Title: Hydroxylated nebivolol metabolites

Description:
This application claims priority under 35 USC §119 to U.S. Provisional Application No. 60/648,551, filed Jan. 31, 2005 and to U.S. Provisional Application No. 60/755,856, filed Jan. 3, 2006. 
    
    
     FIELD OF THE INVENTION 
     Metabolites of nebivolol possess pharmacological properties that may be beneficial in treating a variety of diseases, such as cardiovascular diseases, which could include hypertension, atherosclerosis, and congestive heart failure. In particular, nebivolol and its key metabolites have effects on NO metabolism, independent of β 1 -selective interactions and the favorable effects of nebivolol metabolites on endothelial NO release has implications for its use in the treatment of cardiovascular disorders. This invention describes hydroxylated nebivolol metabolites, compositions comprising at least one hydroxyl nebivolol metabolite and methods of using such compositions to treat and/or prevent cardiovascular diseases or disorders. 
     BACKGROUND OF THE INVENTION 
     The normal production of endothelial nitric oxide is important for maintenance of vascular function. Increasing endothelial NO release results in a reduction in smooth muscle cell contractility and decreased vascular resistance. Under conditions of hypertension and hyperlipidemia, however, endothelial dysfunction produces a marked decrease in NO release, resulting in: 1) increased vasoconstriction and vasospasm; 2) greater monocyte and LDL infiltration; 3) proliferation of vascular smooth cells; 4) increased oxidative stress; and 5) increased platelet aggregation. It has been suggested that substances that restore endothelial function and NO metabolism have benefit in the treatment of various cardiovascular disorders, including coronary artery disease and heart failure. 
     SUMMARY OF THE INVENTION 
     Hydroxylated nebivolol metabolites increase NO release from human endothelial cell preparations in a concentration dependent fashion following acute administration. In addition, several hydroxylated nebivolol metabolites, including but not limited to 4-hydroxy-6,6′difluoro-, 4-hydroxy-5-phenol-6,6′difluoro-, and 4-hydroxy-8-pheno-6,6′difluoro-, have the ability to increase the capacity for NO release in human endothelial cells following chronic administration. This invention provides hydroxylated nebivolol metabolites and compositions comprising nebivolol and/or at least one hydroxylated metabolite of nebivolol and/or at least one compound used to treat cardiovascular diseases or a pharmaceutically acceptable salt thereof. In addition, this invention provides methods of treating and/or preventing vascular diseases characterized by nitric oxide insufficiency, by administering at least one hydroxylated metabolite of nebivolol that is capable of releasing a therapeutically effective amount of nitric oxide to a targeted site affected by the vascular disease. Also, this invention is directed to the treatment and/or prevention of migraine headaches administering at least one hydroxylated metabolite of nebivolol. This invention may also be used in conjunction with or as a single treatment of metabolic syndrome disorders.

If it is administered prior to clinical manifestation of the unwanted condition (e.g., disease or other unwanted state of the host animal) then the treatment is prophylactic, i.e., it protects the host against developing the unwanted condition, whereas if administered after manifestation of the unwanted condition, the treatment is therapeutic (i.e., it is intended to diminish, ameliorate or maintain the existing unwanted condition or side effects therefrom). 
     The term “structure-activity relationship” or “(SAR)” is art-recognized and refers to the way in which altering the molecular structure of a drug or other compound alters its interaction with a receptor, enzyme, nucleic acid or other target and the like. 
     It will be understood that “substitution” or “substituted with” includes the implicit proviso that such substitution is in accordance with permitted valence of the substituted atom and the substituent, and that the substitution results in a stable compound, e.g., which does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, or other reaction.

The phrase “therapeutically-effective amount” means that amount of such a substance that produces some desired local or systemic effect at a reasonable benefit/risk ratio applicable to any treatment. The therapeutically effective amount of such substance will vary depending upon the subject and disease condition being treated, the weight and age of the subject, the severity of the disease condition, the manner of administration and the like, which can readily be determined by one of ordinary skill in the art. 
     The term “treating” is art-recognized and refers to curing as well as ameliorating at least one symptom of any condition or disease. 
     The term “metabolite” or “nebivolol metabolite” as used herein includes hydroxyl substitution at one or more of positions 3-8 and 3′-8′, wherein positions 3-8 and 3′-8′ shown on the parent nebivolol compound may each independently be hydroxyl groups, while positions 3-8 and 3′-8′ may each independently be halogen atoms, such as fluorine, or each independently be hydrogen atoms. For example, the compound may be mono-hydroxylated at the 4,4′, 5,5′ 8, or 8′ positions and di-fluorinated at the 6 and 6′ positions. In another example, the compound could also be di-hydroxylated at the 4,5′; 4′, 5; 4,8′; 4′,8, or 4′,8′ positions and be di-fluorinated at the 6 and 6′ positions in all of these instances. This invention envisions and includes within its scope all such structural isomers and stereoisomers and mixtures thereof, and those not explicitly described. The terms “metabolite” and “nebivolol metabolite” envision and includes within its scope all such structural isomers and stereoisomers and mixtures thereof, and those not explicitly described. 
     The phrase “therapeutic effect” is art-recognized and refers to a local or systemic effect in animals, particularly mammals, and more particularly humans caused by a pharmacologically active substance. The term thus means any substance intended for use in the diagnosis, cure, mitigation, treatment or prevention of disease or in the enhancement of desirable physical or mental development and/or conditions in an animal or human. The phrase “therapeutically-effective amount” means that amount of such a substance that produces some desired local or systemic effect at a reasonable benefit/risk ratio applicable to any treatment. The therapeutically effective amount of such substance will vary depending upon the subject and disease condition being treated, the weight and age of the subject, the severity of the disease condition, the manner of administration and the like, which can readily be determined by one of ordinary skill in the art. 
     The parent nebivolol compound and its hydroxylated metabolites can be synthesized by one skilled in the art following the methods described in, for example, U.S. Pat. Nos. 4,654,362, 5,759,580, 6,075,046, 6,545,040 and in EP 0 145 067, EP 0 334 429, and in WO 95/22325 and WO 96/19987; Van Lommen et al., J. Pharm. Belg., 45(6): 355-360 (1990); Chandrasekhar, S. et al., Tetrahedron, 56(34): 6339-6344 (2000); and Kendrick et al., J. Chromatogram. A., 729: 341-354 (1996); the disclosure of each of which are incorporated by reference herein in their entirety. 
     The hydroxylated metabolites may also be prepared by the synthetic procedures found in Appendix 1. Reactions are performed in solvents appropriate to the reagents, and materials used are suitable for the transformations being effected. It is understood by one skilled in the art of organic synthesis that the functionality present in the molecule must be consistent with the chemical transformation proposed. This will, on occasion, necessitate judgment by the scientist as to the order of synthetic steps, protecting groups required, and deprotection conditions. Substituents on the starting materials may be incompatible with some of the reaction conditions required in some of the methods described, but alternative methods and substituents compatible with the reaction conditions will be readily apparent to one skilled in the art. The use of sulfur and oxygen protecting groups is known in the art for protecting thiol and alcohol groups against undesirable reactions during a synthetic procedure and many such protecting groups are known, e.g., T. H. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, John Wiley &amp; Sons, New York (1999), which is incorporated herein in its entirety. 
     The hydroxylated metabolites have basic properties and, consequently, they may be converted to their therapeutically active non-toxic acid addition salt forms by treatment with appropriate acids, such as, for example, inorganic acids, such as hydrohalic acid, e.g. hydrochloric, hydrobromic and the like, and sulfuric acid, nitric acid, phosphoric acid and the like; or organic acids, such as, for example, acetic, propanoic, hydroxyacetic, 2-hydroxypropanoic, 2-oxopropanoic, ethanedioic, propanedioic, butanedioic, (Z)-2-butenedioic, (E)-2-butenedioic, 2-hydroxybutanedioic, 2,3-dihydroxybutanedioic, 2-hydroxy-1,2,3-propane-tricarboxylic, methanesulfonic, ethanesulfonic, benzenesulfonic, 4-methylbenzenesulfonic, cyclohexanesulfamic, 2-hydroxybenzoic, 4-amino-2-hydroxybenzoic and the like acids. Conversely, the salt form can be converted by treatment with alkali into the free base form. 
     Hydroxylated Nebivolol Metabolites 
     Hydroxylated metabolites of nebivolol have the ability to increase the capacity for NO release in human endothelial cells following (chronic) administration. While not being bound by theory, the hydroxylated metabolites of nebivolol are thought to function via activation of the L-arginine/nitric oxide pathway. They are endothelial-dependent vasodilatory agents with additional cardio-selective (i.e., beta-selective) blocking capacity, which have the potential to maintain endothelial function or improve endothelial dysfunction and be effective medications for the treatment of cardiovascular diseases, such as atherosclerosis, hypertension, coronary artery disease and congestive heart failure. Hydroxylated nebivolol metabolites could be used as a mono-therapy to treat or prevent the aforementioned disorders or in combination with other appropriate pharmaceutical agents either in the same dosage form/product or concomitantly administered as separate dosage forms/products to adequately treat/prevent the aforementioned disorders. Since these compounds have the capacity to increase endothelial nitric oxide concentrations, they may have added benefits in special populations such as diabetics, chronic smokers, Black-Americans, patients with acute coronary syndromes (ACS), coronary heart disease (CHD), metabolic syndrome and people suffering from obesity. 
     The direct endothelial benefit for the hydroxylated metabolites of nebivolol was observed at concentrations as low as 250 nM. By enhancing the ability of cells to release NO, these nebivolol metabolites may have strong vasodilatory effects and the ability to restore abnormalities in endothelial function associated with hypertension. Further, these metabolites have the potential for pronounced affects in special populations prone to cardiovascular disease, such as Black Americans, and these metabolites may have effects in HUVEC (Human Umbilical Vein Endothelial Cells) in concentrations as low as 250 nM. 
     The hydroxylated nebivolol metabolites are represented by the formula (I) 
     
       
         
         
             
             
         
       
     
     wherein positions 3-8 and 3′-8′ shown on the parent nebivolol compound may each independently be hydroxyl groups (and at least one of them is an —OH), while positions 3-8 and 3′-8′ may each independently be halogen atoms, such as fluorine, or each independently be hydrogen atoms. For example, the compound may be mono-hydroxylated at the 4,4′, 5,5′, 8, or 8′ positions and di-fluorinated at the 6 and 6′ positions. In another example, the compound could be di-hydroxylated at the 4,5′; 4′, 5; 4,8′; 4′,8, or 4′,8′ positions and be di-fluorinated at the 6 and 6′ positions in all of these instances. This invention envisions and includes within its scope all such structural isomers and stereoisomers and mixtures thereof, and those not explicitly described. 
     It is to be understood that the hydroxylated nebivolol metabolites can exist as the optically pure enantiomers, pure diastereomers, mixtures of enantiomers, mixtures of diastereomers, racemic mixtures of enantiomers, diastereomeric racemates or mixtures of diastereomeric racemates. It is to be understood that the compound has at a minimum 4 stereocenters, and if the pyran ring(s) is/are substituted with a hydroxyl functionality, the compound has minimum of 5 stereocenters. This inventions anticipates all combinations of stereoisomers. 
     For instance, the hydroxy-substituted nebivolol metabolites 4,5′-dihydroxy-6,6′-difluoro, 4,8′-dihydroxy-6,6′-difluoro- and 4-hydroxy-6,6′-difluoro-increase NO release from human endothelial cell in concentration dependent fashion following acute administration. For example, the 4,5′-dihydroxy-6,6′-difluoro-, and 4,8′-dihydroxy-6,6′-difluoro-are agonists of NO release, with a maximum of about 330-350 nM NO at a 50 μM drug concentration (see  FIGS. 1 and 2 ). The hydroxylated metabolites of nebivolol are thought to function as anti-oxidants and prevent lipid peroxidation. 
     Compositions Comprising Nebivolol 
     In part, the present invention features compositions comprising a nebivolol metabolite and at least one other cardiovascular agent. In addition, the present invention features compositions comprising a nebivolol metabolite and at least one other active agent. The amount of each cardiovascular agent and/or other active agent present in the compositions may vary depending on a number of variables such as age, weight, gender, and health related issues. In general, the dosage of the cardiovascular agents will generally be in the range of about 0.01 ng to about 10 g per kg body weight, specifically in the range of about 1 ng to about 0.1 g per kg, and more specifically in the range of about 100 ng to about 10 mg per kg. In another embodiment, the amount of nebivolol in the compositions of the present invention may be anywhere from about 0.125 mg to about 40 mg. When the other cardiovascular agent is an ACE inhibitor, the amount of the ACE inhibitor may be anywhere from 0.5 mg to about 80 mg. When the other cardiovascular agent is an ARB, the amount of ARB may be anywhere from about 1 mg to about 1200 mg. The amount of the other cardiovascular agent will depend in part on the particular cardiovascular agent used. 
     In addition to ACE inhibitors and ARBs, additional cardiovascular agents include, but are not limited to adrenergic blockers, adrenergic agonists, agents for pheochromocytoma, antianginal agents, antiarrhythmics, antiplatelet agents, anticoagulants, antihypertensives, antilipemic agents, antidiabetics, antiinflanunatory agents, calcium channel blockers, CETP inhibitors, COX-2 inhibitors, direct thrombin inhibitors, diuretics, endothelin receptor antagonists, HMG Co-A reductase inhibitors, inotropic agents, rennin inhibitors, vasodilators, vasopressors, AGE crosslink breakers (advanced glycosylation end-product crosslink breakers, such as alagebrium, see U.S. Pat. No. 6,458,819), and AGE formation inhibitors (advanced glycosylation end-product formation inhibitors, such as pimagedine). Cardiovascular agents falling within these general categories are exemplified by the following: 
     “Angiotensin I Converting Enzymes (ACE&#39;s) and Angiotensin II Receptor Antagonists (ARB s)” 
     “Angiotensin II receptor antagonists” (ARB&#39;s) are compounds which interfere with the activity of angiotensin II by binding to angiotensin II receptors and interfering with its activity. Angiotensin I and angiotensin II are synthesized by the enzymatic renin-angiotensin pathway. The synthetic process is initiated when the enzyme renin acts on angiotensinogen, a pseudoglobulin in blood plasma, to produce the decapeptide angiotensin I. Angiotensin I is converted by angiotensin converting enzyme (ACE) to angiotensin II (angiotensin-[1-8] octapeptide). The latter is an active pressor substance which has been implicated as a causative agent in several forms of hypertension in various mammalian species, e.g., humans. 
     Angiotensin II receptor antagonists (ARB&#39;s) are well known and include peptide compounds and non-peptide compounds. Most angiotensin II receptor antagonists are slightly modified congeners in which agonist activity is attenuated by replacement of phenylalanine in position 8 with some other amino acid; stability can be enhanced by other replacements that slow degeneration in vivo. 
     Examples of angiotensin II receptor antagonists include: telmisartan; olmesartan; peptidic compounds (e.g., saralasin and related analogs); N-substituted imidazole-2-one (U.S. Pat. No. 5,087,634); imidazole acetate derivatives including 2-N-butyl-4-chloro-1-(2-chlorobenzile) imidazole-5-acetic acid (see Long et al., J. Pharmacol. Exp. Ther. 247(1), 1-7 (1988)); 4,5,6,7-tetrahydro-1H-imidazo[4,5-c]pyridine-6-carboxylic acid and analog derivatives (U.S. Pat. No. 4,816,463); N2-tetrazole beta-glucuronide analogs (U.S. Pat. No. 5,085,992); substituted pyrroles, pyrazoles, and tryazoles (U.S. Pat. No. 5,081,127); phenol and heterocyclic derivatives such as 1,3-imidazoles (U.S. Pat. No. 5,073,566); imidazo-fused 7-member ring heterocycles (U.S. Pat. No. 5,064,825); peptides (e.g., U.S. Pat. No. 4,772,684); antibodies to angiotensin II (e.g., U.S. Pat. No. 4,302,386); and aralkyl imidazole compounds such as biphenyl-methyl substituted imidazoles (e.g., EP 253,310, Jan. 20, 1988); ES8891 (N-morpholinoacetyl-(−1-naphthyl)-L-alanyl-(4, thiazolyl)-L-alanyl (35, 45)-4-amino-3-hydroxy-5-cyclo-hexapentanoyl-N-hexylamide, Sankyo Company, Ltd., Tokyo, Japan); SKF108566 (E-alpha-2-[2-butyl-1-(carboxy phenyl) methyl] 1H-imidazole-5-yl[methylane]-2-thiophenepropanoic acid, Smith Kline Beecham Pharmaceuticals, Pa.); Losartan (DUP753/MK954, DuPont Merck Pharmaceutical Company); Remikirin (RO42-5892, F. Hoffman LaRoche A G); A.sub.2 agonists (Marion Merrill Dow) and certain non-peptide heterocycles (G. D. Searle and Company). Other non-limiting examples of ARBs include candesartan, eprosartan, irbesartan, losartan, and valsartan. Other ARBs may be identified using standard assaying techniques known to one of ordinary skill in the art. 
     “Angiotensin converting enzyme” (ACE) is an enzyme which catalyzes the conversion of angiotensin Ito angiotensin II. ACE inhibitors include amino acids and derivatives thereof, peptides, including di- and tri-peptides and antibodies to ACE which intervene in the renin-angiotensin system by inhibiting the activity of ACE thereby reducing or eliminating the formation of pressor substance angiotensin II. ACE inhibitors have been used medically to treat hypertension, congestive heart failure, myocardial infarction and renal disease. Classes of compounds known to be useful as ACE inhibitors include acylmercapto and mercaptoalkanoyl prolines such as captopril (U.S. Pat. No. 4,105,776) and zofenopril (U.S. Pat. No. 4,316,906), carboxyalkyl dipeptides such as enalapril (U.S. Pat. No. 4,374,829), lisinopril (U.S. Pat. No. 4,374,829), quinapril (U.S. Pat. No. 4,344,949), ramipril (U.S. Pat.

Calcium channel blockers are a heterogeneous group of drugs that prevent or slow the entry of calcium into cells by regulating cellular calcium channels. (Remington, The Science and Practice of Pharmacy, Nineteenth Edition, Mack Publishing Company, Eaton, Pa., p. 963 (1995)). Most of the currently available calcium channel blockers, and useful according to the present invention, belong to one of three major chemical groups of drugs, the dihydropyridines, such as nifedipine, the phenyl alkyl amines, such as verapamil, and the benzothiazepines, such as diltiazem. Non-limiting examples of calcium channel blockers that may be used in the compositions of the present invention include bepridil, clentiazem, diltiazem, fendiline, gallopamil, mibefradil, prenylamine, semotiadil, terodiline, verapamil, amlodipine, aranidipine, barnidipine, benidipine, cilnidipine, efonidipine, elgodipine, felodipine, isradipine, lacidipine, lercanidipine, manidipine, nicardipine, nifedipine, nilvadipine, nimodipine, nisoldipine, nitrendipine, cinnarizine, flunarizine, lidoflazine, lomerizine, bencyclane, etafenone, fantofarone, perhexyline, and mixtures thereof.

See, J. Carter et al, Synthesis and activity of sulfonamide-substituted 4,5-diaryl thiazoles as selective cyclooxygenase-2 inhibitors.” Bioorg. Med. Chem. Lett Apr. 19, 1999: Vol. 9(8): 1171-74, and compounds referenced in the article “Design and synthesis of sulfonyl-substituted 4,5-diarylthiazoles as selective cyclooxygenase-2 inhibitors”, Bioorg. Med. Chem. Lett Apr. 19, 1999: Vol. 9(8): 1167-70.

Biol. Chem. 11397-11403 (2000). The meaning of COX-2 inhibitor in this invention includes the cyclo-oxygenase-2 selective compounds referenced in Mitchell et al, “Cyclo-oxygenase-2: pharmacology, physiology, biochemistry and relevance to NSAID therapy”, Brit. J. of Pharmacology (1999) vol. 128: 1121-1132, see especially p. 1126. The meaning of COX-2 inhibitor in this invention includes so-called NO-NSAIDs or nitric oxide-releasing-NSAIDs referred to in L. Jackson et al, “COX-2 Selective Nonsteroidal Anti-Inflammatory Drugs: Do They Really Offer Any Advantages?”, Drugs, June, 2000 vol. 59(6): 1207-1216 and the articles at footnotes 27, and 28. Also included in the meaning of COX-2 inhibitor in this invention includes any substance that selectively inhibits the COX-2 isoenzyme over the COX-1 isoenzyme in a ratio of greater than 10 to 1 and preferably in ratio of at least 40 to 1 as referenced in Winokur WO 99/20110, and has one substituent having both atoms with free electrons under traditional valence-shell-electron-pair-repulsion theory located on a cyclic ring (as in the sulfylamine portion of celecoxib), and a second substituent located on a different ring sufficiently far from said first substituent to have no significant electron interaction with the first substituent. The second substituent should have an electronegativity within such substituent greater than 0.5, or the second substituent should be an atom located on the periphery of the compound selected from the group of a halogen F, Cl, Br or I, or a group VI element, S or O. Thus for purposes of this last included meaning of a COX-2 inhibitor, one portion of the COX-2 inhibitor should be hydrophilic and the other portion lipophilic. Also included as a COX-2 inhibitor are compounds listed at page 553 in Pharmacotherapy: A Pathophysiologic Approach, Depiro et al (McGraw Hill 1999) including nabumetone and etodolac. Recognizing that there is overlap among the selective COX-2 inhibitors set out in this paragraph, the intent of the term COX-2 inhibitor is to comprehensively include all selective COX-2 inhibitors, selective in the sense of inhibiting COX-2 over COX-1. The inventors add to the class of COX-2 inhibitors useful in the invention the drug bearing the name etoricoxib referenced in the Wall Street Journal, Dec. 13, 2000, manufactured by Merck.

Another selective COX-2 inhibitor is DFU [5,5-dimethyl-3-(3-fluorophenyl)-4-(4-methylsulphonyl) phenyl-2(5H)-furanone] referenced in Yergey et al, Drug Metab. Dispos. 29(5):638-44 (May 2001). The inventors also include as a selective COX-2 inhibitor the flavonoid antioxidant silymarin, and an active ingredient in silymarin, silybinin, which demonstrated significant COX-2 inhibition relative to COX-1 inhibition. The silymarin also showed protection against depletion of glutathione peroxidase. Zhao et al, “Significant Inhibition by the Flavonoid Antioxidant Silymarin against 12-O-tetracecanoylphorbol 13-acetate-caused modulation of antioxidant and inflammatory enzymes, and cyclooxygenase 2 and interleukin-1 alpha expression in SENCAR mouse epidermis: implications in the prevention of stage I tumor promotion,” Mol. Carcinog. December 1999, Vol 26(4):321-33 PMID 10569809. Silymarin has been used to treat liver diseases in Europe. 
     A number of the above-identified COX-2 inhibitors are prodrugs of selective COX-2 inhibitors, and exert their action by conversion in vivo to the active and selective COX-2 inhibitors. The active and selective COX-2 inhibitors formed from the above-identified COX-2 inhibitor prodrugs are described in detail in WO 95/00501, published Jan. 5, 1995, WO 95/18799, published Jul. 13, 1995 and U.S. Pat. No. 5,474,995, issued Dec. 12, 1995. Given the teachings of U.S. Pat. No. 5,543,297, entitled: “Human cyclooxygenase-2 cDNA and assays for evaluating cyclooxygenase-2 activity,” a person of ordinary skill in the art would be able to determine whether an agent is a selective COX-2 inhibitor or a precursor of a COX-2 inhibitor, and therefore part of the present invention.

This development is however, not limited to flavonoid compounds isolated from plant, part of plant or extracts of  Astragalus  Membranaceus, but encompasses any suitable flavonoid compound isolated from different sources or chemically synthesized. In addition, any suitable known or not yet discovered flavonoid compound, and isoflavonoid compound, is within the scope of the present technology. A number of flavonoids and isoflavonoids are described in USDA-Iowa State University Database on the Isoflavone Content of Foods, Release 1.3-2002, and in USDA Database for the Flavonoid Content of Selected Foods—2003 (http://www.nal.usda. gov/fnic/foodcomp/Data/isoflav/isoflav.html) and (http://www.nal.usda.gov/fnic/foodcomp/Data/Flav/flav.html) (both of them herewith incorporated by reference). It will be evident to any skilled person how to choose the suitable flavonoid and/or isoflavonoid compound for the purpose of the present development. For example, flavonoid compounds for the purpose of the present development may be, but are not limited to, (−)-epictechin, (+)-catechin, procyanidin B2, quercetin dehydrate, taxifolin, resveratrol, and the like. 
     Carotenoids, which are generally are tetraterpenes originating from the mevalonate and deoxyxylulose phosphate pathways (older sources sometimes refer to their source as the ‘isoprenoid’ pathway). Two molecules of the C 20  compound geranylgeranyldiphosphate (GGDP) condense to form the symmetrical carotenoid skeleton. 
     Carotenoids are divided into two subclasses, i.e., more polar compounds called xanthophylls, or oxycarotenoids, and the nonpolar hydrocarbon carotenes. 
     Terms such as carotenoid analog and carotenoid derivative may generally refer to in some embodiments chemical compounds or compositions derived from a naturally occurring carotenoid or simply to synthetic carotenoids. In some embodiments, terms such as carotenoid analog and carotenoid derivative may generally refer to chemical compounds or compositions which are synthetically derived from non-carotenoid based parent compounds; however, which ultimately substantially resemble a carotenoid derived analog. In certain embodiments, terms such as carotenoid analog and carotenoid derivative may generally refer to a synthetic derivative of a naturally occurring carotenoid. Examples of carotenoids are provided in the book “Carotenoids Handbook,” edited by G. Britton et al, 2004, which is herein incorporated by reference.

     The compounds according to the invention may be formulated as pharmaceutical compositions suitable for oral, buccal, parenteral, transdermal or rectal administration or in a form suitable for administration by inhalation or insufflation. Parenteral administration includes subcutaneous injections, intravenous, intramuscular, intrasternal injection, or infusion techniques. 
     The pharmaceutical compositions may also be formulated as a therapeutically effective amount in a dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used in the specification and claims herein refers to physically discrete units suitable as unitary dosages, each unit containing a predetermined quantity of active ingredient calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. Examples of such dosage unit forms are tablets (including scored or coated tablets), capsules, pills, powder packets, wafers, injectable solutions or suspensions, teaspoonfuls, tablespoonfuls and the like, and segregated multiples thereof. Such dosage forms can also comprise, as in conventional practice, additional substances other than inert diluents, e.g., lubricating agents such as magnesium stearate. In the case of capsules, tablets, effervescent tablets, and pills, the dosage forms can also comprise buffering agents. Soft gelatin capsules can be prepared to contain a mixture of the active compounds or compositions of the invention and vegetable oil. Hard gelatin capsules can contain granules of the active compound in combination with a solid, pulverulent carrier such as lactose, saccharose, sorbitol, mannitol, potato starch, corn starch, amylopectin, cellulose derivatives of gelatin. Tablets and pills can be prepared with enteric coatings. 
     Liquid dosage forms for oral administration can include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs containing inert diluents commonly used in the art, such as water. Such compositions can also comprise adjuvants, such as wetting agents, emulsifying and suspending agents, and sweetening, flavoring, and perfuming agents. 
     Suppositories for vaginal or rectal administration of the compounds and compositions of the invention can be prepared by mixing the compounds or compositions with a suitable nonirritating excipient such as cocoa butter and polyethylene glycols which are solid at room temperature but liquid at body temperature, such that they will melt and release the drug. 
     Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions can be formulated according to the known art using suitable dispersing agents, wetting agents and/or suspending agents. The sterile injectable preparation can also be a sterile injectable solution or suspension in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be used are water, Ringer&#39;s solution, and isotonic sodium chloride solution. Sterile fixed oils are also conventionally used as a solvent or suspending medium. 
     The compositions of this invention can further include conventional excipients, i.e., pharmaceutically acceptable organic or inorganic carrier substances suitable for oral, buccal, parenteral, transdermal or rectal administration or in a form suitable for administration by inhalation or insufflation, which do not deleteriously react with the active compounds. Suitable pharmaceutically acceptable carriers include, for example, water, salt solutions, alcohol, vegetable oils, polyethylene glycols, gelatin, lactose, amylose, magnesium stearate, talc, surfactants, silicic acid, viscous paraffin, perfume oil, fatty acid monoglycerides and diglycerides, petroethral fatty acid esters, hydroxymethyl-cellulose, polyvinylpyrrolidone, and the like. The pharmaceutical preparations can be sterilized and if desired, mixed with auxiliary agents, e.g., lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, colorings, flavoring and/or aromatic substances and the like which do not deleteriously react with the active compounds. For parenteral application, particularly suitable vehicles consist of solutions, preferably oily or aqueous solutions, as well as suspensions, emulsions, or implants. Aqueous suspensions may contain substances that increase the viscosity of the suspension and include, for example, sodium carboxymethyl cellulose, sorbitol and/or dextran. Optionally, the suspension may also contain stabilizers. 
     Both tablets and capsules may also be manufactured in the form of sustained release formulations, such that they provide a controlled continuous release of the compounds according to the invention over a period of hours. 
     Administration of the compositions of the present invention will be in an amount sufficient to achieve a therapeutic effect as recognized by one of ordinary skill in the art. 
     The dosage of any compositions of the present invention will vary depending on the symptoms, age and body weight of the patient, the nature and severity of the disorder to be treated or prevented, the route of administration, and the form of the subject composition. Any of the subject formulations may be administered in a single dose or in divided doses. Dosages for the compositions of the present invention may be readily determined by techniques known to those of skill in the art or as taught herein. 
     The dosage range for nebivolol ranges from about 0.1 mg to about 100 mg per day. In another embodiment, the dosage range may be from about 0.75 mg to about 50 mg per day. In yet another embodiment, the dosage range may be from about 1.25 mg to about 10 mg per day. 
     In certain embodiments, the dosage of the co-active compounds will generally be in the range of about 0.01 ng to about 1 g per kg body weight, specifically in the range of about 1 ng to about 0.1 g per kg, and more specifically in the range of about 100 ng to about 10 mg per kg body weight. 
     An effective dose or amount, and any possible affects on the timing of administration of the formulation, may need to be identified for any particular composition of the present invention. This may be accomplished by routine experiment as described herein, using one or more groups of animals (preferably at least 5 animals per group), or in human trials if appropriate. The effectiveness of any subject composition and method of treatment or prevention may be assessed by administering the composition and assessing the effect of the administration by measuring one or more applicable indices, and comparing the post-treatment values of these indices to the values of the same indices prior to treatment. 
     The precise time of administration and amount of any particular subject composition that will yield the most effective treatment in a given patient will depend upon the activity, pharmacokinetics, and bioavailability of a subject composition, physiological condition of the patient (including age, sex, disease type and stage, general physical condition, responsiveness to a given dosage and type of medication), route of administration, and the like. The guidelines presented herein may be used to optimize the treatment, e.g., determining the optimum time and/or amount of administration, which will require no more than routine experimentation consisting of monitoring the subject and adjusting the dosage and/or timing. 
     While the subject is being treated, the health of the patient may be monitored by measuring one or more of the relevant indices at predetermined times during the treatment period. Treatment, including composition, amounts, times of administration and formulation, may be optimized according to the results of such monitoring. The patient may be periodically reevaluated to determine the extent of improvement by measuring the same parameters. Adjustments to the amount(s) of subject composition administered and possibly to the time of administration may be made based on these reevaluations. 
     Treatment may be initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage may be increased by small increments until the optimum therapeutic effect is attained. 
     The use of the subject compositions may reduce the required dosage for any individual agent contained in the compositions (e.g., the steroidal anti inflammatory drug) because the onset and duration of effect of the different agents may be complimentary. 
     Toxicity and therapeutic efficacy of subject compositions may be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., for determining the LD 50  and the ED 50 . 
     The data obtained from the cell culture assays and animal studies may be used in formulating a range of dosage for use in humans. The dosage of any subject composition lies preferably within a range of circulating concentrations that include the ED 50  with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. For compositions of the present invention, the therapeutically effective dose may be estimated initially from cell culture assays. 
     In general, the doses of an active agent will be chosen by a physician based on the age, physical condition, weight and other factors known in the medical arts. 
     Those of skill in treating subjects suffering from a vascular disease, for instance, an increased blood pressure, could easily determine the therapeutically effective amount from the test results presented hereinafter. In general it is contemplated that an effective daily dose of the compounds of formula (I) or their pharmaceutically acceptable acid-addition salts would be from about 0.01 mg/kg to about 50 mg/kg body weight, in particular from about 0.1 mg/kg to about 10 mg/kg body weight, and preferably from about 0.1 mg/kg to about 1 mg/kg body weight. 
     The invention also provides pharmaceutical kits comprising one or more containers filled with one or more of the ingredients of the pharmaceutical compounds and/or compositions of the invention, including, hydroxylated nebivolol metabolites. Such kits can also include, for example, other compounds and/or compositions (e.g., diuretics, digoxin, compounds used to treat cardiovascular diseases, therapeutic agents, permeation enhancers, lubricants, and the like), a device(s) for administering the compounds and/or compositions, and written instructions in a form prescribed by a governmental agency regulating the manufacture, use or sale of pharmaceuticals or biological products, which instructions can also reflects approval by the agency of manufacture, use or sale for human administration. 
     Another embodiment of the invention relates to the local administration of at least one hydroxylated metabolite of nebivolol, and, optionally, at least one additional therapeutic agent to treat injured tissue, such as damaged blood vessels. 
     The compounds of the present invention and, optionally, other therapeutic agents, can be incorporated into a natural or synthetic matrix which can then be applied with specificity to a biological site of interest. Accordingly the nebivolol metabolites are “bound to the matrix” which means that the nebivolol metabolite(s) along with other therapeutic agents are physically and/or chemically associated with part of, incorporated with, attached to, or contained within the natural or synthetic matrix. 
     Any of a wide variety of natural or synthetic polymers can be used as the matrix in the context of the invention. It is only necessary for the matrix to be biologically acceptable. Exemplary matrixes suitable for use in the invention are polymers including, for example, polyolefins (such as polystyrene, polypropylene, polyethylene, high density polyethylene, polytetrafluorethylene, polyvinylidene diflouride and polyvinylchloride), polyethylenimine or derivatives thereof, polyethers (such as polyethylene glycol), polyesters (such as poly-L-lactic acid, poly-D, L-lactic, poly-D-lactic, polyglycolic, poly-(lactide/glycolide)), polyanhydrides, polyhydroxybutyrates, polyamides (such as nylon), polyurethanes, polyurethane copolymers (such as pellethane polymers), polyacrylates (such as polymethacrylate, poly (2-(methacryloyloxyethyl)-2′-(trimethylammonium)ethyl phosphate inner salt-co-n-dodecyl methacrylate), mixtures of polymers (such as polylactic acid/polylysine copolymers, polyurethane/polyester copolymers, polyurethane/polyether copolymers, nylon/polyether copolymers, such as vestamid), biopolymers (such as peptides, proteins, oligonucleotides, antibodies, peptide hormones, glycoproteins, glycogen and nucleic acids), starburst dendrimers, natural fibrous matrix (such as filter paper), synthetic fibrous matrix materials (such as three-dimensional lattice of synthetic polymers and copolymers) and the like. Exemplary polymers are described in U.S. Pat. Nos. 5,705,583, 5,770,645 and 5,994,444, the disclosures of which are incorporated by reference herein in their entirety. 
     The physical and structural characteristics of the matrixes suitable for use in the invention are not critical, but depend on the application. It will be appreciated by one skilled in the art that where the matrix-metabolite of nebivolol composition of the invention is intended for local, relatively short term administration or similar administration they need not be biodegradable. For some uses, such as postangioplasty, coronary bypass surgery or intimal hyperplasia associated with vascular graft implants or the like, it may be desirable for the matrix to slowly dissolve in a physiological environment or to be biodegradable or bioresorbable. 
     In preventing and/or treating cardiovascular diseases or disorders, the nebivolol metabolites of the present invention and optionally at least one therapeutic agent can be administered directly to the damaged vascular surface intravenously by using an intraarterial or intravenous catheter, suitable for delivery of the compounds to the desired location. The location of damaged arterial surfaces is determined by conventional diagnostic methods, such as X-ray angiography, performed using routine and well-known methods available to one skilled in the art. 
     When administered in vivo, the compounds and compositions of the invention can be administered in combination with pharmaceutically acceptable carriers and in a therapeutically effective dosage, as described herein. 
     When the compounds and compositions of the present invention are administered as a mixture of at least one hydroxylated nebivolol metabolite, they can also be used in combination with one or more additional therapeutic agents which are known to be effective against the specific disease state targeted for treatment, such as for example diuretics and/or different antihypertensive agents such as beta-blockers, calcium channel blockers or ACE inhibitors. It is to be understood that such combination therapy constitutes a further aspect of the present invention. 
     “Concurrent administration” encompasses simultaneous or sequential treatment with the components of the combination, as well as regimens in which the drugs are alternated, or wherein one component is administered long-term and the other(s) are administered intermittently. Components can be administered in the same or in separate compositions, and by the same or different routes of administration. 
     The nebivolol metabolites of the present invention may be used in combination with other drugs that are used in the treatment/prevention/suppression or amelioration of the diseases or conditions for which the hydroxylated nebivolol metabolites are useful. Other drugs include, for example, an antithrombogenic agent, a thrombolytic agent, a fibrinolytic agent, a vasospasm inhibitor, a potassium channel activator, a calcium channel blocker, an antihypertensive agent, an antimicrobial agent, an antibiotic, an antiplatelet agent, an antimitotic agent, an antiproliferative agent, a microtubule inhibitor, an antisecretory agent, a remodelling inhibitor, an antisense nucleotide, an anti-cancer chemotherapeutic agent, a steroid, a non-steroidal antiinflammatory agent, a selective COX-2 inhibitor, an immunosuppressive agent, a growth factor antagonist or antibody, a dopamine agonist, a radiotherapeutic agent, a biologic agent, an angiotensin converting enzyme inhibitor, an angiotensin II receptor antagonist, a renin inhbitior, a free radical scavenger, an iron chelator, an antioxidant, a sex hormone, an antipolymerase, an antiviral agent, a photodynamic therapy agent, an antibody targeted therapy agent, a gene therapy agent, biphosphonates or other osteoporosis agents, cholesterol lowering agents, including but not limited to statins, niacin, or gemfibrozil, or mixtures thereof. 
     Such other drugs may be administered, by a route and in an amount commonly used therefore, contemporaneously or sequentially with a compound of the hydroxylated nebivolol metabolites. When a nebivolol metabolite of the present invention is used contemporaneously with one or more other drugs, a pharmaceutical composition containing such other drugs in addition to the compound of the present invention is preferred. Accordingly, the pharmaceutical compositions of the present invention include those that also contain one or more other active ingredients, in addition to the nebivolol metabolite of the present invention.

     Administration of a Nebivolol Metabolite with a Blood Pressure Reducing Agent 
     The nebivolol metabolites of the present invention and the acid addition salts thereof may be administered before, during or after the administration of a blood pressure reducing agent provided that the time of the administration of the compounds of the present invention in relation to the administration of the blood pressure reducing agent allows the compound of the present invention to be effective in potentiating the effects of the blood pressure reducing agent. 
     As blood pressure reducing agents of which the activity is potentiated there may be mentioned agents having adrenergic and/or vasodilating activity. In particular such agents may be the compounds mentioned in U.S. Pat. Nos. 3,663,607 and 3,836,671, in particular atenolol; U.S. Pat. Nos. 3,337,628 and 3,520,919, in particular propranolol; U.S. Pat. No. 3,873,600, in particular metoprolol; U.S. Pat. No. 3,511,836, in particular prazosin; U.S. Pat. No. 2,484,029, in particular hydralazine; U.S. Pat. No. 2,928,829 in particular guanethidine; U.S. Pat. No. 2,503,059, in particular phentolamine; U.S. Pat. No. 3,261,859, in particular verapamil; U.S. Pat. No. 3,485,847 in particular nifedipine; U.S. Pat. No. 3,910,924, in particular carteolol; German Pat. Nos. 2,458,624 and 2,458,625, in particular celiprolol. All cited patents are incorporated herein by reference. These groups of active ingredients are listed with the purpose of providing representative examples but not with the purpose of restricting the scope of the present invention. 
     Preferably a nebivolol metabolite of the present invention and the blood pressure reducing agent are administered in the form of suitable compositions. Said compositions are meant to also comprise products containing a nebivolol metabolite as defined herein and a blood-pressure reducing agent as a combined preparation for simultaneous, separate, timed-release of either or both components, or sequential use in blood-pressure reducing therapy. Such products may, for example, comprise a kit comprising a container with a suitable composition containing a nebivolol metabolite of the present invention and another container containing a composition with a blood pressure reducing agent. Such a product may have the advantage that the physician wishing to administer blood pressure reducing therapy can select, based on the diagnosis of the patient to be treated, the appropriate amounts of both components and the sequence of administration. 
     When administered during the administration of the blood pressure reducing agent, a composition containing both the blood pressure reducing agent and the active ingredient of a nebivolol metabolite of the present invention may particularly be convenient. 
     In a further aspect of the present invention there may be provided a composition comprising an amount capable of potentiating the effects of blood pressure reducing agents of a nebivolol metabolite of the present invention as defined herein and a blood pressure reducing agent. In the said composition, the molar ratio between the nebivolol metabolite and the blood pressure reducing agent may be other than about 1:1, or may be about 1:1. The amount of the active ingredient of the nebivolol metabolite in such a composition will be such that a potentiation of the effects of the blood-pressure reducing agent is obtained; the amount of the blood pressure reducing agent will be such that when potentiated, a blood pressure reducing effect is obtained upon administration. In particular, it is contemplated that the molar ratio of the compound of formula (I) to the blood pressure reducing compound may be situated between about 50:1 and about 1:50, in particular between about 20:1 and about 1:20, or between about 10:1 and about 1:10, or between about 5:1 and about 1:5, more particularly between about 2:1 and about 1:2. Particular such compositions are those wherein the blood pressure reducing agent is one of the agents pertaining to the patents cited hereinabove, and more particularly the agents specifically mentioned herein. 
     The present invention also provides a composition comprising a pharmaceutically acceptable carrier and, as active ingredient, an amount capable of potentiating the effects of blood pressure reducing agents of a nebivolol metabolite of the present invention or a pharmaceutically acceptable acid-addition salt thereof, as defined herein. 
     To prepare such pharmaceutical compositions, an effective amount of the particular compound or compounds, in base or acid-addition salt form, as the active ingredient or active ingredients is combined in intimate admixture with a pharmaceutically acceptable carrier, which carrier may take a wide variety of forms depending on the form of preparation desired for administration. These pharmaceutical compositions are desirably in unitary dosage form suitable, preferably, for administration orally, rectally or by parenteral injection. For example, in preparing the compositions in oral dosage form, any of the usual pharmaceutical media may be employed, such as, for example, water, glycols, oils, alcohols and the like in the case of oral liquid preparations such as suspensions, syrups, elixirs and solutions; or solid carriers such as starches, sugars, kaolin, lubricants, binders, disintegrating agents and the like in the case of powders, pills, capsules and tablets. Because of their ease in administration, tablets and capsules represent the most advantageous oral dosage unit form, in which case solid pharmaceutical carriers are obviously employed. For parenteral compositions, the carrier will usually comprise sterile water, at least in large part, though other ingredients, for example, to aid solubility, may be included. Injectable solutions, for example, may be prepared in which the carrier comprises saline solution, glucose solution or a mixture of saline and glucose solution. Injectable suspensions may also be prepared in which case appropriate liquid carriers, suspending agents and the like may be employed. In the compositions suitable for percutaneous administration, the carrier optionally comprises a penetration enhancing agent and/or a suitable wetting agent, optionally combined with suitable additives of any nature in minor proportions, which additives do not cause a significant deleterious effect to the skin. Said additives may facilitate the administration to the skin and/or may be helpful for preparing the desired compositions. These compositions may be administered in various ways, e.g., as a transdermal patch, as a spot-on, as an ointment. Acid addition salts of the nebivolol metabolites of the present invention, due to their increased water solubility over the corresponding base form, are obviously more suitable in the preparation of aqueous compositions. 
     The present invention also concerns a method of potentiating the effects of blood pressure reducing agents in warm-blooded animals in need of blood pressure reducing medication, said method comprising administering to said warm-blooded animals of an effective amount of a blood pressure reducing agent and a nebivolol metabolite of the present invention, as defined hereinabove. 
     Or alternatively, the present invention concerns a method of lowering the blood pressure in warm-blooded animals suffering therefrom, said method comprising administering to said warm-blooded animals of an effective amount of a blood pressure reducing agent and a nebivolol metabolite as defined hereinabove. 
     Those of skill in treating subjects suffering from an increased blood pressure could easily determine the safe and effective amount from the test results presented hereinafter. In general it is contemplated that an effective daily dose of the nebivolol metabolites of the present invention or their pharmaceutically acceptable acid-addition salts would be from 0.01 mg/kg to 50 mg/kg body weight, in particular from 0.1 mg/kg to 10 mg/kg body weight, and preferably from 0.1 mg/kg to 1 mg/kg body weight. 
     Nebivolol Metabolites and Nitric Oxide Release from Normotensive Black American and White Donors 
     A higher prevalence of cardiovascular risk factors, especially hypertension, has been observed among Black Americans in the United States. The increased CV risk among Black Americans may be attributed to differences in vascular physiology, including reduced NO bioavailability. In support of this concept, a clinical evaluation of brachial artery activity demonstrates reduced responsiveness of conductance vessels to both endogenous and exogenous NO in healthy Black Americans, as compared with age-matched Whites. The basis for this difference is due to the low bioavailability of NO from endothelium of Black Americans, despite much higher levels of endothelial-dependent NO synthase (eNOS). The cellular basis for this paradox is the finding that excessive O 2   −  generation by NAD(P)H-oxidase and uncoupled eNOS resulted in the loss of functional NO due to its reactivity with O 2   − , resulting in peroxynitrite (ONOO − ) formation, a potent oxidant. 
     Six stereoselective hydroxy metabolites significantly enhanced NO bioavailability in endothelial cells from both white and black American donors ( FIG. 7 ). Several metabolites had NO release activity that was dramatically greater than nebivolol, and even l-nebivolol due to key placements of hydroxyl substituents on the nebivolol molecule. Thus, steoselective hydroxy metabolites of nebivolol are potent stimulants of NO release from human endothelial cells. Also, certain hydroxy metabolites have NO release activity that is dramatically greater than nebivolol or l-nebivolol due to select hydroxyl substituents. 
     Experimental details: Acute treatment with six stereoselective hydroxy metabolites in endothelial cells from both white and black American donors shows that all six hydroxy metabolites have activity that is much superior to d-nebivolol, and most are superior to nebivolol racemate. As compared to nebivolol, the 4′(R)-hydroxy-7-fluoro-6-hydroxy-l-nebivolol metabolite causes a nearly two-fold increase in NO release to 476±20 and 383±18 nmol/L, respectively, from white and black donors. The 4′(R)-hydroxy-5-fluoro-l-nebivolol metabolite also exceeds the activity of nebivolol and even l-nebivolol by &gt;50%. These findings indicate that hydroxy metabolites of nebivolol have distinct and highly reproducible effects on acute NO release in human endothelial cells.

     In Table 1 and  FIG. 7 , the comparative effects of nebivolol, d-nebivolol, l-nebivolol and six stereoselective hydroxy metabolites on NO release are shown for cells harvested from white (open bars) and black American (solid bars) donors. The release of the NO from these endothelial cells was evaluated with electrochemical nanosensors placed within close proximity to the cell surface. All six hydroxy metabolites have activity that is significantly greater than d-nebivolol, and four are superior to nebivolol racemate. As compared to nebivolol, the 4(R)-hydroxy-7-fluoro-6-hydroxy-l-nebivolol (1689-64A) metabolite causes a nearly two-fold increase in NO release to 476±20 and 383±18 nmol/L, respectively, from white and black donors. The 4′(R)-hydroxy-5-fluoro-l-nebivolol metabolite (1689-64B) also exceeds the activity of l-nebivolol by &gt;50%. The metabolite with the least activity is similar to nebivolol. These findings indicate that hydroxy metabolites of nebivolol have distinct and highly reproducible effects on acute NO release in human endothelial cells. 
     Other Pharmacological Examples 
     Methods and Materials: Measurements of NO Release from Human Endothelium 
     All measurements presented are recorded in vitro using a sensitive porphyrinic probe. NO release is measured directly from human umbilical vein endothelial cells (HUVEC). HUVEC cells were obtained from American Type Culture Collection (Manassas, Va.) and grown in Ham&#39;s F12K medium with 2 mM L-glutamine adjusted to contain 1.5 g/l sodium bicarbonate and supplemented with 0.1 mg/ml heparin and 0.03-0.05 mg/ml endothelial cell growth supplement (ECGS)=10% fetal bovine serum. The HUVEC cells were kept in an atmosphere of elevated CO 2  concentration (5%). Nebivolol, its enantiomers, and nebivolol metabolites including the nebivolol glucuronides, 4-hydroxy-5′ phenol metabolite, 4-hydroxy-8′-phenol metabolite, 4-hydroxy, 5-hydroxy, 8-hydroxy metabolites, N-DAD, N-DACA and N-DAAA, are obtained from Mylan Laboratories (Morgantown, W. Va.) 
     All measurements of endothelial NO release are conducted in Hank&#39;s balance solution at 37° C. Cell wells are transferred to a Faraday cage and a porphyrinic sensor (diameter 0.5 mm) is positioned at a distance of 5±2 μm from the surface of the endothelial cells using an inverted microscope (Leica Microsystems, Wetzler, Germany) and a computer-assisted micromanipulator. The sensor operates with a three-electrode system: nanosensor (working electrode), saturated calomel electrode (reference electrode) and platinum wire (counter electrode, 0.5 mm diameter). The three electrodes are connected to a potentiostat/galvanostat PAR273. The baseline is stabilized after about 20 seconds. The test compounds are injected with a nanoinjector on to the surface of the cells following solubilization in buffer. The current proportional to the NO concentration is measured with the sensor, which operates in amperometric mode at a constant potential of 0.63V. Data are acquired with the use of an IBM computer with custom software and amperograms (current vs. time curves) and are recorded with a Guniry FAS1 Femtostat (Warminster, Pa.). 
     Nanosensors are prepared from carbon fibers. The size of the tip of carbon fiber is reduced from 6 μm to less than 1 μm by temperature controlled burning. The sensors are sensitized to NO by deposition of electrically conductive polymeric porphyrin and covered with a thin layer of Nafion. The prophyrinic microsensor has a response time of 0.1 ms at a micromolar NO concentration and 10 ms at the detection limit of 1 nM. 
     The nanosensor for NO is calibrated using saturated solution (concentration 1.82 mM verified with the coulometric method). Linear calibration curves are constructed for each sensor from 5× to 3×NO before and after measurements of cell activity. The data are presented as the mean±SEM for each of the triplicate measurements. The data (calculation and plotting) are transferred to Microcal Origin Software (OriginLab Corp., Northampton, Mass.). 
     The HUVEC preparation is stable over the course of these experiments with the cells remaining viable in culture for &gt;24 hours. Under non-stimulating conditions, basal levels of NO release are very low (&lt;30 nM). Measurement of NO release as a function of treatment is conducted in individual endothelial cells. Multiple measurements of NO release can be conducted on single cells following a brief refractory period. For robust statistical analysis, separate cells are used for each concentration and type of drug used in these analyses. 
     Comparative Effects of Acute Treatment with Nebivolol Metabolites on NO Release from Human Endothelial Cells 
     The results of these analyses demonstrate that six metabolites of the B i -adrenoceptor-selective antagonist nebivolol have different effects on NO release from human endothelial cells over a range of concentrations.  FIG. 3  compares peak NO release from HUVEC preparations for the six metabolites following addition of the agents at a concentration of 10 μM. It is apparent from this figure that the metabolites have quantitatively different effects on NO release under identical experimental conditions. At a relatively high concentration of 10 μM, only one metabolite (4-hydroxy nebivolol) produced NO levels that exceed 40004 whereas three of the metabolites (N-DAD, N-DACA and N-DAAA) stimulate less than 90 nM peak NO levels, even at this relatively high concentration. The remaining two metabolites (5-hydroxy and 8-hydroxy nebivolol) have intermediate effects on NO release of approximately 220 nM NO at a concentration of 10 μM. The dihydroxy nebivolol metabolites, including the 4-hydroxy-5′-phenol and 4-hydroxy-8′-phenol, as well as glucuronidated metabolites, are all active in regards to NO releasing capacity. 
     The NO releasing effects of certain nebivolol metabolites are then compared directly to acetylcholine, nebivolol and the nebivolol enantiomers in  FIG. 4 . These data show that the metabolite, 4-hydroxy nebivolol, has the greatest NO releasing effects compared to nebivolol or its enantiomers. At an identical concentration of 5 μM, the release of NO by 4-hydroxy nebivolol exceeds 400 nM whereas nebivolol produces approximately a 225 nm level of NO peak release. Interestingly, 4-hydroxy nebivolol demonstrates an NO releasing effect that approximates values measured with acetylcholine, the natural mediator for NO release from the endothelium. The release of endothelial NO following treatment with either 5-hydroxy or 8-hydroxy nebivolol is similar to that for the parent nebivolol compound and its enantiomers, as shown in  FIGS. 1-6 . 
     In  FIG. 6 , the most efficacious metabolite, 4-hydroxy nebivolol, is compared to the parent nebivolol compound and its enantiomers. Consistent with the previous figures, there are significant differences in the relative potency and efficacy of the agents when administered under identical experimental conditions. Comparing nebivolol and the other metabolites, 4-hydroxy nebivolol exhibits the greatest NO releasing effects over a broad range of drug concentrations with an EC 50  of 500 nm. Comparing treatment with the parent compound or its enantiomers, significant differences in efficacy are observed for 4-hydroxy nebivolol at concentrations as low as 500
