Description:
RELATED APPLICATION  
      This application claims the benefit of U.S. provisional patent application Ser. No. 60/696,214 filed on Jul. 1, 2005. 
    
    
     TECHNICAL FIELD OF THE INVENTION  
      The present invention relates to an aryloxypropanamine in which one or more hydrogen attached to a carbon has been replaced with deuterium. These heavy atom-containing aryloxypropanamines of the invention are inhibitors of serotonin and norepinephrine uptake and possess unique biopharmaceutical and pharmacokinetic properties compared to the corresponding all-light atoms isotopologues. The invention further provides compositions comprising these heavy atom-containing aryloxypropanamines and methods of treating diseases and conditions that have been linked to reduced neurotransmission of serotonin and/or norepinephrine. The invention also provides methods of using the compounds of this invention to determine metabolic liabilities of the all-light atom species and their extraction efficiencies from biological milieu.  
     BACKGROUND OF THE INVENTION  
      Aryloxypropanamines, of the formula:  
                 
 
 R 1  is C 5 -C 7  cycloalkyl, thienyl, halothienyl, (C 1 -C 4  alkyl) thienyl, furanyl, pyridyl or thiazolyl; 
 
 Ar is  
                 
 
 each of R 2  and R 3  independently is hydrogen or methyl; each R 4  independently is halo, C 1 -C 4  alkyl, C 1 -C 3  alkoxy or trifluoromethyl; each R 5  independently is halo, C 1 -C 4  alkyl or trifluoromethyl; m is 0, 1 or 2; n is 0 or 1; and the pharmaceutically acceptable acid addition salts thereof are disclosed as useful inhibitors of serotonin (5-HT) and norepinephrine (NE) uptake, with utility as psychotropic agents, particularly antidepressants (Robertson D W et. al. U.S. Pat. No. 5,023,269 to Eli Lilly). 
 
      In particular, Compound A, chemically described variously as (+)-(S)-N-methyl-γ-(1-naphthyloxy)-2(thiophenenepropylamine hydrochloride; (S)-N-methyl-3-(naphthalen-1-yloxy)-3-(thiophen-2-yl)propan-1-amine hydrochloride; and (+)-(S)-N-methyl-N-[3-(naphthalen-1-yloxy)-3-(2-thienyl)propyl]amine hydrochloride; has been approved by the US Food and Drug Administration for the treatment of depression and diabetic neuropathy pain (New Drug Application No. 021427 http://www.fda.gov/cder/foi/label/2004/217331bl.pdf)  
                 
 
      Compound A was the first agent to be approved for the latter indication, and provides important and substantial therapeutic benefits (FDA Press Release P04-87, http://www.fda.gov/bbs/topics/news/2004/NEW01113.html). Compound A is also useful for the treatment of attention-deficit/hyperactivity disorder, fibromyalgia, psoriasis, interstitial cystitis, incontinence, and providing cardiovascular benefit through reduction of platelet activation state (Heiligenstein J H et. al. U.S. Pat. No. 5,696,168 to Eli Lilly; Thor K B U.S. Pat. No. 5,744,474 to Eli Lilly; Iyengar S et. al. U.S. Pat. No. 6,150,396 to Eli Lilly; Goldstein D J et. al., U.S. Pat.

      Combinations with additional agents are known to further extend the utility of Compound A in the treatment or prevention of depression, obsessive-compulsive disease, aggressive disorder, premature ejaculation, cardiovascular disease, urinary tract disorders, psychosis, acute mania, anxiety, pain, and sleep disorders, by reducing its associated gastrointestinal side-effects or by potentiating its drug activity, (Wong D T et al., U.S. Pat.

No. 6,878,732 to Schering Corporation). Each of the patents cited in this disclosure are incorporated in their entirety herein by reference.  
      Compound A has been characterized in rodent models as inhibiting neural cell firing by reducing reuptake of 5-HT. It also is a high affinity NE reuptake inhibitor, but lacks affinity for central monoamine receptors (Wong D T et. al., Neuropsychopharmacology 1993 8: 23; Fuller R W et. al., J. Pharmacol. Exp. Ther. 1994 269: 132; Kasamo K et. al., J. Pharmacol. Exp. Ther. 1996 277: 278.) In the forced swim test animal model, Compound A demonstrates potent attenuation of immobility, a predictive model for antidepressant activity (Karpa K D et. al., CNS Drug Rev. 2002 8: 361; Reneric J P and Lucki I, Psychopharmacology 1998 136: 190). In humans, Compound A recapitulates the preclinically observed inhibition of 5-HT and NE reuptake, and demonstrates potent antidepressant activity (Chalon S A et. al., Neuropsychopharmacology 2003 28:1685.  
      Following oral administration to humans, Compound A is rapidly and extensively metabolized by predominantly oxidative mechanisms (Lantz R A, et. al., Drug Metab. Dispos. 2003 31:1142), the major initial metabolites being ring oxidation on the naphthylenyl ring, followed by secondary ring oxidation and Phase II conjugations and urinary excretion. The conjugated metabolites and major identified ring oxidation products have substantially attenuated or immeasurably poor activity against the transporters believed to be responsible for the neurological activity of Compound A (Kuo F, et. al., Bioorg. Med. Chem. Lett. 2004 14: 3481). This oxidation is reportedly mediated mainly by two isozymes of cytochrome P450, namely, CYP2D6 and CYP1A2 (New Drug Application No. 021427 dated 9/30/04: http://www.fda.gov/cder/foi/label/2004/217331bl.pdf). Demethylation of the amine group also occurs to an unknown extent, forming an inactive metabolite. Following administration of radiolabeled Compound A, only approximately 3% of the circulating radioactivity, on an area under the time-plasma concentration curve (AUC) basis, was attributable to parent drug, indicating the extent to which metabolism affects exposure to the parent drug. Thus, it is clear that the biochemical oxidative lability of Compound A is a factor in limiting this drug&#39;s potency and preventing lower doses from exhibiting sufficient efficacy.  
      It is therefore desirable to create a compound displaying the beneficial activities of Compound A, but that will display a reduced rate of metabolism following administration to a patient. Finding a way to reduce one or both of oxidation at the naphthylenyl ring and oxidative N-demethylation should create a particularly useful new chemical entity.  
     SUMMARY OF THE INVENTION  
      The present invention solves the problems set forth above by providing a compound of Formula I:  
                 
 
 or a pharmaceutically acceptable acid addition salt thereof, wherein: 
      each Y is independently selected from H or deuterium;     R 1  is C 5 -C 7  cycloalkyl, thienyl, halothienyl, (C 1 -C 4  alkyl) thienyl, furanyl, pyridyl, thiazolyl;     Ar is  
                 
        each R 4  is independently selected from halo, C 1 -C 4  alkyl, C 1 -C 3  alkoxy or trifluoromethyl;     each R 5  is independently selected from halo, C 1 -C 4  alkyl or trifluo-romethyl;     m is 0, 1 or 2; and     n is 0 or 1;    
        each of R 2  and R 3  is independently selected from hydrogen, deuterium or CY 3 ;     each carbon atom is optionally replaced with  13 C; 
 
 wherein at least one Y is deuterium. 
   

      Applicant has discovered that the replacement of one or more hydrogen atoms with deuterium in a compound of formula I results in a compound with different and, in certain compounds, superior properties. These compounds, and compositions comprising them, are useful for treating or lessening the severity of disorders characterized by reduced interstitial concentrations of serotonin or norepinephrine. The compounds and compositions of this invention are also useful as analytical reagents for determining the concentration of the corresponding non-deuterated, non- 13 C compound in solution. The term “corresponding non-deuterated, non- 13 C compound” as used herein refers to a compound wherein all Y are hydrogen and all carbon atoms are  12 C.  
      The exchange of deuterium in place of hydrogen in an organic molecule typically alters its intrinsic physicochemical properties. This is due to the increased mass of deuterium relative to hydrogen and lowered vibrational frequency of molecular bonds involving deuterium relative to those involving hydrogen (Thomton E R, Ann. Rev. Phys. Chem. 1966 17: 349-372; Halevi, E A et. al. J. Chem. Soc. 1963: 866; Cuma M and Scheiner C, J. Phys. Org. Chem. 1997 10: 383). This change is manifested by numerous physical differences, such as chromatographic behavior, hydrophobicity, hydrogen bond strength, and phase transition temperatures. As an example, deuterium oxide (D 2 O, the deuterium analog of water) melts at 3.8° C. in contrast to water, which melts at 0° C., and is more viscous than water. Similarly, hexadeuterated dimethylsulfoxide (DMSO-d 6 ) melts at a higher temperature, but boils at a lower temperature than its non-deuterated analog. Typically, deuterated compounds will elute faster by reverse-phase HPLC than nondeuterated compounds, apparently due to reduced hydrophobic interactions with the column packing, although the physical chemistry leading to this observed difference is complex (Turowski M et. al., J. Am. Chem. Soc. 2003 125: 13836).  
      Incorporation of deuterium in place of hydrogen also has significant effects on the physiological and pharmacological activities of the substituted compound. For instance, N-nitrosamines substituted with deuterium can display increased, decreased, or unchanged carcinogenicity depending on where in the compound hydrogen is replaced with deuterium and on the identity of the compound to which substitutions are made (Lijinsky W et. al. Food Cosmet. Toxicol. 1982 20: 393; Lijinsky W et. al. JCNI 1982 69: 1127). Similarly, both increases and decreases in bacterial mutagenicity of deuterium-substituted aza-amino acids are known, depending on the identity of the amino acid derivative and position of substitution (Mangold J B et. al. Mutation Res. 1994 308: 33). Reduced hepatotoxicity of certain deuterium-substituted compounds is known (Gordon W P et. al. Drug Metab. Dispos.1987 15: 589; Thompson D C et. al. Chem. Biol. Interact. 1996 101: 1). Deuterium substitution can affect the odor of a compound (Turin L, Chem. Senses 1996 21: 773) and plasma protein binding (Echmann M L et. al. J. Pharm. Sci. 1962 51: 66; Cherrah Y. et. al. Biomed. Environm. Mass Spectrom. 1987 14: 653; Cherrah Y. et. al. Biochem. Pharmacol. 1988 37: 1311). Changes in the biodistribution and clearance of certain deuterium and  13 C-substituted compounds suggests changes in their recognition by active transport mechanisms (Zello G A et. al. Metabolism 1994 43: 487; Gately S J et. al. J. Nucl. Med. 1986 27: 388; Wade D, Chem. Biol. Interact. 1999 117: 191).  
      Replacement of hydrogen with deuterium at sites subject to oxidative metabolism by, for instance, heme proteins such as cytochrome P450 and peroxidase enzymes, is known in certain, but not all, cases to produce a significant reduction in the rate of metabolism due to the primary isotope effect of breaking the C— 1 H versus C— 2 H bond (Guengerich F P et. al. J. Biol. Chem. 2002 277: 33711; Kraus, J A and Guengerich, F P, J. Biol. Chem. (Web edition) 2005 280: 19496; Mitchell K H et. al., Proc. Natl. Acad. Sci. USA 2003 109: 3784; Nelson S D and Trager W F, Drug Metab. Dispos. 2003 31: 1481; Hall L R and Hanzlik, R P J. Biol. Chem. 1990 265: 12349; Okazaki O. and Guengerich F P J. Biol. Chem. 268, 1546; Iwamura S et. al. J. Pharmacobio-Dyn. 1987 10: 229). If the C—H bond breaking step is rate-limiting a substantial isotope effect can be observed. If other steps determine the overall rate of reaction, the isotope effect may be insubstantial. In cases where a rate limiting step of a reaction involves rehybridization of the attached carbon from sp2 to sp3, deuterium substitution often creates a negative isotope effect, speeding up the reaction rate.  
      Isotope effects caused by substitution of  13 C for  12 C can also affect the rate of C—H bond cleavage by enzymatic oxidation. It is further believed that  13 C substitution combined with deuterium substitution where the two isotopes are bonded to one another (e.g.  13 C— 2 H) can be of value due to further stabilizing the C—H bond and thus reducing susceptibility to oxidative metabolism.  
       14 C-Labeled Compound A has been described for use in metabolism studies (Wheeler W J and Kuo F, J. Labelled Compd Radiopharm 1995, 36: 213). However the radioactive isotopes  3 H and  14 C are physiologically harmful in significant doses and are not useful in routine medicaments.  
      Although incorporation of stable heavy atoms into specific organic compounds can change their pharmacological properties, general exposure to and incorporation of stable heavy atoms is safe within levels potentially achieved by use of compounds of this invention as medicaments. For instance, the percentages of hydrogen and carbon in a mammal (approximately 9% and 18% by weight, respectively) and natural abundances of deuterium and  13 C (0.015% and 1.11%, respectively) indicate that a 70 kg human normally contains nearly a gram of deuterium and approximately 140 g of  13 C. Furthermore, replacement of up to about 15% of normal hydrogen with deuterium has been effected and maintained for a period of days to weeks in mammals, including rodents and dogs, with minimal observed adverse effects (Czajka D M and Finkel A J, Ann. N.Y. Acad. Sci. 1960 84: 770; Thomson J F, Ann. N.Y. Acad. Sci 1960 84: 736; Czakja D M et. al., Am. J. Physiol. 1961 201: 357). Higher deuterium concentrations, usually in excess of 20%, can be toxic in animals. However, brief replacement of as high as 23% of the hydrogen in humans&#39; fluids with deuterium was found not to cause toxicity (Blagojevic N et. al. in “ Dosimetry &amp; Treatment Planning for Neutron Capture Therapy ”, Zamenhof R, Solares G and Harling O Eds. 1994. Advanced Medical Publishing, Madison Wis. pp.125-134). In a 70 kg human male, 15% replacement of the hydrogen in the fluid compartment with deuterium corresponds to incorporation of approximately 1 kg of deuterium or the equivalent of approximately 5 kg of deuterated water. Replacement of 15% of all of the body&#39;s hydrogen with deuterium, as effected in animal studies, would correspond to about twice that amount of deuterium incorporation. These levels are orders of magnitude beyond the conceived level of administration of any of the deuterium-containing compounds of this invention.  
      Similarly, replacement of up to 60% of the normally abundant  12 C with  13 C has been effected in mice without any observed adverse effects (Gregg C T et. al., Life Sci. 1973 13: 775; Gregg C et. al. in Klein E R and Klein P D (eds.) Proceedings of the Second International conference on Stable Isotopes, US Department of Commerce; Springfield Va., 1975, pp 64-75). Stable isotope tracers, such as  13 C-labeled glucose and repeated doses of hundreds to thousands of milligrams of deuterated water, are used in humans of all ages, including babies and pregnant women, without reported incident (Pons G and Rey E, Pediatrics 1999 104: 633; Coward W A et. al., Lancet 1979 7: 13; Schwarcz H P, Control. Clin. Trials 1984 5(4 Suppl): 573; Rodewald L E et. al., J. Pediatr. 1989 114: 885; Butte N F et. al. Br. J. Nutr. 1991 65: 3). Thus, it is clear that any stable heavy isotope released, for instance, during the metabolism of compounds of this invention poses no health risk.  
      Without being bound by theory, applicant believes that the novel compounds of this invention will demonstrate altered and even unexpectedly superior properties as compared to the corresponding non-deuterated, non- 13 C compounds. Oxidative metabolism, plasma protein binding, hydrophobicity, hydrogen bond strength, polarizability, and phase transition points are each important parameters contributing to the effectiveness or manufacturability of pharmacological agents. It is predicted that one or more of these altered properties will translate into superior biological, chemical and/or pharmacokinetic properties for a compound of this invention as compared to the corresponding non-deuterated, non- 13 C compounds.  
      Such altered properties include, but are not limited to, higher potency, longer biological half life, increased safety profile, enhanced penetration into the CNS, decreased desolvation energy, enhanced receptor binding affinity, increased physicochemical stability, and enhanced shelf life. It is expected that the compounds of this invention will exhibit one or more of such altered and desirable properties.  
      These altered properties will not, however, obliterate the ability of the compounds of this invention to bind to their receptor targets. This is because such receptor binding is primarily dependent upon non-covalent binding between the receptor and the inhibitor, and any negative effects that a heavy atom may have on the highly optimized non-covalent binding between compounds of Formula I and the norepinephrine and serotonin uptake machinery will be minor.  
      Major factors contributing to the noncovalent recognition of small molecules by proteins and the binding strength between them include Van der Waals forces, hydrogen bonds, ionic bonds, molecular reorganization, desolvation energy of the small molecule, hydrophobic interactions, and in certain instances displacement energy for pre-existing bound ligands. See, for instance, Goodman &amp; Gilman&#39;s The Pharmacological Basis of Therapeutics, Tenth Edition, Hardman J G and Limbird L E, eds. McGraw-Hill, 2001.  
      The compounds of this invention possess molecular topology that is very similar to their non-heavy atom substituted analogs of Formula I, since exchange of  13 C for  12 C is conformationally neutral and exchange of deuterium for hydrogen does not alter molecular shape. Deuterium replacement does cause a slight decrease in Van der Waals radius (Holtzer M E et. al., Biophys. J. 2001 80: 939; Wade D, Chem. Biol. Interact. 1999 117: 191), but applicant believes that such decrease will not significantly reduce binding affinity between the molecule and its receptor. Furthermore, the smaller size of the deuterated compounds prevents their being involved in new undesirable steric clashes with the binding protein relative to the unsubstituted compounds. Neither  13 C, nor deuterium, atoms in the compounds of this invention contribute significantly to hydrogen bonding or ionic interactions with the protein receptors. This is because the majority of hydrogen bond and ionic interactions formed by the compound with the receptor are through the amine nitrogen and possibly the ether oxygen. Any deuterium atoms attached to the amine nitrogen will be rapidly exchanged with bulk solvent protons under physiological conditions. Protein reorganization will be identical between a compound of this invention and its corresponding non-deuterated, non- 13 C compounds. As discussed above, desolvation energy of a compound of this invention comprising deuterium is less than that of the corresponding non-deuterated, non- 13 C compound, thus increasing binding affinity for the receptor. Desolvation energy for a compound of this invention comprising  13 C in place of  12 C is essentially identical.  
      Thus, a compound of this invention advantageously retains substantial binding to the serotonin and norepinephrine uptake proteins and is an active inhibitor of serotonin and norepinephrine uptake.

Each of these documents is incorporated herein by reference. Additional synthetic approaches and protocols can readily be discerned by the skilled artesian, for instance with the assistance of commercial structure-searchable chemical compound and reaction databases such as SciFinder (CAS Division of the American Chemical Society) and CrossFire Beilstein (Elsevier MDL®).  
                 
 
      In Scheme I, each Y is independently selected from hydrogen or deuterium and each carbon atom is optionally replaced with  13 C. Bases include strong deprotonating agents known in the art of organic synthesis and preferably those comprising alkali metal bases such as sodium, potassium and lithium. Potassium hydride and especially sodium hydride are more preferred bases.  
      In addition to the examples set forth below, many additional  13 C-containing starting materials are available and can be incorporated into compounds of this invention by means known to those of skill in the art of organic synthesis. For instance, vendors such as Aldrich Chemicals and their subsidiary Isotec (Miamisburg, Ohio), Cambridge Isotope Laboratories (Andover, Mass.), Icon Isotopes (Summit, N.J.); C/D/N Isotopes (Pointe-Claire, Quebec) and Medical Isotopes Inc. (Pelham, N.H.), among others, routinely stock a wide array of  13 C-labeled reagents, in many cases co-labeled with other stable isotopes such as deuterium. Intermediates and final compounds of this invention including  13 C can be made with no or only slight modification to routes useful for the  12 C isotopologues. Any optimization for a particular  13 C-labeled compound is within the ability of the ordinarily skilled synthetic chemist. Synthetic routes to  13 C-labeled compounds useful as starting materials or intermediates to compounds of formula I are also available in commercial databases such as SciFinder (CAS Division of the American Chemical Society) or can be readily designed based on routes known for  12 C isotopologues. Thus, the skilled artesian has the means to design and synthesize singly and multiply- 13 C-labeled compounds of this invention.  
      In cases where incorporation of stable heavy atom isotopes in the N-methyl position is desired, it can be advantageous to use a modification of this process, shown herein as Scheme II. According to this method, a suitably protected mono-N-methyl analog of Formula XXVII, wherein Q is a removable protecting group, is prepared and then reacted with an appropriate naphthalene derivative XXV. N-Deprotection then yields the desired compound of Formula XXIII. Particularly useful N-protecting groups are alkyl derivatives, including benzyl derivatives such as benzyl, p-methoxybenzyl, 2,4-dimethoxybenzyl, trityl, 5′-dibenzosuberyl  
                 
 
 and the like. Other useful protecting groups will be apparent to those of skill in the art.  
                 
 
      Compounds of Formulae XXIV and XXVII may be advantageously be derived by asymmetric chiral reduction of a precursor ketone, itself derived from addition of thiophene-2-anion to an acyl derivative such as an N,O-dimethylhydroxylamine amide or imidazole amide. See Ohkuma T et. al. Org. Lett. 2000 2: 1749. Other methods will be apparent to those of ordinary skill in synthetic chemistry.  
                 
 
      A particularly useful approach to making compounds of Formula XXVII is shown in Scheme III. In this scheme, compounds of Formula XXIX (wherein each Y is independently hydrogen or deuterium) are precursors incorporating, as appropriate, a removable nitrogen protecting group Q such as are known in the art. Scheme III may alternately be used to produce a compound of Formula XXIV if Q on a compound of Formula XXIX is replaced with a C(Y 16a ) (Y 16b ) (Y 16c ) group, wherein each of Y 16a , Y 16b , Y 16c , is independently hydrogen or deuterium.  
      Another embodiment is a compound of any of the formulae herein made by a process delineated herein, including the processes exemplified in the schemes and examples herein. The chemicals used in the synthetic routes described herein may include, for example, solvents, reagents, catalysts, and protecting group and deprotecting group reagents. The methods described herein may also additionally include steps, either before or after the steps described specifically herein, to add or remove suitable protecting groups in order to ultimately allow synthesis of the compounds herein. In addition, various synthetic steps may be performed in an alternate sequence or order to give the desired compounds. Synthetic chemistry transformations and protecting group methodologies (protection and deprotection) useful in synthesizing the applicable compounds are known in the art and include, for example, those described in R. Larock,  Comprehensive Organic Transformations , VCH Publishers (1989); T. W. Greene and P. G. M. Wuts,  Protective Groups in Organic Synthesis,  3R d  Ed., John Wiley and Sons (1999); L. Fieser and M. Fieser,  Fieser and Fieser&#39;s Reagents for Organic Synthesis , John Wiley and Sons (1994); and L. Paquette, ed.,  Encyclopedia of Reagents for Organic Synthesis , John Wiley and Sons (1995) and subsequent editions thereof.  
      The methods described herein may also additionally include steps, either before or after the steps described specifically herein, to add or remove suitable protecting groups in order to ultimately allow synthesis of the compound of the formulae described herein. The methods delineated herein contemplate converting compounds of one formula to compounds of another formula. The process of converting refers to one or more chemical transformations, which can be performed in situ, or with isolation of intermediate compounds. The transformations can include reacting the starting compounds or intermediates with additional reagents using techniques and protocols known in the art, including those in the references cited herein. Intermediates can be used with or without purification (e.g., filtration, distillation, crystallization, chromatography).  
      According to another embodiment, the invention provides a compound of above-described formula XXVIII, wherein at least one Y is deuterium.  
      According to another embodiment, the invention provides a compound of above-described formula XXV, wherein from one to six Y moieties are deuterium and wherein any carbon atom is optionally replaced with a  13 C atom. Preferably, at least one of Y 3 , Y 4 , Y 5  and Y 6  are deuterium.

      According to another embodiment, the invention provides a compound of above-described formula XXVII, wherein at least one Y is deuterium.  
      Combinations of substituents and variables envisioned by this invention are only those that result in the formation of stable compounds. The term “stable”, as used herein, refers to compounds which possess stability sufficient to allow manufacture and which maintain the integrity of the compound for a sufficient period of time to be useful for the purposes detailed herein (e.g., formulation into therapeutic products, intermediates for use in production of therapeutic compounds, isolatable or storable intermediate compounds, treating a disease or condition characterized by decreased levels of serotonin or norepinepherine).  
      The compounds of this invention include the compounds themselves, or a prodrug thereof; or a pharmaceutically acceptable salt of said compound or prodrug; or a solvate, hydrate, and/or polymorph of said compound, salt, prodrug or prodrug salt, if applicable. As used herein, the term “pharmaceutically acceptable salt,” is a salt formed from, for example, an acid and a basic group of a compound of any one of the formulae disclosed herein. Acids commonly employed to form such salts include inorganic acids such as hydrochloric, hydrobromic, hydroiodic, sulfuric and phosphoric acid, as well as organic acids such as para-to 1 uenesulfonic, methanesulfonic, oxalic, para-bromophenylsulfonic carbonic, succinic, citric, benzoic and acetic acid, and related inorganic and organic acids. Such pharmaceutically acceptable salts thus include sulfate, pyrosulfate, bisulfate, sulfite, bisulfite, phosphate, monohydrogenphosphate, dihydrogenphosphate, metaphosphate, pyrophosphate, chloride, bromide, iodide, acetate, propionate, decanoate, caprylate, acrylate, formate, isobutyrate, caprate, heptanoate, propiolate, oxalate, malonate, succinate, suberate, sebacate, fumarate, maleate, butyne-1,4-dioate, hexyne-1,6-dioate, benzoate, chlorobenzoate, methylbenzoate, dinitrobenzoate, hydroxybenzoate, methoxybenzoate, phthalate, terephathalate, sulfonate, xylenesulfonate, phenylacetate, phenylpropionate, phenylbutyrate, citrate, lactate, β-hydroxybutyrate, glycolate, maleate, tartrate, methanesulfonate, propanesulfonate, naphthalene-1-sulfonate, naphthalene-2-sulfonate, mandelate and the like salts. Preferred pharmaceutically acceptable acid addition salts include those formed with mineral acids such as hydrochloric acid and hydrobromlc acid, and especially those formed with organic acids such as maleic acid.  
      As used herein, the term “hydrate” means a compound of the present invention or a salt thereof, which further includes a stoichiometric or non-stoichiometric amount of water bound by non-covalent intermolecular forces.  
      The term “solvate” means a compound of the present invention or a salt thereof, which further includes a stoichiometric or non-stoichiometric amount of solvent such as water, acetone, ethanol, methanol, dichloromethane, 2-propanol, or the like, bound by non-covalent intermolecular forces.  
      As used herein, the term “polymorph” means solid crystalline forms of a compound of the present invention or complex thereof. Different polymorphs of the same compound can exhibit different physical, chemical and/or spectroscopic properties. Different physical properties include, but are not limited to stability (e.g., to heat or light), compressibility and density (important in formulation and product manufacturing), solubility, and dissolution rates (which can affect bioavailability). Differences in stability can result from changes in chemical reactivity (e.g., differential oxidation, such that a dosage form discolors more rapidly when comprised of one polymorph than when comprised of another polymorph) or mechanical characteristics (e.g., tablets crumble on storage as a kinetically favored polymorph converts to thermodynamically more stable polymorph) or both (e.g., tablets of one polymorph are more susceptible to breakdown at high humidity). Different physical properties of polymorphs can affect their processing. For example, one polymorph might be more likely to form solvates or might be more difficult to filter or wash free of impurities than another due to, for example, the shape or size distribution of particles of it.  
      As used herein and unless otherwise indicated, the term “prodrug” means a derivative of a compound that can hydrolyze, oxidize, or otherwise react under biological conditions (in vitro or in vivo) to provide a compound of this invention. Prodrugs may only become active upon such reaction under biological conditions, or they may have activity in their unreacted forms. Examples of prodrugs contemplated in this invention include, but are not limited to, analogs or derivatives of compounds of any one of the formulae disclosed herein that comprise biohydrolyzable moieties such as biohydrolyzable amides, biohydrolyzable esters, biohydrolyzable carbamates, biohydrolyzable carbonates, biohydrolyzable ureides, and biohydrolyzable phosphate analogues. Other examples of prodrugs include derivatives of compounds of any one of the formulae disclosed herein that comprise —NO, —NO 2 , —ONO, or —ONO 2  moieties. Prodrugs can typically be prepared using well-known methods, such as those described by Burger&#39;s Medicinal Chemistry and Drug Discovery (1995) 172-178, 949-982 (Manfred E. Wolff ed., 5th ed); see also Goodman and Gilman&#39;s, The Pharmacological basis of Therapeutics, 8th ed., McGraw-Hill, Int. Ed. 1992, “Biotransformation of Drugs”.  
      As used herein and unless otherwise indicated, the terms “biohydrolyzable amide”, “biohydrolyzable ester”, “biohydrolyzable carbamate”, “biohydrolyzable carbonate”, “biohydrolyzable ureide” and “biohydrolyzable phosphate analogue” mean an amide, ester, carbamate, carbonate, ureide, or phosphate analogue, respectively, that either: 1) does not destroy the biological activity of the compound and confers upon that compound advantageous properties in vivo, such as uptake, duration of action, or onset of action; or 2) is itself biologically inactive but is converted in vivo to a biologically active compound. Examples of biohydrolyzable amides include, but are not limited to, lower alkyl amides, α-amino acid amides, alkoxyacyl amides, and alkylaminoalkylcarbonyl amides. Examples of biohydrolyzable esters include, but are not limited to, lower alkyl esters, alkoxyacyloxy esters, alkyl acylamino alkyl esters, and choline esters. Examples of biohydrolyzable carbamates include, but are not limited to, lower alkylamines, substituted ethylenediamines, aminoacids, hydroxyalkylamines, heterocyclic and heteroaromatic amines, and polyether amines.  
      The term “isotopologue” refers to a species that differs from a compound of this invention only in the isotopic composition of its molecules or ions. The term “lighter isotopologue,” as used herein, refers to species that differs from a compound of this invention in that it comprises one or more of the light isotopic atoms  1 H or  12 C at positions occupied by a deuterium or  13 C. For the purposes of this invention,  11 C is not referred to as a light isotope of carbon.  
      It will be readily apparent that all lighter isotopologues except the compound devoid of deuterium and  13 C (i.e., the corresponding non-deuterated, non- 13 C compound) are compounds according to this invention. Thus, for example, a compound of formula II, wherein Y 2 , Y 3  and Y 4  are each deuterium has lighter isotopologues wherein Y 2  and Y 3  are deuterium and Y 4  is hydrogen; Y 2  and Y 4  are deuterium and Y 3  is hydrogen; Y 3  and Y 4  are deuterium and Y 2  is hydrogen; Y 2  is deuterium and Y 3  and Y 4  are hydrogen; Y 3  is deuterium and Y 2  and Y 4  are hydrogen; Y 4  is deuterium and Y 2  and Y 3  are hydrogen; and Y 2 , Y 3  and Y 4  are all hydrogen, this latter compound being the corresponding non-deuterated, non- 13 C compound.  
      Chemical naming terminology can be complex and different chemical names can often reasonably be applied to the same structure. To avoid any confusion, “Compound A” refers to the chemical structure shown herein for that compound.  
      It will be recognized that many commonly occurring atoms in biological systems exist naturally as mixtures of isotopes. Thus, any macroscopic amount of Compound 1, although designated in its formula as being devoid of deuterium and  13 C, when synthesized inherently contains small amounts of deuterated and  13 C-containing isotopologues. The present invention excludes such minor amounts of said isotopologues (“variant isotopologues”) from its scope in that the term “compound” as used in this invention refers to a composition of matter that is predominantly the specific carbon and hydrogen isotopologue designated by its formula. A compound, as defined herein, in embodiments contains less than 10%, preferably less than 6%, and more preferably less than 3% of all other carbon and hydrogen isotopologues, including Compound 1, as variant isotopologues. Compositions of matter that contain greater than 10% of all other specific carbon and hydrogen isotopologues combined are referred to herein as mixtures and must meet the parameters set forth below. These limits of isotopic composition, and all references to isotopic composition herein, refer solely to the carbons and hydrogens of the compound of Formula I and do not include the isotopic composition of other atom types, for instance solvent entrapped as a solvate or excipients used in formulating compounds of this invention.  
      The term “heavy atom” refers to isotopes of higher atomic weight than the predominant naturally occurring isotope.  
      The term “stable heavy atom” refers to non-radioactive heavy atoms.

      The invention further provides a mixture of a compound of this invention and its lighter isotopologues. These mixtures may occur, for instance, simply as the result of an inefficiency of incorporating the isotope at a given position; intentional or inadvertent exchange of protons for deuterium, e.g. exchange of bulk solvent for heteroatom-attached deuterium; or intentional mixtures of pure compounds.  
      In one embodiment, such mixtures comprise at least about 50% of the full isotopic compound (i.e., less than about 50% of lighter isotopologues). More preferable is a mixture comprising at least 80% of the full isotopic compound. Even more preferable is a mixture comprising at least 90% of the full isotopic compound. Even more preferable is a mixture comprising at least 95% of the full isotopic compound. Most preferred is a mixture comprising at least 98% of the full isotopic compound.  
      In an alternate embodiment the mixture comprises a compound and its lighter isotopologues in relative proportions such that at least about 50%, preferably at least 80%, more preferably at least 90%, even more preferably at least 95% and most preferably at least 98% of the compounds in said mixture comprise an isotope at each position containing an isotope in the full isotopic compound. The following exemplifies this definition. A hypothetical compound of the invention contains deuterium at positions Y 2 , Y 3  and Y 4 . A mixture comprising this compound and all of its potential lighter isotopologues and the relative proportion of each is set forth in the table below.  
                                   TABLE 14                                               Relative           Y 2     Y 3     Y 4     Amt                                                        Compound   D   D   D   40%       Isotopologue 1   D   D   H   15%       Isotopologue 2   D   H   D   15%       Isotopologue 3   H   D   D   15%       Isotopologue 4   D   H   H    4%       Isotopologue 5   H   D   H    4%       Isotopologue 6   H   H   D    4%       Isotopologue 7   H   H   H    3%       % of   (40% + 15% + 15% + 4%) =   74%   74%   74%       compounds       comprising an       isotope at       position Y 2                    
 
      From the table it can be seen that the compound plus lighter isotopologues 1, 2 and 4 comprises the isotope deuterium at position Y 2 . These compounds are present in the mixture at relevant amounts of 40%, 15%, 15% and 4%. Thus, 74% of the mixture comprises the isotope at Y 2  that is present in the compound.  
      The invention also provides compositions comprising an effective amount of a compound of Formula I (e.g., including any of the formulae herein), or a prodrug thereof; or a pharmaceutically acceptable salt of said compound or prodrug; or a solvate, hydrate, and/or polymorph of said compound, salt, prodrug or prodrug salt, if applicable; and an acceptable carrier. Preferably, a composition of this invention is formulated for pharmaceutical use (“a pharmaceutical composition”), wherein the carrier is a pharmaceutically acceptable carrier. The carrier(s) must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and, in the case of a pharmaceutically acceptable carrier, not deleterious to the recipient thereof in amounts typically used in medicaments.  
      Pharmaceutically acceptable carriers, adjuvants and vehicles that may be used in the pharmaceutical compositions of this invention include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, polyethylene glycol and wool fat.  
      The pharmaceutical compositions of the invention include those suitable for oral, rectal, nasal, topical (including buccal and sublingual), vaginal or parenteral (including subcutaneous, intramuscular, intravenous and intradermal) administration. In certain embodiments, the compound of the formulae herein is administered transdermally (e.g., using a transdermal patch or iontophoretic techniques). Other formulations may conveniently be presented in unit dosage form, e.g., tablets and sustained release capsules, and in liposomes, and may be prepared by any methods well known in the art of pharmacy. See, for example, Remington&#39;s Pharmaceutical Sciences, Mack Publishing Company, Philadelphia, Pa. (17th ed. 1985).  
      Such preparative methods include the step of bringing into association with the molecule to be administered ingredients such as the carrier that constitutes one or more accessory ingredients. In general, the compositions are prepared by uniformly and intimately bringing into association the active ingredients with liquid carriers, liposomes or finely divided solid carriers or both, and then if necessary shaping the product.  
      In certain preferred embodiments, the compound is administered orally. Compositions of the present invention suitable for oral administration may be presented as discrete units such as capsules, sachets or tablets each containing a predetermined amount of the active ingredient; as a powder or granules; as a solution or a suspension in an aqueous liquid or a non-aqueous liquid; or as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion, or packed in liposomes and as a bolus, etc.  
      A tablet may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as a powder or granules, optionally mixed with a binder, lubricant, inert diluent, preservative, surface-active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent. The tablets optionally may be coated or scored and may be formulated so as to provide slow or controlled release of the active ingredient therein. Methods of formulating such slow or controlled release compositions of pharmaceutically active ingredients, such as those herein and other compounds known in the art, are known in the art and described in several issued US Patents, some of which include, but are not limited to, U.S. Pat. Nos. 4,369,172; and 4,842,866, and references cited therein. Coatings can be used for delivery of compounds to the intestine (see, e.g., U.S. Pat. Nos. 6,638,534, 5,217,720, and 6,569,457, 6,461,631, 6,528,080, 6,800,663, and references cited therein). A useful formulation for the compounds of this invention is the form of enteric pellets of which the enteric layer comprises hydroxypropylmethylcellulose acetate succinate. Formulation of this type has been shown to be useful for Compound A. See Anderson N R et. al., U.S. Pat. No. 5,508,276, incorporated herein by reference.  
      In the case of tablets for oral use, carriers that are commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried cornstarch. When aqueous suspensions are administered orally, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening and/or flavoring and/or coloring agents may be added.  
      Compositions suitable for topical administration include lozenges comprising the ingredients in a flavored basis, usually sucrose and acacia or tragacanth; and pastilles comprising the active ingredient in an inert basis such as gelatin and glycerin, or sucrose and acacia.  
      Compositions suitable for parenteral administration include aqueous and non-aqueous sterile injection solutions which may contain anti-oxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which may include suspending agents and thickening agents. The formulations may be presented in unit-dose or multi-dose containers, for example, sealed ampules and vials, and may be stored in a freeze dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example water for injections, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets.  
      Such injection solutions may be in the form, for example, of a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to techniques known in the art using suitable dispersing or wetting agents (such as, for example, Tween 80) and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are mannitol, water, Ringer&#39;s solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil may be employed including synthetic mono- or diglycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain ethanol or a longer-chain alcohol diluent or dispersant.  
      The pharmaceutical compositions of this invention may be administered in the form of suppositories for rectal administration. These compositions can be prepared by mixing a compound of this invention with a suitable non-irritating excipient which is solid at room temperature but liquid at the rectal temperature and therefore will melt in the rectum to release the active components. Such materials include, but are not limited to, cocoa butter, beeswax and polyethylene glycols.  
      Topical administration of the pharmaceutical compositions of this invention is especially useful when the desired treatment involves areas or organs readily accessible by topical application. For application topically to the skin, the pharmaceutical composition should be formulated with a suitable ointment containing the active components suspended or dissolved in a carrier. Carriers for topical administration of the compounds of this invention include, but are not limited to, mineral oil, liquid petroleum, white petroleum, propylene glycol, polyoxyethylene polyoxypropylene compound, emulsifying wax and water. Alternatively, the pharmaceutical composition can be formulated with a suitable lotion or cream containing the active compound suspended or dissolved in a carrier. Suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol and water.

      In another embodiment, the invention provides separate dosage forms of a compound of this invention and a second therapeutic agent that are associated with one another. The term “associated with one another” as used herein means that the separate dosage forms are packaged together or otherwise attached to one another such that it is readily apparent that the separate dosage forms are intended to be sold and administered together (within less than 24 hours of one another, consecutively or simultaneously).  
      In the pharmaceutical compositions of the invention, the compound of the present invention is present in an effective amount. As used herein, the term “effective amount” refers to an amount which, when administered in a proper dosing regimen, is sufficient to reduce or ameliorate the severity, duration or progression of a disorder characterized by reduced interstitial concentrations of serotonin or epinephrine, prevent the advancement of a disorder characterized by reduced interstitial concentrations of serotonin or epinephrine, cause the regression of a disorder characterized by reduced interstitial concentrations of serotonin or epinephrine, or enhance or improve the prophylactic or therapeutic effect(s) of another therapy. In certain preferred embodiments, treatment according to the invention provides a reduction in or prevention of at least one symptom or manifestation of a disorder that has been linked to reduced neurotransmission of serotonin or epinephrine, as determined in vivo or in vitro of at least about 10%, more preferably 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 98% or 99%. With respect to inhibition of serotonin or norepinephrine reuptake, the term “effective amount” means an amount that results in a detectable increase in the amount or concentration of serotonin or norepinephrine in a patient or in a biological sample, the correction of or relief from a behavior, deficit, symptom, syndrome or disease that has been linked to reduced neurotransmission of serotonin or epinephrine, alone or in combination with another agent or agents; or the induction of a behavior, activity or response that has been linked to normalized or increased neurotransmission of serotonin or epinephrine.  
      The interrelationship of dosages for animals and humans (based on milligrams per meter squared of body surface) is described in Freireich et al., (1966) Cancer Chemother Rep 50: 219. Body surface area may be approximately determined from height and weight of the patient. See, e.g., Scientific Tables, Geigy Pharmaceuticals, Ardley, N.Y., 1970, 537. An effective amount of a compound of this invention can range from about 0.001 mg/kg to about 500 mg/kg, more preferably 0.01 mg/kg to about 50 mg/kg, more preferably 0.1 mg/kg to about 2.5 mg/kg. Effective doses will also vary, as recognized by those skilled in the art, depending on the diseases treated, the severity of the disease, the route of administration, the sex, age and general health condition of the patient, excipient usage, the possibility of co-usage with other therapeutic treatments such as use of other agents and the judgment of the treating physician.  
      For pharmaceutical compositions that comprise additional therapeutic agents, an effective amount of the other agent is between about 20% and 100% of the dosage normally utilized in a monotherapy regime using just that additional agent. Preferably, an effective amount is between about 70% and 100% of the normal monotherapeutic dose. The normal monotherapuetic dosages of these additional therapeutic agents are well known in the art. See, e.g., Wells et al., eds., Pharmacotherapy Handbook, 2nd Edition, Appleton and Lange, Stamford, Conn. (2000); PDR Pharmacopoeia, Tarascon Pocket Pharmacopoeia 2000, Deluxe Edition, Tarascon Publishing, Loma Linda, Calif. (2000), each of which references are entirely incorporated herein by reference.  
      It is expected that some of the additional therapeutic agents listed above will act synergistically with the compounds of this invention. When this occurs, its will allow the effective dosage of the additional therapeutic agent and/or the compound of this invention to be reduced from that required in a monotherapy. This has the advantage of minimizing toxic side effects of either the additional therapeutic agent of a compound of this invention, synergistic improvements in efficacy, improved ease of administration or use and/or reduced overall expense of compound preparation or formulation.  
      Methods of Treatment  
      In one embodiment, the present invention provides a method of inhibiting the reuptake of serotonin and norepinephrine in a subject comprising the step of administering to said subject an effective amount of a compound of this invention. Another embodiment of the invention is a method of treating a subject suffering from or susceptible to depression; pain, particularly diabetic neuropathy pain; attention-deficit/hyperactivity disorder; fibromyalgia; psoriasis; interstitial cystitis; or incontinence, said method comprising the step of administering to said subject an effective amount of a compound of this invention. Other embodiments include any of the methods herein wherein the subject is identified as in need of the indicated treatment.  
      In another embodiment, the method of treatment further comprises the step of administering to said patient another therapeutic agent conventionally used to treat or prevent depression, obsessive-compulsive disease, aggressive disorder, premature ejaculation, cardiovascular disease, urinary tract disorders, psychosis, acute mania, anxiety, pain, sleep disorders, for reducing associated gastrointestinal side-effects of serotonin reuptake inhibitors, or for potentiating drug activity.  
      The additional therapeutic agent may be administered together with a compound of this invention as part of a single dosage form or as multiple dosage forms. Alternatively, the additional agent may be administered prior to, consecutively with, or following the administration of a compound of this invention. In such combination therapy treatment, both the compounds of this invention and the other therapeutic agent(s) are administered by conventional methods. The administering of the other therapeutic agent may occur before, concurrently with, and/or after the administering of the compound of this invention. When the administering of the other therapeutic agent occurs concurrently with a compound of this invention, the two (or more) agents may be administered in a single dosage form (such as a composition of this invention comprising a compound of the invention and an additional therapeutic agent as described above), or in separate dosage forms. The administration of a composition of this invention comprising both a compound of the invention and an additional therapeutic agent to a subject does not preclude the separate administration of said therapeutic agent, any other therapeutic agent or any compound of this invention to said subject at another time during a course of treatment.  
      Effective amounts of the other therapeutic agents are well known to those skilled in the art and guidance for dosing may be found in patents referenced herein, as well as in Wells et al., eds., Pharmacotherapy Handbook, 2nd Edition, Appleton and Lange, Stamford, Conn. (2000); PDR Pharmacopoeia, Tarascon Pocket Pharmacopoeia 2000, Deluxe Edition, Tarascon Publishing, Loma Linda, Calif. (2000), and other medical texts. However, it is well within the skilled artisan&#39;s purview to determine the other therapeutic agent&#39;s optimal effective-amount range. In one embodiment of the invention where another therapeutic agent is administered to an animal, the effective amount of the compound of this invention is less than its effective amount would be where the other therapeutic agent is not administered. In another embodiment, the effective amount of the conventional agent is less than its effective amount would be where the compound of this invention is not administered. In this way, undesired side effects associated with high doses of either agent may be minimized. Other potential advantages (including without limitation improved dosing regimens and/or reduced drug cost) will be apparent to those of skill in the art.  
      Additional therapeutic agents useful in the method of treatment are the same as those described above as part of combination compositions.  
      Animal models measuring the uptake of serotonin and norepinephrine have proven useful to predicting the human utility of Compound A and related compounds; see: Robertson D W et. al. U.S. Pat. No. 4,956,388 to Lilly. Similarly, the activity of Compound A in animal models of pain accurately presaged its activity in human pain and sensory disorders: Goldstein D J et. al. U.S. Pat. No. 6,596,756 to Lilly. Each of the compounds of this invention may be tested in such animal models. The compounds of the invention may also be tested in in vitro assays, to quantitate their activity, resistance to liver metabolism compared to the corresponding non-deuterated, non- 13 C compound and therapeutic usefulness.  
      Diagnostic Methods and Kits  
      According to another embodiment, the invention provides a method of determining the concentration of a first compound having the formula:  
                 
 
 in a biological sample, wherein: 
      R 1  is selected from C 5 -C 7  cycloalkyl, thienyl, halothienyl, (C 1 -C 4  alkyl) thienyl, furanyl, pyridyl, or thiazolyl;     Ar is  
                 
        each R 4  is independently selected from halo, C 1 -C 4  alkyl, C 1 -C 3  alkoxy or trifluoromethyl;     each R 5  is independently selected from halo, C 1 -C 4  alkyl or trifluo-romethyl;     m is 0, 1 or 2; and     n is 0 or 1; and    
        each of R 2a  and R 3a  is independently selected from hydrogen or CH 3 ; said method comprising the steps of:     a) adding a known concentration of a second compound to said biological sample, said second compound having the formula:  
                 
 
 or an acid addition salt thereof, to said biological sample, wherein: 
    each Y is independently selected from H or deuterium;     Ar is  
                 
    R 1  is the same as R 1  in said first compound;     each of R 2  and R 3  is independently selected from: 
        i) hydrogen or deuterium if the corresponding R 2a  or R 3a  is hydrogen in said first compound, or     ii) CY 3  if the corresponding R 2a  or R 3a  is in said first compound is methyl;    
        each carbon atom in said second compound optionally replaced with  13 C, wherein at least one Y is deuterium or at least one carbon is replaced with  13 C;     b) subjecting said biological sample to a measuring device that distinguishes said first compound from said second compound;     c) calibrating said measuring device to correlate the detected quantity of said second compound with the known concentration of said second compound added to said biological sample; and     d) determining the concentration of said first compound in said biological sample by comparing the detected quantity of said first compound with the detected quantity and known concentration of said second compound.    

      Measuring devices that can distinguish said first compound from said second compound include any measuring device that can distinguish between first compound and a second compound that is of identical structure except that it contains one or more deuterium in place of one or more hydrogen, or one or more  13 C in place of one or more  12 C. Preferably, such a measuring device is a mass spectrometer.  
      In a preferred embodiment, the sum of Y moieties that are deuterium and carbon atoms that are replaced by  13 C in said second compound is three or greater.  
      In another preferred embodiment, the method comprises the additional step of organically extracting said first and said second compounds from said biological sample prior to step b).  
      The first and the second compounds will have similar solubility, extraction, and chromatographic properties, but significantly different molecular mass. Thus, the second compound is useful as an internal standard in a method that comprises the step of organic extraction to measure the efficiency of that extraction and to ensure an accurate determination of the true concentration or the first compound (see Tuchman M and McCann M T, Clin. Chem. 1999 45: 571; Leis H J et. al., J. Mass Spectrom. 2001 36: 923; Taylor R L et. al. Clin. Chem. 2002 48: 1511, the disclosures of which are herein incorporated by reference).  
      The compounds of the present invention (the second compound) are particularly useful in this method since they are not radioactive and therefore do not pose a hazard to personnel handling the compounds. Thus, these methods do not require precautions beyond those normally applied in clinical sample analysis. Furthermore, stably labeled isotopes have long been used to assisting in research into the enzymatic mechanism of cytochrome P450 enzymes (Korzekwa K R et. al., Drug Metab. Rev. 1995 27: 45; Kraus, J A and Guengerich, F P, J. Biol. Chem. 2005 280: 19496; Mitchell K H et. al., Proc. Natl. Acad. Sci. USA 2003 109: 3784).  
      In a related embodiment, the invention provides a diagnostic kit comprising a diagnostic compound having the formula:  
                 
 
 or a pharmaceutically acceptable acid addition salt thereof, as described above, in a sealed vessel, wherein R 1 , R 2 , R 3 , Y and Ar are as defined for a compound of formula I, above; and instructions for using said compound to determine the concentration of a test compound in a biological sample. In a preferred embodiment, the sum of Y moieties that are deuterium and carbon atoms that are replaced by  13 C in said diagnostic compound is three or greater. 
 
      In another embodiment, the invention provides a method of evaluating the metabolic stability of a compound of formula I, comprising the steps of contacting the compound of formula I or its acid addition salt with a metabolizing enzyme source for a period of time; and comparing the amount of said compound and metabolic products of said compounds after said period of time.  
      In one preferred embodiment, the method comprises an additional step of comparing the amount of said compound and said metabolic products of said compounds at an interval during said period of time. This method allows the determination of a rate of metabolism of said compound.  
      In another preferred embodiment, the method comprises the additional steps of contacting an isotopologue of said compound with said metabolizing enzyme source; comparing the amount of said isotopologue and metabolic products of said isotopologue after said period of time determining a rate of metabolism of said isotopologue; and comparing the metabolic stability of said compound and said isotopologue. This method is useful in determining at which sites on the compound a deuterium or  13 C would cause the greatest increase in metabolic stability. It is also useful in determining if a compound is more metabolically stable than its corresponding non-deuterated, non- 13 C compound.  
      A metabolizing enzyme source may be a purified, isolated or partially purified metabolic protein, such as a cytochrome P450; a biological fraction, such as a liver microsome fraction; or a piece of a metabolizing organ, such as a liver slice.  
      The determination of the amount of compound and its metabolic products is well known in the art. It is typically achieved by removing an aliquot from the reaction mixture and subjecting it to an analysis capable of distinguishing between the compound and its metabolites, such as reversed-phase HPLC with UV absorption or mass spectroscopic detection. Concentrations of both the metabolizing enzyme and the compound may be varied to determine kinetic parameters, for instance, by using appropriate nonlinear regression software such as is known in the art. By comparing the kinetic parameters of both a compound and the corresponding non-deuterated, non- 13 C isotopologue an apparent steady-state deuterium isotope effect ( D (V/K)) can be determined as the ratio of products formed in the hydrogen versus deuterium reactions.  
      The determination of a rate of metabolism of an isotopologue may be achieved in a reaction separate from the reaction for determining the metabolism rate of the compound. Alternatively, the compound be admixed with an isotopologue in a competition experiment to determine rates of disappearance of the two compounds, making use of analytical instrumentation capable of differentiating between the two compounds based on their mass differences.  
      In yet another embodiment, pre-steady state kinetics, such as V 0 , may be determined by means known in the art, for instance, using quench-flow apparatus, by monitoring the quenched reactions at varying times after mixing the compound or isotopologue with the metabolizing enzyme source.  
      In a related embodiment, the invention provides a kit comprising, in separate vessels: 
      a) a compound of the formula:  
                 
    R 1  is C 5 -C 7  cycloalkyl, thienyl, halothienyl, (C 1 -C 4  alkyl) thienyl, furanyl, pyridyl or thiazolyl;     Ar is  
                 
    each of R 2  and R 3  independently is hydrogen or methyl;     each R 4  independently is halo, C 1 -C 4  alkyl, C 1 -C 3  alkoxy or trifluoromethyl;     each R 5  independently is halo, C 1 -C 4  alkyl or trifluoromethyl;     m is 0, 1 or 2; n is 0 or 1; and     b) a metabolizing enzyme source. The kit is useful for comparing the metabolic stability of a compound of formula I with the corresponding non-deuterated, non- 13 C compound, as well as evaluating the affect of deuterium and  13 C replacement at various positions on a compound of Formula I. In a preferred embodiment, the kit further comprises instructions for using said compound and said metabolizing enzyme source to evaluate the metabolic stability of a compound of formula I.    

      In order that the invention might be more fully understood, the following examples are set forth. They are not intended to limit the scope of the invention and further examples will be evident to those of ordinary skill in the art.  
     EXAMPLE 1  
      1-Fluoro-2,3,4,5,6,7,8-heptadeuteronaphthalene. Two synthetic methods are described.  
      Method A: Cool a solution of 1-naphthol-d 7  (available from Isotec, Miamisburg Ohio, or by the method of Guthrie R D and Shi B, J. Am. Chem. Soc. 1990 112: 3136) (4.0 mmol) in 60 mL of toluene, cooled in an ice/water bath, and treat dropwise over about 1 min with 4.2 mmol of phosgene, followed by dropwise addition during about 1 min 4.2 mmol of N,N-dimethylaniline. After about 10 min, add about 0.5 mL of water dropwise carefully during about 1 min. Dilute the mixture with about 10 mL of toluene and wash sequentially with water, 0.1 N HCl, 0.1 N NaOH, and saturated brine, then dry over anhydrous magnesium sulfate and evaporated to yield an oily residue. Kugelrohr distill to yield naphthyl-1-chloroformate-d 7 .  
      Add anhydrous potassium fluoride (5 mol) to a stirred solution of naphthyl-1-chloroformate-d 7  (3.5 mol) and 18-crown-6 (0.17 mol) in 3 mL of dichloromethane (250 mL) at room temperature. After 5 h, filter the suspension, and evaporate the resulting solution under reduced pressure and purify the resulting oil by vacuum distillation to yield naphthyl-1-fluoroformate-d 7 .  
      Stir a mixture of anhydrous SbF 5  (spatula tip amount, ˜0.5-1 mg) and naphthyl-1-fluoroformate-d 7  (2.5 mol), then heat to about 190° C., where evolution of carbon dioxide commences.
