## Background
This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/917,189, filed May 10, 2007, which is hereby incorporated by reference in its entirety.


FIELD OF THE INVENTION
The present invention relates to compounds, compositions, methods for the treatment of various neurological and psychological disorders, and the use of the compounds in combination therapy. In particular, the present invention relates to such compounds, compositions, and methods, where the compounds are novel aryl- and heteroaryl-substituted tetrahydrobenzo-1,4-diazepine derivatives.
BACKGROUND OF THE INVENTION
It is well known that the neurotransmitters, dopamine (DA), norepinephrine (NE), and serotonin (5-HT), regulate a number of biological processes and that decreased levels of DA, NE, and 5-HT are associated with a number of neurological disorders and their physical manifestations. Significant effort has been expended on devising methods for adjusting the levels of these neurotransmitters in order to produce a desired pharmacological effect. Preventing the reuptake of these neurotransmitters in any combination of one, two, or all three of them is likely to be effective in treating these disorders. Targeting the dopamine transporter (DAT), norepinephrine transporter (NET), and the serotonin transporter (SERT) proteins has proven to be an effective way of increasing the levels of the respective monoamines.
Methylphenidate, currently used for the treatment of attention deficit-hyperactivity disorder, is known to be selective for inhibition of the DAT. Also, U.S. Pat. No. 5,444,070 discloses selective inhibitors of the dopamine reuptake as treatments for Parkinson's disease, drug addiction or abuse including cocaine and amphetamines.
Selective norepinephrine reuptake inhibitors (NARI) have also been disclosed. U.S. Pat. No. 6,352,986 describes methods of treating attention deficit-hyperactivity disorder (ADHD), addictive disorders, and psychoactive substance use disorders with Reboxetine. Also, Atomoxetine (STRATTERA®) is currently marketed as a selective NET reuptake inhibitor for ADHD.
The use of selective serotonin reuptake inhibitors (SSRI) has been shown to be effective in treating depressive disorders. Sertraline, Citalopram, and Paroxetine are well known examples of SSRIs used to treat disorders, such as depression, obsessive compulsive disorder, and panic attacks. There are several known difficulties with the SSRI class of therapeutics, including the slow onset of action, unwanted side effects, and the existence of a significant subset of the population that is not responsive to SSRI therapy.
Selective inhibitors of DAT, NET, and SERT reuptake may also be co-administered with each other or with other drugs. U.S. Pat. No. 5,532,244 discloses the use of serotonin reuptake inhibitors in combination with a serotonin 1A antagonist for the treatment of obsessive-compulsive disorder, depression, and obesity. The use of a serotonin or norepinephrine reuptake inhibitor in combination with a neurokinin-1 receptor antagonist has been disclosed in U.S. Pat. No. 6,121,261 for the treatment of ADHD. U.S. Pat. No. 4,843,071 discloses the use of a norepinephrine reuptake inhibitor in combination with a norepinephrine precursor in the treatment of obesity, drug abuse, or narcolepsy. U.S. Pat. No. 6,596,741 discloses the use of a NE, DA, or 5-HT inhibitor with either a neurokinin-1 receptor antagonist or a serotonin-1D antagonist for the treatment of a wide variety of conditions.
Also advantageous is the use of compounds that inhibit one or more of the neurotransmitters at the same time. The antidepressant qualities of the dual NET and SERT reuptake inhibitor duloxetine is disclosed in European Patent No. EP 273658. Venlafaxine is disclosed in U.S. Pat. No. 4,535,186 as a reuptake inhibitor of both NE and 5-HT for the treatment of depressive disorders. U.S. Pat. No. 6,635,675 discloses the use of the dual NE and 5-HT reuptake inhibitor milnacipran for the treatment of chronic fatigue syndrome and fibromyalgia syndrome. In addition, dual NE and 5-HT reuptake inhibitors are also disclosed in U.S. Pat. No. 6,136,083 for the treatment of depression. It is also recognized that compounds which inhibit the reuptake of NE, DA, and 5-HT in varying ratios not specifically mentioned here would also be advantageous.
Treating illnesses by inhibiting the reuptake of all three of the monoamines either through combination therapy or “triple inhibitors” may have clinical benefit as well. Rationale for inclusion of a dopamine enhancing component in anti-depressant therapy includes observed deficits in dopaminergic function, the success of combination therapy with dopamine agonists and traditional antidepressants, and an increased sensitivity in dopamine receptors due to chronic anti-depressant administration (Skolnick et al., Life Sciences, 73:3175-3179 (2003)). Combination therapy with an SSRI and a noradrenaline and dopamine reuptake inhibitor was shown to be more efficacious in patients with treatment-resistant depression (Lam et al, J. Clin. Psychiatry, 65(3):337-340 (2004)). Another study using a combination of a serotonin and norepinephrine reuptake inhibitor with a norepinephrine and dopamine reuptake inhibitor reported a significant decrease in depressive symptoms in patients with refractory major depressive disorder who had failed to respond previously to either agent alone (Papkostas, G. I., Depression and Anxiety, 23:178-181 (2006)). In addition, the combination of bupropion-SR with either SSRIs or norepinephrine and dopamine reuptake inhibitors was found to induce less sexual dysfunction than monotherapy (Kennedy et al, J. Clin. Psychiatry, 63(3):181-186 (2002)). As such, inhibitory activity against DA reuptake, in addition to NE and 5-HT reuptake, is expected to provide a more rapid onset of anti-depressant effect than other mixed inhibitors which are selective for NET and SERT over DAT. PCT International Publication Nos. WO 03/101453 and WO 97/30997 disclose a class of compounds which are active against all three monoamine transporters. Also, PCT International Publication No. WO 03/049736 discloses a series of 4-substituted piperidines, each of which displays similar activity against DA, NE, and 5-HT transporters. Bicyclo[2.2.1]heptanes (Axford et al., Bioorg. Med. Chem. Lett., 13:3277-3280 (2003)) and azabicyclo[3.1.0]hexanes (Skolnick et al., Eur. J. Pharm., 461:99-104 (2003)) are also described as triple inhibitors of the three monoamine transporters.
Lehman et al., Archiv der Pharmazie, 317(7):595-606 (1984) describes compounds of formula (1) as products of cyclization and reduction of 2-[chloroacetyl(phenyl)amino]benzoates. No biological activity of these compounds was reported in the above-mentioned reference.

Misiti et al., Journal of Heterocyclic Chemistry, 8:231-236 (1971) describes the compound of formula (2) as a product of the Schmidt reaction on 1,2,3,4-tetrahydroquinolin-4-ones, followed by reduction. The compound was prepared in order to clarify structural details. No biological activity of this compound was reported in the above-mentioned reference.




There is still a large need for compounds that block the reuptake of norepinephrine, dopamine, and serotonin and treat various neurological and psychological disorders.
The present invention is directed to achieving this objective.

Results of recent clinical investigations with drugs, such as duloxetine, venlafaxine, atomoxetine, and others that work mechanistically through transporter reuptake inhibition provide evidence that potency and selectivity are important factors in leading to drugs with an improved efficacy, improved therapeutic index, and utility for treatment of new clinical indications. Duloxetine, a dual action transporter reuptake inhibitor, is a selective inhibitor for serotonin transporter protein and norepinephrine transporter protein reuptake (Sorbera et al., Drugs of the Future, 25(9):907-916 (2000), which is hereby incorporated by reference in its entirety) and has been marketed for the treatment of depression and diabetic peripheral neuropathic pain. In clinical studies, researchers attribute the effect of the medication on a broad spectrum of depression symptoms, which include emotional and painful physical symptoms as well as anxiety, to its dual reuptake inhibition of both serotonin and norepinephrine. Venlafaxine, which is also reported to be a selective serotonin and norepinephrine reuptake inhibitor (SNRI class), has been reported to exhibit a more rapid onset of action. The late onset of action has been a drawback with the first generation antidepressants, i.e., the single action serotonin selective reuptake inhibitors (SSRI class). For example, PROZAC®, the prototype drug in this class, can take four weeks or longer for full anti-depressive activity to take effect.
Atomoxetine (STRATTERA®), a norepinephrine selective transporter reuptake inhibitor, has been marketed for the treatment of ADHD. Unlike RITALIN®, one of the most frequently used drugs for treatment of ADHD, atomoxetine has little or no activity at the dopamine transporter. As a result, atomoxetine has the advantage that it is not scheduled as a controlled substance because it has minimal potential for substance abuse.
In a manner similar to the newer clinical agents like atomoxetine, duloxetine, and venlafaxine, the compounds of the present invention may exhibit improved efficacy towards broader symptoms of depression. The compounds of the present invention may also exhibit more rapid onset of action in the treatment of central nervous system (CNS) diseases, such as depression. In addition to providing improved efficacy, the compounds of the present invention may also exhibit fewer undesirable side effects. Finally, because the compounds of the present invention possess a diverse transporter reuptake inhibition profile, they are expected to be useful for a wider variety of CNS disorders.

Functional groups which may be rapidly transformed, by metabolic cleavage, in vivo form a class of groups reactive with the carboxyl group of the compounds of this invention. They include, but are not limited to such groups as alkanoyl (such as acetyl, propionyl, butyryl, and the like), unsubstituted and substituted aroyl (such as benzoyl and substituted benzoyl), alkoxycarbonyl (such as ethoxycarbonyl), trialkylsilyl (such as trimethyl- and triethysilyl), monoesters formed with dicarboxylic acids (such as succinyl), and the like. Because of the ease with which the metabolically cleavable groups of the compounds useful according to this invention are cleaved in vivo, the compounds bearing such groups act as pro-drugs. The compounds bearing the metabolically cleavable groups have the advantage that they may exhibit improved bioavailability as a result of enhanced solubility and/or rate of absorption conferred upon the parent compound by virtue of the presence of the metabolically cleavable group. A thorough discussion of prodrugs is provided in the following: Bundgaard, ed., Design of Prodrugs, Elsevier (1985); Widder et al., Methods in Enzymology, ed., Academic Press, 42:309-396 (1985); “Design and Applications of Prodrugs,” Krogsgaard-Larsen, ed., A Textbook of Drug Design and Development, Chapter 5:113-191 (1991); Bundgaard, Advanced Drug Delivery Reviews, 8:1-38 (1992); Bundgaard et al., Journal of Pharmaceutical Sciences, 77:285 (1988); Nakeya et al., Chem Pharm Bull, 32:692 (1984); Higuchi, “Pro-drugs as Novel Delivery Systems” Roche, ed., A.C.S. Symposium Series, Vol. 14, and “Bioreversible Carriers in Drug Design” American Pharmaceutical Association and Pergamon Press (1987), which are hereby incorporated by reference in their entirety. Examples of prodrugs include, but are not limited to, acetate, formate and benzoate derivatives of alcohol and amine functional groups in the compounds of the invention.
The term “therapeutically effective amounts” is meant to describe an amount of compound of the present invention effective in increasing the levels of serotonin, norepinephrine or dopamine at the synapse and thus producing the desired therapeutic effect. Such amounts generally vary according to a number of factors well within the purview of ordinarily skilled artisans given the description provided herein to determine and account for. These include, without limitation: the particular subject, as well as its age, weight, height, general physical condition and medical history, the particular compound used, as well as the carrier in which it is formulated and the route of administration selected for it; and, the nature and severity of the condition being treated.
The term “pharmaceutical composition” means a composition comprising compounds of formulae I(A-D) and at least one component selected from the group comprising pharmaceutically acceptable carriers, diluents, adjuvants, excipients, or vehicles, such as preserving agents, fillers, disintegrating agents, wetting agents, emulsifying agents, suspending agents, sweetening agents, flavoring agents, perfuming agents, antibacterial agents, antifungal agents, lubricating agents and dispensing agents, depending on the nature of the mode of administration and dosage forms. Examples of suspending agents include ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, or mixtures of these substances. Prevention of the action of microorganisms can be ensured by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, for example sugars, sodium chloride and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the use of agents delaying absorption, for example, aluminum monostearate and gelatin. Examples of suitable carriers, diluents, solvents or vehicles include water, ethanol, polyols, suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. Examples of excipients include lactose, milk sugar, sodium citrate, calcium carbonate, and dicalcium phosphate. Examples of disintegrating agents include starch, alginic acids, and certain complex silicates. Examples of lubricants include magnesium stearate, sodium lauryl sulphate, talc, as well as high molecular weight polyethylene glycols.
The term “pharmaceutically acceptable” means it is, within the scope of sound medical judgment, suitable for use in contact with the cells of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio.
The term “pharmaceutically acceptable dosage forms” means dosage forms of the compound of the invention, and includes, for example, tablets, dragees, powders, elixirs, syrups, liquid preparations, including suspensions, sprays, inhalants tablets, lozenges, emulsions, solutions, granules, capsules and suppositories, as well as liquid preparations for injections, including liposome preparations. Techniques and formulations generally may be found in Remington's Pharmaceutical Sciences, 17th ed, Easton, Pa., Mack Publishing Company (1985), which is hereby incorporated by reference in its entirety.

Within these embodiments, the selection of a particular preferred substituent at any one of R1-R8 does not affect the selection of a substituent at any of the others of R1-R7. That is, preferred compounds provided herein have any of the preferred substituents at any of the positions. For example, as described hereinabove, R1 is preferably C1-C6 alkyl; the selection of R1 as any one of C1, C2, C3, C4, C5, or C6 alkyl, does not limit the choice of R2 in particular to any one of H, C1-C6 alkyl, or C1-C6 haloalkyl. Rather, for R1 as any of C1, C2, C3, C4, C5, or C6 alkyl, R2 is any of H, C1, C2, C3, C4, C5, or C6 alkyl or C1, C2, C3, C4, C5, or C6 haloalkyl. Similarly, the selection of R2 as any of H, C1, C2, C3, C4, C5, or C6 alkyl or C1, C2, C3, C4, C5, or C6 haloalkyl does not limit the selection of R3 in particular to any one of H, halogen, —OR11, —S(O)nR12, —CN, —C(O)R12, C1-C6 alkyl, C3-C6 cycloalkyl, C4-C7 cycloalkylalkyl, or substituted C4-C7 cycloalkylalkyl.
Single enantiomers, any mixture of enantiomers, including racemic mixtures, or diastereomers (both separated and as any mixtures) of the compounds of the present invention are also included within the scope of the invention.
The scope of the present invention also encompasses active metabolites of the present compounds.
Another embodiment of the present invention is a mixture of compounds of formulae I(A-D), where the compound of formulae I(A-D) is radiolabeled, i.e., where one or more of the atoms described are replaced by a radioactive isotope of that atom (e.g., C replaced by 14C and H replaced by 3H). Such compounds have a variety of potential uses, e.g., as standards and reagents in determining the ability of a potential pharmaceutical to bind to neurotransmitter proteins.
Another embodiment of the present invention is a pharmaceutical composition containing a therapeutically effective amount of the compound of formulae I(A-D), and a pharmaceutically acceptable carrier.
Another aspect of the present invention relates to a method of treating a disorder which is created by or is dependent upon decreased availability of serotonin, norepinephrine, or dopamine. The method involves administering to a patient in need of such treatment a therapeutically effective amount of a compound of formulae I(A-D), or a pharmaceutically acceptable salt thereof. The method of the present invention is capable of treating subjects afflicted with various neurological and psychiatric disorders including, without limitation: lower back pain, attention deficit hyperactivity disorder (ADHD), cognition impairment, anxiety disorders especially generalized anxiety disorder (GAD), panic disorder, bipolar disorder, also known as manic depression or manic-depressive disorder, obsessive compulsive disorder (OCD), posttraumatic stress disorder (PTSD), acute stress disorder, social phobia, simple phobias, pre-menstrual dysphoric disorder (PMDD), social anxiety disorder (SAD), major depressive disorder (MDD), postnatal depression, dysthymia, depression associated with Alzheimer's disease, Parkinson's disease, or psychosis, supranuclear palsy, eating disorders, especially obesity, anorexia nervosa, bulimia nervosa, and binge eating disorder, analgesia, substance abuse disorders (including chemical dependencies) such as nicotine addiction, cocaine addiction, alcohol and amphetamine addiction, Lesch-Nyhan syndrome, neurodegenerative diseases such as Parkinson's disease, late luteal phase syndrome or narcolepsy, psychiatric symptoms such as anger, rejection sensitivity, movement disorders such as extrapyramidal syndrome, Tic disorders and restless leg syndrome (RLS), tardive dyskinesia, supranuclear palsy, sleep related eating disorder (SRED), night eating syndrome (NES), stress urinary incontinence (SUI), migraine, neuropathic pain, especially diabetic neuropathy, fibromyalgia syndrome (FS), chronic fatigue syndrome (CFS), sexual dysfunction, especially premature ejaculation and male impotence, and thermoregulatory disorders (e.g., hot flashes associated with menopause).
The compounds provided herein are particularly useful in the treatment of these and other disorders due, at least in part, to their ability to selectively bind to the transporter proteins for certain neurochemicals with a greater affinity than to the transporter proteins for other neurochemicals.
In another embodiment of the present invention, the above method further involves administering a therapeutically effective amount of a serotonin 1A receptor antagonist or a pharmaceutically acceptable salt thereof. Suitable serotonin 1A receptor antagonists include WAY 100135 and spiperone.

No. 4,988,814 to Abou-Gharbia et al., which is hereby incorporated by reference in its entirety. Also, Cliffe et al., J Med Chem 36:1509-10 (1993), which is hereby incorporated by reference in its entirety, showed that the compound is a serotonin 1A antagonist. Spiperone (8-[4-(4-fluorophenyl)-4-oxobutyl]-1-phenyl-1,3,8-triazaspiro[4,5]decan-4-one) is a well-known compound and is disclosed in U.S. Pat.

It is appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination.
Compounds according to the invention, for example, starting materials, intermediates or products, are prepared as described herein or by the application or adaptation of known methods, by which is meant methods used heretofore or described in the literature.
Compounds useful according to the invention may be prepared by the application or adaptation of known methods, by which is meant methods used heretofore or described in the literature, for example those described by Larock, R. C., Comprehensive Organic Transformations, VCH publishers, (1989), which is hereby incorporated by reference in its entirety.
A compound of formulae I(A-D), including a group containing one or more nitrogen ring atoms, may be converted to the corresponding compound where one or more nitrogen ring atom of the group is oxidized to an N-oxide, preferably by reacting with a peracid, for example, peracetic acid in acetic acid or m-chloroperoxybenzoic acid in an inert solvent such as dichloromethane, at a temperature from about room temperature to reflux, preferably at elevated temperature.
In the reactions described hereinafter, it may be necessary to protect reactive functional groups, for example hydroxyl, amino, imino, thio, or carboxy groups, where these are desired in the final product, to avoid their unwanted participation in the reactions. Conventional protecting groups may be used in accordance with standard practice; for examples, see Green, Protective Groups in Organic Chemistry, John Wiley and Sons (1991) and McOmie, Protective Groups in Organic Chemistry, Plenum Press (1973), which are hereby incorporated by reference in their entirety.
In the reaction schemes described hereinafter, the synthesis of tetrahydrobenzo-1,4-diazepines of formulae I(A-D) functionalized at R4 with aryl, heteroaryl, or heterocylic groups is described. The synthesis of tetrahydrobenzo-1,4-diazepines of formulae I(A-D) functionalized at R3, R5 or R6 with aryl, heteroaryl, or heterocyclic groups may be achieved via similar routes, apparent to one skilled in the art of organic synthesis.
The novel tetrahydro-1,4-benzodiazepine reuptake inhibitors of formula (I; R4=aryl, heteroaryl, or heterocyclic) of the present invention may be prepared by several known methods, as reviewed by Walser A. and Fryer, R. I., Bicyclic Diazepines, Diazepines with an Additional Ring, Volume 50, John Wiley and Sons (1991), which is hereby incorporated by reference in its entirety. One method, described in the above-mentioned reference, is outlined below (Scheme 1). The treatment of appropriately substituted isatoic anhydrides of formula (II), several of which may be obtained from commercial sources, with amino esters of formula (III), such as, but not limited to, sarcosine methyl ester, yields the corresponding benzo-1,4-diazepine-2,5-diones of formula (IV). The reaction is carried out in a solvent such as, but not limited to pyridine, at elevated temperature up to the reflux point of the solvent employed. Reduction of benzo-1,4-diazepine-2,5-diones of formula (IV) to the tetrahydrobenzo-1,4-diazepines of formula (V) proceeds with reducing agents including, for example, lithium aluminum hydride. The reductions are carried out for a period of time between 4 to 8 hours at elevated temperature up to the reflux point of the solvent employed. One skilled in the art will understand the optimal combination of reducing agents and reaction conditions required, or may seek guidance from Larock, R. C., Comprehensive Organic Transformations, VCH Publishers (1989), which is hereby incorporated by reference in its entirety.




The compounds of formula (I; R4=aryl, heteroaryl) of the present invention may be prepared from the corresponding tetrahydrobenzo-1,4-diazepines of formula (V; R4=Br) by sequential N-arylation to install the substituents at the N-1 position, followed by either a second N-arylation, or a cross-coupling reaction, to install the substituent at the C-7 position.
Thus, tetrahydrobenzo-1,4-diazepines of formula (V; R4=Br) are first reacted with an appropriate haloarene or aryl or heteroaryl boronic acid, in the presence of a metal catalyst, with or without a base, in an inert solvent. Metal catalysts include, but are not limited to, salts or complexes of Cu or Pd (e.g., CuI, Cu(OAc)2, Pd(OAc)2, PdCl2(dppf), Pd2(dba)3). Bases may include, but are not limited to, triethylamine, and alkali metal alkoxides (preferably, potassium tert-butoxide). A supporting ligand, such as, but not limited to, X-Phos or BINAP, is often used. Inert solvents may include, but are not limited to, aromatic hydrocarbons (preferably, benzene or toluene), aliphatic alcohols (preferably, tert-butanol), and halogenated solvents (preferably, dichloromethane). Preferred reaction temperatures range from room temperature up to the boiling point of the solvent employed. The reactions may be run in conventional glassware or in a sealed reaction vessel.
The 1-aryl/heteroaryl-7-bromo-tetrahydrobenzo-1,4-diazepines obtained thus may be reacted with an appropriate amine, amide or lactam, in the presence of a metal catalyst, with or without a base in an inert solvent to give the benzo-1,4-diazepine compounds of formula (I; R4=aryl, heteroaryl) of the present invention. Metal catalysts include, but are not limited to, salts or complexes of Cu, Pd, or Ni (e.g., CuI, Cu(OAc)2, PdCl2(dppf), NiCl(OAc)2, Ni(COD)2). Bases may include, but are not limited to, alkali metal carbonates, alkali metal phosphates (preferably potassium phosphate), alkali metal alkoxides (preferably, sodium tert-butoxide), and alkali metal bis(trialkylsilyl)amides (preferably, lithium bis(trimethylsilyl)amide). A supporting ligand, such as, but not limited to L-proline or dimethylethylenediamine is often used. Inert solvents may include, but are not limited to, cyclic ethers (preferably, tetrahydrofuran or 1,4-dioxane), N,N-dialkylformamides (preferably, dimethylformamide), dialkylsulfoxides (preferably, dimethylsulfoxide), or aromatic hydrocarbons (preferably, benzene or toluene). Preferred reaction temperatures range from room temperature up to the boiling point of the solvent employed. The reactions may be run in conventional glassware or in a sealed reaction vessel.
The 1-aryl/heteroaryl-7-bromo-tetrahydrobenzo-1,4-diazepines obtained previously may also be reacted with appropriate aryl or heteroaryl boronic acids or aryl or heteroaryl boronic acid esters of formula R4—Z, where Z is equivalent to B(OH)2 or B(ORa)(ORb) (where Ra and Rb are lower alkyl, i.e., C1-C6, or taken together, Ra and Rb are lower alkylene, i.e., C2-C12) and R4 is the corresponding aryl or heteroaryl group, in the presence of a metal catalyst with or without a base in an inert solvent to give the benzo-1,4-diazepine compounds of formula (I; R4=aryl, heteroaryl) of the present invention. Metal catalysts include, but are not limited to, salts or phosphine complexes of Cu, Pd, or Ni (e.g., Cu(OAc)2, PdCl2 (PPh3)2, NiCl2 (PPh3)2, Pd(PPh3)4). Bases may include, but are not limited to, alkaline earth metal carbonates, alkaline earth metal bicarbonates, alkaline earth metal hydroxides, alkali metal carbonates, alkali metal bicarbonates, alkali metal hydroxides, alkali metal hydrides (preferably sodium hydride), alkali metal alkoxides (preferably sodium methoxide or sodium ethoxide), alkaline earth metal hydrides, alkali metal dialkylamides (preferably lithium diisopropylamide), alkali metal bis(trialkylsilyl)amides (preferably sodium bis(trimethylsilyl)amide), trialkyl amines (preferably diisopropylethylamine or triethylamine) or aromatic amines (preferably pyridine). Inert solvents may include, but are not limited to acetonitrile, dialkyl ethers (preferably diethyl ether), cyclic ethers (preferably tetrahydrofuran or 1,4-dioxane), N,N-dialkylacetamides (preferably dimethylacetamide), N,N-dialkylformamides (preferably dimethylformamide), dialkylsulfoxides (preferably dimethylsulfoxide), aromatic hydrocarbons (preferably benzene or toluene) or haloalkanes (preferably methylene chloride). Preferred reaction temperatures range from room temperature up to the boiling point of the solvent employed. The reactions may be run in conventional glassware or in one of many commercially available parallel synthesizer units. Non-commercially available boronic acids or boronic acid esters may be obtained from the corresponding optionally substituted aryl halide as described by Gao et al., Tetrahedron, 50:979-988 (1994), which is hereby incorporated by reference in its entirety.
It will also be appreciated by one skilled in the art that the 1-aryl/heteroaryl-7-bromo-tetrahydrobenzo-1,4-diazepines obtained previously may be converted to the boronic acid or boronate ester and subsequently treated with the desired optionally substituted aryl or heteroaryl halide in discrete steps or in tandem as described by Baudoin et al., J. Org. Chem. 67:1199-1207 (2002), which is hereby incorporated by reference in its entirety.
Alternatively, the 1-aryl/heteroaryl-7-bromo-tetrahydrobenzo-1,4-diazepines described previously may be coupled with aryl or heteroaryl stannanes to yield the benzo-1,4-diazepine compounds of formula (I; R4=aryl, heteroaryl) of the present invention. One skilled in the art will be familiar with the catalysts and reaction conditions that need to be employed to effect the desired transformation.
In addition, compounds of formula (V; R4=Br) may be protected at the N-1 position using an appropriate protecting group, such as, but not limited to, acetyl and benzoyl, to give compounds of formula (VI; Y=acetyl or benzoyl). The acyl protecting group may be introduced on reaction of compounds of formula (V; R=Br) with an acyl chloride, such as, but not limited to, acetyl chloride or benzoyl chloride, in the presence of a base, such as, but not limited to triethylamine, or pyridine, in an appropriate inert solvent. Inert solvents include, for example, dichloromethane and dichloroethane. The choice of protecting groups will be evident to one skilled in the art; for additional guidance, one may also consult Green, Protective Groups in Organic Chemistry, John Wiley and Sons (1991) and McOmie, Protective Groups in Organic Chemistry, Plenum Press (1973), which are hereby incorporated by reference in their entirety.
The compounds of formula (VI; Y=acetyl or benzoyl; R4=Br) may then be converted to the benzo-1,4-diazepine compounds of formula (I; R4=aryl, heteroaryl) of the present invention by sequential cross coupling or N-arylation to install the substituents at the C-7 position, following by removal of the protecting group, and a second N-arylation step to install the substituent at the N-1 position. Accordingly, compounds of formula (VI; Y=acetyl or benzoyl; R4=Br) may be reacted with aryl or heteroaryl boronic acids, aryl or heteroaryl boronic acid esters, aryl or heteroaryl stannanes, amines, amides or lactams as described above. Removal of the acyl protection group may be effected by treatment with a strong acid, such as hydrochloric acid, at elevated temperatures. Finally, a second N-arylation using an appropriate aryl or heteroaryl halide, under the reaction conditions described above gives the tetrahydrobenzo-1,4-diazepines of formulae I(A-D) of the present invention.
Compounds of formulae I(A-D) may be obtained in enantiomerically pure (R) and (S) form by crystallization with chiral salts as well known to one skilled in the art, or alternatively, may be isolated through chiral HPLC employing commercially available chiral columns.
It will be appreciated that compounds according to the present invention may contain asymmetric centers. These asymmetric centers may independently be in either the R or S configuration and such compounds are able to rotate a plane of polarized light in a polarimeter. If said plane of polarized light is caused by the compound to rotate in a counterclockwise direction, the compound is said to be the (−) stereoisomer of the compound. If said plane of polarized light is caused by the compound to rotate in a clockwise direction, the compound is said to be the (+) stereoisomer of the compound. It will be apparent to those skilled in the art that certain compounds useful according to the invention may also exhibit geometrical isomerism. It is to be understood that the present invention includes individual geometrical isomers and stereoisomers and mixtures thereof, including racemic mixtures, of compounds of formulae I(A-D) hereinabove. Such isomers can be separated from their mixtures, by the application or adaptation of known methods, for example chromatographic techniques and recrystallization techniques, or they are separately prepared from the appropriate isomers of their intermediates.
Radiolabelled compounds of the invention are synthesized by a number of means well known to those of ordinary skill in the art, e.g., by using starting materials incorporating therein one or more radioisotopes. Compounds of the present invention where a stable radioisotope, such as carbon-14, tritium, iodine-121, or another radioisotope, has been introduced synthetically are useful diagnostic agents for identifying areas of the brain or central nervous system that may be affected by disorders where norepinephrine, dopamine, or serotonin transporters and their uptake mechanism are implicated.
The present invention provides compositions containing the compounds described herein, including, in particular, pharmaceutical compositions comprising therapeutically effective amounts of the compounds and pharmaceutically acceptable carriers.
It is a further object of the present invention to provide kits having a plurality of active ingredients (with or without carrier) which, together, may be effectively utilized for carrying out the novel combination therapies of the invention.
It is another object of the invention to provide a novel pharmaceutical composition which is effective, in and of itself, for utilization in a beneficial combination therapy because it includes a plurality of active ingredients which may be utilized in accordance with the invention.
The present invention also provides kits or single packages combining two or more active ingredients useful in treating the disease. A kit may provide (alone or in combination with a pharmaceutically acceptable diluent or carrier) the compounds of formulae I(A-D), and the additional active ingredient (alone or in combination with diluent or carrier) selected from a serotonin 1A receptor antagonist, a selective neurokinin-1 receptor antagonist, and a norepinephrine precursor.
In practice, the compounds of the present invention may generally be administered parenterally, intravenously, subcutaneously, intramuscularly, colonically, nasally, intraperitoneally, rectally, or orally.
The products according to the invention may be presented in forms permitting administration by the most suitable route and the invention also relates to pharmaceutical compositions containing at least one product according to the invention which are suitable for use in human or veterinary medicine. These compositions may be prepared according to the customary methods, using one or more pharmaceutically acceptable adjuvants or excipients. The adjuvants comprise, inter alia, diluents, sterile aqueous media, and the various non-toxic organic solvents. The compositions may be presented in the form of tablets, pills, granules, powders, aqueous solutions or suspensions, injectable solutions, elixirs or syrups, and can contain one or more agents chosen from the group comprising sweeteners, flavorings, colorings, or stabilizers in order to obtain pharmaceutically acceptable preparations.
The choice of vehicle and the content of active substance in the vehicle are generally determined in accordance with the solubility and chemical properties of the product, the particular mode of administration and the provisions to be observed in pharmaceutical practice. For example, excipients such as lactose, sodium citrate, calcium carbonate, dicalcium phosphate and disintegrating agents such as starch, alginic acids and certain complex silicates combined with lubricants such as magnesium stearate, sodium lauryl sulfate and talc may be used for preparing tablets. To prepare a capsule, it is advantageous to use lactose and high molecular weight polyethylene glycols. When aqueous suspensions are used they can contain emulsifying agents or agents which facilitate suspension. Diluents such as sucrose, ethanol, polyethylene glycol, propylene glycol, glycerol, and chloroform or mixtures thereof may also be used.
For parenteral administration, emulsions, suspensions or solutions of the products according to the invention in vegetable oil, for example sesame oil, groundnut oil, or olive oil, or aqueous-organic solutions such as water and propylene glycol, injectable organic esters such as ethyl oleate, as well as sterile aqueous solutions of the pharmaceutically acceptable salts, are used. The solutions of the salts of the products according to the invention are especially useful for administration by intramuscular or subcutaneous injection. The aqueous solutions, also comprising solutions of the salts in pure distilled water, may be used for intravenous administration with the proviso that their pH is suitably adjusted, that they are judiciously buffered and rendered isotonic with a sufficient quantity of glucose or sodium chloride and that they are sterilized by heating, irradiation or microfiltration.
Suitable compositions containing the compounds of the present invention may be prepared by conventional means. For example, compounds of the present invention may be dissolved or suspended in a suitable carrier for use in a nebulizer or a suspension or solution aerosol, or may be absorbed or adsorbed onto a suitable solid carrier for use in a dry powder inhaler.
Solid compositions for rectal administration include suppositories formulated in accordance with known methods and containing at least one the compound of formulae I(A-D).
The percentage of active ingredient in the compositions of the present invention may be varied, it being necessary that it should constitute a proportion such that a suitable dosage shall be obtained. Obviously, several unit dosage forms may be administered at about the same time. The dose employed will be determined by the physician, and depends upon the desired therapeutic effect, the route of administration and the duration of the treatment, and the condition of the patient. In the adult, the doses are generally from about 0.01 to about 100 mg/kg body weight, preferably about 0.01 to about 10 mg/kg body weight per day by inhalation, from about 0.01 to about 100 mg/kg body weight, preferably 0.1 to 70 mg/kg body weight, more especially 0.5 to 10 mg/kg body weight per day by oral administration, and from about 0.01 to about 50 mg/kg body weight, preferably 0.01 to 10 mg/kg body weight per day by intravenous administration. In each particular case, the doses will be determined in accordance with the factors distinctive to the subject to be treated, such as age, weight, general state of health and other characteristics which can influence the efficacy of the medicinal product.
The products according to the present invention may be administered as frequently as necessary in order to obtain the desired therapeutic effect. Some patients may respond rapidly to a higher or lower dose and may find much weaker maintenance doses adequate. For other patients, it may be necessary to have long-term treatments at the rate of 1 to 4 doses per day, in accordance with the physiological requirements of each particular patient. Generally, the active product may be administered orally 1 to 4 times per day. It goes without saying that, for other patients, it will be necessary to prescribe not more than one or two doses per day.
The present invention provides compounds which inhibit synaptic norepinephrine, dopamine, and serotonin uptake and are, therefore, believed to be useful in treating a disorder which is created by or is dependent upon decreased availability of serotonin, norepinephrine or dopamine. Although the compounds of formulae I(A-D) inhibit synaptic norepinephrine, dopamine, and serotonin uptake, in any individual compound, these inhibitory effects may be manifested at the same or vastly different concentrations or doses. As a result, some compounds of formulae I(A-D) are useful in treating such a disorder at doses at which synaptic norepinephrine uptake may be substantially inhibited but at which synaptic serotonin uptake or dopamine uptake is not substantially inhibited, or vice versa. Also, some compounds of formulae I(A-D) are useful in treating such a disorder at doses at which synaptic dopamine uptake may be substantially inhibited but at which synaptic norepinephrine or serotonin uptake is not substantially inhibited, or vice versa. And, conversely, some compounds of formulae I(A-D) are useful in treating such a disorder at doses at which synaptic serotonin uptake may be substantially inhibited but at which synaptic norepinephrine or dopamine uptake is not substantially inhibited, or vice versa. Other compounds of formulae I(A-D) are useful in treating such a disorder at doses at which synaptic norepinephrine, dopamine, and serotonin uptake are substantially inhibited.
The present invention provides compounds where the inhibitory effects on serotonin and norepinephrine uptake occurs at similar or even the same concentrations of these compounds, while the effects on inhibition of dopamine uptake occurs at vastly different concentrations or doses. As a result, some compounds of formulae I(A-D) are useful in treating such a disorder at doses at which synaptic serotonin and norepinephrine uptake may be substantially inhibited but at which synaptic dopamine uptake is not substantially inhibited, or vice versa.

The present invention provides compounds where the inhibitory effects on norepinephrine, dopamine and serotonin uptake occur at similar or even the same concentration. As a result, some compounds of formulae I(A-D) are useful in treating such a disorder at doses at which synaptic norepinephrine, dopamine, and serotonin uptake may all be substantially inhibited.
The concentrations or doses at which a test compound inhibits synaptic norepinephrine, dopamine, and serotonin uptake is readily determined by the use of standard assay and techniques well known and appreciated by one of ordinary skill in the art. For example, the degree of inhibition at a particular dose in rats can be determined by the method of Dudley, J Pharmacol Exp Ther 217:834-840 (1981), which is hereby incorporated by reference in its entirety.
The therapeutically effective inhibitory dose is one that is effective in substantially inhibiting synaptic norepinephrine uptake, synaptic dopamine uptake, or synaptic serotonin uptake or inhibiting the synaptic uptake of two or more of norepinephrine, dopamine and serotonin uptake. The therapeutically effective inhibitory dose can be readily determined by those skilled in the art by using conventional range finding techniques and analogous results obtained in the test systems described above.
Compounds of this invention provide a particularly beneficial therapeutic index relative to other compounds available for the treatment of similar disorders. Without intending to be limited by theory, it is believed that this is due, at least in part, to some of the compounds having higher binding affinities for one or two of the neurotransmitter transporters, e.g., selectivity towards the norepinephrine transporter protein (“NET”) over the transporters for other neurochemicals, e.g., the dopamine transporter protein (“DAT”) and the serotonin transporter protein (“SERT”).
Other compounds of the present invention may demonstrate selectivity towards the SERT over the transporters for other neuro chemicals, e.g., the DAT and the NET.
Still other compounds of the present invention may demonstrate selectivity towards the DAT over the transporters for other neurochemicals, e.g., the SERT and the NET.
Other compounds of the present invention may demonstrate selectivity towards the SERT and the NET over the transporter for other neurochemical, e.g., the DAT.
Still other compounds of the present invention may demonstrate selectivity towards the SERT and the DAT over the transporter for other neurochemical, e.g., the NET.
Still other compounds of the present invention may demonstrate selectivity towards the NET and the DAT over the transporter for other neurochemical, e.g., the SERT.
Finally other compounds possess nearly identical affinity towards the NET, the DAT, and the SERT.
Binding affinities are demonstrated by a number of means well known to ordinarily skilled artisans, including, without limitation, those described in the Examples section hereinbelow. Briefly, for example, protein-containing extracts from cells, e.g., HEK293E cells, expressing the transporter proteins are incubated with radio labelled ligands for the proteins. The binding of the radio ligands to the proteins is reversible in the presence of other protein ligands, e.g., the compounds of the present invention; said reversibility, as described below, provides a means of measuring the compounds' binding affinities for the proteins (Ki or IC50). A higher Ki or IC50 value for a compound is indicative that the compound has less binding affinity for a protein than is so for a compound with a lower Ki or IC50; conversely, lower Ki or IC50 values are indicative of greater binding affinities.
Accordingly, the difference in compound selectivity for proteins is indicated by a lower Ki or IC50 for the protein for which the compound is more selective, and a higher Ki or IC50 for the protein for which the compound is less selective. Thus, the higher the ratio in Ki or IC50 values of a compound for protein A over protein B, the greater is the compounds' selectivity for the latter over the former (the former having a higher Ki or IC50 and the latter a lower Ki or IC50 for that compound). Compounds provided herein possess a wide range of selectivity profiles for the norepinephrine, dopamine, and serotonin transporters as reflected by the ratios of the experimentally determined Ki or IC50 values.
Selected compounds (“mono action transporter reuptake inhibitors”) of the present invention have potent binding affinity for each of the biogenic amine transporters NET, DAT or SERT. For example, selected compounds of the present invention possess potent (NET Ki or IC50<100 nM) and selective binding affinity for NET, where the Ki or IC50 ratio of DAT/NET and SERT/NET is greater than 10:1. Other selected compounds of the present invention possess potent (SERT Ki or IC50<100 nM) and selective binding affinity for SERT, where the Ki or IC50 ratio of NET/SERT and DAT/SERT is greater than 10:1. Other selected compounds of the present invention possess potent (DAT Ki or IC50<100 nM) and selective binding affinity for DAT, where the Ki or IC50 ratio of NET/DAT and SERT/DAT is greater than 10:1.
Selected compounds (“dual action transporter reuptake inhibitors”) of the present invention have potent binding affinity for two of the biogenic amine transporters, NET, DAT or SERT. For example, selected compounds of the present invention possess potent (NET & SERT Ki or IC50 values<100 nM) and selective binding affinity for NET and SERT, where the Ki ratio of DAT/NET and DAT/SERT is greater than 10:1 while the Ki or IC50 ratio of SERT/NET or NET/SERT is less than 10:1. Other selected compounds of the present invention possess potent (NET & DAT Ki or IC50 values<100 nM) and selective binding affinity for NET and DAT, where the Ki ratio of SERT/NET and SERT/DAT is greater than 10:1 while the Ki or IC50 ratio of DAT/NET or NET/DAT is less than 10:1. Other selected compounds of this invention possess potent (DAT & SERT Ki or IC50 values<100 nM) and selective binding affinity for DAT and SERT, where the Ki or IC50 ratio of NET/DAT and SERT/DAT is greater than 10:1 while the Ki or IC50 ratio of SERT/NET or NET/SERT is less than 10:1.
Selected compounds (“triple action transporter reuptake inhibitors”) of the present invention have potent binding affinity simultaneously for all three of the biogenic amine transporters, NET, DAT or SERT. For example, selected compounds of this invention possess potent (NET, DAT & SERT Ki or IC50 values<100 nM) where the Ki or IC50 ratios of NET/DAT, NET/SERT, DAT/NET, DAT/SERT, SERT/NET and SERT/DAT are all less than 10:1.
Selected compounds of the present invention have potent binding affinity (Ki or IC50 values<100 nM) for one, two, or three of the biogenic amine transporters, NET, DAT and SERT where the Ki or IC50 ratios for any of NET/SERT, NET/DAT, DAT/NET, DAT/SERT, SERT/NET, and SERT/DAT fall outside of the bounds defined for the “Mono-, Dual or Triple action transporter reuptake inhibitors” defined above.
Selected compounds of the present invention have less potent binding affinity (Ki or IC50 values between 100 nM and 1000 nM) for one, two, or three of the biogenic amine transporters, NET, DAT and SERT, where the Ki or IC50 ratios for any of NET/SERT, NET/DAT, DAT/NET, DAT/SERT, SERT/NET, and SERT/DAT fall within the bounds defined for the “mono, dual, or triple action transporter reuptake inhibitors” defined above.
Finally, selected compounds of the present invention have less potent binding affinity (Ki or IC50 values between 100 nM and 1000 nM) for one, two, or three of the biogenic amine transporters, NET, DAT, and SERT, where the Ki or IC50 ratios for any of NET/SERT, NET/DAT, DAT/NET, DAT/SERT, SERT/NET, and SERT/DAT fall outside of the bounds defined for the “mono, dual, or triple action transporter reuptake inhibitors” defined above.

Preparation of 1-(1-fluoronaphthalen-2-yl)-4-methyl-7-(pyridazin-3-yl)-2,3,4,5-tetrahydro-1H-benzo[e][1,4]diazepine, L-tartrate salt
Step A: A mixture of isatoic anhydride (16.30 g, 100 mmol), sarcosine ethyl ester (15.40 g, 100 mmol) and pyridine (40 mL) was heated under reflux for 7 hours. After cooling, ethanol was added to the mixture until a precipitate was formed. Filtration gave the lactam as an off-white solid (11.04 g, 58%): ESI MS m/z 191 [M+H]+.
Step B: To a suspension of lithium aluminum hydride (9.92 g, 261 mmol) in THF (250 mL) at 0° C. was added the lactam (11.04 g, 58.1 mmol) from Step A above. The mixture was then refluxed for 7 hours after the addition was completed. The cooled reaction mixture was quenched with water (200 mL) carefully and the resulting mixture was stirred at room temperature for 1 hour. The mixture was then extracted with methylene chloride (3×100 mL). The combined organic layer was dried over sodium sulfate, filtered and concentrated in vacuo to give the benzodiazepine (8.90 g, 95%) as a light yellow oil: ESI MS m/z 163 [M+H]+.
Step C: To a solution of the benzodiazepine (8.90 g, 54.9 mmol) from Step B above in DMF (100 mL) at 0° C. was added N-bromosuccinimide (10.3 g, 57.7 mmol). The mixture was stirred at 0° C. for 3 hours. The solvent was then evaporated in vacuo and the residue was dissolved in ethyl acetate (500 mL). The mixture was washed with 1 N NaOH, dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography (90:10 methylene chloride/methanol) to give the desired bromobenzodiazepine (9.90 g, 75%) as a yellow solid: 1H NMR (CDCl3, 500 MHz) δ 7.23 (s, 1H), 7.17 (d, J=8.3 Hz, 1H), 6.61 (d, J=8.3 Hz, 1H), 3.86 (br, 1H), 3.63 (s, 2H), 3.13-3.11 (m, 2H), 2.87-2.85 (m, 2H), 2.38 (s, 3H); ESI MS m/z 241 [M+H]+.
Step D: To a solution of the bromobenzodiazepine (4.80 g, 20 mmol) from Step C above and pyridine (3.8 mL) in methylene chloride (50 mL) at 0° C. was added benzoyl chloride (6.18 g, 44.0 mmol) dropwise. The mixture was stirred at 0° C. for 1 hour, at which time a white precipitate was formed. Saturated NaHCO3 (50 mL) was added to quench the reaction, and the mixture was brought to pH 9-10 by adding 2 N NaOH. The two phases were separated, and the organic phase was dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography (ethyl acetate, then 90:10 ethyl acetate/methanol) to give the benzoylbenzodiazepine (6.18 g, 90%) as a yellow solid: 1H NMR (CDCl3, 300 MHz) δ 7.56 (s, 1H), 7.33-7.17 (m, 6H), 6.55 (d, J=7.8 Hz, 1H), 5.11 (br, 1H), 4.22 (br, 1H), 4.03 (br, 1H), 3.27 (br, 3H), 2.65 (s, 3H); ESI MS m/z 345 [M+H]+.

The mixture was degassed with nitrogen (3×) and then stirred at 60° C. overnight. The mixture was then cooled to room temperature, and cesium carbonate (17.5 g, 53.7 mmol), 3,6-dichloro-pyridazine (4.00 g, 26.9 mmol) and water (41 mL) were added to it. The mixture was degassed with nitrogen (3×) and then stirred at 60° C. for 3 hours. After cooling, the mixture was partitioned between methylene chloride and water. The aqueous phase was extracted with methylene chloride (3×100 mL). The combined organic extract was dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography (100:0 to 85:15 ethyl acetate/methanol) to yield the desired chloropyridazinobenzodiazepine (5.64 g, 83%) as a grey solid: 1H NMR (CDCl3, 500 MHz) δ 8.07 (s, 1H), 7.75 (d, J=9.0 Hz, 1H), 7.59 (s, 1H), 7.54 (d, J=9.0 Hz, 1H), 7.28-7.18 (m, 5H), 6.77 (s, 1H), 5.01 (br, 1H), 4.12 (br, 1H), 3.91 (br, 1H), 3.00 (m, 3H), 2.47 (s, 3H); ESI MS m/z 379 [M+H]+.

After cooling, the mixture was filtered through a celite pad and concentrated in vacuo. The crude product was partitioned between water (50 mL) and methylene chloride (50 mL). The aqueous phase was basified to pH 9 by adding 2 N NaOH. The two phases were separated and the aqueous phase was extracted with methylene chloride (50 mL). The combined organic extract was dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography (100:0 to 90:10 methylene chloride/methanol) to yield the desired pyridazinobenzodiazepine (1.60 g, 91%) as a off-white solid: 1H NMR (CDCl3, 500 MHz) δ 9.14 (s, 1H), 8.12 (s, 1H), 7.78 (d, J=8.4 Hz, 1H), 7.61 (br, 1H), 7.52 (d, J=8.6 Hz, 1H), 7.28-7.18 (m, 5H), 6.78 (br, 1H), 5.02 (br, 1H), 4.15 (br, 1H), 3.92 (br, 1H), 3.14-3.07 (m, 3H), 2.47 (s, 3H); ESI MS m/z 345 [M+H]+.
Step G: A mixture of the pyridazinobenzodiazepine (1.58 g, 4.59 mmol) from Step F above and 6 N HCl (10 mL) was refluxed for 4 hours. The solvents were removed in vacuo, and the residue was basified to pH 9 by adding 2 N NaOH. The mixture was extracted with methylene chloride (3×50 mL). The combined extract was dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography (80:19:1 methylene chloride/methanol/ammonium hydroxide) to yield the desired benzodiazepine (1.12 g, quantitative) as a yellow solid: 1H NMR (500 MHz, CDCl3) δ 9.07 (s, 1H), 7.91 (s, 1H), 7.84 (d, J=8.2 Hz, 1H), 7.78 (d, J=8.4 Hz, 1H), 7.47-7.44 (m, 1H), 6.86 (d, J=8.2 Hz, 1H), 4.10 (br, 1H), 3.83 (s, 2H), 3.24-3.23 (m, 2H), 2.92-2.90 (m, 2H), 2.44 (s, 3H); ESI MS m/z 241 [M+H]+.

The reaction was conducted under microwave irradiation (200 W) at 120° C. for 20 minutes. The mixture was filtered through a celite pad and washed with methylene chloride. The filtrate was concentrated in vacuo and the residue was purified by column chromatography (methylene chloride, then 10:1 methylene chloride/methanol) to yield the desired benzodiazepine (39 mg, 43%) as a colorless oil: 1H NMR (500 MHz, CDCl3) δ 9.09 (s, 1H), 8.06 (m, 2H), 7.80-7.65 (m, 3H), 7.61 (d, J=8.8 Hz, 1H), 7.55-7.52 (m, 1H), 7.48-7.45 (m, 2H), 7.30 (t, J=8.2 Hz, 1H), 6.77 (d, J=8.4 Hz, 1H), 4.01 (s, 2H), 3.90-3.88 (m, 2H), 2.96-2.94 (m, 2H), 2.50 (s, 3H); ESI MS m/z 385 [M+H]+.
Step I: To a solution of the benzodiazepine (39 mg, 0.1 mmol) from Step H above in methanol (1 mL) was added L-tartaric acid (15 mg, 0.1 mmol).

Data Analysis
The raw data is normalized to percent inhibition using control wells defining 0% (DMSO only) and 100% (selective inhibitor) inhibition which are run on each plate. Each plate is run in triplicate, and the concentration response curve thus generated is fit using the four-parameter dose response equation, Y=Bottom+(Top-Bottom)/(1+10^((LogIC50−X)*HillSlope)) in order to determine the IC50 value for each compound. The radio ligand concentration chosen for each assay corresponds to the Kd concentration determined through saturation binding analysis for each assay.
