent" denotes that the corresponding substituent may be present or may be absent. Accordingly, a compound having 1 , 2 or 3 optional substituents may be unsubstituted or may be substituted with i , 2 or 3 substituents.
As used herein, the term "treating a disease" refers to a slowing of or a reversal of the progress of the disease. Treating a disease includes treating a symptom and/or reducing the symptoms of the disease.
As used herein, the term "preventing a disease" refers to a slowing of the disease or of the onset of the disease or the symptoms thereof. Preventing a disease or disorder can include stopping the onset of the disease or symptoms thereof. As used herein, the term "dosage unit" refers to a physically discrete unit, such as a capsule or tablet suitable as a unitary dosage for a human patient. Each unit contains a predetermined quantity of a compound of Formula I which was discovered or believed to produce the desired pharmacokinetic profile which yields the desired therapeutic effect. The dosage unit is composed of a compound of Formula I in association with at least one pharmaceutically acceptable carrier, salt, excipient, or combination thereof.
As used herein, the term "subject" or "patient" or "individual", such as the subject in need of treatment or prevention, may be a eukaryote, an animal, a vertebrate animal, a mammal, a rodent (e.g., a guinea pig, a hamster, a rat, a mouse), a murine (e.g., a mouse), a canine (e.g., a dog), a feline (e.g., a cat), an equine (e.g. a horse), a primate, a simian (e.g., a monkey or ape), a monkey (e.g., a marmoset, a baboon), an ape (e.g., gorilla, chimpanzee, orangutang, gibbon), or a human. The meaning of the terms "eukaryote", "animal", "mammal", efc. is well known in the art and can, for example, be deduced from Wehner und Gehring (1995; Thieme Verlag). In the context of this invention, it is particularly envisaged that animals are to be treated which are economically, agronomically or scientifically important. Scientifically important organisms include, but are not limited to, mice, rats, and rabbits. Lower organisms such as, e.g., fruit flies like Drosophila melagonaster and nematodes like Caenorhabditis elegans may also be used in scientific approaches. Non-limiting examples of agronomicaiiy important animais are sheep, cattie and pig, while, for example, cats and dogs may be considered as economically important animals. Preferably, the subject/patient/individual is a mammal; more preferably, the subject/patient/individual is a human or a non-human mammal (such as, e.g., a guinea pig, a hamster, a rat, a mouse, a rabbit, a dog, a cat, a horse, a monkey, an ape, a marmoset, a baboon, a gorilla, a chimpanzee, an orangutang, a gibbon, a sheep, cattle, or a pig); even more preferably, the subject/patient/individual is a human.
As used herein, the term "dose" or "dosage" refers to the amount of active ingredient that an individual takes or is administered at one time. For example, a 40 mg dose of a compound of Formula I refers to, in the case of a twice-daily dosage regimen, a situation where the individual takes 40 mg of a compound of Formula I twice a day, e.g., 40 mg in the morning and 40 mg in the evening. The 40 mg of a compound of Formula I dose can be divided into two or more dosage units, e.g., two 20 mg dosage units of a compound of Formula I in tablet form or two 20 mg dosage units of a compound of Formula I in capsule form.
As used herein, the term "therapeutically effective amount", such as the therapeutically effective amount of a compound of the present invention, refers to the amount sufficient to produce a desired biological effect (e.g., a therapeutic effect) in a subject. Accordingly, a therapeutically effective amount of a compound may be an amount which is sufficient to treat or prevent a disease or disorder, and/or delay the onset or progression of a disease or disorder, and/or alleviate one or more symptoms of the disease or disorder, when administered to a subject suffering from or susceptible to that disease or disorder. As used herein, a "pharmaceutically acceptable prodrug" is a compound that may be converted under physiological conditions or by solvolysis to the specified compound or to a pharmaceutically acceptable salt of such compound.
As used herein, a "pharmaceutically acceptable salt" is intended to mean a salt that retains the biological effectiveness of the free acids and bases of the specified compound and that is not biologically or otherwise undesirable. A compound for use in the invention may possess a sufficiently acidic, a sufficiently basic, or both functional groups, and accordingly react with any of a number of inorganic or organic bases, and inorganic and organic acids, to form a pharmaceutically acceptable salt. Exemplary pharmaceutically acceptable salts include those salts prepared by reaction of the compounds of the present invention with a mineral or organic acid, such as hydrochlorides, hydrobromides, sulfates, pyrosulfates, bisulfates, sulfites, bisulfites, phosphates, monohydrophosphates, dihydrophosphates, metaphosphates, pyrophosphates, chlorides, bromides, iodides, nitrates, acetates, propionates, decanoates, caprylates, acrylates, formates, isobutyrates, caproates, heptanoates, propiolates, oxalates, malonates, succinates, suberates, sebacates. fumarates, maleates, butyne- 1 ,4 dioates, hexyne-l,6-dioates, benzoates, chlorobenzoates, methylbenzoates, dinitrobenzoates, hydroxybenzoates, methoxybenzoates, phthalates. sulfonates, xyienesulfonates, phenyiacetates, phenylpropionates, phenylbuty rates, citrates, lactates, gamma-hydroxybutyrates, glycollates, tartrates, methane-sulfonates, ethane-sulfonates, propanesulfonates, benzenesulfonates, toluenesulfonates, tnfluoromethansuifonates, naphtnalene-1 -sulfonates, naphthalene-2-sulfonates, mandelates, pyruvates, stearates, ascorbates, or salicylates. When the compounds of the invention carry an acidic moiety, suitable pharmaceutically acceptable salts thereof may include alkali metal salts, e.g. sodium or potassium salts; alkaline earth metal salts, e.g. calcium or magnesium salts; and salts formed with suitable organic ligands such as ammonia, alkylamines, hydroxyalkylamines, lysine, arginine, N-methylglucamine, procaine and the like. Pharmaceutically acceptable salts are well known in the art.
As used herein, a "pharmaceutically acceptable carrier or "pharmaceutically acceptable excipient" refers to a non-API (API refers to Active Pharmaceutical Ingredient) substances such as disintegrators, binders, fillers, and lubricants used in formulating pharmaceutical products. They are generally safe for administering to humans according to established governmental standards, including those promulgated by the United States Food and Drug Administration and the European Medical Agency. Pharmaceutically acceptable carriers or excipients are well known to those skilled in the art.
As is understood by the skilled artisan, certain variables in the list of substituents are repetitive (different name for the same substituent), generic to other terms in the list, and/or partially overlap in content with other terms. In the compounds of the invention, the skilled artisan recognizes that substituents may be attached to the remainder of the molecule via a number of positions and the preferred positions are as illustrated in the Examples.
The compounds of the invention are unexpectedly potent and selective inhibitors of LSD1. Avoiding inhibition of "off-targets" can avoid unwanted or undesirable side-effects like the cheese effect associated with MAO-A. The compounds of the invention are thus useful for the treatment or prevention of any disease or disorder associated with LSD1. This includes cancer, neurological diseases and viral infections, among others.

Accordingly, in one embodiment, the compounds of the invention are used for the treatment or prevention of cancer, particularly for the treatment of cancer, wherein said cancer is chosen from blood cancer, leukemia, lymphoma, breast cancer, lung cancer, prostate cancer, colorectal cancer, brain cancer, neuroblastoma, bladder cancer, liver cancer, sarcoma, myeloma and skin cancer. In another embodiment, the compounds of the invention are used for the treatment or prevention (particularly for the treatment) of blood cancers (also known as hematological cancers), including leukemias (for example, acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML), chronic neutrophilic leukemia, chronic eosinophilic leukemia, chronic lymphocytic leukemia (CLL), acute lymphoblastic leukemia (ALL), or hairy cell leukemia), lymphomas and myelomas, prostate cancer, breast cancer, lung cancer, colorectal cancer, brain cancer or skin cancer. In a preferred embodiment, the compounds of formula I, including compounds of formula la, la-1 , lb and Ic, are used for the treatment of a blood cancer. More preferably, the compounds of formula I, including compounds of formula la, la-1 , lb and Ic, are used for the treatment of leukemia, including acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML), chronic neutrophilic leukemia, chronic eosinophilic leukemia, chronic lymphocytic leukemia (CLL), acute lymphoblastic leukemia (ALL), and hairy cell leukemia. Typically, compounds according to Formula I, la, la-1 , lb or lc can be effective at an amount of from about 0.01 pg/kg to about 100 mg/kg per day based on total body weight. The active ingredient may be administered at once, or may be divided into a number of smaller doses to be administered at predetermined intervals of time. The suitable dosage unit for each administration can be, e.g., from about 1 g to about 2000 mg, preferably from about 5 pg to about 1000 mg. Even more preferably, the amount of active ingredient administered is from about 5 pg to about 100 mg per day. These doses will depend on the pharmacokinetic parameters of the particular compound and other ADME properties as well as the efficacy of the compound in a particular disease setting. It should be understood that the dosage ranges set forth above are exemplary only and are not intended to limit the scope of this invention. The therapeutically effective amount for each active compound can vary with factors including but not limited to the activity of the compound used, stability of the active compound in the patient's body, the severity of the conditions to be alleviated, the total weight of the patient treated, the route of administration, the ease of absorption, distribution, and excretion of the active compound by the body, the age and sensitivity of the patient to be treated, and the like, as will be apparent to a skilled artisan. The amount of administration can be adjusted as the various factors change over time.
While it is possible that a compound of the invention may be administered for use in therapy directly as such, it is typically administered in the form of a pharmaceutical composition, which comprises said compound as active pharmaceutical ingredient together with one or more pharmaceutically acceptable excipients or carriers.
The compounds of the invention may be administered by any means that accomplish their intended purpose. Examples include administration by the oral, parenteral, intravenous, subcutaneous or topical routes. For oral delivery, the active compounds can be incorporated into a formulation that includes pharmaceutically acceptable carriers such as binders (e.g., gelatin, cellulose, gum tragacanth), excipients (e.g., starch, lactose), lubricants (e.g., magnesium stearate, silicon dioxide), disintegrating agents (e.g., alginate, Primogel, and corn starch), and sweetening or flavoring agents (e.g., glucose, sucrose, saccharin, methyl salicylate, and peppermint). The formulation can be orally delivered in the form of enclosed gelatin capsules or compressed tablets. Capsules and tablets can be prepared in any conventional techniques. The capsules and tablets can also be coated with various coatings known in the art to modify the flavors, tastes, colors, and shapes of the capsules and tablets. In addition, liquid carriers such as fatty oil can also be included in capsules.
Suitable oral formulations can also be in the form of suspension, syrup, chewing gum, wafer, elixir, and the like. If desired, conventional agents for modifying flavors, tastes, colors, and shapes of the special forms can also be included. In addition, for convenient administration by enteral feeding tube in patients unable to swallow, the active compounds can be dissolved in an acceptable lipophilic vegetable oil vehicle such as olive oil, corn oil and safflower oil.
The active compounds can also be administered parenterally in the form of solution or suspension, or in lyophilized form capable of conversion into a solution or suspension form before use. In such formulations, diluents or pharmaceutically acceptable carriers such as sterile water and physiological saline buffer can be used. Other conventional solvents, pH buffers, stabilizers, anti-bacteria agents, surfactants, and antioxidants can all be included. For example, useful components include sodium chloride, acetates, citrates or phosphates buffers, glycerin, dextrose, fixed oils, methyl parabens, polyethylene glycol, propylene glycol, sodium bisulfate, benzyl alcohol, ascorbic acid, and the like. The parenteral formulations can be stored in any conventional containers such as vials and ampoules.
Routes of topical administration include nasal, bucal, mucosal, rectal, or vaginal applications. For topical administration, the active compounds can be formulated into lotions, creams, ointments, gels, powders, pastes, sprays, suspensions, drops and aerosols. Thus, one or more thickening agents, humectants, and stabilizing agents can be included in the formulations. Examples of such agents include, but are not limited to, polyethylene glycol, sorbitol, xanthan gum, petrolatum, beeswax, or mineral oil, lanolin, squaiene, and the like. A special form of topical administration is delivery by a transdermal patch. Methods for preparing transdermal patches are disclosed, e.g., in Brown, et a!. (1988) Ann. Rev. Med. 39:221-229 which is incorporated herein by reference.
Subcutaneous implantation for sustained release of the active compounds may also be a suitable route of administration. This entails surgical procedures for implanting an active compound in any suitable formulation into a subcutaneous space, e.g., beneath the anterior abdominal wall. See, e.g., Wilson ef a/. (1984) J. Clin. Psych. 45:242-247. Hydrogels can be used as a carrier for the sustained release of the active compounds. Hydrogels are generally known in the art. They are typically made by crosslinking high molecular weight biocompatible polymers into a network, which swells in water to form a gel like material. Preferably, hydrogels are biodegradable or biosorbabie. For purposes of this invention, hydrogels made of polyethylene glycols, collagen, or poly(glycolic-co-L-lactic acid) may be useful. See, e.g., Phillips ef a/. (1984) J. Pharmaceut. Sci., 73: 1718-1720.
The active compounds can also be conjugated, to a water soluble non- immunogenic non-peptidic high molecular weight polymer to form a polymer conjugate. For example, an active compound is covalently linked to polyethylene glycol to form a conjugate. Typically, such a conjugate exhibits improved solubility, stability, and reduced toxicity and immunogenicity. Thus, when administered to a patient, the active compound in the conjugate can have a longer half-life in the body, and exhibit better efficacy. See generally, Burnham (1994) Am. J, Hosp, Pharm. 15:210-218. PEGylated proteins are currently being used in protein replacement therapies and for other therapeutic uses. For example, PEGylated interferon (PEG-INTRON A®) is clinically used for treating Hepatitis B. PEGylated adenosine deaminase (ADAGEN®) is being used to treat severe combined immunodeficiency disease (SCIDS). PEGylated L-asparaginase (ONCAPSPAR®) is being used to treat acute lymphoblastic leukemia (ALL). It is preferred that the covalent linkage between the polymer and the active compound and/or the polymer itself is hydrolytically degradable under physiological conditions. Such conjugates known as "prodrugs" can readily release the active compound inside the body. Controlled release of an active compound can also be achieved by incorporating the active ingredient into microcapsules, nanocapsules, or hydrogels generally known in the art. Other pharmaceutically acceptable prodrugs of the compounds of this invention include, but are not limited to, esters, carbonates, thiocarbonates, N-acyl derivatives, N-acyloxyalkyl derivatives, quaternary derivatives of tertiary amines, N-Mannich bases, Schiff bases, amino acid conjugates, phosphate esters, metal salts and sulfonate esters.
Liposomes can also be used as carriers for the active compounds of the present invention. Liposomes are micelles made of various lipids such as cholesterol, phospholipids, fatty acids, and derivatives thereof. Various modified lipids can also be used. Liposomes can reduce the toxicity of the active compounds, and increase their stability. Methods for prepanng liposomal suspensions containing active ingredients therein are generally known in the art. See, e.g., U.S. Patent No. 4,522,81 1 ; Prescott, Ed., Methods in Cell Biology, Volume XIV, Academic Press, New York. N. Y. (1976).
The active compounds can also be administered in combination with another active agent that synergistically treats or prevents the same symptoms or is effective for another disease or symptom in the patient treated so long as the other active agent does not interfere with or adversely affect the effects of the active compounds of this invention. Such other active agents include but are not limited to anti-inflammatory agents, antiviral agents, antibiotics, antifungal agents, antithrombotic agents, cardiovascular drugs, cholesterol lowering agents, anticancer drugs, hypertension drugs, and the like.
Combination therapy includes administration of a single pharmaceutical dosage formulation which contains a compound of the invention and one or more additional active agents, as well as administration of the compound of the invention and each additional active agent in its own separate pharmaceutical dosage formulation. If administered separately, the administration can be simultaneous, sequential or separate, and the compound of the invention and the additional therapeutic agent(s) can be administered via the same administration route or using different administration routes, for example one compound can be administered orally and the other intravenously. In particular, when a compound of formula I, la, la-1 , lb or lc is used for the treatment or prevention of cancer, said compound can be administered in combination with one or more further agents known to be useful in the treatment or prevention of cancer, including chemotherapy or radiotherapy. Typically, for combination therapy with a compound of the invention any antineoplastic agent that has activity versus a cancer being treated or prevented with a compound of the invention may be used. Examples of antineoplastic agents that can be used in combination with the compounds and methods of the present invention include, in general, and as appropriate, alkylating agents, anti-metabolites, epidophyllotoxins, antineoplastic enzymes, topoisomerase inhibitors, procarbazines, mitoxantrones, platinum coordination complexes, biological response modifiers and growth inhibitors, hormonal/anti-hormonal therapeutic agents and haematopoietic growth factors. Exemplary classes of antineoplastic agents include the anthracyclines, vinca drugs, mitomycins, bleomycins, cytotoxic nucleosides, epothilones, discodermolides, pteridines, diynenes and podophyllotoxins. Particularly useful members of those classes include, for example, carminomycin, daunorubicin, aminopterin, methotrexate, methopterin, dichioromethotrexate, mitomycin C, porfiromycin, 5- fluorouracil, 6-mercaptopurine, gemcitabine, cytosine arabinoside, podophyllotoxin or podo-phyllotoxin derivatives such as etoposide, etoposide phosphate or teniposide, melphalan, vinblastine, vincristine, leurosidine, vindesine, ieurosine, paclitaxel and the like.

General Synthetic Route Description
ZU
Compounds of Formula I can be synthesized in accordance with or in analogy to the general routes described below. Unless otherwise stated, in the methods described below the meanings of the different substituents in each synthetic intermediate and in each compound of formula I are the meanings described above with regard to a compound of formula I. Other routes known by the ordinary skilled artisan, as well as other reactants and
25 intermediates, can also be used to arrive at the compounds of Formula I. The reaction schemes described below are only meant to represent examples of the invention and are in no way meant to be a limit of the invention. In some of the processes described below it may be necessary or advisable to protect reactive or labile groups with conventional protecting groups. Both the nature of these protecting groups and the procedures for their introduction and removal are well known in the art (see for example Greene TW and Wuts
30 PGM "Greene's Protecting Groups in Organic Synthesis", 4th edition, Wiley, 2006). Whenever a protecting group is present, a subsequent deprotection step will be required, which can be performed under standard conditions well known in the art, such as those described in the above reference.
In general, the compounds of formula I can be prepared by reductive alkylation of a cyclopropylamino derivative 35 of formula II with a ketone of formula III, as shown below in Scheme 1 :
Figure imgf000118_0001
SCHEME 1
Wherein A, B, D, Rw, R , Ry, Rz have the meaning disclosed above in relation to a compound of formula I.
Said reductive alkylation can be performed under standard conditions for reductive alkylations, well known in the art. For example, a suitable set of conditions is reacting II with III using a reducing agent such as a borohydride (e.g., sodium triacetoxyborohydride or sodium borohydride) in a suitable solvent such as dichioroethane or methanol, optionally in the presence of an acid such as acetic acid. In order to conduct the reaction, it is necessary that any other amino group that may be present either in II or in III be protected using conventional amino-protecting groups to avoid any side reactions; a subsequent deprotection step will be required then if such amino protecting group is present, in order to obtain a compound of formula I. Any suitable amino-protecting group may be used, such as for example a tert-butoxycarbonyi (Boc) group. If Boc is used, deprotection can be carried out under standard conditions, for example under acidic conditions using HCI in an organic solvent such as diethyl ether or 1 ,4-dioxane, or trifluoroacetic acid (TFA) in dichloromethane. When HCI is used in the last step of the synthesis, compounds of formula I are obtained as a hydrochloride salt. Likewise, if TFA is used, the compounds will be obtained as a trifluoroacetate.
The cyclopropylamino derivatives of formula II and the ketones of formula III are commercially available or can be prepared following methods disclosed in the literature.
More detailed methods to obtain compounds of formula I are described below.
The compounds of Formula I wherein Rw, Rx, Ry, R2 = H can be synthesized, for example, by the general route described in Scheme 2. This route is particularly suitable for compounds wherein B = H or R1 since the corresponding aldehyde (1 ) is either commercially available or can be readily obtained.

SCHEME 2: DCE (Dichloroethane), DMSO (Dimethyl sulfoxide), THF (Tetrahydrofuran). aq = aqueous. Aldehydes of Formula (1) are subjected to a Homer-Wadsworth-Emmons reaction using triethyl phosphono acetate and a base preferably potassium tert-butoxide in a suitable solvent such as tetrahydrofuran to get the ethyl acrylate derivatives of formula (2) which are then subjected to cyclopropanation reaction using trimethylsulfoxonium iodide and sodium hydride in dimethyl sulfoxide as a solvent leading to (trans)-ethyl cyclopropanecarboxylate derivatives of formula (3) (obtained as a trans ((1 S, 2R) and (1 R, 2S)) racemic mixture). Hydrolysis to the corresponding (trans)-cyclopropanecarboxylic acid derivatives of formula (4) can be performed under basic conditions using for example NaOH in a suitable solvent such as MeOH. The subsequent reaction of compound (4), first with ethyl chloroformate and triethylamine in acetone and later with sodium azide in water leads to the formation of (trans)-cyclopropanecarbonyl azide derivatives of formula (5). Reaction with tert-butanol results in the formation of tert-butyl (trans)- cyclopropylcarbamate derivatives of formula (6). Deprotection of the Boc-group in acidic conditions, for example using HCI 2M in diethyl ether in a suitable solvent such as diethyl ether or using HCI in 1 ,4-dioxane, leads to the formation of the (trans)- cyclopropanamine derivatives of formula (7). Alternatively, the ( trans') -cyclopropanamine derivatives of formula (7) can be synthesized by reaction of aldehydes of formula (1) with nitromethane and ammonium acetate using tetrahydrofuran as a solvent, leading to the formation of nitrostyrene of formula (10). Later cyclopropanation reaction using trimetiisulfoxonium iodide and potassium tert-butoxide results in the formation of trans nitrocyclopropyl derivatives of formula (11) (obtained as a trans ((1 S, 2R), (1 R, 2S)) racemic mixture) and final reduction using zinc in hydrochloric acid affords the (trans)-cyclopropanamine derivatives of formula (7).
Reductive alkylation of the derivatives of formula (7) with ketones of formula (8) under standard conditions, for example using sodium triacetoxyborohydride or sodium borohydride as reducing agent in a suitable solvent such as dichloroethane or methanol leads to the formation of (trans)-cyclopropylamino derivatives of formula (9), which corresponds to a compound of formula I, and particularly la, wherein Rw, Rx, R>, Rz = H. In case the ketones of formula (8) contain a protected amino group, for example a Boc-protected amine (Boc:ierf- butoxycarbonyl), an additional deprotection reaction step will be required to render a compound (9), which can be performed in acidic conditions, for example using HCI 2M in diethyl ether in a suitable solvent such as diethyl ether, or using HCI in 1 ,4-dioxane.

These are subjected to a Horner-Wadsworth-Emmons reaction under the same conditions disclosed in Scheme 2 to get the ethyl acrylate derivatives of formula (14) which are then subjected to cyclopropanation reaction under the same conditions disclosed in Scheme 2 to give the (trans)-ethyl cyclopropanecarboxylate derivatives of formula (15). Following the same conditions disclosed for the conversion of a compound (3) to a compound (7) in scheme 2, a compound (15) is converted into the (trans)-cyclopropanamine derivative of formula (19). Alternatively, the (trans)-cyclopropanamine derivatives of formula (19) can be synthesized from aldehydes of formula (13) by conversion into a nitrostyrene (21), subsequent cyclopropanation to give a compound (22) and reduction of the nitro group under the same conditions disclosed in scheme 2 for the conversion of a compound (1) into a compound (7) via compounds (10) and (11). Reductive alkylation of the derivatives of formula (19) with ketones of formula (8) under the conditions disclosed in scheme 1 or 2 yields a compound (20), which corresponds to a compound of formula I wherein B = -L-E and Rw, Rx, R>, R∑ = H and L = -(CH2)x-0-. in case the ketone of formula (8) contains a protected amino group, for example a Boc-protected amine (Boc: tert-butoxycarbonyl), an additional deprotection reaction step will be required to render a compound (20), which can be performed in acidic conditions, for example using HCI 2M in diethyl ether in a suitable solvent such as diethyl ether, or using H(J in 1 ,4-dioxane.

When the ketones of formula (8) contain a protected amino group, for example a Boc-protected amine (Boc: tert- butoxycarbonyl), an additional deprotection reaction step will be required to render a compound (49). The deprotection can be performed in acidic conditions, for example using HCI 1 ,4-dioxane in a suitable solvent such as 1 ,4-dioxane or HCI in Et20 using Et20 as solvent.
Alternatively, (trans)-cyciopropylamlno derivatives of formula (49) can be synthesized by removal of the Boc- group of tert-butyl (trans)-cyclopropylcarbamate derivatives of formula (6) in acidic conditions, for example using HCI in a suitable solvent such as 1 ,4-dioxane, resulting in the (trans)-cyclopropanamine derivatives of formula (7). Reductive alkylation of compounds (7) with ketones of formula (8) under the same conditions as disclosed in Scheme 1 or 2, for example using sodium triacetoxyborohydride or sodium borohydride as reducing agent In a suitable solvent such as dichloroethane or methanol, leads to the formation of (trans)- cyclopropylamino derivatives of formula (9). Reaction of (9) with di-f-butyl dicarbonate under basic conditions using for example triethylamine in a suitable solvent such tetrahydrofuran leads to the Boc-protected derivatives of formula (27). These are converted into the (trans)-cyclopropanamine derivatives of formula (50) by reaction with commercially available boronic acid or ester derivatives of formula (46) using a suitable solvent such as acetonitrile and water, a base, such as for example potassium carbonate and a palladium catalyst such as Tetrakis(triphenylphospine) Palladium (0). Removal of the Boc-group in acidic conditions, for example using HCI in 1 ,4-dioxane in a suitable solvent such as 1 ,4-dioxane or HCI in EtzO using EbO as solvent, leads to the formation of the (trans)-cyclopropanamine derivatives of formula (49).
Aldehydes of formula (1), boronic acid or ester derivatives of formula (46) and ketones of formula (8) are commercially available or can be prepared using well known synthetic procedures starting from readily available starting materials.
Furthermore, some compounds of the invention can be obtained from other compounds of formula I by appropriate interconversion reactions of functional groups present in a compound of formula I in one or several steps, using well known reactions in organic synthesis under standard experimental conditions. Said transformations can be carried out upon R1, R2 or R3 and include, for example, the substitution of a primary or secondary amine or of an alcohol by treatment with an alkylating agent, the reduction of a nitro group to an amine, the conversion of an amine into an amide, sulfonamide, sulfamide, carbamate or urea, the palladium- catalyzed cross-coupling of amines with aryl halides, etc. Such interconversion reactions can be performed upon a compound of formula I as well as upon any suitable synthetic intermediate described in the above Schemes. The salts of a compound of formula I can be obtained during the final isolation and purification of the compounds of the invention or can be prepared by treating a compound of formula I with a sufficient amount of the desired acid (or base) to give the salt in a conventional manner.
In the above schemes 2 to 5 and 8 the cyclopropanation reaction under the conditions disclosed always leads to a racemic mixture of the trans-isomers of compounds (3), (11), (15) and (22). If the synthetic procedures are continued using the trans racemic mixture thus obtained, the corresponding compounds of formula I are obtained as mixtures of trans-isomers. Likewise, In schemes 6 and 7 the cyclopropanation reaction under the conditions disclosed leads to a mixture of cis/trans isomers of compounds (34) and (40). If the synthetic procedure is continued using said isomer mixture, the corresponding compounds of formula I are obtained as mixtures of cis/trans isomers. As used herein, cis and trans refers to the disposition of groups -A-B versus - NH-D on the cyclopropyl ring. Where the processes for the preparation of the compounds of the invention give rise to mixtures of stereoisomers, individual stereoisomers of a compound of formula I can be obtained by separation from a compound of formula I obtained as a mixture of stereoisomers, using well known methods such as formation of diastereomeric pairs by salt formation with an optically active acid followed by fractional crystallization and regeneration of the free base, or by chiral preparative chromatography. Alternatively, it is possible to obtain optically pure or enantiomerically enriched synthetic intermediates, which can then be used as such in subsequent steps, at various stages of the synthetic procedures described above, using any known method for chiral resolution. Preferably, the chiral separation is performed upon trans-cyclopropylamines of formula (7), (19), (25), (37) or (48). Separation can also be performed at other stages of the procedure, for example upon a compound of formula (34) or (40). A suitable method to obtain the enantiomers of the trans cyclopropylamines (7), (19), (25), (37) and (48) comprises contacting a trans-substituted cyclopropylamine with a chiral recrystallization agent in a solvent (particularly under conditions that are sufficient for the crystallization of the salt of the chirai recrystallization agent and the trans substituted cyclopropylamine); and isolating the crystallized salt of the chiral recrystallization agent and the trans substituted cyclopropylamine, thereby preparing an enantiomer of a trans N-substituted cyclopropylamine. A suitable chiral recrystallization agent is S (+) mandelic acid, D (-) tartaric acid, L (+) tartaric acid, L (-) di-p-toluoyl tartaric acid, or R (-) mandelic acid. Suitable solvents are tetrahydrofuran, ethanol or mixtures thereof with H2O.
Alternatively, it is possible for a person skilled in the art to obtain optically pure or enantiomerically enriched final compounds (or synthetic intermediates) by using chiral chromatography. Examples

Biological Assays
Example 109: Biological Assays - Inhibition of LSD1
The compounds of the invention can be tested for their ability to inhibit LSD1. The ability of the compounds of the invention to inhibit LSD1 can be tested as follows. Human recombinant LSD1 protein was purchased from BPS Bioscience Inc (catalog reference number 50100: human recombinant LSD1 , GenBank accession no. NM_015013, amino acids 158-end with N-terminal GST tag, MW: 103 kDa). In order to monitor LSD1 enzymatic activity and/or its inhibition rate by our inhibitor(s) of interest, di-methylated H3-K4 peptide (Anaspec) was chosen as a substrate. The demethylase activity was estimated, under aerobic conditions, by measuring the release of H2O2 produced dunng the catalytic process, using the Amplex® Red hydrogen peroxide/peroxidase assay kit (Invitrogen).
Briefly, a fixed amount of LSD1 was incubated on ice for 15 minutes, in the absence and/or in the presence of at least eight 3-fold serial dilutions of the respective inhibitor (e.g., from 0 to 75 μΜ, depending on the inhibitor strength). Tranylcypromine (Biomol International) was used as a control for inhibition. Within the experiment, each concentration of inhibitor was tested in duplicate. After leaving the enzyme interacting with the inhibitor, KM of di-methylated H3-K4 peptide was added to each reaction and the experiment was left for 30 minutes at 37°C in the dark. The enzymatic reactions were set up in a 50 mM sodium phosphate, pH 7.4 buffer. At the end of the incubation, Amplex® Red reagent and horseradish peroxidase (HPR) solution were added to the reaction according to the recommendations provided by the supplier (Invitrogen), and left to incubate for 5 extra minutes at room temperature in the dark. A 1 μΜ H2O2 solution was used as a control of the kit efficiency. The conversion of the Amplex® Red reagent to resorufin due to the presence of H2O2 in the assay, was monitored by fluorescence (excitation at 540 nm, emission at 590 nm) using a microplate reader (Infinite 200, Tecan). Arbitrary units were used to measure level of H2O2 produced in the absence and/or in the presence of inhibitor.
The maximum demethylase activity of LSD1 was obtained in the absence of inhibitor and corrected for background fluorescence in the absence of LSD1. The IC50 value of each inhibitor was calculated with ι αμι irciu ni¾iii ουϊιννσΓΘ.
The results presented in Table 1 below show the results of the LSD1 inhibition studies for a number of the Example compounds. In Table 2 the IC50 values for all examples tested in this assay are shown. Parnate (tranylcypromine; i.e., 2-trans phenylcyclopropy!amine) was found to have a IC50 value of 35±10 micromolar. The studies show that the compounds of the invention have unexpectedly potent LSD1 inhibition.
Example 110: Biological Assays ■ Monoamine Oxidase Assays for determining the selectivity of the compounds of the invention for LSD1
Human recombinant monoamine oxidase proteins MAO-A and MAO-B were purchased from Sigma Aldrich. MAOs catalyze the oxidative deamination of primary, secondary and tertiary amines. In order to monitor MAO enzymatic activities and/or their inhibition rate by inhibitor(s) of interest, a fluorescence-based (inhibitor- screening assay was set up. 3-(2-Aminophenyl)-3-oxopropanamine (kynuramine dihydrobromide, Sigma Aldrich), a non fluorescent compound was chosen as a substrate. Kynuramine is a non-specific substrate for both MAO-A and MAO-B activities. While undergoing oxidative deamination by MAO activities, kynuramine is converted into 4-hydroxyquinoline (4-HQ), a resulting fluorescent product.
The monoamine oxidase activity was estimated by measuring the conversion of kynuramine into 4- hydroxyquinoline. Assays were conducted in 96-well black plates with clear bottom (Corning) in a final volume of 100 μΙ_. The assay buffer was 100 mM HEPES, pH 7.5. Each experiment was performed in duplicate within the same experiment.
Briefly, a fixed amount of MAO (0.25 Mg for MAO-A and 0.5 pg for MAO-B) was incubated on ice for 15 minutes in the reaction buffer, in the absence and/or in the presence of at least eight 3-fold serial dilutions each. Clorgyline and Deprenyl (Sigma Aldrich) was used as a control for specific inhibition of MAO-A and MAO-B respectively. After leaving the enzyme(s) interacting with the inhibitor, M of kynuramine was added to each reaction for MAO-B and MAO-A assay respectively, and the reaction was left for 1 hour at 37°C in the dark. The oxidative deamination of the substrate was stopped by adding 50 μΙ_ of NaOH 2N. The conversion of kynuramine to 4- hydroxyquinoline, was monitored by fluorescence (excitation at 320 nm, emission at 360 nm) using a microplate reader (Infinite 200, Tecan). Arbitrary units were used to measure levels of fluorescence produced in the absence and/or in the presence of inhibitor.
The maximum of oxidative deamination activity was obtained by measuring the amount of 4-hydroxyquinoline formed from kynuramine deamination In the absence of inhibitor and corrected for background fluorescence in the absence of MAO enzymes. The IC50 values of each inhibitor were calculated with GraphPad Prism Software.
The results obtained with compounds of the invention in the biological assays of examples 109 and 110 are shown below.

In addition, the compounds exhibit high selectivity versus MAO-A and MAO-B, with IC50 values for LSD1 in general ≥ 100-fold more potent than the corresponding IC50 values for MAO-A and MAO-B..
Example 111 : Cellular assay - Induction of differentiation of THP-1 leukemia cells
Acute Myeloid Leukemia (AML) is characterized by the presence of leukemic cells with a maturation arrest that divide rapidly. With the induction of terminal differentiation, AML cells lose the ability to proliferate and end up dying without the need of a direct cytotoxic effect.
By analyzing the induction of CD 1 b membrane expression on THP-1 cells we are assessing the ability of LSD1 inhibitors to induce terminal monocytic differentiation of a MLL-AF9 AML cell line. The assay was performed as follows:
THP-1 cells were established from the penpheral blood of a 1 -year-old boy with acute monocytic ieukemia at relapse in 1978. They carry t(9;11)(p21 ;q23) leading to MLL-MLLT3 (MLL-AF9) fusion gene. This cell line can undergo monocytic differentiation upon treatment with the appropriate stimulus. THP-1 were purchased from DSMZ GmbH (Deutsche Sammlung von Mikroorganismen und Zellkulturen) and cultured in RPMI 1640 medium containing 10% of fetal bovine serum.
In this assay, 150, 000 THP-1 cells were seeded in 1 ml of complete culture medium in 6-well tissue culture plates. Serial dilutions of the compounds were prepared in DMSO and then further diluted in complete medium to generate solutions of concentrations that are double of the final concentration at which the cells will be exposed. 1 ml of these 2x concentrated solutions was added to the cells. DMSO final content must be the same in all the wells and must be kept below 0.1% v/v (usually 0.01-0.02% v/v), since higher DMSO content can induce differentiation of THP-1 cells.
Cells were kept in the presence of test compound for 96h at a 5% CO2 atmosphere at 37°C. After this treatment period, cells were harvested, washed twice with PBS buffer and placed in a V-bottom 96-well plate. Each treated sample was split in two. One was stained with a phycoerythrin-labeled anti-CD11 b antibody (clone ICRF44, purchased from eBiosciences) and the other with the relevant phycoerythrin-labeled isotype control antibody (mouse IgGi, purchased from eBiosciences). Samples were incubated in the dark at 4°C for 30-60 minutes and washed three times in PBS buffer containing 1% fetal bovine serum.
Samples were analyzed in a flow cytometer equipped with a blue laser (488nm). Emitted fluorescence was detected and quantified with a 575/30nm filter. Percentage of CD11 b positive cells, as an indicator of monocytic differentiation, was determined compared to isotype control antibody stained cells. EC50 values were calculated by non-linear regression analysis.
The results obtained with compounds of the Invention in this test are shown in Table 3 below.

57 2.0 These results show that compounds of the invention exhibit very potent activity in inducing differentiation of leukemia THP-1 cells, which indicates that these compounds are particularly useful for the treatment or prevention of leukemias. Previous reports of LSD1 have found that it is involved in cell proliferation and growth. Some studies have implicated LSD1 as a therapeutic target for cancer. Huang ef al. (2007) PNAS 104:8023-8028 found that polyamine inhibitors of LSD1 modestly cause the reexpression of genes aberrantly silenced in cancer cells and particularly colorectal cancer (Huang et al. Clin Cancer Res. (2009) Dec 1 ;15(23):7217-28. Epub 2009 Nov 24. PMID: 19934284). Scoumanne et al, ((2007) J. Biol, Chem. May 25:282(21): 15471 -5) found that deficiency in LSD1 leads to a partial cell cycle arrest in G2/M and sensitizes cells to growth suppression induced by DNA damage. Kahl et al. ((2006) Cancer Res. 66(23):11341-7.) found that LSD1 expression is correlated with prostate cancer aggressiveness. Metzger ef al. ((2005) Nature, 437 (7057), 436-439) reported that LSD1 modulation by siRNA and pargyline regulates androgen receptor (AR) and may have therapeutic potential in cancers where AR plays a role, like prostate, testis, and brain cancers. Lee ef al. ((2006) Chem. Biol. 13:563- 567) reported that tranylcypromine derepresses Egr-1 gene expression in some cancer lines. A body of evidence is accumulating that Egr-1 is a tumor suppressor gene in many contexts (see e.g., Calogero ef al. (2004) Cancer Ceil international 4:1 exogenous expression of EGR-1 resulted in growth arrest and eventual cell death in primary cancer cell lines; Lucerna ef al. (2006) Cancer Research 66 (13), 6708-6713 show that sustained expression of Egr-1 causes antiangiogeneic effects and inhibits tumor growth in some models; Ferraro ef al. ((2005) J. Clin. Oncol. Mar 20;23(9):1921-6) reported that Egr-1 is downregulated in lung cancer patients with a higher risk of recurrence and may be more resistant to therapy. Thus, increasing Egr-1 expression via inhibition of LSD1 is a therapeutic approach for some cancers. Recent studies have also implicated LSD1 in brain cancer (Schulte et al. (2009) Cancer Res. Mar 1 ;69(5):2065-71). Other studies have implicated LSD1 in breast cancer (Lim et al. Carcinogenesis, (2010), 31(3): 512-20, Epub 2009 Dec 30. [Epub ahead of print] PMID: 20042638), lung, bladder and colorectal cancers (Hayami ef al (2011 ), Int J Cancer, 128(3): 574-86, PMID:20333681) and leukemia (Binda et al (2010), J Am Chem Soc, 132(19): 6827-33, PMID:20415477).
Thus, a body of evidence has implicated LSD1 in a number of cancers, which suggests that LSD1 is a therapeutic target for cancer. The instant inventors have discovered a class of LSD1 inhibitors that can be used to treat diseases where LSD1 is implicated as a therapeutic target like cancer. Accordingly, the (hetero)aryl cyclopropylamine compounds of the invention can be used to treat such diseases.
Recent studies have also implicated LSD1 in viral infection and reactivation. In particular it was shown that pharmacological inhibitors of LSD1 like parnate and siRNA knock down of LSD1 caused reduced viral infectivity and reduced reactivation after latency (Liang ef al. (2009) Nat. Med. 15(11):1312-1317). Therefore it is believed that the compounds of the invention can be used for treating or preventing viral infection. Furthermore, it is believed that the compounds of the invention can treat or prevent viral reactivation after latency. Thus, without being bound by theory, the inventors have identified a new class of cyclopropanamine-based LSD1 inhibitors with unexpected potency and selectivity for LSD1 , a biologically relevant target in oncology and other diseases.
